Problems solved by technology

However, graphene and MoS2 with enhanced wear resistance are still expensive and difficult to mass-produce, especially for the recovery and utilization of recycled carbon fibers
[0005] In addition, there are few reports on the application of recycled carbon fiber to the high wear-resistant polyphenylene sulfide composite system.

Abstract

The invention relates to a high-wear-resistance polyphenylene sulfide/regenerated carbon fiber composite material and a preparation method thereof. The high-wear-resistance polyphenylene sulfide/regenerated carbon fiber composite material comprises the following components in parts by mass: 50-100 parts of polyphenylene sulfide (PPS); 5 to 40 parts of polytetrafluoroethylene (PTFE); 5-45 parts ofregenerated carbon fibers; and 0.5 to 5 parts of a nanoparticle filler. The preparation method comprises the following steps of: weighing 50-100 parts of the PPS, 5-40 parts of the PTFE and 0.5-2 parts of the nanoparticle filler according to proportions and placing the components in a high-speed mixer, and uniformly mixing the components; and adding the completely prepared raw materials into a main feeding port and an auxiliary feeding port of a double-screw extruder, and carrying out melt blending, extrusion, water drawing, bracing and dicing so as to obtain the polyphenylene sulfide/regenerated carbon fiber composite material. Compared with the prior art, the polyphenylene sulfide/regenerated carbon fiber composite material has the characteristics of high temperature resistance, frictionresistance and excellent mechanical properties. And meanwhile, the recycling of the carbon fibers also has the advantages of energy conservation, environmental protection and low cost.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, and in particular relates to a high wear-resistant polyphenylene sulfide / regenerated carbon fiber composite material and a preparation method thereof. Background technique [0002] At present, the recycling technology of carbon fiber resin-based composite materials is becoming more and more mature, and the utilization of recycled carbon fibers will definitely become the future development direction. Carbon fiber-reinforced high-performance resin-based composite materials have high strength, light weight, and impact resistance. They are typical structural and functional advanced composite materials. They are not only widely used in the aerospace field, but also become good friction materials due to the unique advantages of polymers. Widely used in many important parts subject to friction. Moreover, many parts subject to high friction are in high-temperature environments, so the preparat...
