1. A rotor blade for a wind turbine, the rotor blade comprising:

  • a first blade component formed from a first fiber-reinforced composite including a first matrix material, the first matrix material primarily corresponding to a first thermoplastic resin material;

    a second blade component configured to be coupled to the first blade component at a joint interface, the second blade component formed from a second fiber-reinforced composite including a second matrix material, the second matrix material primarily corresponding to a second thermoplastic resin material, the second thermoplastic resin material differing from the first thermoplastic resin material; and

    at least one additional layer of thermoplastic resin material being positioned on the second fiber-reinforced composite or integrated into the second fiber-reinforced composite at the joint interface, the at least one additional layer of the thermoplastic resin material differing from the second thermoplastic resin material,wherein the first thermoplastic resin material of the first fiber-reinforced composite is welded to the at least one additional layer of the thermoplastic resin material to form a welded joint at the joint interface between the first blade component and the second blade component.
