摘要: 研究了纳米二氧化硅(SiO2)的含量对双马来酰亚胺(BMI)/环氧树脂(EP)/2,2′二烯丙基双酚A(DBA)/纳米SiO2复合材料的耐热性能、力学性能和吸水性能的影响。结果表明,当纳米SiO2的含量为2.0 %(质量分数,下同)时,BMI/EP/DBA/纳米SiO2复合材料具有较高的强度和良好的韧性,其拉伸强度、弯曲强度和缺口冲击强度比BMI/EP/DBA复合材料分别提高了22.8 %、39.0 %和37.8 %;同时,纳米SiO2含量为 2.0 %时,BMI/EP/DBA/纳米SiO2复合材料具有优异的耐热性,其玻璃化转变温度、初始热分解温度和最大热分解温度分别为204、 410、451 ℃。

Abstract: Effect of nanoSiO2 content on the mechanical properties, thermal behavior and waterabsorbing of BMI/EP/DBA/nanoSiO2 composites was investigated. When the mass fraction of nanoSiO2 content was 2 %, the composites had higher strength and better toughness, compared with BMI/EP/DBA copolymers, and their tensile strength, flexural and notch impact strengths were improved by 22.8 %, 39.0 %, and 37.8 %, respectively. When the mass fraction of nanoSiO2 content was 2 %, the composites had excellent heat resistance; the glass transition temperature, initial degradation temperature, and the maximum degradation temperature were 204, 410, and 451 ℃, respectively.
