ABSTRACT:
A sparcap for a wind turbine rotor blade. The sparcap includes a first carbon material layer coupled to an inner surface of the wind turbine rotor blade. The first carbon material layer extends along at least a portion of a length of the wind turbine rotor blade. A core material is coupled to the first carbon material layer. The core material is positioned with respect to a buckling prone region of the wind turbine rotor blade. A second carbon material layer covers the core material and is coupled to the first carbon material layer and/or the core material. The second carbon material layer extends along at least a portion of the length of the wind turbine rotor blade.
