摘要

摘要: 目前复合材料蜂窝夹芯板的修理方式主要采用挖补修理，但仍存在工艺复杂、设备要求高等局限性. 针对设备短缺和时间紧迫的应急场景，迫切需要开发蜂窝夹芯板的快速临时修理方法. 提出了内部补片增强的贴补修理方案，兼具操作简便和可设计性的优势. 通过开展落锤冲击试验，建立复合材料蜂窝夹芯板修理结构的低速冲击有限元模型，结合力学响应曲线和试件破坏形貌特征，对比分析了不同增强方案对修理结构冲击响应与损伤机理的影响规律. 结果表明，传统贴补修理方法中补片与芯层界面存在空隙，影响了修理结构的冲击承载能力；增加内部补片后，延缓了修理胶层的失效，增大了冲击过程中的接触面积. 修理结构抗冲击性能得到大幅提升，并限制了补片在冲击载荷作用下的变形，为快速修理技术研发提供了理论依据.

Abstract: Current repair methods for composite honeycomb sandwich panels primarily employ scarf repair techniques, but they are limited by complex procedures and high equipment requirements. Given equipment shortages and time constraints in emergency situations, there is an urgent need to develop rapid temporary repair techniques for sandwich panels. An internal patch reinforcement repair scheme combining operational simplicity with design flexibility was proposed. By drop-weight impact tests and the establishment of a finite element model for low-velocity impact analysis on repaired composite honeycomb sandwich structures, the effects of different reinforcement schemes on impact responses and damage mechanisms were comparatively analyzed through combination of mechanical response curves with failure morphology characteristics. The results indicate that, interfacial voids in conventional patch repairs reduce the impact load-bearing capacity. Due to the increase of contact area during impact, the proposed internal patch reinforcement enhances the impact resistance with a delay of the adhesive failure a constraint on structural deformation. The research provides a theoretical base for rapid repair technologies in composite structures.
