FRICTION MATERIAL

Abstract:

A friction material includes a friction-generating layer, a core layer, and a third 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 third layer is adjacent to the core layer such that the core layer is disposed between the friction-generating and third layers. The third layer presents a multi-functional surface facing opposite the friction-generating surface of the friction-generating layer. The third layer includes a multi-functional material. The multi-functional material includes: multi-functional; and/or woven 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 third layer.
