摘要
在对某型飞机腹鳍的无损检测过程中,发现了面板与蜂窝层的分层损伤。按照飞机结构修理标准工艺相关规定,对损伤区采用铺层打磨蜂窝全厚度尺寸挖补法进行修理,以恢复其气动外形和结构强度并对修补效果进行射线检测评估。实验结果表明,该检测、修理程序合理、可靠,对保障飞机蜂窝复合材料结构件的检测与修理具有重要作用。
In the process of non-destructive testing of an aircraft pelvic fins,delamination damage between the panel and the honeycomb layer was found. In accordance with the relevant provisions of the standard process of aircraft structural repair,the damage area was repaired using overlay layer by layer thickness polished honeycomb full size patching repair method to restore its aerodynamic shape and structural strength,and the repair effect was X-ray detected and evaluated. Experimental results show that the testing and repair procedures are reasonable and reliable,which will play an important role on ensuring the detection and repair of aircraft honeycomb composite structure.
