Abstract: A wind turbine blade has an upper shell member and a lower shell member bonded at a leading and trailing edge of the blade with a bond paste applied between respective forward and rearward edges of the shell members. At least one of the shell members includes a first inspection window defined therein along one of the leading edge or trailing edge at a location corresponding at least to a design minimum bond width of the bond paste applied at the respective leading edge or trailing edge. The inspection window provides a visible access through the shell member such that a visible indication is generated through the inspection window when bond paste is injected and reaches the minimum bond width location in the chord-wise direction.

The body shell may include a pressure side and a suction side extending between a leading edge and a trailing edge and may define an outer shell surface. The rotor blade may also include a leading edge cap coupled to the body shell at the leading edge. The leading edge cap may be formed from a fiber-reinforced composite including an inner surface extending directly adjacent to the body shell along a portion of the outer shell surface and an outer surface opposite the inner surface. The fiber-reinforced composite may include a plurality of fibers surrounded by a thermoplastic resin material, with the thermoplastic resin material extending throughout the fiber reinforced composite from the inner surface to the outer surface.

Abstract: The present subject matter is directed to a rotor blade assembly for a wind turbine having a pultruded component at an interface of a shear web and a spar cap. More specifically, the rotor blade assembly includes an upper shell member having an upper spar cap configured on an internal surface thereof and a lower shell member having a lower spar cap configured on an internal surface thereof. A shear web extends between the spar caps along a longitudinal length of the blade. Further, the shear web includes a first end and a second end. The first end is secured to the upper spar cap at a first interface and the second end is secured to the lower spar cap at a second interface. In addition, the shear web includes at least one pultruded component configured at either or both of the first or second interfaces between the first and second ends and the upper and lower spar caps, respectively.

Abstract: The present disclosure is directed to a pre-formed, continuous structural component for use in assembling a modular rotor blade for a wind turbine. Further, the structural component provides support to the modular rotor blade during operation. The pre-formed structural component includes a root portion and a body portion. The root portion is configured for mounting the structural component to a blade root section of the rotor blade. The body portion is configured to extend in a generally span-wise direction. Further, the body portion defines a predetermined cross-section having a flatback portion with a first end and a second end. In addition, the first and second ends each have a flange extending perpendicularly therefrom. Thus, each flange defines a mounting surface for one or more blade segments.

Abstract: The present disclosure is directed to a method for manufacturing a thermoset component having a weldable thermoplastic interface. The method includes forming a polymerized thermoplastic component having a removable protective layer on a portion thereof. Another step includes placing a plurality of dry plies and the thermoplastic component into a mold of the thermoset component with the removable protective layer facing an outer surface of the thermoset component mold. Thus, the method further includes co-infusing the dry plies and thermoplastic component with a resin material so as to form the thermoset component having a weldable thermoplastic interface.

Abstract: In one aspect, a method for manufacturing a spar cap for a wind turbine rotor blade may generally include stacking a plurality of plates together to form a plate assembly, wherein each of the plates is formed from a fiber-reinforced composite including a plurality of fibers surrounded by a thermoplastic resin material. The method may also include positioning the plate assembly relative to a mold defining a mold surface, wherein the mold surface is shaped so as to correspond to at least one blade parameter of the wind turbine rotor blade. In addition, the method may include applying pressure to the plate assembly via the mold such that at least a portion of the plate assembly conforms to the shape of the mold surface.

Abstract: The present disclosure is directed a method for repairing a rotor blade of a wind turbine. More specifically, in certain embodiments, the rotor blade may be constructed, at least in part, of a thermoplastic material reinforced with at least one fiber material. Thus, the method includes identifying at least one defect on the rotor blade. For example, in certain embodiments, the defect(s) as described herein may include a crack, creep, void, hole, distortion, deformation, scratch, or any other blade defect. The method also includes applying at least one of heat, pressure, and/or one or more chemicals to the defect(s) for a predetermined time period until the defect is repaired.
