Abstract
A friction liner having a flat, annular general form, for a friction device designed to operate in a liquid medium, consists in particular of a clutch friction wheel or a brake disc, especially for an automatic gearbox or associated with such a gearbox, or a synchronising ring or cone for a manual gearbox. Such friction devices are intended in particular for motor vehicles. The liner is made of a friction material consisting of a mat of fibers impregnated with a thermosetting resin. After a final curing step while the liner is being moulded under pressure, this material has a porous structure with intercommunicating cells. The liner includes zones having different controlled porosities.
