Abstract
[Problems]To provide a wet paper friction member which has high torque capacity and excellent thermal stability simultaneously. [Solution Means]A wet paper friction member is produced by impregnating thermosetting resin into a paper body; curing it with heat; and then forming it with pressure. A fiber base material comprises 20-80 wt % of the paper body and comprises cellulose pulp, aramid pulp, and homopolymer acrylic pulp the drainability of which is adjusted to 120-280 ml, and thermosetting resin such as straight phenol resin, alkyl modified phenol resin, epoxy modified phenol resin, tung oil modified phenol resin, cashew oil modified phenol resin, tung oil/cashew modified phenol resin is impregnated at 20-40 wt %, and thereby, high torque capacity and heat resistance, and mechanical strength are realized simultaneously.
