Novel composites for hybrid lightweight constructions
Neue Verbundwerkstoffe für den Hybrid-Leichtbau
Textile based 2D and 3D metallic wire structures have proven to be a suitable reinforcement for multi-functional composites. Within the described investigations, a systematic transfer of those materials into lightweight applications for automotive and mechanical engineering has been performed together with the development of efficient and economical manufacturing technologies and process chains. The metallic wire structures fabricated by a novel weaving technology are globally unique. After joining the wire structures, they are processed to sandwich composites with metallic surfaces or embedded in metal matrices. Based on an extensive experimental test program, the particular suitability of the developed 3D wire structures for impact applications has been shown. Impact experiments have shown that the energy absorption capability of wire-reinforced materials can be increased up to 600 % compared to conventional materials. Beyond that, with their low weight and high temperature stability, the novel materials are predestined for thermomechanically loaded structures in automotive applications.
