Abstract
Offshore wind energy has high potential to generate clean energy. Wind turbine sizes are increasing and reaching above 200 m in diameter. The high velocity blade tips interact with rain droplets which cause erosion damage over time. To mitigate erosion damage, protective materials are applied to the leading edge. In order to effectively design these protection systems, the stress state in the layered material system has to be understood. The current work discusses a numerical model to predict the stress field in a co-bonded hybrid thermoplastic/thermoset layered composite system. It studies the influence of layer thickness, interphase thickness, droplet diameter and LEP material properties on the stress state in the hybrid composite coating system. It was found that the design of the system significantly influences the dynamic stress state in the layered system and as a result, the performance of these systems as protection layers for wind turbine blades gets diminished.
