Abstract

A friction lining for a clutch disk for a frictional clutch which is manufactured from a preform article wound from strand material and subjected to a hot pressing process. Glass fibers of the friction lining are at least partially replaced by mineral fibers for minimizing abrasive behavior. The short glass fibers and other components such as aramide fibers, polyacryl nitrile fibers as well as artificial mineral fibers are processed into a non-woven fabric in a carding step and strips of the fabric, with the inclusion of at least one metal wire, are twisted to form the strand material. The strand material manufactured in this manner is impregnated with binding agent and filling agents and is processed into a preform.
