Abstract
A high carbon friction material for use as a friction lining in a brake or clutch. The friction material consists of a combination of fibers selected from a group including glass, asbestos or other mineral fibers, metal powders, friction modifiers and carbon or graphite particles retained in a matrix created by a thermoset phenolic resin to establish a friction lining. The selected fibers and carbon or graphite particles in the friction material jointly combine to establish a substantially uniform wear rate and coefficient of friction up to 500.degree. C. when the friction lining engages a corresponding mating surface.
