            Development of a modular heating system made of recycled carbon fibre
            nonwovens for use in forming and preforming tools



            Both the increasing use of carbon fibre reinforced polymers (CFRP) and prog-  Period
            ress in recycling of CFRP parts as well as preparation of production residues   01.01.2020 – 30.06.2022
            cause a high demand for applications of the obtained recycled carbon fibres
            (rCF) and semi-finished products produced therefrom (e. g. rCF nonwovens).   Project Director
            Due to beneficial electrical properties, carbon fibres show great potential for   Prof. Dr.-Ing. Niels Modler
            use in heating elements, which offers new perspectives for application.
            The aim of the project ReCar, which is funded by the BMBF within the Central   Contact Person
            Innovation Program for small and medium-sized enterprises (ZIM), is the devel-  Ron Luft

            characterization of the electrical properties of rCF nonwovens is, among other
            things, required for the system’s design. For this purpose, an experimental   Funding

            electrical resistance of the rCF nonwovens as well as taking thermographic   and Energy (BMWi)
            images during heating. The goal is an optimization of the temperature homo-  •  German Federation of Industrial
