ABSTRACT:
A non-asbestos friction material containing a reinforcing fiber other than asbestos, organic fillers, friction adjusting ingredients, and a thermosetting resin for binding the reinforcing fiber, the organic fillers and the friction adjusting ingredients together. The friction adjusting ingredients contain magnesia in the form of aggregated particles which are an aggregate of minute particles. The use of magnesia in the form of aggregated particles reduces low-frequency noise and squeak while keeping the attack on the mating member low and keeping high the resistance to fading and the coefficient of friction.
