【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]:The importance of adhesive in wind turbine blade is briefly described, and epoxy adhesive is mostly used in wind turbine blade. The glass transition temperature, shear fatigue and creep properties of domestic adhesives and imported adhesives were compared and tested from the point of view of blade design requirements, and the adhesion cross-sections of the two kinds of adhesives were scanned. The simple analysis shows that the adhesive section of the imported adhesive is a typical ductile fracture, and the adhesive section of the domestic adhesive presents toughness and brittleness, and improves the toughness of the adhesive. Improving the compatibility of toughened system and epoxy resin matrix is an urgent problem for domestic adhesives.
