Abstract: The present disclosure is directed to a method for manufacturing a thermoset component having a weldable thermoplastic interface. The method includes forming a polymerized thermoplastic component having a removable protective layer on a portion thereof. Another step includes placing a plurality of dry plies and the thermoplastic component into a mold of the thermoset component with the removable protective layer facing an outer surface of the thermoset component mold. Thus, the method further includes co-infusing the dry plies and thermoplastic component with a resin material so as to form the thermoset component having a weldable thermoplastic interface.

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 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.
