摘要:
A friction material composition that enables a friction material, which contains no copper or contains not more than 0.5 mass % of copper, to maintain sufficient friction coefficient in fade conditions at high speed such that brake temperature rises abnormally by repeated rapid braking at deceleration of 0.8 G from a vehicle speed of 200 km/h, is provided. A friction material obtained by molding the friction material composition is also provided. The friction material composition contains a binder, an organic filler, an inorganic filler, and a fibrous base material, and the friction material composition contains no copper as an element or contains not more than 0.5 mass % of copper, and also contains 2 to 5 mass % of steel fibers that have fiber lengths of 800 μm or more.
