New yarn materials for high-performance fibre-reinforced composites made of stitched preforms
The cost-reduced manufacturing of complex textile preforms used for liquid composite moulding of high-performance fibre-reinforced polymer composites is of significant importance for today’s aerospace industry. In order to not outweigh the anticipated improvement of the out-of-plane performance achieved through modern stitching technologies by reduced in-plane mechanical composites properties, innovative stitching yarns were used. As compared to a standard polyester stitching yarn, low melting-temperature polyamide as well as soluble phenoxy yarns are shown to significantly reduce the maximum fibre undulations in the final epoxy composites; effectively allowing a further pre-stabilisation of the dry performs by thermobonding as well as leading to an optimised composite performance.
