Description

Technical field [0001] The invention belongs to the technical field of polymer material modification, and specifically relates to a wear-resistant low-fiber glass fiber reinforced polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a special engineering plastic with excellent comprehensive properties. It has the characteristics of high strength, good chemical resistance, flame retardancy, and creep resistance. It is widely used in automobiles, electronic and electrical, aerospace and chemical industries. field. However, polyphenylene sulfide also has shortcomings such as high brittleness and low toughness, which restrict its further application and development. Although PPS is reinforced with glass fiber, its mechanical properties can be significantly improved, but the surface of the product is rough, the gloss is poor, and there are many floating fibers, which can not meet the appearance require...
