设计了两种新型光纤传感器，一种是通过测量光纤末端近场模斑谱反映光纤埋置周围树脂折射率的变化，另一种是采用光纤微弯衰减方法测量复合材料固化中铺层被压缩的进程。利用这两种传感器进行了复合材料固化监测实验，结果表明，发现光纤模斑传感器的信号可以准确反映树脂基体的粘度的变化历程，光纤微弯传感器的信号可以反映铺层被压缩的过程，监测这两个关键的参数变量不但有利于操作工艺的优化，而且为建立复合材料固化过程的智能化在线监控系统奠定了基础
Two kinds of new optical fiber sensors are designed. One is to measure the refractive index change of the resin near the optical fiber by measuring the near-field speckle spectrum at the optical fiber end, and the other is to measure the compressibility The process. The results show that the signal of fiber optic plaque sensor can accurately reflect the change course of the viscosity of resin matrix. The signal of fiber microbend sensor can reflect the course of ply compression, These two key parameter variables not only help optimize the operation process, but also lay the foundation for establishing an intelligent on-line monitoring system for the curing process of composite materials
