ABSTRACT:
A frictional material for brakes employs as a reinforcing material a fibrous material other than asbestos and contains non-fibrous serpentine in the amount of 5 to 80% in contents by volume. The non-fibrous serpentine has the same chemical composition as asbestos but a different crystaline structure. Since the serpentine is non-fibrous, a fibrous reinforcing material must be added. Suitable fibrous reinforcing materials are chopped glass fiber strands, cut steel wires, organic synthetic fibers and ceramic fibers.
