Paper Title:
Embedded Fibre Bragg Grating Sensors for Internal Fatigue Damage Monitoring in Polymeric Composites
  Abstract

This work aims at assessing the use of embedded fiber Bragg grating to monitor the internal damage evolution in polymeric composite during fatigue loading . The results suggested that the embedded FBGs have good potentials to detect the appearance of damage and to differentiate the damage types. The evolution in light spectrum during fatigue may be divided into four stages when compared against X-ray, C-scan and optical microscope (OM) results. These stages are associated with (1) matrix cracking in 90o lamina; (2) fiber splitting in the ±45o laminae; (3) fiber splitting in the 0o lamina ; and (4) delamination.
