Description:A COMPOSITE MATERIAL FOR A VEHICLE
FIELD OF THE INVENTION
[0001]
The present subject matter is related, in general to a composite material for a plurality of vehicular parts.
BACKGROUND OF THE INVENTION 5
[0002]
Typically, a vehicle comprises plurality of vehicle panel assemblies which covers a plurality of vehicle components which are disposed inside the vehicle. Since, the vehicle panels protects the vehicle components, therefore it is important to ensure optimum tensile strength and structural strength of the vehicle panels. Therefore, usually, the vehicle panels are made of polymers such as plastics. 10 Though plastics are lower density materials than metals, they contribute to significantly to the overall weight of the vehicle. An increased weight of a vehicle can have detrimental effects on its overall riding performance. Firstly, the increased weight adds to the stress on an engine, leading to increased fuel consumption and reduced fuel efficiency. Additionally, heavier vehicles typically exhibit poorer 15 acceleration and deceleration, resulting in sluggish manoeuvrability and compromised responsiveness. Besides braking distances may also be extended, potentially compromising safety of the rider. The increased weight can strain the suspension system, causing discomfort for passengers and reducing overall ride quality. 20
[0003]
Moreover, in traditional manufacturing processes involving the injection moulding of a plurality of vehicle panel assemblies made of polymers, a significant challenge arises during the cooling phase of the injection moulding process. As the molten polymer is injected into the mould and begins to cool, it is prone to experiencing warping or distortion. This distortion is a consequence of non-uniform 25 cooling rates across the polymer material. Various factors contribute to this phenomenon, including variations in thickness and geometry within the panel assembly. Therefore, in view of the above it is important to reduce weight of the vehicle while ensuring optimum structural integrity, tensile strength of the plurality
3
of vehicle panels
and minimize or eliminate the warping and distortion issues associated with polymer injection moulding, thus contributing to the production of high-quality and structurally sound vehicle components.
[0004]
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of 5 described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.
SUMMARY
[0005]
As per an embodiment of the present invention a composite material for a vehicle comprises a base material, and a foaming material.

[0006]
As per yet another aspect of the present invention, the base material is Polypropylene material; and the foaming material is at least one of azodicarbonamide or citrate mixture. 15
[0007]
As per yet another aspect of the present invention, the vehicle comprises a floorboard, plurality of vehicle panel assembly, wherein the floorboard vehicle panel assembly are made of the composite material.
[0008]

[00016]
An objective of the present invention is to provide a composite material for a vehicle, which can be used for manufacturing of plurality of vehicle panels, such that the overall weight of the vehicle is reduced without compromising on structural and tensile strength of the plurality of vehicle panels. Thereby the present invention enables to improve fuel efficiency, improved manoeuvrability, enhanced 5 responsiveness of the vehicle.
[00017]
The aforesaid and other advantages of the present subject matter would be described in greater detail in conjunction with the figures & embodiment in the following description.
[00018]
Figure 1 illustrates a side view of a vehicle (100) as per an embodiment of 10 the present invention. The vehicle (100) comprises plurality of vehicle panel assemblies (106). The plurality of vehicle panel assemblies (106) includes a front panel assembly comprising a front panel member, and a rear front panel member (102). The vehicle (100) further comprises a pair of side panel members (106a) which extends towards side portion of the vehicle (100), when the vehicle (100) is 15 viewed in side view. The pair of side panel members includes a left side panel on the left side of the vehicle, and a right-side panel on the right side of the vehicle (100). The vehicle (100) also includes a floorboard (104), which supports the feet of the rider. Traditionally, the plurality of vehicle panel assemblies (106) and the floorboard (104) are made of polymers with additive or without additive. For 20 example, conventionally, the plurality of vehicle (100) panel assemblies and the floorboard (104) are made of polymers with glass additive or talcum additive, or pure polymers such as plastic.
[00019]
Figure 2-4 illustrates a scanned image of a cut section portion of a portion (202) of a vehicle (100) as per an embodiment of the present invention. The 25 floorboard (104) and the plurality of vehicle panel assemblies (106) are made of a composite material. The composite material for the vehicle (100) comprises a base material, and a foaming material. More particularly, the base material is Polypropylene, and the foaming material is at least one of azodicarbonamide or citrate mixture. As per the strength requirement of the part of the vehicle, the 30
6
proportion of the foaming material
in the base material for making the composite material is determined. For example, the proportion of the foaming material in the composite material for a floorboard of the vehicle is relatively less than the amount of foaming material required for vehicle panel member as the strength of the floorboard should be more as compared to the vehicle panel members. Based on 5 the geometrical dimensions of the vehicle (100) part, the foaming material is mixed with the Polypropylene at a pre-defined proportion. The predefined proportion ranges from of the 0.1-5% of the composite material.
[00020]
As per an embodiment of the present invention, in an injection moulding, the pallets of the Polypropylene are added. At a predefined temperature, the 10 predefined proportion range of the at least one of azodicarbonamide or citrate mixture is added to the injection moulding. At the predefined temperature, the at least one of azodicarbonamide or citrate mixture undergoes thermal decomposition which produces nitrogen, carbon monoxide, carbon dioxide, and ammonia gases. This process takes place within the closed chamber of the injection moulding 15 apparatus. Unlike open processes where the gases would dissipate, the closed system of injection moulding traps these gases within the polymer matrix. As a consequence, the gases become entrapped as bubbles, resulting in the formation of a foamed article during the moulding process. After the composite material is adequately shaped and moulded, and the injection moulding apparatus is opened, 20 the trapped gases are allowed to escape into the surrounding air. This release creates plurality of cavities (402) within the polymer material, contributing to the foamed structure of the final product. Importantly, a surface portion i.e., the top surface of the plurality of the vehicle (100) components are solid, while the inner portion, as viewed from cut section view are porous or comprises plurality of cavities (402) 25 within the polymer material. As per an embodiment, the predefined temperature ranges from 100 degrees Celsius to 300 degrees Celsius. In an exemplary embodiment, the predefined temperature is 200 degree Celsius. Furthermore, the composite material can be used for making vehicle panel members, a tail lamp cover, a floorboard, a handlebar cover, vehicle fenders or any other external parts 30 of the vehicle. Further, as per yet another aspect of the present invention, the
7
Element Mass Percentage of the composite material is Carbon 20%; Hydrogen
3.5%; Nitrogen 48%; Oxygen27%; and Others 1.5%.
[00021]
As per an embodiment of the present invention, the chemical composition of the composite material is provided below:
[00022]
Advantageously, the plurality of cavities (402) within the polymer material 5 ensures to reduce the weight of the vehicle (100), thereby ensuring optimum effect on it overall riding performance. Importantly, the reduced weight of the vehicle (100) does not add to the stress on the engine of the vehicle (100) . Thus, the present invention provides increased fuel efficiency, enhanced acceleration, and deceleration, resulting in easy manoeuvrability and improved responsiveness. Thus, 10 the overall riding experience of the vehicle (100) is increased.
