In this research, the health monitoring technique for the detection of impact damages on the scarf-repaired composites is established. We detect the debondings of adhesive layer by using the Lamb-waves propagating in structures. We visualized Lamb waves propagating in scarf-repaired composites by pulsed-laser scanning and observed the change in the behavior of wave propagation due to the damages. We applied this technique to the scarf-repaired specimens with artificial defects. In these results, the reflection and scattering of the elastic waves at the boundary of defects were observed. These results indicate that this visualization technique is effective for the detection of impact damages in scarf-repaired composites.
