  • Resin mold clutch facing
    Patent number: 5114769
    Abstract: Disclosed is a resin mold clutch facing integrally heat molded out of a resin mold base member and a reinforcement member. The resin mold base member comprises a matrix composed of a glass fiber and an aromatic polyamide fiber, an inorganic filler, a solid lubricant, and a resin. The reinforcement member comprises a matrix composed of a glass strand or yarn and at least one strand or yarn selected from a group of rayon and an aromatic polyamide strand or yarn and a binder adhered to said matrix, and is shaped in a spirally wound configuration. Thus the weight of the resin mold clutch facing has been reduced, and its friction and anti-wear properties have been improved.

  • Friction material composition for brake lining
    Patent number: 4785029
    Abstract: A molded resin friction material composition for automobiles or the like. This composition contains as base fibers chopped glass fibers and pulped polyamide fibers in a given compounding ratio. This composition enables to produce brake lining having a high friction coefficient, a low wear ratio, and an improved fade. The fade can be further improved by adding cryolite powder and zirconium oxide powder to the composition.
