The purpose of the present study is to design a micro scale composite wind turbine blade. The blade airfoil of FFA-W3-211 was selected to meet Korean weather condition. The skin-spar-foam sandwich type structure was adopted for improving buckling and vibration damping characteristics. The design loads were determined at wind speed of 25m/s, and the structural analysis was performed to confirm safety and stability from strength, buckling and natural frequency using the finite element analysis method. The prototype was manufactured using the hand-lay up method and it was experimentally tested using the three point concentrated loading method. In order to evaluate the design results, it was compared with experimental results. According to comparison results, the estimated results such as compressible stress, max tip deflection, natural frequency and buckling load factor were well agreed with the experimental results.
