During the past years, several textile technologies, such as robot-assisted braiding, weft knitting and textile fibre placement, have been developed and optimized for application in composite structures. In combination with new stitching technologies, these basic fabrics can be combined automatically to complex, 3D reinforced preforms. It has been demonstrated that this approach - combined with adequate infiltration techniques - has a high potential for the cost-effective manufacturing of high-performance composite structures with superior damage tolerance and structural integrity.
