In this study, we explore the application of multimodal sensors for structural health monitoring (SHM) in carbon fiber reinforced polymers (CFRP) composite panels. The effects of Barley Visible Impact Damages (BVIDs) resulting from Low Velocity Impact (LVI) events were analyzed using three different technologies: distributed optical fiber sensors, piezoelectric transducers, and ultrasonic C-scan. Our preliminary results show that the multimodal sensor approach is beneficial in determining the evolution of BVIDs under compressive fatigue loads, potentially helping in estimating the remaining fatigue life of the monitored structure.

摘要

In this study, we explore the application of multimodal sensors for structural health monitoring (SHM) in carbon fiber reinforced polymers (CFRP) composite panels. The effects of Barley Visible Impact Damages (BVIDs) resulting from Low Velocity Impact (LVI) events were analyzed using three different technologies: distributed optical fiber sensors, piezoelectric transducers, and ultrasonic C-scan. Our preliminary results show that the multimodal sensor approach is beneficial in determining the evolution of BVIDs under compressive fatigue loads, potentially helping in estimating the remaining fatigue life of the monitored structure.
