An investigation of fibre alignment and interlayering of hybrid unidirectional carbon/glass with a randomly oriented elctrocspun polyamide fibre veil composite made with automatic tape and hand laying

Bending and compression of hybridised composites has a wide application in leaf springs and aircraft bodies. Using automatic tape laying, unique carbon/glass fibre hybrids are created with high fibre angle precision. The composites compressive response to different fibre angles is critical in understanding the gap between predictive modelling and actual mechanical performance. The fibre angle was measured, using a micro-CT 3D stacking. The results were used to create an average fibre alignment and with the inclusion of energy of crack propagation to the Lo-Chim and Burdunsky models to improve the estimate compressive strength to within actual mechanical deviation.
