摘要(Abstract)：
采用KH550硅烷偶联剂处理芳纶,将处理温度、时间、硅烷偶联剂的质量分数作为3个因素进行分析,通过单因素分析法确定每个因素对处理前后芳纶与树脂的界面剪切强度的影响,结合扫描电镜观察处理前后纤维的表面结构变化,得到最佳处理的工艺为:处理时间9 h、温度45℃、硅烷偶联剂的质量分数为25%。
Aramid fiber was modified with silane coupling agent KH550. The treatment temperature, time, concentration of the silane coupling agent were analyzed as three factors. Each of these factors was determined by the single factor analysis before and after treatment, combined with the influence of the interfacial shear strength of aramid fiber and resin, fiber surface structure changes observed before and after treatment with scanning electron microscope, the optimal treatment processes were: time 9 h, temperature 45 ℃, concentration of silane coupling agent 25%.
