Using 3D weaving for additive manufacturing of ceramic preforms

The production of ceramic high-performance composites is essentially an additive process in which near-net-shape manufacturing is aimed for the textile semi-finished products. In this context, state-of-the-art textile machines, in conjunction with computer-aided methods for binding and stress simulation, enable the targeted design of complex 3D structures. Carefully adapted process parameters are essential for processing ceramic fibers in order to achieve a low-damage result. Ceramic fiber preforms are produced in one step and in series. These are used for the production of ceramic high-performance composites. The potential of 3D weaving technology, which is also predestined for the implementation of load-adjusted yarn runs, is illustrated by an airfoil for gas turbines.
