The paper investigates experimentally and numerically the response of a smart hybrid thermoplastic composite plate subjected to low-velocity impact. The response of the composite plates embedded with shape memory alloy (SMA) wires embedded is investigated. The SMA wires were embedded within a fabric layer of the composite laminate placed in the middle plane of the laminate. By embedding SMA wires into composites an increase of the damage resistance and ductility of composites structures was observed with respect to conventional composites structures. Moreover, a clear increase of the composites toughness and higher energy levels of absorbed energy before failure was also observed.
