Ultrasonic guided wave monitoring of composite structure: impact detection and localization with Fiber Bragg Grating sensors

Résumé

Fiber Bragg Grating sensors record the ultrasonic signature of impacts on aeronautic composite structures. Experiments with 4 FBG sensors show proper localization of impacts with around 1 cm precision using an algorithm based on time of arrivals of guided waves.
