摘　　要：界面粘结的性能直接影响复合材料综合性能，复合材料的破坏往往是界面产生应力集中先破坏，因而对于增强体的表面处理是影响复合材料能否发挥最优性能的关键。涤纶帘子线（尤其高模低缩涤纶帘线）被广泛用于轿车轮胎增强体，但由于其界面的粘结强度制约了涤纶帘线的发展，有必要探索性能优良的方法来改善界面的粘结强度。在传统的RFL（间苯二酚-甲醛-胶乳）胶粘剂的基础上，用环氧树脂预浸胶来对涤纶帘线进行表面预处理，用H-test来表征粘结强度的优劣，以及模拟轮胎在运动过程中发热测定粘结强度与温度的依赖关系，同时用红外-拉曼光谱对胶粘剂在界面发生的反应及电子显微镜来探讨界面破坏形貌对粘结强度的影响；并且对尼龙与涤纶帘线与橡胶粘合的一些性能进行了对比。The interfacial adhesion strength has very important effect on comprehensive performance of composite materials. Because of stress concentration, fracture usually happens at the interface of composite materials. In order to exert excellent performance of composite materials, the process of interfacial treatment plays an important role in composite materials performances. PET cord （especially HMLS） is widely used as reinforcing materials in car industry. For low interfacial adhesion strength, it is very urgent to explore right interfacial treatment methods.In this paper, adhesive activation of PET cord based on the traditional RFL adhesive is accomplished by predipping in water-solubility epoxy resin with different curing reagents. PET/cord interfacial strength is characterized by H-test method. The adhesion strength depending on temperature is also discussed by simulating the running tire. The chemical reactions of adhesives on PET cord are studied. Meanwhile the effect of interfacial shape on adhesion is discussed by SEM. And the adhesion performances between nylon and PET cord with rubber are compared..
