ABSTRACT:
A process for producing a friction material is disclosed, which comprises integrally bonding a preform of a friction material molding compound by heat-forming to a metallic backing plate which has been formed into a given shape and has undergone degreasing and priming, said heat-forming being conducted after the backing plate has been preheated to a temperature about equal to the heat-forming temperature to be used. The process is effective in simplifying the temperature control conducted in the heat-forming step and in providing high-quality friction materials always having stable physical properties and performances.
