Wet frictional material containing activated carbon fiber
 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.
