Abstract
A friction material and process of forming a friction material embodies a slurry of aramid, acrylic and carbon fibers, together with kaolin clay and aluminum oxide used as fillers in a phenolic resin binder. The matrix formed by the fibers entraps a relatively large quantity of carbon particles. The carbon particles comprise more than forty or fifty percent of the weight of the material. During the process of formation, the slurry is de-watered to reduce moisture content to the order of two percent before the resin binder is cured under heat and pressure.
