Abstract

A deformable sandwich panel is disclosed according to one embodiment. The deformable sandwich panel may include first and second face sheets. These face sheets may each comprise a first and second surface and be substantially flat. The deformable sandwich panel also includes a shape memory material sandwiched between the first face sheet and the second face sheet. The shape memory material may be in continuous contact with a substantial portion of the first surface of the first face sheet and with a substantial portion of the first surface of the second face sheet. The deformable sandwich panel may be fabricated with a first shape, deformed into a second shape and then deployed back to the first shape. The first and second shapes may be maintained without mechanical loads.
