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.
