Summary of the Invention
Problems that the Invention is to Solve
[0004]
　However, Patent Documents 1 and 2, the form of the joint surface of the metal member does not disclose the effect on bond strength. In this art, a method of manufacturing a composite member having excellent bonding strength, and, has been desired composite member having excellent bonding strength.
Means for Solving the Problems
[0005]
　Method of producing a composite member according to one aspect of the present invention is a method for producing a composite member formed by joining the base material and the resin member, the surface of the base, the surface treatment for forming irregularities of the micro-order or nano-order and a step, on the surface of the base having irregularities formed by the surface treatment step, a bonding step of bonding the resin member directly by injection molding, a.
[0006]
　In this manufacturing method, the surface of the base to be bonded directly with the resin member is uneven micro-order or nano-order is formed. When the resin member is cured enters the unevenness of the micro-order or nano order, the strong anchoring effect occurs than in the case of irregularities of the millimeter order. Therefore, this manufacturing method, it is possible to produce a composite member having a high joint strength.
[0007]
　Arithmetic mean slope of the surface of the base material on which irregularities are formed in the surface treatment step may be from 0.17 to 0.50. The arithmetic mean slope, separate the measurement curve in the transverse direction at a constant interval, the absolute value of the slope of a line connecting the beginning to end points of the measurement curve in each interval (angle) obtained by averaging the absolute value of each section it is. The root mean square slope of the surface of the base material on which irregularities are formed in the surface treatment step may be from 0.27 to 0.60. Root mean square slope is calculated by the root mean square slope at all points of the defined area. Root mean the square slope, separate the measurement curve in the transverse direction at a constant interval, the mean square value of the slope of a line connecting the beginning to end points of the measurement curve in each interval (angle) determined is the square root of the value . Thus, by controlling the parameter indicating how much inclined in a narrow space, it is possible to produce a composite member having a high joint strength.
[0008]
　Surface treatment step may be a step of forming irregularities by blasting. In this case, as compared with other surface treatment techniques for joining members, the surface structure of the joint surface is quantitatively controllable, it is possible to perform surface treatment cost and in a short time.
[0009]
　Injection pressure in blasting may be 0.5 ~ 2.0 MPa. Particle diameter of the injection material in the blasting may be 30 ~ 300 [mu] m. Such blasting conditions, the unevenness of optimal micro-order or nano order can be formed on the surface of the base.
[0010]
　The material of the base material, metal, glass, or a ceramic or resin. On the surface of the base by forming an uneven micro-order or nano order, the metallic material of the base material, glass, be either a ceramic or a resin, to produce a composite member having a high joint strength can.
[0011]
　Composite member according to another aspect of the present invention comprises a base material having an uneven micro-order or nano order on the surface thereof, a resin member in direct contact with the surface of the base, a.
[0012]
　The composite member, since the micro-order or unevenness of nano-order of the surface of the base resin member are in direct contact, strong anchoring effect occurs than in the case of the base material having the unevenness of the millimeter order. Therefore, this composite member has excellent bonding strength.
[0013]
　Arithmetic mean slope of the surface of the base material, it may be from 0.17 to 0.50. The root mean square slope of the surface of the base material, it may be 0.27 to 0.60. This composite member is a parameter indicating the how much inclined in a narrow space is controlled irregularities are formed, has excellent bonding strength.
[0014]
　Material of the base material, metal, glass, or may be a ceramic or a resin. Since the surface of the micro-order or unevenness of nano-order of the base material is formed, the metal material of the base material is glass, be either a ceramic or a resin, the composite member has excellent bonding strength.

DESCRIPTION OF THE INVENTION
[0017]
　Hereinafter, with reference to the accompanying drawings, embodiments will be described. In the following description, the same reference numerals denote the same or corresponding elements, and overlapping description is omitted. Further, "bonding strength" in the present embodiment is described as "shear strength".
[0018]
[Composite Member]
　FIG. 1 is a perspective view showing a composite member 1 according to the embodiment. As shown in FIG. 1, the composite member 1 is a member in which a plurality of members are integrated by bonding. For example, the composite member 1 and the resin member is a member which is bonded to the heterologous member to the resin member. The heterologous member to the resin member, thermal expansion coefficient, heat transfer coefficient, such as strength is a member formed of a material having different properties to the resin member.
[0019]
　Composite member 1 comprises a base material 2 and the resin member 3. Base material 2 is a plate-like member as an example. Resin member 3 is in direct contact with the surface of the base 2. In Figure 1, the resin member 3, a portion of the surface of the base material 2 is in direct contact with the (contact surface 4 base material 2), has a lap joint structure. Material of the base material 2 is a metal, glass, ceramics or resin. Material of the resin member 3, polybutylene terephthalate, a resin polyphenyl sulfide, polyamide, liquid crystal polymer, polypropylene, acrylonitrile butadiene styrene.
[0020]
　Figure 2 is a cross-sectional view of the composite member 1 along the line II-II of Figure 1. As shown in FIG. 2, the base material 2 has an uneven 2b to part of the surface 2a (the contact surface 4). Unevenness 2b is the unevenness of the micro-order or nano-order. The unevenness of micro order, an uneven with height difference of less than 1 [mu] m 1000 .mu.m. The unevenness of the nano-order, an uneven with height difference of less than 1 nm 1000 nm. As a more specific example, in a part of the surface 2a (the contact surface 4), JIS B0601 (1994) to a defined as the arithmetic average roughness Ra, the maximum height Ry, and, the ten-point average roughness Rz, respectively 0.2 ~ 5.0μm, 1.0 ~ 30.0μm, it may be 1.0 ~ 20.0 .mu.m. Arithmetic mean roughness Ra, the maximum height Ry and, if within each said range of ten-point average roughness Rz, irregularities 2b is sufficiently so the anchor effect with respect to the resin member 3. Therefore, the bonding strength between the base material 2 and the resin member 3 is increased.
[0021]
　Also, when controlling the arithmetic mean slope RΔa as defined in JIS B0601 (1994), it was found to be higher bonding strength can be obtained. As a specific example, the arithmetic mean slope RΔa may from 0.17 to 0.50. Higher bonding strength arithmetic mean slope RΔa decreases is reduced. If the arithmetic mean slope RΔa is less than 0.17, it is difficult to obtain a practical bonding strength. Further, it is necessary to control a higher level of processing conditions for forming a more uneven 2b arithmetic mean slope RΔa increases. Therefore, the arithmetic mean slope RΔa is greater than 0.50, there is a fear that productivity is lowered. In particular, when formed by blasting described below such irregularities 2b, it is difficult to process such that the arithmetic mean slope RΔa more than 0.50.
[0022]
　Further, when in addition to the arithmetic mean slope RΔa controls the root mean square slope R? Q, has been found that higher joining strength can be obtained. As a specific example, the root mean square slope RΔq may from 0.27 to 0.60. Higher bonding strength root mean square slope RΔq is reduced is reduced. If the root mean square slope RΔq is less than 0.27, it is difficult to obtain a practical bonding strength. Further, it is necessary to control a higher level processing conditions for root mean square slope RΔq form a larger more uneven 2b. Therefore, if greater than the root mean square slope RΔq is 0.60, there is a fear that productivity is lowered. In particular, when formed by blasting described below such irregularities 2b, it is difficult to process such that the root mean square slope RΔq more than 0.60.
[0023]
　Resin member 3 is partially in a state of entering into the uneven 2b, and is joined to the base material 2. Such structure is formed by injection molding using a mold 20 to be described later.
[0024]
　Compared above, the composite member 1 according to this embodiment, since the micro-order or unevenness of nano-order surface 2a of the base material 2 is a resin member 3 is in direct contact, and if the base material having the unevenness of the millimeter order strong anchor effect Te occurs. Therefore, this composite member has excellent bonding strength.
[0025]

[0029]
　Control unit 19 controls the components of the blasting apparatus 10. Control unit 19 includes a display unit and a processing unit as an example. Processing unit is a general computer having a CPU and a storage unit. Control unit 19 controls the respective feed amounts of the compressed gas feeder 15 for supplying the compressed gas to the storage tank 13 and the pressurizing chamber 14 on the basis of the set injection pressure and injection speed. The control unit 19 is the distance between the workpiece and the nozzle is set, and the scanning condition of the workpiece (speed, feed pitch, number of scans, etc.) based on the control of the injection position of the injection nozzle 12. As a specific example, the control unit 19 controls the position of the injection nozzle 12 by using the pitch (Y-direction) and the feed scanning speed set before the blasting process (X direction). Control unit 19, by moving the processing table 18 for holding a workpiece, to control the position of the injection nozzle 12.
[0030]
　Figure 5 is a cross-sectional view of the injection nozzle 12 of Figure 4. The injection nozzle 12 has an injection tube holder 120 as the main body. Injection tube holder 120 is a cylindrical member having a space for passing the inside injection material and compressed gas. One end of the injection tube holder 120 is injection material introduction port 123, and the other end is an injection material discharge port 122. Inside the injection pipe holder 120 is formed with an inner wall surface which is tapered toward the injection material discharge port 122 from the injection material introduction port 123 side, convergent accelerating portion 121 of conical shape having an inclination angle is formed . The injection material introduction port 123 side of the injection pipe holder 120, injection pipe 124 of cylindrical shape is provided to communicate with. Converging acceleration unit 121 is tapered toward the injection pipe 124 from the middle of the cylindrical portion of the injection tube holder 120. Accordingly, compressed gas stream 115 is formed.
[0031]
　The injection material introduction port 123 of the injection nozzle 12, the connecting tube 17 of the blasting machine 10 is connected. Thus, storage tank 13, the dispensing unit 16 in the pressurizing chamber 14, connecting tube 17, and form a injection material path injection nozzle 12 are sequentially connected.
[0032]
　The blasting machine 10 configured as described above, the supply amount of the compressed gas which is controlled by the control unit 19 is supplied to the storage tank 13 and the pressurizing chamber 14 from the compressed gas supply unit 15.

Thus, a constant and the injection material is injected into the machined surface of the workpiece. Then, the injection position of the machined surface of the workpiece of the injection nozzle 12 is controlled by the control unit 19, the workpiece is blasted.
[0033]
　Furthermore, cutting chips produced in the blasting injected injection material is sucked by the dust collector (not shown). Not shown in path from the processing chamber 11 to a dust collector classifier is arranged, in a reusable injection material and other fines (reuse becomes size that can not be injection material and blasting with resulting cutting chips) It is separated. Reusable injection material is contained in the storage tank 13 and supplied again to the injection nozzle 12. Fines are collected by the dust collector.
[0034]
　It will now be described injection molding. Injection molding, insert molding is used here. In insert molding, mounting the insert in a predetermined mold, by injecting resin is cured by maintaining a predetermined time. Then, remove the residual stress of the resin by heat treatment. Figure 6 is a top view of a mold used in injection molding. Figure 7 is a cross-sectional view of the mold along the line VII-VII of FIG. 6, as shown in FIG. 7, the mold 20 includes a mold body 21 (upper die 21a and lower die 21b). Between the upper die 21a and the lower die 21b, and a space 22 and a space 23 where the resin is injected for mounting an insert (base material 2 in this case). On the upper surface of the upper die 21a, a resin injection port is provided. Resin injection port, sprue 24 communicates with the space 23 through the runner 25 and gate 26. In the space 23, the pressure sensor 27 and temperature sensor 28 is provided, the pressure and temperature of the space 23 is detected.

The parameters, mold temperature, the resin temperature at the time of filling, filling pressure, injection rate, holding time, the pressure during the holding, the heat treatment temperature, etc. heat treatment time. Molded article molded by the mold 20 is a lap joint structure for joining a predetermined area.
[0035]
　Next, a flow of a manufacturing method of the composite member 1. Figure 8 is a flow chart of a method of producing a composite member 1 according to the embodiment. As shown in FIG. 8, first, as the step of preparing (S10), a predetermined injection material is filled into the blasting machine 10. Particle size of the injection material is, for example, 30 ~ 300 [mu] m. The higher the particle size becomes small, the weight is reduced, the inertia force is reduced. Therefore, the particle diameter becomes difficult to form an uneven 2b of a desired shape in the case 30μm smaller. The larger the particle size, because the mass is large, the inertia force increases. Thus, the injection material by colliding with the base material 2 is easily crushed. As a result, (1) the energy of the collision is poor processing efficiency from being distributed in addition to the formation of irregularities 2b (2) is severely wear of the injection material is not economical, problems such occurs. Such a problem becomes remarkable when the particle size exceeds 300 [mu] m.
[0036]
　Control unit 19 of the blasting machine 10, as the step of preparing (S10), obtains the blasting conditions. Control unit 19, the blasting conditions are obtained based on information stored in the operation or the storage unit of the operator. The blasting conditions, injection pressure, injection speed, nozzle distance, scanning conditions of the work (speed, feed pitch, number of scans), and the like. Injection pressure is, for example, 0.5 ~ 2.0 MPa. Higher injection pressure is reduced, the inertial force is lowered. Therefore, the injection pressure becomes difficult to form an uneven 2b of a desired shape in the case 0.5MPa smaller. I see the injection pressure is large, the inertial force is increased. Thus, the injection material by colliding with the base material 2 is easily crushed. As a result, (1) the energy of the collision is poor processing efficiency from being distributed in addition to the formation of irregularities 2b (2) is severely wear of the injection material is not economical, problems such occurs. Such a problem becomes remarkable when the injection pressure exceeds 2.0 MPa. Control unit 19, by managing the blasting conditions, the size and depth of the irregularities 2b of the surface 2a of the base material 2, to precisely control the density and the micro-order or nano-order. Incidentally, the blasting conditions may include a condition that identifies the blasting target area. In this case, it is possible to selective surface treatment.
[0037]
　Next, the blasting machine 10, the blasting process: as (S12 surface treatment step), a series of the following processes. First, the base material 2 to be blasted object is set on the work table 18 in the processing chamber 11. Next, the control unit 19 activates the dust collector (not shown). Dust collector based on the control signal of the control unit 19, a negative pressure state by reducing the internal pressure of the processing chamber 11. Then, the injection nozzle 12, based on the control signal of the control unit 19, the range of injection pressure 0.5 ~ 2.0 MPa, for injecting injection material as a solid-gas two-phase flow of the compressed air. Then, the control unit 19, the processing table 18 is operated to move the base material 2 jet in the solid-gas two-phase flow (Fig. 4, below the injection nozzle). Figure 9 is a conceptual diagram of blasting. As shown in FIG. 9, the injection material is injected from the injection nozzle 12 of the surface 2a of the base material 2 to a part region 2c. Here, the control unit 19, by continuing the operation of the processing table 18, jet actuates so as to draw a predetermined trajectory relative to the base material 2. Figure 10 is a diagram for explaining the scanning of blasting. As shown in FIG. 10, the control unit 19 operates in accordance with the locus L scanning the processing table 18 at a feed pitch P. Thus, the desired micro-order or nano-order irregularities 2b on the surface of the base 2 is formed.
[0038]
　Using injection material of particle size 30 ~ 300 [mu] m, by blasting in a range of injection pressure 0.5 ~ 2.0 MPa, the desired on the surface 2a of the base material 2 micro-order or nano-order irregularities 2b (e.g. , irregularities 2b arithmetic mean slope RΔa and root mean square slope RΔq is controlled to respectively 0.17 to 0.50,0.27 to 0.60) is formed. After stopping the operation of the blasting machine 10, take out the base material 2, blasting is completed.
[0039]
　Then, the molding machine (not shown), as the bonding step (S14), performs shaping using the above-described mold 20. First, the mold 20 is opened mold, blasted base material 2 is attached to the space 22, the mold 20 is closed mold. The generator is a dissolved resin having set the resin temperature is injected from the resin injection port to the interior of the mold 20. Injected resin passes through the sprue 24, runner 25 and gate 26, is filled in the space 23. Generator controls the filling pressure or injection of the resin based on the detection result of the pressure sensor 27. Generator based on the detection result of the temperature sensor 28 is controlled to the mold temperature reaches the set value. Also, generator, based on a detection result of the pressure sensor 27, during the set retention time is controlled such that the pressure becomes the set value. Thereafter, generator, based on the heat treatment temperature and heat treatment time is set, a heat treatment is performed. Thereafter, generation machine, the mold 20 and the mold is opened to take out the composite member 1 base material 2 and the resin member 3 are integrated. When joining step (S14) is completed, it terminates the flowchart shown in FIG.
[0040]
　As described above, in the manufacturing method according to the present embodiment, unevenness 2b micro order or nano order is formed on the surface 2a of the base material 2 to be joined directly to the resin member 3. When the resin member 3 is hardened enters the unevenness 2b micro order or nano order, the strong anchoring effect occurs than in the case of irregularities of the millimeter order. Therefore, the manufacturing method according to the present embodiment, it is possible to manufacture a composite member 1 having a high joint strength.
[0041]
　Further, by blasting, by forming an uneven 2b micro order or nano order on the surface 2a of the base material 2, as compared with other surface treatment techniques for bonding the members, quantitative the surface structure of the junction surface control is possible, it is possible to perform surface treatment cost and in a short time.
[0042]
　For example, other surface treatment methods, chemical etching type and laser processing type are known. Compounds etching type, to form a fine shape on the surface of the metal member by chemical etching, by insert molding, is a technique for joining the metal member and a resin member. This approach, although shorter processing times in that it can batch, wastewater treatment is required because it is a wet process. Moreover, this approach is difficult to quantitatively control a fine shape. Laser processing type, by laser processing to form fine features on the surface of the metal member, by insert molding, is a technique for joining the metal member and a resin member. This approach is a dry process, and, although it is possible to quantitatively control a fine shape, the cost of the laser light source is high, there is a possibility that the processing time becomes long. Compared to these methods, the surface treatment method by blasting, the surface structure of the joint surface is quantitatively controllable, it is possible to realize low cost and short time.
[0043]
　Above, it has been described the present embodiment, the present invention is not limited to the above embodiment, in addition to the present embodiment can be practiced with various modifications within the scope not departing from the gist it is a matter of course.
[0044]
[Base material, variation of the resin member]
　As the base material 2 and the resin member 3 according to the embodiment, although the plate-like member as an example, is not limited to the shape, any shape that can contact with each other it can be adopted. Resin member 3 according to the embodiment has been in contact with the part of the surface of the base material 2, it may be in contact with all the surface of the base 2.
[0045]
Modification of the injection molding]
　Injection molding is not limited to the insert molding, it may be outsert molded.
Example
[0046]
[Base material 2]
　the base material 2, the following materials were used.
　　Matrix A: aluminum plate (JIS (Japanese Industrial Standards): A5052)
　　matrix B: polyimide plate
[0047]
[Blasting process]
　were blasting the surface of the base material 2 using a blasting device 10 described in the embodiment. Injection material, was used by mixing and injection material consisting of aluminum oxide, and the injection material made of glass. Particle size of the abrasives is 40 ~ 250 [mu] m. Blast area density is the percentage of the total area occupied by the dents of the injection material by blasting to the total working area of the (Coverage) is 50% to 100% range of 40 ~ 250 [mu] m particle size of the injection material, injection pressure was subjected to blasting suitably selected from the range of 0.5 ~ 2.0 MPa, and formed Ra on the surface of the base 2, Ry, Rz, RΔa, irregularities 2b which RΔq is controlled.
[0048]
[Bonding process]
　using a mold 20 described in above embodiment, the base material 2 is bonded to the resin member 3. Material of the resin member 3, polybutylene terephthalate resin (PBT: manufactured by Toray Industries, Inc.: 1101G-X54) was used. During filling, mold temperature 140 ° C., the resin temperature is 270 ° C., the filling pressure is 60 MPa, the injection rate 64.2Cm 3 was / s. During the holding, holding pressure 40 MPa, holding time was 8s. In the heat treatment, the heat treatment temperature is 130 ° C., the heat treatment time was 2h.
[0049]
[Evaluation of bonding strength]
　shear strength of the composite member 1 created in the above conditions were evaluated (shear stress). Evaluation device, ISO 4587 as the shear strength that complies with the (1995) can be more accurately measured, using an evaluation device having a structure which suppresses the deflection occurring in the composite member 1 at the time of measurement.
[0050]
　Figure 11 is a schematic cross-sectional view of the evaluation device 30 of the shear strength. As such, the evaluation device 30 shown in FIG. 11 includes a base 31, the base material gripping portion 32 grips the base material 2, and a resin member gripper 33 for gripping the resin member 3. Preform gripper 32 and the resin member gripper 33 is opposed on the base 31.
[0051]
　Preform gripper 32 grips the base material 2 between the gripping surface 32a and the pressing member 32b. Preform gripper 32, its bottom portion is fixed to the fixed portion 31a of the base 31. Resin member gripping portion 33 grips the resin member 3 between the gripping surface 33a and the pressing member 33b. Resin member gripper 33 has wheels 33c at its bottom, it is movable in the direction toward or away from the base material gripping portion 32. Resin member gripper 33 is connected to the ball screw 34a of the motor 34 provided in the base 31, the movement of the direction of access for the base material gripping portion 32 is controlled. By operating the motor 34, the tensile force between the base material 2 and the resin member 3 acts. Tension is detected by the load cell 35 which is provided between the base 31 and the base material gripping portion 32.
[0052]
　Gripping surface 33a of the resin member gripping portion 33, as compared to the gripping surface 32a of the base material gripping portion 32, it is higher by the thickness of the base material 2. Accordingly, since the action of the tensile force shaft and the junction surface of the base material 2 and the resin member 3 are matched, you can apply a shear force to the joint surface. The size of the gripping surface 32a of the base material gripping portion 32 is greater than the base material 2. The entire base material 2 to prevent the occurrence of deflection by supporting with the gripping surfaces 32a, tension of the operating shaft and the bonding surface can keep a matching state. The measurement results are shown in Table 1.
[Table 1]

　Example 1, using the base material A, Ra, Ry, Rz are each 0.2 ~ 5.0μm, 1.0 ~ 30.0μm, so that a range of 1.0 ~ 20.0 .mu.m is an example of controlling the shear stress was 6.4 MPa. Practical shear stress (7 MPa estimated) slightly below, but by controlling the parameters of the unevenness 2b more precisely, the practical shear stress obtained was suggested.

　Examples 2 to 23, using the base material A, which is an example of controlling such RΔa and RΔq is in the range of each 0.17 to 0.50,0.20 to 0.60. Both are significantly higher than the practical shear stress, the resin is well bonded was confirmed.
[0054]
　Example 24, using the base material B as an example in the case of the non-metal base material, was controlled to RΔa and RΔq is in the range of each 0.17 to 0.50,0.20 to 0.60 it is an example. Both are significantly higher than the practical shear stress, the resin base material other than metal is well bonded was confirmed.
Industrial Applicability
[0055]
　By forming the irregularities of micro-order or nano order on the surface of the base, it has been found to be produced a composite member having a high joint strength. This unevenness may also be formed by blasting. Bonding techniques using blasting, the most important three requirements for the surface treatment type dissimilar direct bonding (quantitative control of the surface structure, processing time and processing cost, dry process) satisfies only the. Further, blasting, it is possible to form the unevenness easily, which is advantageous from the viewpoint of environmental and economic. Therefore, bonding techniques using blasting, to increase development of direct bonding technique, greatly expected that encourage industrial progress.
