Abstract

The increased production rate targets of the aerospace industry have driven the development of dry fibre infusion processes. Biaxial Non-Crimp Fabrics (NCFs) are considered in this work due to their potential high deposition rates and higher mechanical performance to woven fabrics. Parameters defining NCF architecture, such as stitching, have been observed previously in uniaxial loading using bias extension tests for example. This paper presents an experimental study into this parameter on a large scale (2 metres in span) geometry. The change in stitch direction relative to the geometry leads to distinctive out-of-plane wrinkling. The effect of this parameter on resulting preform quality is observed using 3D scans. Results show differing preform quality in terms of wrinkling phenomena, showing the importance of stitch direction to load for material drapability tests at an industrial scale.
