Abstract: Differential scanning calorimetry (DSC) was adopted to analyze the curing process of the modified bismaleimide resin system. The resin viscosity was tested and analyzed, and then three different temperature values, 100℃,110℃ and 120℃, were selected to investigate the effect of pressure applying moment on mechanical properties. The results show that the mechanical properties get a little better with the lower temperature of pressure applying moment. Different mechanical property shows different sensitivities to the change of pressure applying moment and tensile properties are more sensitive than compressive properties, flexural properties and interlaminar shear properties in this research. This research provides important reference value for further study on process properties of modified bismaleimide resin system and mechanical properties of carbon fiber reinforced modified bismaleimide composite material.
