According to the curing reaction behavior of T800 / epoxy composites under microwave curing process, the non-isothermal differential scanning calorimetry (DSC) method was used to study the curing reaction exothermic process of T800 / epoxy composites. Based on the Kamal dynamic model, the particle swarm global optimization algorithm was used to fit the solidification reaction kinetics equation of T800 / epoxy resin composite with pure microwave curing process and high-pressure microwave curing process. The experimental results show that the equation can be well Describe the kinetics of microwave curing reaction of T800 / epoxy composites. The effects of different curing methods on the curing kinetics of T800 / epoxy composites were systematically studied. The results show that compared with the traditional thermal curing process, the microwave curing process can effectively increase the curing reaction rate and the activation energy of the curing reaction of the T800 / epoxy composites. Meanwhile, the curing pressure is introduced into the T800 / epoxy composites Curing reaction has a certain role in promoting.
