Abstract
The use of premium material in the construction of wind turbine blades may provide increases in blade efficiency and enable the use of thinner blades. By providing a spar cap having a section of premium material having a constant thickness, the use of the premium material may be optimized to provide a more effective use of premium material. Additional material, which may be less expensive as well as heavier, may be added near the blade root to provide additional strength and stiffness to the blade.
