    摘要: 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.

    摘要: A friction material, including a fibrous reinforcement, a friction modifier, a lubricant and a binder, comprising a water-repellent fluoropolymer incorporated therein. The further incorporation of an alkaline metal salt makes it possible to render the matrix more hydrophilic and hence reduce creep noise. The foregoing fluoropolymer is one selected from the group consisting of ethylene tetrafluoride polymer, tetrafluoroethylene-hexafluoropropylene copolymer and polyvinylidene fluoride or a combination thereof.
