介绍了碳纤维化学镀工艺流程以及预处理的步骤,采用无贵金属胶体铜一步活化替代传统的两步活化;并研究了时间、温度、振动频率对化学镀反应的影响.扫描电镜观察表面形貌,增重率表示镀铜量,冷热循环法检测镀层结合强度,得到最佳工艺参数.结果表明,胶体铜一步活化碳纤维,可得到均匀、完整、结合力强的镀层,步骤简单、成本低廉. The process of carbon fiber electroless plating and the steps of pretreatment were introduced. The non-precious metal colloid copper was used to replace the traditional two-step activation. The effects of time, temperature and vibration frequency on the electroless plating reaction were also studied. The surface morphology, The results showed that the colloidal copper could activate the carbon fiber in one step to obtain a uniform, complete and strong binding layer with simple steps and low cost.
