A wound clutch facing is made from a glass yarn of a rough physical form and a binder. The glass yarn contains at least one continuous filament strand and may for example be a doubled yarn or a yarn having a structure in which a sliver of staple glass is wound on a continuous filament core, or a yarn with a core (8) structure out of which loops (9) project at intervals. The latter yarn can be made by a wrapping technique. The binder can include both thermoset resin and rubber. The method for the manufacture of the clutch facings consists in first impregnating the yarn, then winding the impregnated yarn into the form of a facing and press-curing the facing. |
