▎ 摘 要
NOVELTY - A brake friction material contains (in weight%) organic aramid fiber (3-7), inorganic fiber (10-30), thermosetting resin (10-30), filler (10-35), metal fiber (10-40) and graphene (10-20). The filler contains barium compound. USE - Brake friction material used for brake pad and brake lining of vehicles (both claimed) e.g. car. ADVANTAGE - The brake friction material has excellent durability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of brake friction material.
