X-ray computed tomography datasets of continuous carbon- and glass-fibre reinforced nylon 3D-printed composites under compression

This dataset contains the experimental and numerical data supporting the paper titled “Microstructure–failure interactions in continuous carbon- and glass-fibre reinforced nylon 3D-printed composites under compression.” It includes XCT datasets and processed image stacks for the analysed specimens (UD2 = CFRP_1, UD3 = CFRP_2, XC3 = GFRP_1, XC4 = GFRP_2), raw load–displacement-stress data from additional compression tests, and Abaqus input files (.inp) of finite element models used to assess the influence of specimen geometry on stress distributions. The data support the characterisation of microstructure, fibre orientation, mechanical response, and compressive failure mechanisms, and are openly provided to ensure reproducibility and facilitate further research.
