FRICTION MATERIAL

Abstract:

A friction material includes a friction-generating layer, a core layer, and a base layer. The friction-generating layer presents a friction-generating surface and includes a friction-generating material. The friction-generating material includes friction-adjusting particles. The core layer is adjacent to the friction-generating layer and includes a core material. The core material includes core fibers. The base layer is adjacent to the core layer such that the core layer is disposed between the friction-generating and base layers. The base layer presents a bonding surface facing opposite the friction-generating surface of the friction-generating layer. The base layer includes a fibrous material. The fibrous material includes base fibers chosen from aramid fibers, carbon fibers, cellulose fibers, acrylic fibers, polyvinyl alcohol fibers, glass fibers, mineral fibers, and combinations thereof. A resin is present in at least one of the friction-generating layer, the core layer, and the base layer.
