Optimization and Analysis of Improved Material for Windmill Blades

In recent years the wind turbine blade has been the subject of comprehensive study and research amongst all other components of the wind turbine. Our appetite for renewable energy from the wind turbine continues to increase; companies now focus on rotor blades which can go up to 80m in length. The blade material not only have to face large aerodynamic, inertial and fatigue loads but are now being designed to endure environmental effects such as Ultraviolet degradation of surface, accumulation of dust particles at sandy locations, ice accretion on blades in cold countries, insect collision on blades and moisture ingress. All this is considered to ensure that the blades complete its designated life span. Furthermore exponential increase in composite blade manufacturing is causing a substantial amount of unrecyclable material. All these issues raise challenges for wind blade material use, its capacity to solve above mentioned problems and also maintain its structural integrity. Properties and corrosion resistance have been achieved. Under optimum conditions, a maximum Young's modulus of over 80 GPa, a maximum hardness of 1.39 GPa, and maximum wear resistance have been achieved. Due to the resistance of WO3 particles to corrosion in terms of electrochemical behavior, optimal composites have the lowest thermodynamic corrosion propensity and show higher pitting corrosion resistance. In addition, if the amount of TiO and WO3 is large, the formation of a continuous protective layer on the surface will be delayed and the corrosion resistance will decrease.
