吸波蜂窝夹芯结构在先进飞行器中得到了广泛使用,但是服役过程中的损伤会导致其电磁吸波性能、力学性能发生退化,目前的研究主要集中其力学性能的修复,缺乏对电磁性能修复的综合考量。针对现有修复效果综合评估方法不完善的问题,通过仿真、试验方法综合研究了胶接修理后含损伤吸波蜂窝夹芯结构的反射特性、面内压缩性能。提出定义为修理结构与无损结构最大差值的电磁性能修复性评价指标,弥补了传统指标无法直接表征反射特性变化的不足;量化挖补、贴补工艺参数对力-电性能的影响,并基于模糊综合评价法构建力电综合评价指数CEI。研究结果表明,贴补、挖补修理均会导致吸波蜂窝夹芯结构反射率提高、吸波中心频率向低频方向偏移,且修理结构的电磁性能修复评价指标随修理区域增大而增大;修理后结构力学性能的修复性优于电磁性能修复性,斜率20∶1的单面挖补方案力电综合修复性最佳。

Microwave-absorbing honeycomb is a commonly used Electromagnetic (EM) wave absorbing material of advanced aircraft, but damage during service will lead to degradation in both EM wave absorbing and mechanical performance. The vertical reflectivity and in-plane compression properties of repaired microwave-Absorbing Honeycomb Sandwich (AHS) were studied by simulation and experiments, and a new evaluation index for the EM repairability of damaged AHS, defined as the maximum difference between the repaired and undamaged structure, is proposed in this paper. The effects of bonded repair technology on the mechanical and EM repairability of AHS are analyzed, and a comprehensive evaluation on mechanical and EM repairability is made based on the fuzzy comprehensive evaluation method. The results show that both patch and scarf repair will lead to an increase of structural reflectivity and the shift of absorbing center frequency to low frequency. The evaluation index for the EM repairability increases with the increase of repair area. The mechanical repairability is better than EM repairability after patch and scarf repair. Single-sided scarf repair with scarf slope of 20∶1 is the repair scheme with the best mechanical and EM comprehensive repairability.
