摘　　要：纤维增强树脂基复合材料的成型质量受树脂流动、固化反应、热应力等诸多因素影响,控制难度大,工艺优化复杂,将各类传感器置于复合材料内部或外部进行在线监测能获得反映上述变化的材料及工艺特征参量,为工艺参数的调整、优化以及成型过程的研究提供重要依据。本文综述了航空航天领域常用的成型工艺在线监测方法,包括光纤光栅法、碳纳米管传感器法、树脂压力在线监测法、薄膜压力传感器法、介电分析法等,可实现成型过程中温度、应变、压力、树脂流动前锋、树脂黏度及固化状态等信息的获取,进而实现成型缺陷消除和工艺优化;探讨了在线监测技术与数字化技术的结合方式,并指出了目前在线监测技术的存在问题和发展方向。Processing quality of fiber reinforced resin matrix composites is influenced by many factors,such as resin impregnation and flow,curing reaction,thermal and residual stresses.These processes are typically carried out within enclosed chambers or molds,which are complicated to control and optimize.Placing various sensors inside or outside composite parts for online-monitoring can obtain characteristic parameters of material and molding process that reflect the above physical and chemical changes.It can provide an important basis for the adjustment and optimization of process parameters and the research of composite molding process.This article aims to summarize onlinemonitoring methods for composite processing,which are commonly used in aerospace field,including fiber grating method,carbon nanotube sensor method,resin pressure online monitoring method,thin film pressure sensor method and dielectric analysis method.The implementation of these methods enables to obtain important information about molding process,such as temperature,strain,pressure,resin flow front,resin viscosity,and curing state.The acquisition of these information is of importance for eliminating molding defects and optimizing manufacturing processes.In addition,this article also discusses the combination of online-monitoring and digital technologies,and the existing problems and development trend of online-monitoring technology are pointed out.
