Title of the invention: -
3D printed PLA sheets embedded bio-composite manufacturing method thereof
Field of the invention: -
The present invention relates to the field of materials and particular relates to field of bio-composite manufacturing with 3D printed Poly Lactic Acid (PLA) sheets and natural fibre.
Prior art to the invention: -
A patent document with application number "CN101519574A", titled with "Preparation method of thermosetting type composite adhesive", describes, "The invention provides a preparation method of a thermosetting type composite adhesive, which comprises the steps of preparing polyester polyol and preparing thermosetting composite adhesive, wherein the polyester polyol is prepared through primary esterification, secondary esterification and condensation polymerization; dimethyl terephthalate (DMT) and diglycol are added to a polyester synthesis kettle to carry out the primary esterification; dimeric dibasic acid, m-phthalic acid, nonane diacid and 1,3-butanediol are added to the polyester synthesis kettle in which the primary esterification reaction is finished to carry out the secondary esterification; low vacuumizing, high vacuumizing and long vacuumizing are sequentially carried out for the polyester synthesis kettle in which the secondary esterification is finished, and the polycondensate generated after the condensation polymerization is the polyester polyol; the thermosetting composite adhesive is prepared by mixing evenly the prepared polyester polyol, enclosed type isocyanate tripolymer, a component solvent, titanic acid ester chelon, tackifying resin and plasticizer. The thermosetting type composite adhesive prepared by the method has excellent bonding intensity when used for bonding PVC and an armor plate without chemical treatment for the surface."
wherein, the present invention provides the method of manufacturing poly lactic acid sheet embedded bio composite material.
Objects of the invention: -
The primary object of the present invention is to provide the bio-composite with increased strength. The secondary object of the present invention is to provide new applications using the biocompatible material.
Summary of the invention: -
The manufacturing of composite material generally using the core fibre, reinforcement and semi-solid state of binder to make the complete bondage between all these materials. In present invention is focusing on the using all these materials in solid state including the binder to manufacture composites. In this way of manufacturing of composite aid in even distribution of binder over the core fibre which in turn increase the strength of composite material.

Detailed description: -
The following specification particularly describes the invention and the manner in which it is to be performed.
The manufacturing of composite material generally using the core fibre, reinforcement and semi-solid state of binder to make the complete bondage between all these materials. In present invention is focusing on the using all these materials in solid state including the binder to manufacture composites. In this way of manufacturing of composite aid in even distribution of binder over the core fibre which in turn increase the strength of composite material. The binding is considered to be effective in terms of increasing the strength of the composite. The solid binder while applying the over the core fibre along with distributed reinforcement materials which spread evenly and bind with the core material effectively which is most required parameter in composite material. The core material might be any bio-natural fibres like jute, hemp, sisal, banana and any other. The reinforcement materials of any bio-materials and or non-biomaterials.
The embodiment comprises of a core fibre (1) is embedded with a reinforcement (3) and to bind these two materials a PLA sheet (2) which are 3D printed placed in plurality at various stage on top, bottom as well as in middle then the hot is applied thorough compression moulding machine around 200 degree Celsius.
The example herein is taken comprises of jute woven of 2 layers without any reinforcement. The PLA 3D printed sheet is taken as 3 in numbers placed top, middle and bottom and applied around 200-degree Celsius. The PLA is distributed evenly the strength is measured and it shown improved. It is not restricted the material mentioned in the example.

Claims: -
1) We claim,
A 3D printed PLA sheets embedded bio-composite manufacturing method thereof: comprises of,
A core fibre (1);
A PLA sheet (2); and
A reinforcement (3);
wherein, the core fibre (1) is embedded with the reinforcement (3) and to bind these two materials the PLA sheet (2) which are 3D printed placed in plurality at various stage on top, bottom as well as in middle then the hot is applied thorough compression moulding machine around 200 degree Celsius
2) The computers with hybrid phase change material as claimed in claim 1, wherein, the said
method used to produce the composite which spreads the binder evenly over the solid core
