[PROBLEMS] To provide a friction material composition and a friction material which do not contain copper having a high environmental load or iron fiber having a problem with rust resistance, have high strength from room temperature to high temperature, have high vibration damping properties, and hardly generate brake squeal. And a friction member. SOLUTION: A premix of an elastomer and an inorganic filler, a binder, a fibrillated organic fiber, an inorganic fiber, and a graphite having a maximum particle diameter of 100 μm or less, containing 6% by volume or more, and an iron-based metal, copper A friction material composition that does not contain. [Selection figure] None |
