Document Type and Number:
WIPO Patent Application WO/2020/255279
Kind Code:
A1
Abstract:
Provided is a friction material composition that can obtain an excellent friction coefficient during repeated normal braking and has excellent stability of the friction coefficient by using a material having little environmental load and harmfulness to the human body. Also provided are a friction member and a friction material that use the friction material composition and a vehicle equipped with the friction member or the friction material. Specifically, the friction member is a friction member having a friction material and a back metal, wherein the friction material does not contain copper or else has a copper content of less than 0.5 mass% as copper element and contains a total of from 0.1 mass% to less than 8.0 mass% of two or more metal sulfides including bismuth sulfide.
