英文摘要：

Aeeording to chemical kinetics and thermodynamics, the kinetic equation of the curing reaction of bismaleimide in resin transfer molding processes was constructed, and the characteristics of the chemical calorific effect were analyzed, and then the numerical calculation expressions of the reactive calorific intensity and the released heat of curing reaction were deduced by means of the increment method. Finally, the complex evolutions of the released heat of curing reaction and the reactive calorific intensity of an example were simulated via the finite element method, and the influencing factors were discussed.
