Abstract

A study on the use of fiber Bragg grating sensors to measure strains in thin-walled composite structures is presented. It includes measurement of the gage factor, or strain conversion coefficient, of small diameter fiber optic sensors. Fiber Bragg grating sensor arrays were embedded into high strain composites and the buildup of strains during manufacturing was tracked. μCT scans of these composites were taken after curing to analyze the micro-structure in the regions surrounding the embedded sensors. Composite laminates with embedded sensors were subjected to a controlled coiling experiment to evaluate the accuracy of the sensors in measuring internal strains.
