Process to produce fiber composite components – Near-net-shape fabrics in preforms

For a cost-efficient mass production of fiber composite components, it is essential to optimize the preparation of the near-net-shape textile preforms. The actual process consists of the manufacturing of standard textile semi-finished materials and therefore results in a discontinuous and cost-extensive procedure. The several working-steps – cutting to form, handling and fixing of the parts – are time-consuming and generate a big loss of valuable material. The process object of this invention takes advantages on the use of near-net-shape fabrics. Here single textile reinforcement elements are joined in a continuous process to form the final preform. The process described increase significantly the productivity of the production process of preforms and constitutes therefore a basis for the serial production of fiber composite components. Furthermore this technology can be integrated in an existing chain process in order to upgrade it. On behalf of the RWTH Aachen, PROvendis offers the license to the technology and the possibility to establish a scientific cooperation for further development.
