摘要： 采用模塑成型法制备氰酸酯树脂(CE)/纳米SiC复合材料，通过冲击强度和弯曲强度测试，分别考察了纳米SiC及其经偶联剂KH-560表面处理后对CE/纳米SiC复合材料力学性能的影响，并通过理论分析探讨了其作用机理。结果表明，纳米SiC能够有效地改善复合材料的力学性能，而经KH-560表面处理的纳米SiC能进一步提高复合材料的冲击强度和弯曲强度；当纳米SiC含量为1 %时，CE/纳米SiC和CE/纳米SiC/KH-560复合体系的冲击强度分别提高了73.66 %和86.26 %，弯曲强度分别提高了20.85 %和29.56 %。

Abstract: The cyanate ester resin (CE)/nano-SiC composites were prepared by moulding method. Influences of nano-SiC and its surface treatment on the static mechanical properties of CE were characterized through impact and flexural strengths. The reinforcement mechanism was discussed. It indicated that nano-SiC efficiently improved the static mechanical properties of CE, and the surface treatment with KH-560 of nano-SiC further improved the impact and flexural strengths. When the content of nano-SiC was 1 %, the impact and flexural strengths of the composites containing untreated nano-SiC increased 73.66% and 20.85%, those containing KH-560 modified nano-SiC increased 86.26% and 29.56%, respectively, based on neat CE resin.

Key words: cyanate ester resin, nano-SiC, mechanical properties, modified mechanism
