Abstract
This work presents a feasibility study for steering delaminations through the thickness of composite laminates. The mechanism relies on the fact that delaminations tend not to migrate through plies with fibres oriented in the propagation direction. In this study, plies with fibres oriented in the propagation direction are angled through the thickness in order to steer delamination migration. Both static tests (mode I) and fatigue tests (skin-stiffener debond specimen) have shown the feasibility of this mechanism. Tensile and flexural tests have been performed in order to quantify the effect of this architecture on the global mechanical properties. A significant knockdown in longitudinal tensile strength has been observed, while, the effect on stiffness and flexural properties seems to be less significant.
