本文作者采用XPS,单丝模型,SEM和测定电阻率等方法研究了玻纤表面以A-151、A-186 KH550偶联剂处理后形成的界面层结构;介质在环氧/玻纤复合材料中的扩散系数;界面的粘结形貌等对复合材料耐蚀性能的影响。实验表明,既能与玻纤表面产生化学反应又能与环氧基体形成化学共价键的界面具有较高的界面粘结能,完善的界面粘结形貌,较低的介质扩散系数和良好的界面耐腐蚀性。
The authors used XPS, monofilament model, SEM and the determination of resistivity and other methods to study the glass fiber surface with A-151, A-186 KH550 coupling agent after the formation of the interface layer structure; medium in the epoxy / glass fiber composite material In the diffusion coefficient; interface morphology such as the corrosion resistance of composite materials. The experimental results show that the interface which can not only make chemical reaction with the glass fiber surface but also form chemical covalent bond with the epoxy matrix has higher interfacial bonding energy, perfect interfacial bonding morphology, lower medium diffusion coefficient and good Corrosion resistance of the interface.
