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.
Claims4
A composition for an automobile brake lining having a substantially uniform coefficient of friction upon frictional engagement with another member up to 740.degree. F., said composition consisting of metal or metal oxide particles from 15-55 volume percent of the total composition, non-graphitic amorphous carbon particles from 10-75 volume percent of the total composition, an elastomer from 0-10 volume percent of the total composition and an organic resin from 15-35 volume percent of the total composition, said organic resin holding the metal or metal oxides, the non-graphic amorphous carbon particles and the elastomer together, said elastomer attenuating noise created by frictional engagement of the brake lining, said amorphous carbon and metal or metal oxide together forming the friction producing material to create said uniform coefficient of friction.
