摘　　要：采用模塑成型法制备CE/nano-S iC复合材料,分别考察了3种偶联剂表面处理nano-S iC后对其静态力学性能的影响,用透射电子显微镜(TEM)表征了材料的微观结构和形貌特征。结果表明:3种偶联剂的改性效果次序为:KH-560<SCA-3<SEA-171;当nano-S iC含量为1.00%时,相对于纯CE的冲击强度和弯曲强度,SEA-171的提高率分别为95.06%和34.69%。The CE/nano-SiC composites were made by molding method. The effects of the static mechanical properties of the nano-SiC,which was treated with three different coupling agents on its surface,were investigated respectively. The influence could be seen through the microstructure and those section＇ s pictures,which were shown under a TEM. The results indicated that the descending order of the modified effects of these three coupling agents were SEA-171 ,SCA-3 and KH-560. Compared with the impact strength and the flexural strength of the pure CE, the relative increase rates of SEA-171 were respectively 95.06 % and 34. 69 % ,under the condition that the content of nano-SiC was 1.00 %.
