摘　　要：研究了纳米SiO2含量对苯并恶嗪树脂(BOZ)/双马来酰亚胺(BMI)/双酚A型氰酸酯(BADCy)/纳米SiO2复合材料力学性能、热性能和吸水性能的影响。结果表明,当纳米SiO2质量分数为3%时,BOZ/BMI/BADCy/纳米SiO2复合材料具有较高的强度和良好的韧性,其缺口冲击强度和弯曲强度比BOZ/BMI/BADCy共聚物分别提高了11.6%和8.5%;同时,纳米SiO2质量分数为3%时BOZ/BMI/BADCy/纳米SiO2复合材料具有优异的耐热性,其初始热分解温度和最大热分解温度分别为343.2℃和430.3℃。The effects of the content of nano-SiO2 on mechanical properties, thermal properties and water-absorbing properties of BOZ / BMI / BADCy / nano-SiO： composites were investigated. When the mass fraction of nano-SiO2 was 3%, BOZ / BMI / BADCy / nano-SiO2 composites had higher strength and better toughness, compared to BOZ / BMI / BADCy copolymers, the notch impact strength and flexural strength of BOZ / BMI / BADCy / nano-SiO2 composites were improved by 11.6% and 8.5% respectively. Simultaneously, when the mass fraction of nano-SiO2 was 3%, BOZ / BMI / BADCy / nano-SiO2 composites had excellent heat resistance, the initial degradation temperature and the maximum degradation temperature were 343.2 ℃ and 430.3℃ respectively.
