Kinetics modeling of carbon fiber T800/epoxy resin composites based on microwave curing process

In order to investigate the curing behavior of carbon fiber (T800)/epoxy matrix composites under microwave curing process, the exothermal process of curing reaction of T800/epoxy resin matrix composites was studied by nonisothermal differential scanning calorimetry (DSC). Based on Kamal dynamics model, T800/epoxy resin composite reaction kinetics equation of microwave curing technology and high-pressure microwave curing process was obtained by fitting the particle swarm optimization algorithm. And the effect of different curing methods on the curing kinetics of T800/epoxy resin composite was systematically compared. The experimental results show that the equation can well describe the microwave curing behavior of T800/epoxy resin composites. The results show that compared with the traditional thermal curing process, the microwave curing process can effectively improve the curing rate of T800/epoxy resin composite and reduce the activation energy of the curing reaction, while the introduction of curing pressure to the curing reaction of T800/epoxy resin composite have a certain role in promoting.
