Abstract : A first step in assessing the fatigue properties of the WTS-3 wind turbine blade material has been undertaken. Hereby flat test specimens of filament-wound material have been used for the fatigue tests. Wohler-diagrams (SN-curves) have been produced both at purely tensile loading and at completely reversed loading. The results show, as expected, that compressive loads are detrimental, due to local fibre-buckling, resulting in a substantial lowering of the entire SN-curve. (AN)
