The method and system for real-time monitoring of the molding process of carbon fiber epoxy composites by optical fiber are studied. The change of viscosity and the curing process of the resin can be reflected by measuring the change of the refractive index of the resin during the forming process of the composite material. An optical fiber sensing probe designed for curing monitoring is designed to greatly reduce the influence of defects in the resin on the measurement and is easy to use. Developed a computer real-time monitoring system of composite material forming process. The system was used in the press on carbon fiber epoxy composite material molding process of real-time monitoring experiments. The experimental results show that the system work is stable and reliable, the test results reflect the curing process of the resin.
