Friction material for a dry friction device, a method of making such a dry friction material, and a dry friction device equipped with such a material

摘要

A dry friction device, in particular a clutch friction wheel or a brake disc for a motor vehicle, includes at least one friction liner made of a dry friction material containing reinforcing fibers.Such a friction material comprises a mat of fibers impregnated with a thermosetting resin, the fibers having a length of at least 40 mm. Glass fibers are preferably incorporated into the mat.
