AUTO-RTM – Concept for a high-automated process chain for the production of RTM-compound-components in large series

Abstract

The goal for the next generation of aircraft in comparison to today’s structures is to reduce the weight and the costs significantly. This objective makes an advancement in the process chain for the manufacturing of composites necessary. Considering cost-effective carbon fibre reinforced parts produced by resin transfer moulding (RTM), textile and preform technologies can contribute to a highly automated manufacturing and low cost process. The project “AUTO-RTM” focuses on the development of technologies for the highly automated production of CFRP parts in the RTM process. Based on the new technologies a concept for a automated RTM production was generated and is currently installed in the workshop of the Technology Center Stade (TZS). After testing the verification of the advantages of automation will be performed. The new technologies are covering all steps of the process chain: - cutting - techniques for handling and adjustment of cuts and preformed components - preforming - concept for RTM-moulds - sealing and closing of the RTM tool - transfer of the mould in the hot press - connection with resin and vacuum supply - RTM process in hot press - opening of the RTM tool - handling of the part - cleaning of the RTM mould
