Continuous carbon fiber reinforced polyphenylene sulfide composite material

Abstract

A continuous carbon fiber reinforced polyphenylene sulfide composite material comprises the following substances in parts by weight: 5-65 parts of continuous carbon fibers, 30-95 parts of polyphenylene sulfide resin, 0.3-10 parts of an interface modifier and 0.3-1 part of a processing modifier. According to the prepared composite material, the interface bonding performance between the continuous carbon fibers and the polyphenylene sulfide resin is effectively improved through the carbon fiber treatment process and the interface modifier, the high-strength and heat-resistant continuous carbon fiber / polyphenylene sulfide composite material is prepared, and the application prospects in the industries of spaceflight, military industry, traffic vehicles and sports goods are good.

Description

technical field [0001] The invention belongs to the field of carbon fiber polyphenylene sulfide composite materials, in particular to a continuous carbon fiber reinforced polyphenylene sulfide composite material. Background technique [0002] For carbon fiber reinforced polyphenylene sulfide materials, methods such as modifying polyphenylene sulfide resin or sizing the carbon fiber surface are usually used to enhance the interfacial bonding strength between carbon fiber and polyphenylene sulfide.

Problems solved by technology

[0005] However, the above-mentioned existing method improves the mechanical properties of the CF / polyphenylene sulfide composite material to a certain extent by treating the carbon fiber, but the surface inertia of the carbon fiber is too strong, and the activity of common modifiers reacting with it is very low; at the same time , polyphenylene sulfide is also a weaker polar material with low end group reactivity

Therefore, the reported strength improvement of carbon fiber polyphenylene sulfide reinforced materials is still unsatisfactory, and cannot meet the special requirements for high-strength materials in the military and aerospace fields, and further improvement is needed
