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.

Friction material for clutch

A friction engagement element has a friction member including resin, and a metal member having a sliding surface slidable on the friction member. The friction member has an aged layer at an outermost layer of the friction member, and a hardened layer in abutment with an inner side of the aged layer in a thickness direction of the friction member. The sliding surface of the metal member has a plurality of recesses, and a transferred film of the aged layer of the friction member transferred and adhered to insides of the plurality of recesses through sliding between the friction member and the metal member.
