Preforming Textile Technology
One objective in the context of preforming is to simplify or avoid currently enormously costly sub-processes like cutting and draping by textile-technological means.
The aim of enhancement and innovative development of textile technologies, e.g. based on weaving, knitting and warp-knitting is to create conditions for a direct, single-step production of complex-shape preforms matching the component geometry (direct preforming). This creates the prerequisites for a significant reduction of often manual labor in preforming, and for an efficient use of material, preventing a large amount of fiber waste. Another aim of these developments is to achieve a largely force-flow-adapted orientation of the stretched reinforcement fibers within the components to achieve an optimized use of the reinforcement fibers’ potential, which in turn maximizes the efficiency of lightweight construction.
Another approach is to improve productivity in the production of preforms by increasing the degree of automation in sequential preforming processes. The focus in the examinations is on the fully automated production and fixation, particularly of profile-shaped preforms made from textile fabrics. This requires the development of suitable process steps and equipment, e.g. for the activation of additively inserted fixation material, for a shaping at high geometrical flexibility, the take-off of textile fabrics, and to cut preforms to length.
The know-how gained in the process enables the ITM to act as your partner in the technology, structure and process development for waste-free and near-net shape production of preforms with structures and fixation adapted to further process steps in composite production.
