Based on the sensing principle of optical fiber grating,a kind of fiber Bragg grating(FBG)sensor packaged in glass fiber/epoxy composite substrate was designed and fabricated.The glass fiber/epoxy composite laminate was used as the bottom substrate,and the glass fiber fabric was used as the covering layer.Then the FBG was encapsulated between the bottom substrate and the covering layer by means of a vacuum-assisted infusion process of liquid epoxy.The only once but fully curing and the pre-curing processes ...
