Abstract: The present disclosure is directed to a method for manufacturing a blade component for a rotor blade of a wind turbine. The method includes arranging a fiber material in a mold of the blade component. The method also includes placing at least one pre-cured laminate material atop the fiber material. Another step includes infusing the fiber material and the pre-cured laminate material together via a resin material so as to form the blade component. The method also includes allowing the blade component to cure, the pre-cured laminate material forming at least a portion of an outer surface of the blade component.

Abstract: A rotor blade for a wind turbine may generally include a first blade component formed from a first fiber-reinforced composite including a first thermoplastic resin material and a second blade component configured to be coupled to the first blade component at a joint interface. The second blade component may be formed from a second fiber-reinforced composite including a second thermoplastic resin material. The second fiber-reinforced composite may include a low fiber region and a high fiber region, with the low fiber region having a fiber-weight fraction that is less than a fiber-weight fraction of the high fiber region. In addition, the first thermoplastic resin material of the first fiber-reinforced composite may be welded to the second thermoplastic resin material contained within the low fiber region of the second thermoplastic composite to form a welded joint at the joint interface between the first blade component and the second blade component.

The rotor blade may be constructed from at least one of a thermoset material or a thermoplastic material. Further, the rotor blade includes a blade shell defining an outer surface. Moreover, the rotor blade includes one or more layers of thermoplastic material infused to the outer surface of the blade shell so as to define one or more attachment locations. In addition, the rotor blade includes at least one airflow modifying element constructed, at least in part, from a thermoplastic material. Thus, the airflow modifying element(s) is welded to one of the attachment locations on the outer surface of the blade shell.
