Abstract: A method for manufacturing a rotor blade panel of a wind turbine includes placing one or more fiber-reinforced outer skins into a mold of the rotor blade panel. The method also includes printing and depositing, via a computer numeric control (CNC) device, a plurality of rib members that form at least one three-dimensional (3-D) reinforcement grid structure onto an inner surface of the one or more fiber-reinforced outer skins. Further, the grid structure bonds to the one or more fiber-reinforced outer skins as the grid structure is deposited. Moreover, the method includes printing at least one additional feature into the grid structure.

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: In one aspect, a method for manufacturing a spar cap for a wind turbine rotor blade may generally include stacking a plurality of plates together to form a plate assembly, wherein each of the plates is formed from a fiber-reinforced composite including a plurality of fibers surrounded by a thermoplastic resin material. The method may also include positioning the plate assembly relative to a mold defining a mold surface, wherein the mold surface is shaped so as to correspond to at least one blade parameter of the wind turbine rotor blade. In addition, the method may include applying pressure to the plate assembly via the mold such that at least a portion of the plate assembly conforms to the shape of the mold surface.

Abstract: The present disclosure is directed a method for repairing a rotor blade of a wind turbine. More specifically, in certain embodiments, the rotor blade may be constructed, at least in part, of a thermoplastic material reinforced with at least one fiber material. Thus, the method includes identifying at least one defect on the rotor blade. For example, in certain embodiments, the defect(s) as described herein may include a crack, creep, void, hole, distortion, deformation, scratch, or any other blade defect. The method also includes applying at least one of heat, pressure, and/or one or more chemicals to the defect(s) for a predetermined time period until the defect is repaired.

Abstract: The present disclosure is directed to a method of assembling a modular rotor blade of a wind turbine. The method includes identifying a main blade structure, constructed at least in part, from at least one of a thermoset or a thermoplastic material. The method also includes identifying at least one blade segment, constructed at least in part, of a thermoplastic material reinforced with at least one of glass fibers or carbon fibers. Thus, the method also includes securing the at least one blade segment to the main blade structure, e.g. via welding.

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.
