用表面电聚合方法处理碳纤维，能i.1显著地改善碳纤维与环城jt体两相之间的结合力，使复合材料的剪切强度提高到800kg/cm2以上，湿态常温剪切强变、干盆高温剪切强度以及冲击强变都获得了不同程度的提高。该方法有希望通过改变聚合物层的结构以及控制聚合物层的厚度而使复合材料获得良好的综合力学改能.扫描电镜、红外光谱和电化学分析方法用于分析该实验现象。
Abstract
Surface treatment for carbon fibres by electropolymerization can enhance the bond between the carbon fibres and the resin.The short beam interlaminar shear strength of the composite can be increased to above 800kg/cm2.The impact strength and the shear strength in net and at the temperature of 125℃ can be improved, This method promises to obtain the comprehensive excellent properties of the composite by controlling the structure and the thickness of the polymer electropolymerized,SEM, the infrared spectrascopy and the voltammetry were used in the experiment.
