  • Patent number: 5083650
    Abstract: A friction member which is suitable for use as a friction facing member in a transmission is provided. the friction member includes a uniform density heat resistant paper, a first layer of thermoset polymeric binder coated over and at least partially impregnated into one major surface of the paper, granular carbon friction particles uniformly distributed over and partially imbedded in the exposed surface of the first layer and a second layer of thermoset binder over the first layer and partially imbedded granular friction particles which coats without obscuring the granular friction particles.

  • Patent number: 4639392
    Abstract: A clutch plate member for operating in a fluid medium to transmit torque to a metal mating surface situated on an opposing clutch plate member in a wide range of slip speeds. The clutch plate member is constructed of a friction facing layer consisting of thermoset resin bonded carbon particles bonded to a compliant carrier sheet which is in turn bonded to a metal support plate. The compliant carrier sheet improves the conformability of the friction facing layer to the metal mating surface resulting in a reduction in the maximum operating temperature of the friction facing layer.
