Description of the invention (1) Field of the invention The present invention relates to a method for preparing a thermoplastic composite material with a textile texture, and more particularly to a method for preparing a thermoplastic composite material with a textile texture by stamping. BACKGROUND OF THE INVENTION As the world's production process simplifies the superior physical properties of composite materials. At present, the thermal industry and exerciser methods mostly use flat plastics to form tough and elastic thermoplastic high and thermosetting plastic composite materials. Thermoplastic composite materials produced by the thermoplastic method of other materials have excellent physical properties and product trends, and can meet the requirements of solid polymer materials in various fields, transportation layers, thermocompression composite materials, and molecular composite materials. The purpose of hot pressing of admixtures based on material-based compression molding is to provide composite molded products of composite materials. In addition to points, they tend to be light, thin, short, and small, as well as the products of polymer composite materials themselves The purpose of weight reduction makes high scores more and more common. Composite materials have been widely used in various fields such as the aerospace industry, and the processing side is used for molding. The use of fiber fabrics to enhance its application can further improve the product materials. Due to the differences in material properties, processing methods, and molding processing, a method of forming products using punching products has the special characteristics of compounding the thermoplastic properties of the materials. For this reason, there is a great deal of non-compression molding technology for working conditions and operations. By the present invention, the fibrous fabric, the plastic substrate of the fibrous woven material product, the thermoplastic operation procedure is the same.
