Embedding SMA layers in a composite structure is a promising technology to improve mechanical features, but this achievement must not come at the cost of structural integrity. The research carried out within this paper was focused on assessing the delamination behavior of hybrid composite structures, specifically, ones composed of layers of a Cu-based shape memory alloy (SMA) and a glass-fiber reinforced polymer (GFRP). Different patterns of holes cut into SMA layers of a composite material have the potential to produce topologies that can be applied for improved damping in lightweight structures. To make an initial assessment of the effects of different hole patterns on the structural integrity of the composite, the authors have designed an experimental setup intended for the application of Mode II (shear) loading to the composite samples up to the point of failure.
