N2 - The heterogeneous deformation and damage behaviour of woven composites benefits from advanced characterisation techniques, including micro-computed tomography (micro-CT). This paper uses high-resolution micro-CT images of a woven carbon fibre/polyetheretherketone (C/PEEK) laminate to compare with digital image correlation (DIC) during experimental loading and to provide the architecture for an accurate mesoscale numerical model. The mesh for the finite element model is created from the segmented phases (fibre tows, matrix, and voids) of the micro-CT volume. The combined experimental and numerical approach provides detailed insights into how defects and architectural variations, such as voids and layer alignment, influence the 3D deformation and damage development.
