Abstract
Low density friction products composed of non-asbestos reinforcing fibers embedded in a matrix of binder material, optionally including friction and wear modifiers, are described in which the actual density of the product is less than 72% of the theoretical density. Clutch facings of this density exhibit improved wear characteristics, lower inertia and increased burst strength.
