Paper Abstract

The main research is thermal strain sensing characteristics of epoxy resin in fiber Bragg grating (FBG) packaging process. The results of experiment showed that modified epoxy acrylate resin which is often used to package FBG, occurred glass transition at about 65°C, of which the thermal strain sensing sensitivity decreased. Meanwhile, this study showed that FBG is packaged by the modified epoxy acrylate resin after heat treatment has the effect on strain measurement. The experiment indicated that strain measuring consistency and repeatability of FBG has been significantly improved after heat treatment at high temperature 120°C. Finally, a FBG packaging technology about curable epoxy resin curing at room temperature is proposed, and it can improved strain and temperature measuring consistency and repeatability.
