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.
