Research on Self-repairing Structure Design and Repair Performance Based on Additive Manufacturing Technology
Taking lightweight sandwich plate structures as the main research object,the self-re-pairing 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.
