摘要
本工作借助偏光显微镜,扫描电子显微镜和热分析方法(DSC,TGA)研究了尼龙66盐与碳纤维复合-固态缩聚反应历程及纤维-树脂之间的界面效应。发现对尼龙66盐的“原位固态缩聚”存有如碳纤维表面的成核结晶和催化效应之类的界面效应。讨论了碳纤维的界面效应对尼龙66基体的外延结晶和熔融行为及其热氧化稳定作用的影响。
The mechanism of the solid-state polycondensation of nylon-66 with carbon fiber composites and effects of the interface between the fiber and matrix were studied by using polarized light microscopy,SEM and thermal analysis methods(DSC,TGA).It was found,that some inter-facial effects such as fiber surface nucleating the crystallization and catalytic effect for the“in situ solid-state polycondensation”of nylon-66 salt were existed.The interfacial effects of the carbon fiber on the epitaxial crystallization and melt behaviour of nylon-66 matrix as well as on the stabilization for thermal oxidation of nylon-66 matrix have been discussed.
