Abstract: A heat resistant low abrasion high strength friction material with a high resistance to wear is described as containing asbestos fibers, phenolic resin, spun blast furnace slag fibers, rubber particles, a filler and ferrous or non-ferrous particles. The friction material finds particular use in the formation of brake blocks, drum brake lining and disc pads for vehicle braking systems and the like.
Abstract: Low abrasion, heat resistant, high strength friction material with a high resistance to wear is described as containing phenolic resin, an organic modifier, processed mineral fibers and a filler. Rubber, either natural or synthetic, graphite, a metallic oxide, a color pigment, and factice may also be present. The material finds particular use in friction materials for brake blocks, drum brake linings and disc pads for vehicle braking systems and the like.
