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. [0003] Document "Improvement of Mechanical Properties of Polyphenylene Sulfide / Carbon Fiber Composites Modified by Aminated Reinforcement", HRui, K Zhang, ...Materials Science Forum (2015), using different mass fractions of ammoniated polyphenylene sulfide to modify carbon fiber reinforced polyphenylene sulfide composites, containing 7wt% PPS-NH2 The tensile strength of the PPS / CF composite was increased by 12.5%. [0004] Plastic Industry, 2013 (01), P100, reported that the intr...
