Title: FRICTION MATERIAL AND RESIN COMPOSITION FOR FRICTION MATERIAL
Abstract:
Disclosed is a friction material characterized by using a resin composition for friction materials which contains, as a binder, an aromatic imide oligomer having an addition-reactive group at an end. Also disclosed is a resin composition for friction materials, which is characterized by containing an aromatic imide oligomer powder having an addition-reactive group at an end, at least one fiber selected from the group consisting of carbon fibers, aramid fibers, glass fibers, ceramic fibers and metal fibers, and an inorganic filler. When compared with a friction material using a phenol resin as a binder, the friction material of the present invention extremely excels in heat resistance and mechanical characteristics of the binder itself, while having good formability.
