Abstract
A clutch friction material includes a base material containing a rubber material and a thermosetting resin. The clutch friction material also includes an intermediate layer disposed on the base material. The intermediate layer includes either a glassy carbon structure or a graphite structure formed as a result of thermal curing of the thermosetting resin contained in the base material. In addition, the clutch friction material includes an outermost surface layer disposed on the intermediate layer. The outermost surface layer contains a pyrolysate produced as a result of pyrolysis of rubber and resin components contained in the base material.
