Abstract

The curing kinetics of JF-45 and E-51 epoxy resins modified bisphenol A cyanate ester resin was studied by differential scanning calorimetry( DSC). Curing reaction kinetic parameters were obtained arrording to Kissinger equation,Crane equation and Arrhenius equation. The cure kinetic model of cyanate ester system was established. The results showed that the modified cyanate ester system had two exothermic peaks during the curing process. The apparent activation energy,pre-exponential(A1) ,reaction order factor and curing reaction constant (K1) of the first exothermic peak were 75. 192 kJ/mol,7. 321 × 107,0. 901 and 7. 321 × 107exp( -9044. 022/ T) ,respectively. The corresponding data of the second exothermic peak were 83. 073 kJ/mol,4. 986 × 107,0. 911,and 4. 986 × 107exp( -9 991. 941 /T) ,respectively.
