摘　　要：风电叶片合模粘接工序中缺胶问题一直备受关注,修复材料的性能直接影响叶片修复质量,为此选择2种胶黏剂,对比了两者的工艺基本性能数据和力学性能。胶黏剂1可适合用于风电叶片制造成型合模粘接,也可用于叶片胶黏剂缺陷修复;胶黏剂2适合用于叶片胶黏剂缺陷修复,同时在修复效率和操作条件上优于胶黏剂1。然后通过模拟一种叶片缺胶的修复方式,分别采用胶黏剂1、胶黏剂2对不同缺胶量的玻璃钢试件粘接界面进行拉伸剪切性能测试。研究结果表明,2种不同体系的胶黏剂各性能差异较小,均可满足叶片设计和工艺要求;随粘接面缺胶量增大(20%、40%、60%),试样拉伸剪切强度呈下降趋势;缺胶处使用胶黏剂1进行修补后可使拉伸剪切强度恢复,使用胶黏剂2修补后试样拉伸剪切强度低于胶黏剂1修补。因此,在缺胶处修补时采用同一体系胶黏剂修补的效果较好,更利于保证叶片修复后的质量和性能。The lack of glue in the mold clamping bonding process of wind turbine blades has always been a concern.The properties of repair materials directly affect the quality of blade repair.Two kinds of adhesives were selected to compare their basic performance data and mechanical properties.Adhesive 1 can be used for mold clamping bonding of wind turbine blades,but also for repairing blade adhesive defects;Adhesive 2 is suitable for repairing blade adhesive defects,and is superior to adhesive 2 in terms of repair efficiency and operating conditions.By simulating a repair method of glue-lacking blade,the tensile shear properties of the bonding interface of FRP specimens with different glue-lacking blade were tested with adhesive 1 and adhesive 2,respectively.The results show that there is little difference between the properties of the two adhesives,which can meet the requirements of blade design and process.The tensile shear strength of the specimens decreases with the increase of the glue-lacking blade on the bonding surface(20%,40%and 60%).After repairing with adhesive 1,the tensile shear strength of the glue-lacking area can be restored.The tensile shear strength of the specimen repaired with adhesive 2 is lower than that repaired with adhesive 1.Therefore,it is better to use the same system of adhesives to repair the glue-lacking area,which is more conducive to ensuring the quality and performance of the repaired blade.
