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 107 dynes/cm2 or less.
Matériau de frottement (1) destiné à un élément soumis à frottement utile pour la transmission de couple, constitué d'un support (11) présentant une surface avant (12) et une surface arrière (13). Une pluralité de composites de frottement aux formes précises (20) définissant un revêtement de frottement à motif (14) sont fixés à la surface avant (12) du support (11). Les composites de frottement aux formes précises (20) comportent une pluralité de particules de frottement (4) dispersées dans un liant (5). Selon un mode de réalisation, le matériau de frottement (1) présente un module d'élasticité d'environ 10?7¿ dynes/cm?2¿ ou moins.
