Abstract


This study demonstrated the first ultra-lightweight composite stiffened panel designed based on an SHM and rapid repair system. First, the feasibility and technical merit of the new design concept was discussed along the lines with the current damage tolerance philosophy. Next, the new design concept was validated using compression after indentation tests of composite stiffened panels. It was confirmed that the ultralightweight structures can be operated as safely as conventional structures, and massive weight reduction is possible with the proposed concept.
