Effect of Material Blade Types on Performance a Small Wind Turbine

The very growth in wind energy technology in the last 20 years has led to presence of many wind turbines around the world in different shapes and designs and even in the type of materials they are made of Wind energy can offer a promising source of environmentally safe renewable energy and clean without any emissions during operation, this paper highlights many types of materials can used in made the structural of wind turbine blades, to find the best performance and suitable material for wind turbine blade.  Designing reliable wind turbine blades materials under various loading and environmental conditions. the four materials are using in this study (woood_yew, E_glassfibers blastic_asa and aluminum 1200) the result after doing simulations for four types of materials using for design blades of small wind turbine noted the better the efficiency and performance of the wind turbine at the higher the Betz number, Light materials, such as glassfibers and aluminum, require less energy resistant to weather conditions such as humidity and corrosion, resulting in lower mechanical losses. Unlike heavier materials, such as wood and plastic, which require a high coefficient exposed to weather conditions, especially humidity, which causes faster turbine damage.
