Abstract: A joint assembly for a wind turbine rotor blade includes a male structural member extending longitudinally through female structural members configured with a plurality of rotor blade segments. The female structural member includes first bore holes on opposing sides thereof that are aligned in a chord-wise direction. The male structural member includes second bore holes on opposing sides thereof that are aligned with the first bore holes. At least one chord-wise extending gap is defined between an outer side surface of the male structural member and an inner side surface of the female structural member. A chord-wise extending pin extends through the first and second bore holes to join the male and female structural members. At least one flanged bushing is arranged in the first and second bore holes such that a flange of the bushing extends within the chord-wise extending gap.

Abstract: The present disclosure is directed to a method for bonding composite blade components of a rotor blade of a wind turbine. The method includes providing a first blade component being constructed of a first composite material. The method also includes providing a second blade component being constructed of a second composite material. Further, the method includes arranging the first and second blade components together at an interface. Another step includes placing one or more layers of a wetted composite material between the first and second blade components at the interface. The method also includes allowing the one or more layers of the wetted composite material at the interface to cure.

Abstract: The present disclosure is directed to a rotor blade component for a wind turbine. The rotor blade component includes a plurality of pre-cured members arranged in one or more layers. Each of the pre-cured members is constructed of a plurality of fiber materials cured together via a resin material having a first stiffness and at least additional material having a second stiffness. Further, the second stiffness is lower than the first stiffness. As such, the additional low-stiffness material is cured within the resin material so as to increase flexibility of the pre-cured members.

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.

Abstract: The present disclosure is directed to thermoplastic airflow modifying elements for a rotor blade for a wind turbine and methods of assembling same. 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.

Abstract: Rotor blades and methods for joining blade components of rotor blades are provided. A method includes positioning an insert between and in contact with a first blade component and a second blade component. At least one of the first blade component or the second blade component includes a thermoplastic resin. The insert includes a thermoplastic resin and an energy absorptive pigment. The method further includes heating the thermoplastic resin of the at least one of the first blade component or the second blade component and the thermoplastic resin of the insert. The method further includes cooling the thermoplastic resin of the at least one of the first blade component or the second blade component and the thermoplastic resin of the insert. The heating step and the cooling step join the first blade component, the second blade component and the insert together.

Abstract: The present disclosure is directed methods for modifying molds of rotor blades of a wind turbine. In certain embodiments, the blade mold is constructed, at least in part, of a thermoplastic material optionally reinforced with a fiber material. In one embodiment, the method includes identifying at least one blade mold addition for the mold of the rotor blade and positioning the blade mold addition at a predetermined location of the mold of the rotor blade. Further, the blade mold addition is constructed, at least in part, of a thermoplastic material. Thus, the method includes applying at least one of heat, pressure, or one or more chemicals at an interface of the blade mold addition and the mold so as to join the blade mold addition to the mold. In further embodiments, the methods described herein are also directed repairing thermoplastic blade molds.

Abstract: The present disclosure is directed to a method for forming a wind turbine rotor blade. The method includes placing first and second prefabricated skin panels defining a portion of a root section of the wind turbine rotor blade, a pressure side of the wind turbine rotor blade, or a suction side of the wind turbine rotor blade in a mold. The first and second prefabricated skin panels partially overlap to define a connection region. A vacuum bag is placed over the mold. The connection region is infused with a resin.
