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.
