Abstract

The invention relates to a method for manufacturing light, electrically-conductive and wear-resistant materials. The method comprises the steps of mechanically superposing and crosswise winding carbonfiber cloths made of metallic-nanoparticle-modified graphene or short fibers made of the same and graphene-modified resin to form a three-dimensional solid structure, allowing the three-dimensional solid structure to be a profile by virtue of hot pressing, using nitrogen gas or helium gas for protection under vacuum conditions and carrying out low-temperature and high-temperature carbonization and high-temperature graphitization. The light, electrically-conductive and wear-resistant materials manufactured according to the method have the characteristics of simple process, light weight, stablesize, high self-lubricating-performance and wear resistance, high strength, corrosion resistance, high heat conductance and high electrical conductance. The light, electrically-conductive and wear-resistant materials can also be used for manufacturing various types and shapes of electrically-conductive and wear-resistant parts such as slide plates of pantographs, self-lubricating and wear-resistant seals, high-heat-conductance devices and the like.

Description

technical field [0001] The present invention relates to a method for making a lightweight conductive wear-resistant material for use in composite materials. Background technique [0002] At present, the electrified locomotives running in China have a speed of 200 to 450 kilometers per hour. The electrification and high-speed of railways have become the development trend of railway transportation in the world. Pantograph slides and catenary wires are the core components of high-speed railways. The current-carrying friction and wear between them is the key to the normal operation of the pantograph-catenary system, which will directly affect the power supply of electric locomotives and the running speed of locomotives. And railway operating costs, and even endanger traffic safety. Therefore, the research on the friction and wear properties of the slide plate and the wire has been a topic that has attracted much attention for a long time. [0003] The current-carrying friction...
