| 摘 要： | 研究了一种用于定量监测环氧树脂固化度的自参考型的光纤折射率传感器.该传感器用于环氧树脂基复合材料的固化监测时,埋设于复合材料结构内不同部位的传感器能够自参考地定标,使得传感器的输出能够进行实时的比较,从而反映复合材料内部不同部位的固化程度之间的差异.用该传感器对环氧树脂的恒温固化过程进行了监测,测量结果与差示扫描量热法的测量结果进行了对比,验证了该传感器的自参考功能.，A self-referenced fiber-optic refractive index sensor is developed to measure quantitative cure extent of epoxy. In case the sensor is applied to in-situ cure monitoring of epoxy composites, each sensor embedded in different location within the structure is self-referenced and can be normalized to a common scale. Therefore, the real-time comparative of each sensor's output becomes possible and variations in the extent of cure at different locations can be monitored. The developed sensor was used to monitor the isothermal cure of an epoxy system. The output of the sensor was compared with the results of the differential scanning calorimetry (DSC). The self-referencing function of the sensor is confirmed.
