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。

Abstract: 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.
