Textile-reinforced composite components for function-integrating multi-material design in complex lightweight applications

Lightweight structures engineering with textile-reinforced composites offers numerous advantages over conventional designs. Here, function-integrating lightweight structures using multi-material design are particularly significant. Mainly the high stiffness and strength with low weight, the good damping and crash properties, the great variety of textile processes and structures as well as  the cost-effective production with high reproducibility,  the suitability for high-volume series production and the good recyclability really predestine this young material group for future lightweight applications within different industries.

During developing textile-reinforced composite parts for complex applications, the reinforcement and the component structure have to be fitted to one another. This is bound to involve a close entanglement of the design processes of both material and component. Thus, research at SFB 639 is focussing on a continuous treatment of the whole process of developing lightweight structures in multi-material design using textile composites (see figure). The isolated consideration of singular problems, which has been common so far, will not lead to a fundamental gain of knowledge when tackling such a strong interaction of the local and the global structure (from filament up to component part). Only with a continuous, synchronised approach, the high lightweight potential given here can be fully exploited.
