Paper Abstract

The curing monitoring of polymeric composite materials has attracted wide interests recently. Monitoring the curing process is necessary to improve the performance of Gr/Epoxy composites, especially for the characterization of residual strains after manufacture. This paper aimed on exploring the use of embedded fiber Bragg grating (FBG) to monitor the characterizations of the curing process in a Graphite/Epoxy composite. The curing development and residual stress measurement were assessed through changes in the shape of the optical spectra, intensity attenuation and shifts in wavelengths in the optical fiber sensors. The curing caused residual stress was presented and analyzed systematically in this paper.
