The three cooperation partners, Dieffenbacher, KraussMaffei and the Fraunhofer ICT, have pooled their expertise and set themselves the goal of working together on product-oriented develop-ments for the global marketing of turnkey systems for the high-pressure resin transfer mol-ding (HP-RTM) process. Together, the partners are capable of delivering the entire process sequence from unwinding the textile semi-finished product (e.g. CFRP fabric) through to final processing of the finished composite fiber component, by means of turnkey machinery with high system competence.
Machines in production status have been set up at the Fraunhofer Institute for Chemical Technology using the latest Dieffenbacher press and system technology as well as a KraussMaffei HP-RTM injection machine. By using the extensive materials competence that is available on site, it is possible to advance the development of machines and pro-cess technology comprehensively. In this way, the technological leadership enjoyed by the cooperati-ve venture is being strengthened in the long term and indeed boosted even further.
