Abstract
A friction bearing composite material comprises a metal base layer, a porous support layer applied thereto, and a low friction layer made from PTFE forming a bearing surface for a bearing partner. The low friction material forming the sliding surface also fills the pores in the support layer and comprises at least 60 vol. % PTFE and 10-25 vol. % zinc sulphide. In order to achieve a high wear resistance with a low coefficient of friction, the low friction material further comprises 1.5-3.5 vol. % carbon fibers and 1-7 vol. % PFA.
