摘要：
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 res- toration effect of the repaired structural mechanics properties was compared and analyzed through ex- perimental 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. © 2024 Chinese Mechanical Engineering Society.
