Abstract

Surface-bonded single-mode optical fibre sensors have been used to monitor the interaction of ultrasonic S-0 lamb waves with defects in carbon iibre composite plates. Lamb waves were initiated using Perspex-coupled piezoelectric transducers. The defects investigated comprised holes, regions of impact damage and delaminations. Holes could be identified by analysing direct S-0 reflections and impact damage by S-0 back-waif echo amplitude. Large delaminations gave a poor direct S-0 reflection. Evidence was found for mode conversion at centre plane delaminations.
