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.

1. A method of assembling a modular rotor blade of a wind turbine, the method comprising: identifying a main blade structure comprising a blade root section, the blade root section comprising a body portion that extends from a blade root of the rotor blade up to a maximum chord of the rotor blade, the blade root section comprising one or more one or more continuous spar caps extending through the blade root section and past the maximum chord of the rotor blade such that portions of the one or more continuous spar caps are exposed, the main blade structure constructed, at least in part, from a thermoset material reinforced with at least one first fiber material;identifying at least one blade segment, constructed at least in part, of a thermoplastic material reinforced with at least one second fiber material;bonding one or more thermoplastic layers at an interface between the thermoset material and the thermoplastic material via one or more mechanical fasteners; and,welding the thermoplastic material of the at least one blade segment to the one or more thermoplastic layers at the interface between the thermoset material of the main blade structure and the thermoplastic material of the at least one blade segment. 2. The method of claim 1, wherein the first and second fiber materials comprise at least one of glass fibers, carbon fibers, polymer fibers, ceramic fibers, nanofibers, or metal fibers. 3. The method of claim 1, further comprising securing a plurality of blade segments to the main blade structure and joining adjacent blade segments together via welding. 4. The method of claim 1, further comprising pre-forming at least a portion of the main blade structure with the thermoset material. 5. The method of claim 4, wherein pre-forming at least a portion of the main blade structure with the one or more thermoplastic layers further comprises at least one of co-curing the one or more thermoplastic layers with the thermoset main blade structure, co-infusing the one or more thermoplastic layers with the thermoset main blade structure, mechanically fastening the one or more thermoplastic layers onto the thermoset main blade structure, or bonding the one or more thermoplastic layers onto the thermoset main blade structure via at least one of an adhesive or a resin. 6. The method of claim 1, wherein the main blade structure further comprises at least one of a blade root section, a blade tip section, or one or more shear webs. 7. The method of claim 6, further comprising pre-forming the blade root section by joining a plurality of root portions of the blade root section together via welding. 8. The method of claim 6, further comprising securing the one or more continuous spar caps to the blade root section, the one or more continuous spar caps extending in a generally span-wise direction and within the at least one blade segment. 9. The method of claim 8, wherein securing the at least one blade segment to the main blade structure further comprises securing the at least one blade segment to the one or more continuous spar caps. 10. The method of claim 9, further comprising securing the one or more continuous spar caps to the blade root section before securing the at least one blade segment to the one or more continuous spar caps. 11. The method of claim 8, further comprising securing the at least one blade segment to the one or more continuous spar caps before securing the one or more continuous spar caps to the blade root section. 12. A method of assembling a modular rotor blade of a wind turbine, the method comprising: identifying a main blade structure comprising one or more one or more continuous spar caps, the main blade structure, constructed, at least in part, of a thermoset material reinforced with at least one fiber material, the fiber material comprising at least one of glass fibers, carbon fibers, polymer fibers, ceramic fibers, nanofibers, or metal fibers; and,identifying at least one blade segment constructed, at least in part, from a thermoplastic material;providing one or more thermoset layers at an interface between the main blade structure and the at least one blade segment; and,bonding the at least one blade segment to the main blade structure at the interface. 13. The method of claim 12, further comprising providing at least one of an adhesive or a resin between the at least one blade segment and the main blade structure before welding the at least one blade segment to the main blade structure at the interface. 14. The method of claim 12, wherein joining the at least one blade segment to the main blade structure at the interface further comprises bonding the at least one blade segment to the main blade structure at the interface via at least one of an adhesive or one or more mechanical fasteners.
