Rapid repair of CFRP structures monitored by structural health monitoring systems

本研究以实验与数值模拟相结合的方式，探讨侦测损伤资讯的不确定性对修补零件强度的影响。对试件进行了模拟冲击或雷击损伤，并对修复后的试件进行了拉伸试验。结果表明，在考虑损伤信息不确定性的情况下，通过合理确定碳纤维布修补片的尺寸，可以满足修补件的强度要求。此外，所需的能力的冲击损伤检测系统相结合的快速修复方法被确定。

This study experimentally and numerically investigated effects of the uncertainty about detected-damage information on the strength of repaired parts. Simulated impact or lightning damage was introduced in specimens, and tensile tests were conducted using them after repairing. It was shown that the strength requirement of the repaired part can be fulfilled by deciding the size of the CFRP repair patch in consideration of the uncertainty about the damage information. Furthermore, required capability of an impact damage detection system combined with the rapid repair method was identified.
