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KH560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,经KH560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/KH560复合材料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%。
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 of nano-SiC with KH-560 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 KH560 modified nano-SiC increased 86.26 % and 29.56 %, respectively, based on neat CE resin.
