摘要(Abstract)：

采用丙酮和石油醚索氏提取的方法,进行了碳纤维表面涂层去除的研究工作。利用AFM、SEM和XPS对碳纤维表面形貌、微观结构以及元素含量进行分析,并对碳纤维及其环氧复合材料的性能进行了表征。结果表明:碳纤维经丙酮抽提24 h,石油醚再抽提24 h后,纤维表面的涂层已完全去除,单丝拉伸强度略有降低,降低幅度为2.31%,但碳纤维/环氧树脂复合材料的界面剪切强度增加4.10%,层间剪切强度增加3.49%,表明该涂层去除方法具有较好的实验效果。
The method of Soxhlet extraction by acetone and petroleum ether successiely removing the size was investigated.The surface topographies,microstructure and elements content of carbon fiber were characterized by atomic force microscope(AFM),scan electronic microscope(SEM) and X-ray photoelectron spectroscopy(XPS) respectively.It was found that the CF size was removed completely after extracted by acetone for another 24 h,then petroleum ester for 24 h.The results showed that monofilament tensile decreased by 2.31 %,IFSS increased by 4.10 %,ILSS increased by 3.49 %.
