摘要
利用阳极氧化法对碳纤维进行表面改性处理 ,研究了碳纤维处理前后表面化学组成 ,纤维复丝拉伸强度和复合材料的层间剪切强度 ( IL SS)。结果表明 ,经阳极氧化处理碳纤维表面的含氧、含氮极性官能团数目增加 ,纤维复丝拉伸强度有所下降 ,复合材料的 ILSS值提高。同时通过实验结果分析 ,阐明阳极氧化处理使复合材料界面性能改善的机理。
WT10.25BZ]Anodic oxidation treatment method was used to modify the surface of carbon fibers The chemical composition of carbon fibers surface, the tensile strength of filaments and the interlaminar shear strength (ILSS) were studied respectively The results indicate the number of polar functional groups on the carbon fiber surface and the ILSS of the composites are increased, and the tensile strength of filaments is decreased in a certain scope Meanwhile the mechanism of the anodic oxidation treatment to improve the interfacial property of composites is obtained by analyzing the results
