Arcuate fiber composite plastic preform and method for production of curved profiles
First Claim
1. An arcuate fiber composite plastic preform for the production of curved profiles comprising,a fiber layer structure forming a plane or curved base with an arcuate outer contour bordered by front ends, an inner edge with a curvature facing a center of a curve and an outer edge with a curvature facing away from the curve, said fiber layer structure configured with, a first inner area, starting from the inner edge, with a surface including a relief structure along an extent of the curve with elevations and depressions vertical to the base,a second area starting from the first inner area and extending outward to an adjacent central area as a base and void of elevations and depressions, anda third outer area starting from the base extending outward and adjacent the outer edge, said outer edge provided with radially oriented open recesses.

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.
