Kurzfassung

Fibre reinforced polymers (FRP) are important materials used in aviation due to their excellent mechanical properties combined with relatively low weight enabling the reduction of fuel consumption. For example, expensive and energy intensive carbon fibres are used in primary and secondary structures. However, all composite materials used currently in aviation have one thing in common: they are man-made. Renewable materials like bio-fibres and bio-resins are under investigation for a long time as an economically and ecologically improved alternative for composites. However, they did not made it into modern aircraft in noteworthy amounts yet. The application of ecologically improved materials is under investigation in the international research project ECO-COMPASS, a collaboration of Chinese and European partners. One aspect of the project is the improvement of the mechanical properties of natural fibre reinforced composites. [1] This presentation will give an outlook on the potential of hybrid composites made of natural fibres and recycled carbon fibres (rCF). The aim is to find a possible application for the valuable pyrolysis recycled carbon fibres that retained their very good intrinsically mechanical properties but lost their theoretical infinitesimal length [2]. Therefore, simple nonwoven have been manufactured on a small scale carding device at the German Aerospace Center (DLR). Composites have been manufactured with Single Line Infusion (SLI) method to compare different variants of reinforcements on monolithic composite level. It will be shown that the addition of recycled carbon fibres to a flax nonwoven leads to a significant increase in flexural strength and stiffness compared to a composite reinforced purely reinforced by flax fibres.
