Document Type and Number:

WIPO Patent Application WO/2015/041098

Kind Code:

A1

Abstract:

The present invention addresses the problem of providing a friction material for a disc brake pad, the material being able to maintain braking effect and abrasion resistance at high speeds and high loads while satisfying laws and regulations relating to copper content. The solution to this problem is a non-asbestos organic (NAO) friction material used in a disc brake pad and formed by molding a friction material composition comprising a fiber substrate, a binding material, and a friction adjustment material, wherein used is a friction material composition comprising, as an inorganic friction adjustment material, and with respect to the total weight of the friction composition, 1-10% by weight of one or more selected from the group consisting of aluminum particles, aluminum fibers, alloy particles with aluminum as a primary constituent, and alloy fibers with aluminum as a primary constituent and 5-20% by weight of hard inorganic particles with a mean particle diameter of 1-20 µm and a Mohs hardness of at least 4.5, and the friction material composition also including a total copper content of less than 0.5% by weight.
