Abstract: The present disclosure is directed to methods for manufacturing wind turbine rotor blades and components thereof, e.g. using 3D printing. In one embodiment, the method includes forming a rotor blade structure having a first surface and an opposing, second surface, the first and second surfaces being substantially flat. Another step includes printing a leading edge segment of the rotor blade onto the first surface, wherein heat from the printing bonds the leading edge segment to the first surface. The method also includes rotating the rotor blade structure having the leading edge segment attached thereto. A further step includes printing a trailing edge segment of the rotor blade onto the second surface, wherein heat from the printing bonds the trailing edge segment to the second surface. Another step includes securing one or more fiber-reinforced outer skins to the leading and trailing edge segments so as to complete the rotor blade.

Abstract: A method for manufacturing a rotor blade component of a rotor blade includes feeding a flat sheet of material into a thermoforming system, wherein the material comprises at least one of a thermoplastic or thermoset material. The method also includes heating the flat sheet of material via the thermoforming system. Further, the method includes shaping the heated flat sheet of material via at least one roller of the thermoforming system into a desired curved shape. Moreover, the method includes dispensing the shaped sheet of material from the thermoforming system. In addition, the method includes cooling the shaped sheet of material to form the rotor blade component.

Abstract: Wind turbine rotor blade components including pultruded rods and methods of manufacturing the same are disclosed. More specifically, the rotor blade component includes a plurality of pultruded rods housed within an enclosed primary outer casing. The enclosed primary outer casing includes a hollow interior, a root end, and an opposing tip. As such, each of the plurality of pultruded rods is received within the enclosed primary outer casing and secured therein via a first resin material. Further, an arrangement of the plurality of pultruded rods within the primary outer casing and a relationship of a maximum dimension of each of the plurality of pultruded rods and a maximum dimension of the enclosed primary outer casing are configured to maximize flexibility of the rotor blade component.

Abstract: A rotor blade of a wind turbine having a pultruded spar cap is disclosed. The rotor blade includes a blade root and a blade tip. The blade root includes at least one root insert. The rotor blade also includes at least one spar cap constructed of a plurality of pultruded members grouped together to form one or more layers from the blade tip towards the blade root. Further, the pultruded members separate into one or more pultruded member bundles as the spar cap approaches the blade root. The pultruded member bundles fit within the root insert, along with the blade bolts, such that compression and tension loads of the rotor blade are transferred through the pultruded members.

Abstract: A rotor blade segment of a wind turbine includes a seamless leading edge surface. A method of manufacturing a rotor blade segment of a wind turbine, the rotor blade segment having a seamless leading edge surface, includes forming an outer skin of the rotor blade segment. The outer skin defines a continuous outer surface. The continuous outer surface includes a pressure side surface extending between a pressure side aft edge and a pressure side forward edge, a suction side surface extending between a suction side forward edge and a suction side aft edge, and the seamless leading edge surface extends between the pressure side forward edge and the suction side forward edge. After folding the outer skin, the pressure side surface is positioned opposite the suction side surface and the pressure side aft edge is proximate the suction side aft edge.
