  • Patent number: 10173380
    Abstract: An arcuate fiber composite plastic preform and a method for the production of curved profiles with any fiber layer structure are disclosed, which include a layered fiber structure with a base and an arcuate outer contour, an inner edge and an outer edge. The fiber layer structure is configured with a first inner area provided with elevations and depressions, a second adjacent central area with no elevations and depressions and a third outer area and provided with radially oriented open recesses. The method of producing curved profiles from fiber composite plastic preforms having any fiber layer structure includes a molding step, whereby the outer area of the preform with wedge-shaped recesses is being compressed while the inner relief-shaped area is being completely stretched thereby flattening the relief.
