Abstract

In the experiment, a fiber Bragg grating embedded in a hollow glass bead/epoxy resin composite was used to monitor the strain changes at different stages of curing, while two free fiber gratings were placed in the oven to realize temperature compensation. At the end of the cooling stage, the minimum strain monitored is - 6123 με. In addition, the study shows that the variation of internal strain in the sample is delayed relative to the temperature change in the oven. This test verifies the feasibility of using FBG to monitor the curing cycle of buoyancy materials.
