Abstract:

This article summarized the mainstream impregnation and processing technologies of continuous?fiber?reinforced thermoplastic prepregs at home and abroad, which included hot melting, solution impregnation, film stacking, blending, powder impregnation, and in?situ polymerization. The advantages and disadvantages of various technologies were compared in terms of raw materials, equipment, and processing procedures. The design and applications of thermoplastic prepreg forming molds were also discussed. The development status of thermoplastic prepregs was introduced. The preparation methods for the lightweight and diversified thermoplastic prepreg impregnation technologies, including three?dimensional continuous weaving technology, were also discussed. Finally, the development direction of preparation technology for thermoplastic prepregs in the future was analyzed and prospected.

Key words: prepreg, thermoplastic resin, composite material, preparation process, fiber impregnation
