Abstract: To analyze and study the process parameters of bismaleimide resin with pultrusion process，the curing reaction kinetics of the bismaleimide resin BMI-QC130 was studied with DSC analysis. The curing degree prediction model was established，and the predicted values are well coincident with the test values. The viscosity prediction model was established by the dual-Arrhenius equation to predict the resin rheological behavior of the BMI resin system，which has a good prediction precision when the temperature is lower than 120℃. Based on the analysis results of the curing degree model and the viscosity model，the pultrusion process parameters of the bismaleimide resin BMI-QC130 are determined：the resin is melted at 95℃ in the resin bath，precured at 200℃ in pultrusion mould and postcured at 280℃ in hot tunnel. The carbon fiber reinforced BMI-QC130 composite samples are successfully manufactured with the pultrusion process under such process conditions.
