A friction lining for wet running consists of a fabric which can be applied to a carrier ( ) and is partly impregnated with resin. In order to provide favorable friction conditions it is proposed that the porosity of the fabric ( ) impregnated with resin is higher in the zone of the friction face ( ) by a lower resin content in a surface layer (h) than in the remaining layer.

Friction lining for wet running

A process for the production of prepregs having a high fiber weight of 500 to 2500 g/m.sup.2, in which process fiber strands made of glass carbon, aramid, ceramic, metal or other inorganic and/or organic fiber materials, if appropriate together with woven fabrics, laid fabrics, nonwoven fabrics or mats made from one of these materials, are impregnated with duroplastic resins without additional solvents and fed to a twin-belt press, in whose first part, the pressure heating zone, the impregnated fiber material is converted into the B state under the action of pressure and heat, and in whose second part, the integral pressure cooling zone, the fiber material is cooled under pressure, thus stabilizing the B state.
