Abstract: The present disclosure is directed to spar caps for wind turbine rotor blades and methods of manufacturing same. The spar cap includes a plurality of plies having varying lengths that are arranged in a tapered configuration. Further, the tapered configuration includes at least an upper portion and a lower portion. The upper portion is configured for attachment to at least one of a pressure side or a suction side of the rotor blade. Further, one or more plies of the upper and lower portions tapers towards an intermediate ply configured between the upper and lower portions of the spar cap. In addition, the intermediate ply has a length that is shorter than the plies in the upper and lower portions.

Abstract: A spar cap for a rotor blade of a wind turbine is disclosed. The rotor blade includes a blade root and a blade tip, leading and trailing edges, pressure and suction sides, and at least one spar cap configured on an internal surface of either or both the pressure or suction sides. The spar cap includes one or more layers of a first material and a second conductive material contacting at least one of the layers of the first material. Further, the conductive material is different than the first material. Thus, the conductive material is configured with the first material so as to create an equipotential spar cap.

Abstract: A wind turbine blade has an upper shell member and a lower shell member bonded at a leading and trailing edge of the blade with a bond paste applied between respective forward and rearward edges of the shell members. At least one of the shell members includes a first inspection window defined therein along one of the leading edge or trailing edge at a location corresponding at least to a design minimum bond width of the bond paste applied at the respective leading edge or trailing edge. The inspection window provides a visible access through the shell member such that a visible indication is generated through the inspection window when bond paste is injected and reaches the minimum bond width location in the chord-wise direction.
