INFLUENCE OF CF SURFACE GRAFTING ON THE INTERFACE PROPERTY OF CF/PI (PMR-15)

摘要

摘要: 通过冷等离子体连续表面接枝技术对CF进行表面处理,采用XPS对CF表面组成及特征基团变化进行分析。同时测定了CF/PMR-15层间剪切强度、拉伸强度和冲击强度,研究了表面接枝对CF/PMR-15界面强度和韧性的影响。

Abstract: In this paper, CF was treated by the surface continuous grafting technology of cold plasma. The changes of characteristic groups and surface feature of CF surface were analysed by means of XPS. The interlayer shear strength, tensile strength and impact strength of CF/PMR-15 were measured, and the influence of surface grafting on the interface strength and toughness of CF/PMR-15 was studied.
