Abstract
The present invention relates to a friction material comprising a silicone resin, a phenolic resin, and, in certain embodiments, silicon nitride particles, incorporated into an aqueous paper formulation which is then formed into a friction material. The friction material is prepared by mixing the silicone resin, the phenolic resin (and, in certain embodiments, silicon nitride particles) into a raw paper formulation, forming a porous friction material, and heating the friction material to cure the phenolic resin and silicone resin.
