PURPOSE:To contrive to reduce environmental pollution by impregnating a paper-like fabric containing cellulosic fiber, polyamide fiber, glass fiber and frictional property improver with phenol resin. CONSTITUTION:A paper-like fabric containing 5-30wt% of cellulosic fiber such as wood fiber, cotton fiber or the like, 2-30wt% of polyamide fiber such as 'Kevlar' or the like, 2-20wt% of glass fiber, and 30-80wt% of frictional property improver is manufactured by wet paper formation process. Said paper- like fabric is impregnated with phenol resin to form a friction material. The frictional property improver contains fibrous material which can be added at the time of manufacturing, in paper form,titanic acid potash fiber, rock wool, ceramic fiber, carbon fiber and the like in addition to organic or inorganic compounds. |
