PURPOSE:The titled friction material, containing a reinforcing material, e.g. glass fibers, lubricant, inorganic filler, resin, etc. in specific amounts, prepared by molding chopped glass fiber strands while leaving the unity thereof, and having improved noise fading property. CONSTITUTION:A friction material, containing 5-60wt% glass fibers as a reinforcing material, 0-30wt% organic or inorganic fivers and 0-25wt% organic dust, 0-20wt% lubricant, 0-25wt% metallic powder, 3-50wt% inorganic filler and 5-20wt% resin, and prepared by molding chopped glass fiber strands while leaving the unity thereof. Preferably, the chopped glass fiber strands impregnated with 0.5-20wt% resin, e.g. phenol or epoxy, or latex, e.g. acrylic or SBR, are used to improve the friction performance. USE:Brakes and clutch facings for automobiles, industrial machines, etc. |
