FIBROUS BASE MATERIAL FOR USE IN A NON-ASBESTOS, NON-METALLIC FRICTION MATERIAL, NON-ASBESTOS FRICTION MATERIAL, NON-ASBESTOS, NON-METALLIC FRICTION MATERIAL, AND PROCESS FOR PRODUCING A NON-ASBESTOS, NON-METALLIC FRICTION MATERIAL

摘要

The present invention relates to a fibrous base material for use in a non-asbestos, non-metallic friction material comprising less fibrillated aramid fibers, carbon particles, cotton fibers, carbon fibers and at least one filler material, and the non-asbestos, non-metallic friction material produced therefrom. In certain embodiments, the fibrous base material is impregnated with a phenolic or phenolic-base resin material, including, for example, a mixture of a phenolic resin and a silicone resin.
