Abstract

Densified particles of friction ingredients which include an uncured mix of friction ingredients with a thermosetting binder resin and an effective amount of a liquid coreactive with the resin which maintains the temperature during particle formation below the curing temperature of the resin can be used to make friction elements. Methods of forming friction elements from the particles and friction elements made from the particles also are described.
