Application of electrochemical methods to corrosion resistance evaluation for carbon fiber/epoxy composites

摘要

摘要: 用循环伏安曲线和交流阻抗谱测试技术研究了不同溶液浸泡对复合材料性能的影响,探讨了电化学表征参数与复合材料腐蚀程度之间的相关性.实验结果显示,随着浸泡时间的延长,试样的反应电阻逐渐减小,双电层电容逐渐增大,并且浸泡于酸性探针和碱性探针溶液中的试样的电化学参数比浸泡于中性探针溶液中的试样的电化学参数变化幅度更大.实验结果表明利用电化学参数的变化可以反映碳纤维增强环氧树脂基复合材料的腐蚀程度,即可以用阻抗值和电流值的大小变化表征复合材料的耐蚀性.

Abstract: The influence of different kinds of solution immersion on the properties of carbon fiber reinforced plastics was studied by means of cyclic voltammetry curves (CV) and electrochemical impedance spectroscopy (EIS). The relationship between electrochemical parameters and corrosion degradation of composites was discussed. Results show that the reaction resistance decreases and double layer capacitance increases with the increase of immersion time. The electrochemical parameters changes obtained from the acidic and alkaline probe solutions are more obviously than those obtained from the neutral probe solutions. Results indicate that the change of electrochemical parameters can reflect the corrosion degradation of composites, and electrochemical parameters can be used to evaluate the corrosion resistance of carbon fiber reinforced epoxy composites.
