摘要
采用阳极氧化法对碳纤维三维织物进行了表面处理。通过复合材料的界面强度、抗冲击性能和抗压性能 ,研究了阳极氧化处理工艺参数对碳纤维三维织物复合材料性能的影响。实验结果表明该方法不仅能对三维织物表层的碳纤维进行表面改性 ,而且能深入织物内部 ,实现对碳纤维三维织物的均一化处理 ,从而使碳纤维三维织物 /酚醛复合材料的界面强度均得到大幅度提高 ,复合材的整体性能得到改善。
The anodic oxidation surface treatment of carbon fibers in 3\|D braided preform was studied. The effects of treatment parameters on the properties of 3\|D braided carbon fibers composites were examined in terms of interfacial strength, impact strength and compressive strength, and the fracture of the composites was characterized by SEM. The results indicate the method can treat the surface of carbon fibers not only in the outer layer region but also in the inner region of the braided materials. Moreover, the interfacial strength of the 3\|D braided carbon fiber/phenolic resin has been improved obviously and the integrated property of composites has also been improved.
