Abstract: Taking lightweight sandwich plate structures as the main research object, the self-repairing design and implementation method were studied according to the fracture failure forms of the structures. The structural samples were prepared by additive manufacturing technology, and the restoration effect of the repaired structural mechanics properties was compared and analyzed through experimental tests. The results show that the designed sandwich plate self-repairing structure has a good ability to repair cracks, and the stress resistance of the repaired structure is restoreds to 85.6% of the original structures.

Key words: elytra, lightweight structure, self-repairing, additive manufacturing, crack
