PROBLEM TO BE SOLVED: To provide a method for producing a friction material composition comprising mixing a fiber component/binder component/filler component mixture with 1-12 vol.%, based on the entire composition, cashew polymer/furfural (chemical formula: C<SB>4</SB>H<SB>3</SB>OCHO) mixture and to provide a method for producing a friction material comprising forming the above composition by the above method and molding and heat-treating the formed composition. SOLUTION: The method for producing the composition comprises mixing a fiber component/binder component/filler component mixture with 1-12 vol.%, based on the entire composition, cashew polymer/furfural (chemical formula: C<SB>4</SB>H<SB>3</SB>OCHO) mixture. The method for producing the material comprises forming the above composition by the above method and molding and heat-treating the formed composition. According to the method for producing the composition, ducting and segregation can be prevented because the composition contains the cashew polymer/furfural mixture as at least part of the composition. According to the method for producing the material, the mechanical strengths and the friction performances can be improved because of the use of the above composition. According to these methods, it is possible to obtain a friction material composition and a friction material which can be desirably used for or as disk brake pads, brake linings, etc. COPYRIGHT: (C)2004,JPO
