A ternary blend resin(BFM) was prepared by diaminodiphenylmethane-based-benzoxazine(B), epoxy F-51 and imidazole. The curing kinetics of BFM resin was investigated by non-isothermal differential scanning calorimetry (DSC) according to Kissinger,Ozawa, Friedman and Flynn-Wall-Ozawa methods. There were two strong exothermal peaks in the DSC thermograms of BFM resin, which were corresponding to two kinds of curing reactions with the apparent activation energy of 85.05 kJ/mol and 137.3 kJ/mol, respectively. The reaction orders of the two kinds of reaction were 0.8 and 1.6, respectively. Furthermore, the curing process of BFM resin was established from a method proposed to determine the curing time，based on its curing reaction and kinetic parameters.
