Abstract: A spar cap for a rotor blade of a wind turbine may generally include an assembly of pre-cured laminate plates stacked on one top of the other, with the assembly including an outermost pre-cured plate, an innermost pre-cured plate positioned opposite the outermost pre-cured plate and a plurality of intermediate pre-cured plates stacked directly between the outermost and innermost pre-cured plates. The outermost pre-cured plate may be configured to be positioned adjacent to an inner surface of a body shell of the rotor blade. In addition, the outermost pre-cured plate may define a plate thickness that differs from a plate thickness defined by the innermost pre-cured plate by at least 50%.

Abstract: The present disclosure is directed methods for manufacturing spar caps for wind turbine rotor blades. In certain embodiments, the method includes forming an outer frame or tray of the spar cap via at least one of three-dimensional (3D) pultrusion, thermoforming, or 3D printing. As such, the outer frame has a varying cross-section that corresponds to a varying cross-section of the rotor blade along a span thereof. The method also includes arranging a plurality of structural materials (e.g. layers of pultruded plates) within the pultruded outer frame of the spar cap and infusing the structural materials and the outer frame together via a resin material so as to form the spar cap. The resulting spar cap can then be easily incorporated into conventional rotor blade manufacturing processes and/or welded or bonded to an existing rotor blade.

Abstract: A rotor blade may generally include a shell forming an outer skin of the blade, with the shell defining a chordwise curvature. The rotor blade may also include a spar cap extending within the shell along a spanwise direction of the blade. The spar cap may be formed from an assembly of pre-cured laminate plates. In addition, the rotor blade may include an interior shelf positioned directly between the shell and the spar cap. The interior shelf may include an outer surface extending adjacent to the shell and an inner surface opposite the outer surface. The outer surface may define a curved profile generally corresponding to a portion of the chordwise curvature of the shell and the inner surface may define a planar surface along which the spar cap extends in a chordwise direction of the blade. The interior shelf may correspond to a pre-fabricated insert for the blade.
