Patent ID: 8303747

Claim:
Method of producing a friction lining for wet operation, whereby a textile woven fabric of staple fibers is resinated with a resin or resin mixture to form a textile woven fabric/resin mixture wherein the resin or resin mixture is present in a proportion between 40 wt. % and 70 wt. % with reference to the textile woven fabric/resin mixture and then cured under pressure and/or at an increased temperature, and the resin or resin mixture is cured in at least two steps, and in a first step the resin or resin mixture is pre-polymerized at a temperature between 150° C. and 250° C. to produce a pre-product and final curing of the resin or resin mixture takes place in another step once the pre-product has been placed on a substrate, wherein the pre-polymerization of the resin or resin mixture is run without pressure and staple fibers with a length selected from a range with a lower limit of 30 mm and an upper limit of 200 mm are used, the friction lining having a porosity between 2000 μm/Pa s and 2500 μm/Pa s.
