In the current work, a combined non destructive methodology is proposed in order to investigate the static and fatigue damage of carbon fiber reinforced epoxy composites. Flat angle-ply laminates are used in order to examine the influence of multiaxial stress states on the mechanical performance using different non destructive techniques. Acoustic emission is combined with an online microscope and digital image correlation and this combination is used to comprehend the performance of composites with unequal stress states.
