ABSTRACT:
An improved friction material composite is disclosed that contains a fibrous reinforcing constituent, various friction imparting and controlling additives, and a thermosetting resin mixture in which mixture is contained pitch, a polyimide resin, and optionally a phenolic resin. Pitch-polyimide mixtures can be formulated to provide unusually high temperature resistance and strength and the pitch-polyimide-phenolic resin mixtures formulated to provide like properties at moderate cost.
