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: Methods for joining a first blade component and a second blade component of a rotor blade together includes printing and depositing, via a computer numeric control (CNC) device, at least one three-dimensional (3-D) grid structure at a first joint area of the rotor blade. The first joint area contains the first blade component interfacing with the second blade component. The method also includes providing an adhesive at the first joint area to at least partially fill the grid structure. Further, the method includes securing the first blade component and the second blade component together at the first joint area via the adhesive.

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: 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: 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.
