Abstract

A low spatial resolution Fiber-Bragg-Grating sensor net is proposed for real time health monitoring of bonded composite patches used for aging aircraft structural repairs. FBG reading are shown to have direct correlation with the structural integrity of the patch, making this concept attractive for airworthiness assessment of bonded repairs.
