Abstract
A wet frictional material comprises a fiber base material such as natural pulp fibers or organic synthetic fibers, a filler such as diatomaceous earth or cashew resin, a friction adjustment agent, thermosetting synthetic resin, and activated carbon fibers so that the wet frictional material is high in friction coefficient and superior in heat resistance.
Claims4
A wet frictional material comprising:
- fiber base member, filler member, friction adjustment member, thermosetting synthetic resin and 1 to 40% by weight of activated carbon fibers, wherein said activated carbon fibers have diameters in a range of from about 1 .mu.m to about 50 .mu.m and lengths in a range of from about 0.1 mm to about 30 mm;
- said fiber base member, said filler member, friction adjustment member, and said activated carbon fibers being bound to each other by said thermosetting synthetic resin.
