Abstract

A plain bearing material includes a matrix of thermoplastic polymer which contains as inclusions additives improving antifriction properties. In the matrix are contained as additives PTFE and chalk, both PTFE and chalk being in the form of a powder. A composite multilayer material with such a plain bearing material includes a metallic backing on which a rough base is sintered or sprayed on. On this rough base is deposited the bearing metal material with a matrix material in which are included the additives.
