  • Friction material reinforced with steel and cellulose fibers
    Patent number: 4119591
    Abstract: An asbestos free organic base friction material for use as a friction lining of a brake. A combination of fibers selected from a group consisting of steel, cellulose, glass mineral and rayon fibers and a thermosetting resin binder are combined with cashew nut particles, elastomeric modifiers and inorganic modifiers to produce an organic base friction material having a substantial stable coefficient of friction over the normal operating range of the brake.

  • Carbon metallic friction composition
    Patent number: 4051097
    Abstract: A composition for an automobile brake lining having a substantially uniform coefficient of friction up to 1000.degree. F. The composition is primarily a mixture of metal or metal oxide particles, non-graphitic amorphous carbon particles, a thermosetting phenolic resin and an elastomer. At least five volume percent of the metal and non-graphitic amorphous carbon particles is in fiber form to provide structural stability to the composition upon curing the phenolic resin.
