[0026] Taking the curing of epoxy resin-based composite materials (specifically using epoxy resin carbon fiber composite materials) as an example, it is known that the basic form of its chemical reaction kinetic equation is an autocatalytic model based on a phenomenological model, and its basic form is:
[0027]
[0028] In the present invention, the chemical reaction kinetic equation of curing the epoxy resin-based composite material under microwave heating is the same form of chemical reaction kinetic equation as that under conventional heating conditions. The inventors found that this equation is a strongly coupled differential equation about time t, curing degree α and temperature T. And T itself is a function of t, so in order to obtain the four parameters A, E, m, and n of the equation, it is only necessary to know the change relationship between α-t and T-t, which can be obtained by nonlinear fitting through the particle swarm algorithm. And then solve the microwave ...
