Abstract Scope |
Wind turbine blades undergo damage during their service due to various reasons, such as damage due to erosion, bird collisions, lightning strikes, etc. which lead to high costs due to the downtime of wind blade repairs. To minimize blade downtime, there is a need for a time- and cost-effective repair process, which is highly variable and depends on the repair methods, repair geometry and environmental conditions among other aspects. Parts of the wind blades consist of sandwich composite material and balsa wood core. The goal of this study is to implement the process model developed in-house using finite element methods to different repair geometries to investigate the effect of balsa wood thickness in a repair laminate. The appropriate boundary conditions for a hot plate as a heat source have been determined. Finally, the repairs simulated using process modeling are validated against experimental repairs performed in the lab. This study will enhance the library of types of wind turbine repairs performed using process modeling and will serve as a stepping stone to the development of an optimization tool for the repair of any damaged wind turbines. |
