  • Patent number: 5830566
    Abstract: A molded friction material for a damper is disclosed, which contains, as a part of a friction regulating material, porous fibrous particulates having an average particle size of 0.5 to 2 mm and a bulk density of 0.1 to 0.2 g/cm.sup.3 and comprising finely divided ceramic fibers or porous fibrous particulates having an average particle size of 0.1 to 5 mm and a bulk density of 0.2 to 2.0 g/cm.sup.3 and comprising finely divided ceramic fibers, a filler, and a binder. The friction material exhibits excellent performance basically required of a friction material, such as mechanical strength and damping characteristics, and hardly squeaks during damping.
