Claims21
A friction material, the friction material comprising graphite having a c/2 of 0.3358 nm or less and a spring-back of 40% or more.
A method of making a friction material the method comprising the steps of
- (a) providing a graphite,
- (b) subjecting the graphite provided in step (a) to a heat treatment at 600° C. or more for 30 minutes or more;
- (c) mixing the treated graphite obtained at the end of step (b) with further ingredients and treating to form a friction material.
