Abstract
A rotor blade for a wind turbine having a first blade section and a second blade section coupled to the first blade section to form the rotor blade. Each of the first blade section and the second blade section has a leading edge and a trailing edge. A first sparcap including a carbon material is positioned on an inner surface of the first blade section. A second sparcap including a glass material is positioned on the first blade section. The second sparcap is positioned with respect to the first sparcap in a leading edge direction or a trailing edge direction.

A rotor blade for a wind turbine, said rotor blade comprising:
- a first blade section and a second blade section coupled to said first blade section to form said rotor blade, each of said first blade section and said second blade section having a leading edge and a trailing edge;
- a first sparcap comprising a carbon material and positioned on an inner surface of said first blade section;
- and
- a second sparcap comprising a glass material and positioned on said first blade section, said second sparcap positioned with respect to said first sparcap in one of a leading edge direction and a trailing edge direction.
A rotor blade for a wind turbine, said rotor blade comprising:
- a first blade section and a second blade section coupled to said first blade section to form said rotor blade, each of said first blade section and said second blade section having a leading edge and a trailing edge;
- a first sparcap comprising a glass material, said first sparcap positioned on an inner surface of said first blade section;
- a second sparcap coupled to said first sparcap, said second sparcap comprising a glass material and positioned on an inner surface of said second blade section;
- a third sparcap comprising a carbon material and positioned on the inner surface of said first blade section, said third sparcap positioned with respect to said first sparcap in one of a leading edge direction and a trailing edge direction;
- and
- a fourth sparcap coupled to said third sparcap, said fourth sparcap comprising a carbon material and positioned on the inner surface of said second blade section.
