摘　　要：光纤光栅(Fiber Bragg Grating,FBG)传感器由于体积小、信号稳定、与复合材料的相容性好等优点,近年来成为监测复合材料固化过程的首选传感器。本文根据FBG传感器的波分复用技术,形成FBG传感器网络,将该传感网络埋入环氧树脂中,实现了对环氧树脂基板固化过程中树脂温度和残余应变的变化情况的监测,为利用FBG传感网络监测复合材料固化过程提供重要的实验基础。Fiber Bragg grating sensor has been one kind of the sensors firstly considered to monitor the curing process of the composite materials,which has a number of distinguishing advantages,including much less intrusive size,more stable signal,and much better compatible to composite materials,etc.Based on wavelength division multiplexing technology of FBG sensors,the paper aims to monitor the changes of the resin temperature and residual strain of epoxy resin plate in the process of curing through FBG sensing network embedded in the epoxy resin plate,which supplies the experimental foundation for monitoring the changes of the temperature and residual strain of composite materials with FBG sensing network.
