摘要

A qualified value-added chain for the re-use of recycled carbon fibres (rCF) as nonwovens in sophisticated fibre-reinforced plastics has been set up within the research project RecyCarb. The progress in processing technology was accompanied by setting up a reliable scheme of quality assurance. This article focuses (1) on the use of different web formation and bonding technologies to produce nonwovens (carding / airlay), ranging from highly-oriented to quasi-isotropic nonwoven structures, and (2) on the achievable mechanical properties of fibre-reinforced plastics produced using different processes from a range of typical rCF lots. Press-moulded composites reached tensile strength of approx. 530 MPa (CD) & 330 MPa (MD), and Young's moduli of 50 GPa (CD) and 31 GPa (MD). Similar values were obtained by resin-transfer moulding (RTM). Prepreg-based composites displayed tensile strength up to 330 MPa and Young's modulus up to 29 GPa. In addition, first experiments showed that repeated recycling of carbon fibres is possible with minor loss of stability.
