Abstract: A method for producing a friction disc includes the steps: providing a carrier element, providing at least one friction lining; connecting the friction lining to the carrier element by an adhesive agent to form a composite material, wherein the carrier element is connected to the friction lining to form the composite material before the geometry of the friction disc is determined.

Abstract: The invention relates to a friction plate (10) having a ring-shaped plate body (4, 9), which is closed in the circumferential direction (13), and has multiple recesses, and is delimited by a radially inner face surface (11) and a radially outer face surface (24).

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.

Abstract: The invention describes a friction lining (4) comprising a binding agent matrix (5) and friction particles (6), which binding agent matrix (5) forms a coating with a pre-definable coating thickness. A proportion of the friction particles (6) selected from a range with a lower limit of 20% and an upper limit of 100%, by reference to the total quantity of the friction particles (6), has a diameter which is bigger than the coating thickness of the binding agent matrix (5).
