clutch disc, made of carbon composite material for a wet friction clutch and method for their production

摘要

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 V2 V1 is established between the porosity V1 of the disk body and the porosity V2 of the friction layer, and the porosity V2 of the friction layer 4 is set in a range of 20 % ≤ V2 ≤ 60 %, which provides a clutch disk with sufficient strength and excellent sliding characteristics.
