However a variety of materials like wood, steel, aluminum, fiber materials, carbon fiber, aromatic polyamides are available for designing wind blades. Among these materials suitable one is selected based on their properties and performance. Suresh Talur et al (2015), presented detailed studies on material selection for wind blades, this study includes comparative analysis on giving ranking and performance percentage for different materials Aluminum 7020 alloy is ranked 3rd whereas the other materials like stainless steel and polycarbonate sheet are in 2nd and 1st
respectively. Another study on material selection by K. Suresh Babu et. al. (2006) describes which material is suitable on the basis of our requirement. In the present paper, for fabricating the laboratory testing model, aluminum material is used. Aluminum is in ductile nature having a low fatigue levels. Apart from this aluminum is having a low
