Overview of intelligent composites with embedded FBG sensors

In this paper, the application of fiber bragg grating (FBG) embedded in intelligent composites was outlined, including monitoring the resin flow and residual stress in composites, curing process; structure health monitoring of composites such as strain change, delamination, cracks and other damages in the process of extra-loading. At the end, the problems of embedded FBG in composites were mentioned.
