ABSTRACT:
A non-asbestos-based friction material for brakes, clutches or the like for automobiles, large-size trucks, railway cars and various industrial machines. The friction material has excellent friction and rust preventive characteristics, and attacks the plane it faces to a limited extent. The non-asbestos-based friction material is produced by forming and then curing the non-asbestos-based friction material composition comprising a fibrous base, binder and filler as the major ingredients. The composition contains at least one type of steel fibers selected from the group consisting of iron, special dead soft steel and dead soft steel, containing carbon (C) at 0.13% or less at specific contents, in the fibrous base at 1 to 50% by volume of the whole friction material.
