The authors developed a smart sandwich panel for aerospace structures that could detect impact damages and debonding in honeycomb sandwich structures caused by out-of-plane loadings by using small-diameter optical fiber sensors, such as fiber Bragg grating sensors, embedded in the adhesive layer between the facesheet and the core of the panel. Furthermore, the cell walls of the honeycomb core were made of shape memory alloy (SMA) foils for damage suppression. When the SMA honeycomb sandwich panel with impact damages was heated, the local backlings of the core walls and the deformation of the facesheet disappeared and the bending stiffness of the panel could be recovered.
