Friction material

Abstract:

A friction material presents a friction generating surface and a bonding surface facing opposite the friction generating surface. The friction material includes an organopolysiloxane resin, a plurality of fibers, and a plurality of friction particles. The organopolysiloxane resin includes siloxy units independently represented by the following formula: (R.sub.1SiO.sub.3/2) and/or (R.sub.2SiO.sub.2/2); wherein each R.sub.1 and R.sub.2 is independently selected from a monovalent hydrocarbon group having from 1 to 20 carbon atoms.
