Abstract: A method of producing a friction lining for wet operation resinates a textile fabric of staple fibers with a resin or resin mixture and then the textile fabric is cured under pressure or at an increased temperature. The resin or resin mixture is cured in at least two steps. In a first step the resin or resin mixture is pre-polymerized 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. 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.
