Abstract

The imminent climate change, the increasing environmental pollution or the dwindling of resources - all these points have made lightweight design more and more relevant for many different industries. Whenever masses in motion can be reduced, the energy efficiency, and therefore, the sustainability of a product is increased. A common way to reduce the weight of technical products or systems is the use of lightweight materials like aluminium or titanium. However, over the last few years and decades a novel material class has become more and more popular in lightweight design - the so called composite materials where a weak matrix material is reinforced with fibres. The aim of this paper is to show the challenges in the design of composite structures and, for the first time, to give a complete overview of a novel computational design approach which was developed over the last few years. It should be pointed out here that the regarded composite parts in this article are thin-walled parts made of endless CFRP with an unidirectional fibre reinforcement.
