Fiber optic is a new kind of information sensing material. Embedding fiber optic sensors into resin matrix composite materials to monitor the curing process is an important step in developing smart materials and structures in the production of traditional materials. This paper introduces the sensing of the molding of composites using fiber optics. The results illustrate the feasibility of the smart fiber optic composites system. Two sorts of fiber optic sensors based on phase modulation and strength modulation were used to monitor the composite during the curing process. They can sensitively and precisely monitor the composite curing process. This smart fiber optic sensing technology will be widely used in the future.
