摘要: 以轻质夹芯板类结构件为主要研究对象,根据结构的断裂破坏形式,开展了结构自修复设计和实现方法的研究。通过增材制造技术完成结构样件的制备,并进一步通过实验测试对比分析了修复后结构力学性能的恢复效果。研究结果表明所设计的夹芯板自修复结构对裂纹具有较好的修复能力,修复后结构的抗压力学性能恢复到原结构的85.6%。

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
