Abstract

A central challenge of the Anthropozoic era is the intelligent and efficient use of available material and energy resources. This leads to a steadily growing demand for lightweight solutions based on innovative materials with a broad spectrum of properties and sustainable production technologies. Textile-based structures in general and 3D woven structures in particular offer outstanding possibilities for the realization of fiber-reinforced lightweight structures. In addition, 3D woven structures have an enormous potential for complex medical devices individually adapted to patients. A current challenge, however, is the great effort involved in transferring 3D CAD models into the final 3D component. In order to avoid complex manual process steps, the efficient implementation of a flexible digital process chain is necessary. The aim of the presented work is the development of a continuous process chain for the fully automated production of new complex 3D woven fabric preforms, where the control files for the weaving machine are derived directly from the CAD model via defined intermediate steps.
