Friction material composition, friction material, and friction member

Abstract

Provided is a friction material composition that can increase the coefficient of friction and the wear resistance, reduce the compressive deformation rate, and improve the yield upon hot forming, even when being free of copper component or having a small content of copper component. The friction material composition contains: titanate compound powder made of non-fibrous titanate compound particles; barium sulfate powder; and a thermosetting resin, wherein the titanate compound powder has an alkali metal ion dissolution rate of 15.0% by mass or less, the barium sulfate powder has a volume-based 50% cumulative particle diameter (D50) of 0.1 μm to 20.0 μm, and a content of copper component is 0.5% by mass or less in terms of copper element in a total amount of 100% by mass of the friction material composition.
