Abstract
A carbon--carbon composite clutch friction material for use with a wet lubricant under severe operating conditions is disclosed, the material comprising a woven carbon fabric mesh (suitably a satin weave mesh) infiltrated with pyrolytic carbon to an unusually high density in the range of at least 1.3 g/cc to about 1.5 g/cc. By infiltrating the woven carbon fabric with carbon to such high density, a wear-resistant friction material is provided that still retains enough surface texture for lubricant transport.
