Patterned surface friction materials, clutch plate members and methods of making and using same

摘要

A friction material (1) for a friction facing member useful for transmitting torque includes a backing (11) having a front surface (12) and a rear surface (13). A plurality of precisely shaped friction composites (20) defining patterned friction coating (14) are attached to the front surface (12) of the backing (11). The precisely shaped friction composites (20) include a plurality of friction particles (4) dispersed in a binder (5). In one embodiment, the friction material (1) has an elastic modulus of about 10<7> dynes/cm<2> or less.
