For the safety and reliability of small size Wind-lens turbine, several experiments of mechanical properties of blade's material, Dicyclopentadiene was conducted. Vickers hardness was Hv =13.8 independent of load times and load magnitudes. Fatigue strength of the specimen contained some scale voids were quite low compared to the plain specimen contained no voids. Fatigue strength of notched specimens was lower than that of plain specimen. Non-propagating fatigue crack was not observed on this material. Fatigue crack growth property was obtained by three point bending fatigue test. The relationship between fatigue crack growth rate and the stress intensity factor range, ΔK, was obtained. Charpy impact absorption energy of Dicyclopentadiene was three times as that of ABS resin.
