Abstract: A method for assembling a shear web assembly of a wind turbine includes providing at least one spar cap. The method also includes forming a spar connecting member of a thermoplastic material via additive manufacturing. Further, the method includes securing the spar connecting member to the spar cap. Moreover, the method includes providing a shear web, forming a web connecting member of a thermoplastic material via additive manufacturing, and securing the web connecting member at a first end of the shear web. In addition, the method includes interconnecting the web connecting member and the spar connecting member at a joint. Thus, the method further includes heating the joint to secure the web connecting member and the spar connecting member together.

Abstract: Methods for manufacturing a wind turbine rotor blade having a flatback airfoil configuration along at least a portion of a span of the rotor blade include providing a shell mold of the rotor blade. The method also includes laying up an outer skin layer of the rotor blade into the shell mold. Further, the method includes placing at least one pre-fabricated corner of the flatback airfoil configuration into the shell mold. The pre-fabricated corner(s) has a pointed edge. The method also includes infusing the outer skin layer with the pre-fabricated corner(s) to form the flatback airfoil configuration.

Abstract: The present disclosure is directed to an apparatus and method for manufacturing a composite component. The apparatus includes a mold onto which the composite component is formed. The mold is disposed within a grid defined by a first axis and a second axis. The apparatus further includes a first frame assembly disposed above the mold and a plurality of machine heads coupled to the first frame assembly within the grid in an adjacent arrangement along the first axis. At least one of the mold or the plurality of machine heads is moveable along the first axis, the second axis, or both. At least one of the machine heads of the plurality of machine heads is moveable independently of one another along a third axis. A second frame assembly is moveable above the mold along the first axis, the second axis, or both. The second frame assembly includes a holding device. The holding device affixes to and releases from an outer skin to place and displace the outer skin at the mold.

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: The present disclosure is directed to a method of manufacturing a modular rotor blade for a wind turbine. The method includes providing a plurality of resin systems for manufacturing a plurality of blade components for the modular rotor blade. Each of the resin systems includes at least one of a thermoset material or a thermoplastic material, optionally a fiber reinforcement material, and at least one additive. Thus, the method includes determining a resin system for each of the blade components based on a location and/or function of each blade component in the rotor blade. In addition, the method includes forming each of the blade components of the rotor blade from one of the plurality of resin systems and securing each of the blade components together to form the modular rotor blade.

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: The present disclosure is directed to a shear web for a rotor blade of a wind turbine and a method of manufacturing and assembling same. The rotor blade generally includes an upper shell member having an upper spar cap configured on an internal surface thereof and a lower shell member having a lower spar cap configured on an internal surface thereof. Further, the shear web extends between the spar caps along a longitudinal length of the blade. In addition, the shear web includes first and second outer pultruded layers at least partially encompassing a core material, wherein end portions of the first and second outer pultruded layers form compressed flanges at opposing ends of the shear web.
