Influence of Moisture and Elevated Temperature on Fatigue Properties of WTS-3 Glassfibre Blade Material

摘要

Fatigue tests carried out on the wind turbine blade glass fibre/epoxy material in a controlled environment of 90% relative humidity and at the maximum design temperature 35 degrees C are presented. Comparisons with data obtained in laboratory air show about 15% reduction in fatigue limit due to environmental effects. The presented results are likely to be conservative since elimination will be more suppressed in the real wind turbine blades. (ERA citation 10:033622)
