摘要 作为一种新型的先纤实时传感系统,长周期光纤光栅(Long-period Fiber Grating,LPFG)传感器受到了越来越多的关注,采用长周期光纤光栅(Long-period Fiber Grating,LPFG)传感器监测树脂传递模型(Resin Transfer Molding,RTM)工艺的流动前沿,研究了各种工艺条件对LPFG损耗波峰的影响, 探讨了LPFG在RTM工艺中的应用情况。 The long-period grating technology, a new fiber optic real-time sensor system, is developed to monitor flow front progression. The sensor operation and characterization under various process conditions are discussed in detail. The experiment results show that LPFG sensors are robust and reliable to detect the arrival of resin at pre-selected locations in structures with low-medium fiber volume fraction while limited at different depths in structures with high fiber volume fraction.
