Abstract: The non-isothermal curing kinetics of bismaleimide/benzoxazine/grapheme (BMI/BOZ/GNS) systems was studied by using differential scanning calorimetry (DSC). The curing kinetics parameters were obtained using Kissinger and Ozawa equations. The effect of GNS on the mechanical performances of BMI/BOZ/GNS system was investigated. The tensile properties of BMI/BOZ/GNS system increased firstly and then decreased with increasing GNS content. When the content of GNS was 0.15 wt %, the mechanical properties of BMI/BOZ/GNS system were the best.

Key words: bismaleimide, benzoxazine resin, graphene, cure reaction kinetics, mechanical property
