    Abstract

    Quasi-static strengths and elastic constants were measured in three dimensions (3D) for a glass fiber reinforced polyester. The sample was extracted from a block of material discarded during the construction of a wind turbine blade. The properties were evaluated in tension, compression, and shear stress employing guidelines of ASTM standards when possible. In-plane results were compared to in-plane coupons. Instead, the measured out-of-plane properties were compared with similar materials taken from the literature. The elastic orthotropic model was verified comparing the symmetric coefficients of the compliance matrix. These coefficients did not show large differences in tension, whereas differences were large in compression and shear. The resulting in-plane strengths were smaller than in coupons.
