The invention discloses a composite material for a center plate wearing plate, the center plate wearing plate and a preparation method of the center plate wearing plate. The composite material comprises the following raw material components in parts by weight: 100 parts of caprolactam, 0.03-0.1 part of a catalyst, 0.03-0.1 part of a promoter, 10-30 parts of a lubricant and 2-10 parts of a heat conducting agent, wherein the lubricant comprises polytetrafluoroethylene fibers and/or ultra-high molecular weight polyethylene fibers; the center plate wearing plate comprises a base plate and a functional layer, the base plate comprises a base plate body, and the functional layer comprises the composite material; the preparation method comprises the following steps: treating the lubricant, adding caprolactam for melting, adding the catalyst, the lubricant, the heat conducting agent and the cocatalyst for heating, molding, curing and demolding. The performance of the center plate wearing plate is comprehensively improved, the friction coefficient is lower, abrasion is smaller, the service life is longer, the bearing performance and the abrasion rate are better, and the center plate wearing plate is more suitable for a metro vehicle bogie system.
