Abstract
A slide member having a substrate and a sliding layer formed on at least a sliding surface side of the substrate. The sliding layer comprises a resin composition comprising a polyamide-imide resin and an organically modified layered clay mineral dispersed uniformly in the polyamide-imide resin, and a solid lubricant held by the resin composition. The resin composition has an average linear expansion coefficient of between 3.12 and 5×10-5/° C. in the range from 100 to 200 ° C. The process for producing a slide member comprises coating at least the sliding surface side of a mixture of a resin solution comprising a polyamide-imide resin and a solvent for dissolving the polyamide-imide resin, solid lubricant powder, and an organically modified layered clay mineral; and subsequently removing the solvent of the coating composition.
