PROBLEM TO BE SOLVED: To obtain the subject friction material having good fade characteristics and brake effect stability and suitable for disk brake pads, etc., at a low cost by using sepiolite fiber, cellulose fiber, etc., in at least a part of a fiber substrate. SOLUTION: This friction material consists essentially of (A) a nonasbestos- based fiber substrate, (B) a thermosetting resin binder and (C) a filler, and the component A comprises a combination of plural non-asbestos-based fibers, and the friction material contains (i) 1-20wt.% sepiolite fiber, (ii) 1-25wt.% cellulose fiber and (iii) 1-10wt.% acrylic pulp as a part of the component A. Furthermore, a weight ratio of the component (i) to the component (ii) is preferably 1: (1-3) and the friction material contains preferably 5-40wt.% component A, 5-20wt.% component B and 30-80wt.% component C. |
