| 摘 要： | 简述了胶粘剂在风电叶片中的重要性,风电叶片大多采用环氧胶粘剂。从叶片的设计需求角度,对比测试了国产胶粘剂和进口胶粘剂的玻璃化转变温度、剪切疲劳和蠕变性能,并对两种胶粘剂的粘接断面进行形貌扫描,简单分析得出:进口胶粘剂的粘接断面是比较典型的韧性断裂,国产胶粘剂的粘接断面呈现韧性和脆性结合体;提高胶粘剂的韧性,并不断改良增韧体系和环氧树脂基体的相容性是国产胶粘剂亟待解决的问题。

| Abstract: | Importance of adhesive in blade was described briefly in this paper.Epoxy adhesive is commonly applied in rotor blade.The glass transition temperature,shear fatigue and creep performance of abroad and domestic kind were tested according to design requirement.The result was that import kind fracture area is typical toughness,while the domestic kind is combination toughness and brittleness according to SEM.It is very urgent for domestic kind adhesive to improve the toughness of adhesive and compatibility. |
