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 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 method for manufacturing a root section of a wind turbine blade includes assembling a mold having an inner cylinder segment, an outer cylinder segment, and a bottom flange, wherein a radial space is defined between the inner and outer cylinders. Root hub connectors are attached circumferentially around the bottom flange so that the root hub connectors extend axially into the radial space. A first cartridge of pultruded rods is loaded into the space, wherein the first cartridge includes a plurality of first pultruded rods arranged adjacent to the inner cylinder segment. The space is sealed, for example with a lid or top flange, and the space is evacuated. A resin is infused into the space so that the resin migrates through the radial space between the pultruded rods, and is then cured. The root section is then removed from the mold. A wind turbine blade root section formed by the method is encompassed by the invention.
