Forming method for thermoplastic composite

Abstract

The invention relates to a forming method for a thermoplastic composite. The forming method comprises the steps of firstly cutting a thermoplastic film and a cloth material into predetermined shapes respectively, wherein the thermoplastic film has an adhering layer and a surface layer; the surface layer has a higher melting point than that of the adhering layer; then laminating the thermoplastic film and the cloth material on a carrier to make the adhering layer of the thermoplastic film face to the cloth material; then heating to melt the adhering layer and soften the surface layer; vacuumizing from the carrier so as to absorb the thermoplastic film and the cloth material downward and press from top to bottom by using a press-fit member, so as to permeate the adhering layer of the thermoplastic film into the cloth material to form tight adhesion. When the carrier is provided with a plurality of convex-concave patterns and the surface layer of the thermoplastic film faces to the top surface of the carrier, clear stereoscopic patterns corresponding to the convex-concave patterns can be formed on the surface layer; and the cloth material and the thermoplastic film can be combined after being cut into required shapes, so that the thermoplastic composite of the thermoplastic film and the cloth material with different shape combinations can be manufactured.

Description

technical field [0001] The present invention relates to the technical field of a thermoplastic composite material manufacturing method, especially to a thermoplastic composite material that can combine the thermoplastic film and the cloth more closely, can form clearer three-dimensional lines on the surface of the thermoplastic film, and can make the thermoplastic composite material It is a molding method of thermoplastic composite materials with many functions such as changes in the structure. Background technique [0002] A conventional molding method for thermoplastic composites, as shown in the early application of the Chinese Taiwan Publication No. I269703 patent, which winds a release mold layer on a guide wheel so that the release interface with a concave-convex pattern is located on the outside. Then use an extruder to vertically flow the thermoplastic material on the release interface of the release mold layer above the guide wheel, and then make a base cloth wrap a...

AI Technical Summary

Problems solved by technology

However, simply relying on the hot-pressing method of the upper and lower molds to heat-press the cloth material and the thermoplastic film together, the combination effect is not good, and the three-dimensional lines that can be produced by using the concave-convex lines on the moulds will also be damaged. less clear

In addition, it will also produce the phenomenon of wind, which will make the reproducibility of the lines poor and the lines will be less clear.

[0004] The conventional molding method of combining thermoplastic film and cloth to form a thermoplastic composite has the problems of poor bonding between thermoplastic film and cloth, unclear lines formed on the thermoplastic film, and little structural change of the thermoplastic composite.
