  • Process for producing dry clutch facing
    Patent number: 6471807
    Abstract: A dry clutch facing includes a facing element which is comprised of a roving wound into a volute shape and impregnated with a rubber, a thermosetting resin and a friction improving agent. The dry clutch facing also includes a reinforcing element which includes a matrix formed of a thermosetting resin and a reinforcing fiber dispersed in the matrix. The reinforcing element is bonded to the back of the facing element and placed in contact with a cushion spring. A peculiar distortion caused by the volute shape winding and a wearing on the back side by the cushion spring can be inhibited largely.
