| 摘 要： | 采用纳米SiC和环氧树脂(EP)对双酚A型氰酸酯树脂(CE)进行改性。研究了不同含量的纳米SiC对CE/EP/纳米SiC复合体系反应性及CE/EP/纳米SiC复合材料力学性能的影响,采用透射电子显微镜表征了材料的微观形貌,利用差示扫描量热法研究了固化树脂的热性能。结果表明,纳米SiC对CE/EP/纳米SiC复合体系具有明显的催化作用,并且能使复合材料的冲击强度提高123.62%,弯曲强度提高140.29%,有效发挥其增强增韧作用,还能很好地保持复合材料的耐热性能。

| Abstract: | Cyanate resins were modified by nano-SiC and epoxy resin. The effects of different content of nano-SiC on the reaction mechanism and the mechanical properties were investigated. The morphology was investigated by transmission scanning electron, and the thermal property was investigated by differential scanning calorimetry. The results indicated that nano-SiC could catalyze cyanate obviously. The impact strength and the flexural strength of cyanate/nano-SiC composites were increased by 223.62% and 240.29% respectively, compared with cyanate composites without nano-SiC. The thermal property could be maintained well by addition of nano-SiC. |
