<p>Low abrasion, heat resistant, high strength friction material with a high resistance 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 brake blocks for disc and drum brake applications on heavy duty trucks and the like. This invention is distinguishable from others by reason of the use of spun blast furnace slag fibers rather than the asbestos fibers which have generally been used in the prior art brake block materials.</p> |
