<title>Adhesively bonded optical sensors: stress transfer and durability</title>

In this study, adhesively bonded optical fibers and Bragg grating sensors were investigated. The primary objectives were to assess the durability of the optical fiber-to-composite bond during loading and how that load was transferred from the structure to the optical fiber sensor. Using a two-phase epoxy and a highly reproducible bonding technique, different specimen configurations were fabricated and tested under cyclic fatigue loading. The...
