Abstract: Disclosed herein are a process for producing a carbonaceous thin plate comprisingdisposing a composite material comprising a carbonaceous raw material which is carbonized and solidifies after being softened by heating and paper-like substances which are carbonized without melting between the pressing-surfaces of a heating press, so as to sandwich said carbonaceous raw material between said paper-like substances and to contact said paper-like substances with each of the pressing-surfaces of said heating press,press-molding said composite material by raising a temperature of said heating presscontinuously heating the thus press-molded composite material under a pressure, thereby carbonizing the thus press-molded composite material, andcalcining the thus carbonized material under a reduced-pressure or in an inert gas.

Abstract: Disclosed herein is an organic friction material comprising 5 to 25% by volume of metallic fiber, 3 to 40% by volume of activated carbon, 3 to 15% by volume of carbon fiber, 7 to 47% by volume of an organic and inorganic filling material and 10 to 30% by volume of phenolic resin.
