采用液相氧化法对PAN系碳纤维进行了表面处理,研究了不同条件下,碳纤维表面状态对C/C复合材料中纤维和基体结合程度的影响规律,并通过扫描电镜的观察,分析了影响因素与结合状态的关系。
The PAN-based carbon fibers were surface-treated by liquid-phase oxidation method. The influence of the surface condition of carbon fibers on the bond between fiber and matrix in C / C composites was studied under different conditions. The influence factors Relationship with the combined state.
