JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Europe 2013 - A recent project focuses on the processing and development of thermoplastic hybrid yarns (carbon/PA6, glass/PA6.6)
The Composites department of the Institute of Aircraft Design of the University of Stuttgart specialises in research topics related to the design and manufacturing of composite parts based on textile structures. Different projects focus on the whole process chain, from the manufacturing of textile preforms to injection technology through to the finished component.A recent project focuses on the processing and development of thermoplastic hybrid yarns (carbon/PA6, glass/PA6.6). An innovative design and process chain has been developed in cooperation with Weberit GmbH, IPF Dresden, University Siegen, Tajima GmbH and TIME GmbH. It has been proven and tested successfully, using the example of a torque supporter for compact cars. Multifunctional parts can be designed using the tailored fibre placement (TFP) technology in combination with a new grouting and overmoulding process. The grouting tool exactly displays the topography of the embroidered preforms. The tool topography is derived using a software tool called EDOPunch developed by IPF. Thus, a constant grouting pressure is guaranteed in every part of the preform and all the fibres stay in their defined positions. This ensures a maximum weight saving potential and repeatable quality. The production process is very fast due to the short curing time of the PA6/PA6.6 matrix and addresses medium- to high-volume production. There are also very low cut losses due to TFP near-net-shape production.More information:www.ifb.uni-stuttgart.deBooth Y54-4
