    Abstract: A jointed rotor blade assembly may include a first blade segment having a first outer shell terminating at a first joint end and a second blade segment coupled to the first blade segment at a blade joint. The second blade segment may include a second outer shell terminating at a second joint end. The outer shells may overlap one another at the blade joint such that an overlapping region is defined between the first and second joint ends. In addition, the first outer shell may be spaced apart from the second outer shell along at least a portion of the overlapping region such that a gap is defined between the outer shells within the overlapping region. Moreover, the rotor blade assembly may include a sealing member positioned between the outer shells within the overlapping region that is configured to allow relative movement between the outer shells at the blade joint.

    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, wherein the second thermoplastic resin material differs from the first thermoplastic resin material. The rotor blade may also include an additional layer(s) of thermoplastic resin material positioned on or integrated into the second fiber-reinforced composite at the joint interface that differs from the second thermoplastic resin material. Moreover, the first thermoplastic resin material of the first fiber-reinforced composite may be welded to the additional layer(s) of the thermoplastic resin material to form a welded joint at the joint interface between the first and second blade components.

    Abstract: A joint assembly for joining rotor blade segments of a wind turbine rotor blade includes a female structural member secured within a first rotor blade segment. The female structural member includes first bore holes on opposing sides thereof that are aligned in a chord-wise direction. Further, the joint assembly includes a male structural member extending longitudinally from an end face of a second rotor blade segment. As such, the male structural member is received within the female structural member of the first rotor blade segment such that the first and second rotor blade segments are aligned and connected. The male structural member includes second bore holes on opposing sides thereof. Further, the second bore holes are aligned with the first bore holes. Moreover, the joint assembly includes at least one chord-wise extending pin extending through the first and second bore holes so as to join the first and second rotor blade segments. In addition, the male structural member has a height that increases from a blade root of the rotor blade towards the at least one chord-wise extending pin.

    Abstract: A pre-cured laminate plate for use within a component of a wind turbine rotor blade may generally include a plate body extending in a thickness direction between a first side and a second side and in a widthwise direction between a first end and a second end. The plate body may define a plate thickness between the first and second sides. The pre-cured laminate plate may also include a plurality of channels formed in the plate body between the first and second ends. Each channel may extend in the thickness direction between a top end that is open along the first side of the plate body and a bottom end that terminates at a location between the first and second sides of the plate body such that the plate body defines a reduced thickness between the bottom end of each channel and the second side of the plate body.
