The manufacturing of prepreg based fibre composite parts generally requires multiple process steps and curing via autoclave. This leads to long cycle times and high investment costs. RWTH Aachen University demonstrates how to overcome these problems by the usage of novel partially impregnated prepregs based on tailored textiles.

High Component Prices

In the steadily growing market for carbon fibre reinforced plastics (CFRP), pre-impregnated reinforcement textiles, so-called prepregs, play a major role. With a market share of approximately 45 %, prepreg-based processes generated a worldwide turnover in 2015 of approximately € 4.4 billion [1]. The technology is mainly applied for the production of parts with high quality requirements and for series smaller than 10.000 pieces/year [2]. For up to 1000 pieces/year, the deposition and the stacking of the prepregs are generally done manually. For this, UD-prepregs or prepregs based on woven fabrics are cut into shape and then layered to form...

Thanks

The IGF project “Tailored Prepreg” (No. 19441 N) of Forschungsvereinigung Forschungskuratorium Textil eV, Reinhardtstraße 12-14, 10117 Berlin is funded by AiF within the program for the promotion of industrial joint research (IGF) by the Federal Ministry of Economics and Energy BMWi on the basis of a decision of the German Bundestag. We would like to thank the participating project partners as well as the members of the project accompanying committee for their cooperation and the support of the research work.
