Wet Flexural Fatigue Behaviour of Tidal Turbine Blade Composite Materials

AK1000_Body_430A paper find on the web about fatigue of Tidal Turbine Blade Composite Materials.

This has led to the emergence of tidal turbine designs often inspired from earlier developments in the wind turbine industry.  Composite materials including Glass fibre reinforced polymers (GFRP) are a low-cost, low weight and corrosion resistant material for this application. Cyclic loading due to tidal flow and wave conditions is a common characteristic of tidal turbine devices and the good fatigue performance of composite materials means they are widely used, however limited information are available to predict material behaviour under coupled environmental and cyclic loading. This problem is addressed in this paper, by introducing a methodology for prediction of the fatigue behaviour of composite tidal turbine blades.
