摘要: 研究了混合后晾置时间、固化程度、混合比例和胶层厚度对风电叶片用环氧结构胶粘接性能的影响。采用拉伸剪切强度和等效剥离强度对粘接性能进行表征。研究表明:结构胶混合后晾置90 min再进行粘接,粘接强度最高;Tg达到60 ℃后,粘接强度处于稳定状态;在正负5%的配比变化范围内,粘接性能稳定;胶层厚度增加,剪切强度呈线性下降趋势,而剥离性能基本稳定。此项研究为风电叶片合模工艺优化提供了技术基础。

Abstract: This paper studies the effect of waiting time after mixture, curing degree, mixture ratio and the thickness of adhesive on bonding performance of epoxy structural adhesive for the wind turbine blades. The bonding performance of epoxy structural adhesive were characterized by tensile shear strength and equivalent peel strength. The results show that structural adhesive mixture with the waiting time of 90 min has the highest bonding strength. After glass transition temperature reaches 60 ℃, bonding strength is in a stable state. Within ±5% of the theoretical ratio of adhesive, the bonding performance of epoxy structural adhesive is stable. With the increase of the adhesive thickness, the shear strength shows a linear downward trend, while the peel performance is basically stable. The study provides technical basis for wind blade bonding process optimization.
