Abstract
A superior friction material having high mechanical fatigue resistance and a stable dynamic coefficient of friction over a wide temperature range is prepared from an intimate mixture of an epoxy-rubber binder and friction modifying materials. The material is formed by mixing the uncured epoxy resin with the rubber and friction modifying materials, forming the mixture into the desired shape while soft and pliable, and then heat curing the mixture.
