The aim of the project was the development of a sustainable sandwich composite material with a core made of cork or recycled PET, prepreg face sheets made of recycled carbon fibers (rCF) and a bio-based solid epoxy resin. By using a solid resin, it was possible to replace the classic vacuum infusion process with a more resource-efficient process variant that requires significantly fewer auxiliary materials. Crucial for this was the development of prepregs at IVW. For these, the textiles were not impregnated – as usual – over the entire surface, but in a pattern form. The pattern impregnation improves the evacuation behavior of the prepregs and allows draping at room temperature. Within the scope of the project, the influence of various pattern and process parameters on processability and achievable laminate quality were investigated. The results were published in the Polymer Composites Journal (https://doi.org/10.1002/pc.27696). In cooperation with the project partners Swiss CMT AG and GREENBOATS GmbH, a demonstrator in the form of a foil board was manufactured by using the newly developed material and process technologies.
