Abstract. To address the limitations of current design safety factors in aerospace structures, accurate simulation models predicting the compressive failure of unidirectional CFRP composites are required. These materials are limited by localized shear instabilities, or kink-bands, which are sensitive to unavoidable fiber misalignment. This study develops a 3D explicit micromechanical model in Abaqus to investigate the morphology of the kink-band failure and explain its scenario. It addresses the existing limitations of imposing the right input parameters and boundary conditions that can produce a kink-band. The simulation successfully captures kink-band formation initiated by matrix shear, fiber rotation and fiber breakage.
