THE STUDY OF DIFFERENCE BETWEEN REPAIRING TECHNIQUES OF ADHESIVELY BONDING AND VARI

Abstract

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%.

Key words: wind turbine blades, repairing, adhesive bonding, VARI
