Explanation
composite materials based on thermoplastic resin. In principle, all thermoplastic plastics can be used as the matrix of composite materials materials, such as polypropylene, polyamide, saturated polyester, polycarbonate, polyphenylene sulfide, polyether ketone, thermoplastic polyimide, polyphenylene oxide, polysulfone, polylctrafluorocthylone, polyvinyl chloride, polystyrene and liquid crystal polymers. Commonly used reinforcements include short cut fibers Continuous fiber or powder free Materials, etc. thermoplastic resin has many unique advantages - such as high toughness, good impact resistance, stable prepreg without storage time limit, short manufacturing cycle, good chemical resistance, low moisture absorption, reprocessing, etc. The melt viscosity of thermoplastic resin like melt is very high, and the impregnation with reinforcement is worse than that with hot solid resin. The suitable molding processes include injection molding, hot m molding, vacuum press molding T_ process, fiber filament winding Roll forming and pultrusion forming, etc. Thermoplastic resin based composite materials have excellent K properties, damage resistance, fatigue resistance, radar wave transmission properties, dielectric transmission properties, etc. The application in the aviation and aerospace fields is becoming increasingly widespread.
