摘要
采用热氧化处理法对碳纤维表面进行改性,研究了不同温度处理后碳纤维的表面刻蚀情况及官能团变化情况。通过0.5%亚甲基蓝溶液中的爬升浸润性高度,分析了碳纤维的表面变化情况;对碳纤维复丝进行拉伸实验,表征了环氧树脂与改性后碳纤维的界面结合情况。用SEM、EDS和XRD对改性后碳纤维化学镀铜表面官能团变化进行了定量研究。实验结果表明,热氧化处理改性碳纤维的合适条件为300℃和1小时,改性后碳纤维表面可有效实现化学镀铜。
In this paper, the surface modifications of carbon fiber including the surface etching and the functional group changes after the treatment in different temperatures were investigated by thermal oxidation treatment method. The surface changes of carbon fiber were analyzed by the invasive height in 0.5% methylene blue solution;the interface between carbon fiber and epoxy resin was characterized by the tensile tests of multifilament carbon fibers. The surface functional groups after the electmless copper plating were quantitatively researched by SEM, EDS and XRD. The experimental results show that the thermal oxidation treatment conditions of 300℃ and 1 hour are suitable,the electroless copper plating on carbon fiber are effectively achieved after the surface modification.
