ABSTRACT:
A method for producing a three-dimensionally curved fiber composite material component having a predefined flexural member profile cross section with at least one web area and at least one adjacent flange area, includes providing a flat base fiber laid scrim and disposing a unidirectional fiber laid scrim tape with 0 degree fibers on a partial area of the fiber laid scrim and fixed by sewing so as to provide a flat prefabricated fiber laid scrim strip having a flange area including the unidirectional fiber laid scrim tape and a web strip area free of the fiber laid scrim. The prefabricated scrim tape is draped to a desired contour and is sewn onto a support material so as to provide a stabilized three-dimensionally curved first sub-fiber laid scrim preform adapted to the fiber composite material structural component to be produced.
