| 摘 要： | 采用双马来酰亚胺(BMI)改性酚醛型环氧树脂(F-51)/芳香胺(DAMI)固化体系。采用DSC,TGA和TMA等仪器考察BMI含量对改性体系的固化行为、力学性能及热稳定性的影响,并用扫描电镜(SEM)研究材料断面的形态结构。结果表明,随着体系中BMI比例的增加,体系固化放热峰向高温区移动,总反应热减小,BMI的加入可以提高材料的力学性能和热稳定性,改性后材料断裂面的形态呈现韧性断裂特征。

| Abstract: | The system of phenol type epoxy resin(F-51) /amine(DAMI) modified by bismaleimide(BMI) were studied.The cured materials were characterized using differential scanning calorimetry(DSC),thermogravimetric analysis(TGA) and thermomechanical analysis(TMA).DSC thermograms showed the BMI improved the peak maximum temperatures with reduction in the total energy of heat source.Thermal studies indicated that BMI enhanced the thermal stability.The mechanical properties were investigated with GB standards.The results showed that the introduction of BMI into epoxy resin improved the mechanical properties.SEM observation of the fracture of the tensile specimen showed that the toughened fracture characters were obviously appeared for the blends. |
