【 摘 要 】

This paper describes the implementation of a wet compression moulding process using TFP preforms. The fibre paths of these preforms are derived from the actual load paths which are numerically analysed taking into account multiple loading conditions. Preforms are created using a Tajima embroidery machine. This approach allows an innovative way of textile forming in the following process step. This step is based on wet compression moulding using a flexible stamp made of silicone rubber. The wet compression moulding is implemented in the draping test rig of the Institute of Aircraft Design, University of Stuttgart. It is able to produce structures with varying thicknesses which therefore stand out for their high lightweight properties.
