Abstract
Curved profiles are essential components in lightweight constructions. Besides weight reduction, the preservation or even the improvement of functions in the component are pursued. Space-frame concepts are an option to achieve these aims, in which straight and curved extruded profiles are applied. With regard to design aspects, curved profiles gain in importance. Conventionally curved aluminum profiles are manufactured by the process chain including straight bar extrusion, stretching and bending. In comparison to conventional bending processes, the innovative curved profile extrusion offers great advantages concerning a precise, flexible, and cost effective production as well as the possibility to use innovative lightweight materials, such as magnesium or reinforced alloys. Besides the process principles and advantages, several results of investigations of fundamental and application-oriented research in the field of curved profile extrusion are presented in this paper.
