Abstract: The method for producing a friction material is characterized by defiberizing 10-45 % kraft pulp and 5-15 % linter pulp in the beater to be 400-500 freeness, adding an coagulating agent to the mixed slurry of the pulps, 5-30 % diatom earth, 1-15 % silica, 1- 15 % zeolite, 10-45 % cashew nut shell oil and 1-10 % cardolite, molding the mixt. under the condition of 30 dg/cm2 surface pressure and 50-60 deg.C temp., blanking it to be a fixed size, and heat-hardening it. The friction material for brakes and clutches has a good porosity and durability.
