  • Patent number: 5714525
    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.

  • Patent number: 5360587
    Abstract: A method for preparing a friction element from rod-like particles of friction ingredients includes preheating the particles, which have a diameter of about 3/32" to about 1/4", to a temperature between 150.degree. F. and 375.degree. F., introducing a predetermined amount of the preheated rod-like particles into a friction element mold, and compressing the preheated rod-like particles under heat and pressure to form the friction element. Compositions for forming the rod-like particles are disclosed.
