Patent ID: 7918172

Claim:
A method for producing a three-dimensionally curved fiber-composite material structural component having a predefined flexural member profile cross section with at least one web area and at least one adjacent flange area, comprising the following steps: a) providing a flat base fiber laid scrim that can be draped in at least one plane; b) disposing a unidirectional fiber laid scrim tape with 0° fibers on a partial area of the fiber laid scrim corresponding the at least one flange area; c) fixing the fiber laid scrim tape on the base fiber laid scrim by sewing using at least one first fixation seam so as to provide a flat prefabricated fiber laid scrim strip having a flange strip area including the unidirectional fiber laid scrim tape and a web strip area free of the fiber laid scrim tape; d) disposing the flat prefabricated fiber laid scrim strip in a working plane; e) draping the prefabricated fiber laid scrim strip according to a desired contour, wherein the flange strip area of the fiber laid scrim strip is disposed at an angle of the working, plane with respect to web strip area and is curved monoaxially around at least one axis of curvature extending perpendicular to the 0° fibers and parallel to a tape plane of the fiber tape, and wherein the web strip area of the fiber laid scrim strip is draped essentially only in the working plane so that the fiber arrangement of the web strip area is distorted; and f) sewing the prefabricated fiber laid scrim strip onto a support material that can be draped in at least one plane using at least one second fixation seam provided at a transition area between the flange strip area and the web strip area only in the web strip area so as to provide a stabilized three-dimensionally curved first sub-fiber laid scrim preform that is adapted to the fiber composite material structural component to be produced.
