| Research Abstract |
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.
