Thin ply angle-ply laminates with central 0° plies, that have previously shown pseudo-ductility in tensile loading, have been experimental investigated under several different load cases. These include open-hole tension, compression, bending, fatigue loading and bearing loading, since the design of carbon fibre composite structures is often limited by their behaviour under these load cases and the failure is often catastrophic in many of these load cases. The behaviour of these laminates under different loadings were found to be significantly affected by a combination of prepreg properties, layups and angles in angle-ply. An overall promising behaviour has been observed, including a reduced notch-sensitivity in open-hole tension, compressive fibre fragmentation, progressive failure in bending via fibre fragmentation in the specific sequences on the tensile and compressive sides of the beam, good fatigue performance in both pristine and damaged specimen and gradual failure in bearing.
