Abstract
The present invention relates to a fibrous base material comprising a primary layer of less fibrillated aramid fibers, synthetic graphite and at least one filler material, and a secondary layer of carbon particles on at least one surface of the fibrous base material for use in a non-asbestos friction material. In certain embodiments, the fibrous base material is impregnated with a phenolic or phenolic-based resin material, including, for example, a mixture of a phenolic resin and a silicone resin to form a friction material having good 'break-in' and durability characteristics.
