The use of optical fibers to monitor the curing process of polymer matrix composites is an attempt to introduce smart materials and structures into the production process of traditional materials, which will benefit the development of traditional materials. In this paper, the principle and feasibility of optical fiber monitoring composite material forming process are described. Two kinds of optical fiber sensors based on phase modulation and intensity modulation are respectively developed to monitor the internal changes during the curing process of the composite material. The monitoring results are more sensitive and accurate The development of optical fiber intelligent technology has opened up a new direction
