Theoretical and Experimental Studies of Structural Health Monitoring of Carbon Composites with Integrated Optical Fiber Sensors Based on Fiber Bragg Gratings

This paper describes research in the field of fiber optic nondestructive testing and structural health monitoring (SHM) of carbon fiber reinforced polymers (CFRP) by the use of integrated optical fiber sensors (OFS) based on fiber Bragg gratings (FBG). Basic mathematical expressions that represent optical SHM of composites are presented. Some new relationships are derived by considering the non-linear character of the FBG-sensor response and the...
