Disclosed are a graphene/carbon fiber enhanced nylon composite wear-resistant material and a preparation method and application thereof. The material includes a nylon resin, carbon fibers, graphene/nylon 6 master batch, an organic lubricant, an inorganic solid lubricant, a coupling agent and an anti-oxidant. The method comprises: (1) coupling the inorganic solid lubricant with the coupling agent to obtain a coupled inorganic solid lubricant; (2) mixing graphene/nylon 6 master batch, the organic lubricant, the coupled inorganic solid lubricant and the anti-oxidant; and (3) sending the nylon resin and a mixing auxiliary agent to an extruder, adding carbon fibers, performing mixing extrusion, and performing strap stretching, cooling, drying, and grain-sized dicing to obtain the material. The material is used for lubricating bearings and joint bearings of automobiles, and transmission gears of textile, food and packaging machinery or joint bearings of robots. The material is high in strength, good in thermal conductivity, self-lubrication, and wear resistance, and is long in service life. The method is simple and is suitable for industrial production.
