ABSTRACT:
Heat-treated palygorskite clay, such as attapulgite having controlled low moisture and carbonate content, is used with steel wool or other non-asbestos fiber in asbestos-free friction material compositions such as clutch linings, brake pads, truck blocks and the like. These compositions include conventional fillers, lubricants, wear modifiers and the like in order to achieve friction and wear properties comparable to asbestos-based materials.
