Abstract
A clutch disk made of a C/C composite for a wet multi-plate clutch is comprised of a disk body, and a pair of friction layers integral with and on opposite sides of the disk body for sliding contact with clutch plates. A relationship of V.sub.2 >V.sub.1 is established between the porosity V.sub.1 of the disk body and the porosity V.sub.2 of the friction layer, and the porosity V.sub.2 of the friction layer 4 is set in a range of 20%.ltoreq.V.sub.2 .ltoreq.60%, which provides a clutch disk with sufficient strength and excellent sliding characteristics.
