摘要
介绍了光纤布拉格光栅(FBG)传感器的基本原理及优点,开发了基于光纤光栅技术的温度传感器和应变传感器,并对它们的工作特性进行了分析。应用自行封装的光纤光栅传感器,监测了碳纤维复合材料固化过程中材料内部的温度变化和收缩应变。实验结果表明,使用光纤光栅传感器对复合材料固化期收缩应变监测时需进行温度补偿。光纤光栅传感器为复合材料固化监测及分析提供了一种新的工具,是监测复合材料固化过程的理想器件。
Abstract
Basic principle and merits of fiber Bragg grating (FBG) are introduced. A novelty strain sensor and a temperature sensor with FBG technology are presented. Theoretical and experimental analyses of FBG sensor are implemented. The variations of temperature and strain profiles during curing process are experimentally explored by embedded FBG sensors. However,the thermal drift of FBG strain sensor should be considered during the strain measurement. The experimental results indicate that application of FBG sensor on monitoring the composite in curing process is suitable.
