Abstract:We have developed new polymeric systems based on the ternary mixture of typical benzoxazine mono
mers with a typical modification bismaleimide and epoxy resin. Non-isothermal differential scanning calorimetry (DSC)
was used to follow the curing reaction. The analyses showed that there are a exothermic reaction peak from 164℃ to
306℃ for the modification benzoxazine/ bismaleimide/ epoxy resin system and top of the peak is 240℃,which con
firmed main reaction of modification benzoxazine/ bismaleimide/ epoxy resin system. The curing process temperatures
such as gelation temperature (Tgel)= 151℃, curing temperature (Tp)= 224℃ and postcuring (Ttreat )= 295℃ were
acquired. The reaction energy of the modification benzoxazine/ bismaleimide/ epoxy resin system was 89. 5 kJ/ mol and
the reaction level is 0. 93 by using Kissinger and Crane equation. The cure kinetic model of the curing process based
on n order reaction equation was established,which was used for simulation of the curing reaction characteristics. Cu
ring technics is 180℃/1 h+200℃/2 h+230℃/2 h,post curing technics is 250℃/2 h.
