Abstract: This paper presents the shock response of unidirectional carbon fibre reinforced polymer (UD CFRP) with two distinct fibre orientations, when subjected to plate-impact experiments. Samples of CFRP were prepared with fibres aligned at 0° and 90° relative to the direction of impact, where 0° represents fibres parallel to the impact trajectory. The study reveals the initiation and progression of a shock front within the CFRP composites. Significantly, the 0° oriented samples exhibited elevated transmitted shock wave amplitudes and velocities in comparison to the 90° samples, under identical conditions of impact velocity, sample thickness, and flyer material. This suggests that the shock wave’s behaviour is markedly affected by the fibre orientation. Additionally, a dual-wave structure was detected in the 0° samples, characterized by a leading wave propagating at the longitudinal sound speed of the composite, followed by a slower-moving shock front.
