摘　　要：针对本实验中使用的改性双马树脂,采用DSC测试分析了树脂体系的固化工艺制度。通过树脂流变性能测试选取了100℃、110℃和120℃作为3个加压时机,研究了加压时机对改性双马树脂单向复合材料层板力学性能的影响。结果显示,随着加压温度的降低,单向复合材料的力学性能略有提高;不同力学性能对加压时机的敏感程度不同,本实验中相对于压缩性能、弯曲性能和层间剪切性能,拉伸性能对加压时机的变化更为敏感。研究结果对于进一步研究改性双马树脂的工艺特性及其碳纤维增强复合材料的力学性能提供了参考。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.
