摘要/Abstract

摘要： 风电叶片在运输、安装及服役过程中,可能产生某些原因导致的需要修补的损伤。本文针对修补损伤的挖补法,设计了一组实验,比较了预浸料胶接修补与真空灌注修补的工艺区别,以及修补件静态力学强度恢复率的差异,并对两种工艺修补效果的差异进行了讨论。结果表明,在静态力学性能方面,胶接修补的拉伸强度和层间剪切强度性能可达到初始的80%左右,真空灌注修补工艺的拉伸强度和剪切强度可恢复到90%以上。

Abstract: Because of some partly damage,there are many repairing works in the process of wind turbine blade's transportation,assembly and service. In this paper,two scarf patch repair techniques,adhesively bonding repair and VARI(vacuum assistant resin infusion) repair,are designed. And the differences between these two methods are discussed. The results show that,tensile strength and shear strength of adhesively bonding method can remain about 80% after repairing,and VARI method can reach above 90%.
