NON-ASBESTOS FRICTION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a non-asbestos friction material used for rotors and brake drums made of aluminum alloy for automobiles, having small face-attacking property and excellent abrasion resistance. SOLUTION: The non-asbestos friction material is obtained by molding and curing a non-asbestos-based frictional material composition consisting mainly of (A) a fiber base, (B) a binder and (C) a filler. The non-asbestos friction material for rotors or drums made of aluminum alloy comprises 1-10 vol% abrasive particles having 0.5-10μm average particle diameter and 4-20 vol% unvulcanized rubber based on total friction material in the filler (C).
