Abstract Scope |
Efficient structural repair of wind turbine blades is essential to reducing the Levelized Cost of Energy (LCOE) for wind energy. Repairs carried out up-tower are sensitive to environmental conditions whose effects on the material properties during processing need to be accounted for to accurately predict the repair outcome. This study investigates the effect of moisture content from environmental exposure on the cure kinetics of a hand-lamination epoxy-amine resin system used in wind turbine blade repair. An experimentally validated finite element tool is utilized to simulate a wind blade repair and predict the cure evolution and temperature distribution within the repair patch as a function of the absorbed moisture content and repair geometry. A parametric study is proposed to determine optimal repair conditions in order to minimize the repair time while maintaining a homogenous cure and temperature distribution within the repair patch. Finally, a techno-economic model is introduced to assess the impact of various repair parameters on the LCOE. |
