Abstract

The invention relates to the technical field of novel high-performance carbon fiber composite materials and provides a carbon fiber reinforced polyphenylene sulfide composite material and a preparation method thereof. The carbon fiber reinforced polyphenylene sulfide composite material is prepared from a mixed material through mixing, wherein the mixed material comprises components in percentage by mass as follows: 50%-70% of polyphenylene sulfide, 20%-35% of carbon fibers, 5%-10% of soluble polytetrafluoroethylene, 2%-5% of polysiloxane and 1%-2% of an antioxidant. According to the carbon fiber reinforced polyphenylene sulfide composite material and the preparation method thereof, the mixed material comprises polyphenylene sulfide, the carbon fibers, soluble polytetrafluoroethylene, polysiloxane and the antioxidant, and the carbon fiber reinforced polyphenylene sulfide composite material is obtained through mixing of the mixed material. The components are matched with one another and are combined, and the toughness and the heat resistance of the polyphenylene sulfide composite material can be improved; a result indicates that the heat resistance temperature of the carbon fiber reinforced polyphenylene sulfide composite material is high, and the toughness is better than before.

Description

technical field [0001] The invention relates to the technical field of carbon fiber composite materials, in particular to a carbon fiber / reinforced polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%. It is made of a fiber polymer whose decomposition temperature is lower than the melting temperature, and is made by solid-phase pyrolysis above a thousand degrees. The types of carbon fibers include: polyacrylonitrile-based carbon fibers (PAN-based carbon fibers), pitch-based carbon fibers, and viscose-based carbon fibers. Since the 1960s, carbon fiber has rapidly developed into a new type of reinforced material, which has the advantages of high strength, light weight, fatigue resistance, excellent performance, large modulus and low thermal expansion coefficient, and is widely used in the field of composite materials. However, the c...
