ABSTRACT:
A friction material particularly useful for vehicle brakes comprises a friction material body including a plurality of steel fibers. Each steel fiber includes at least 0.07% by weight of sulphur, at least 0.10% by weight of phosphorus, or at least 0.15% by weight of both sulphur and phosphorus. The friction material exhibits high friction coefficients and less abrasion with respect to materials against which it bears as compared to conventional wear materials utilizing steel fibers.
