Abstract: 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 online-monitoring 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.
