Abstract: A spar assembly for a rotor blade including a beam structure extending between a closed first end and a second end configured for coupling within a shell of the rotor blade. The beam structure includes a contacting portion extending in a span-wise direction from the second end, a joint portion extending in the span-wise direction from the first end toward the contacting portion, and a transition region between the contacting portion and the joint portion. The contacting portion includes one or more contoured surfaces oriented toward at least one of an internal surface of a pressure or suction side of the rotor blade and configured to follow a contour of one of the pressure or suction side of the rotor blade. The joint portion includes one or more linear surfaces oriented in the same direction as the contoured surface(s). The transition region transitions the contoured surface(s) to the linear surface(s).

Abstract: A method for manufacturing a structural component of a blade segment for a segmented rotor blade of a wind turbine includes providing a mold of the structural component. The mold has an outer wall that defines an outer surface of the structural component. The method also includes securing at least one tooling pin to the outer wall for defining a pin joint slot in the structural component. Further, the method includes laying up one or more outer fiber layers in the mold so as to at least partially cover the outer wall. The outer fiber layer(s) has at least one hole that receives the tooling pin(s). As such, the outer fiber layer(s) form the outer surface of the structural component. Moreover, the method includes placing one or more structural features atop the outer fiber layer(s) in the mold. In addition, the method includes infusing the outer fiber layer(s) and the structural feature(s) together via a resin material so as to form the structural component.

Abstract: A wind turbine composite laminate component and method for producing it is disclosed as initially assembling a laminated structure having at least two reinforced layers and a plurality of interleaf layers positioned adjacent to one of the at least two reinforced layers. Then placing the laminated structure into a mold where resin is sequentially and independently transferred into each of the plurality of interleaf layers. Then curing the transferred resin in the laminated structure to form a composite laminate component having the at least two reinforced layers, the plurality of interleaf layers, and cured resin.

Abstract: A method for producing a hollow composite structure, such as a spar beam for a wind turbine blade, includes placing a membrane within a mold tool, the membrane being permeable to air and impermeable to resin. A mandrel is placed within the mold tool, the mandrel enclosed in an air tight layer that includes a vent. Fiber reinforcement material is placed around the mandrel within the mold tool and the membrane is sealed at least partly around the fiber reinforcement material and mandrel. The mold tool is closed with the vent line from the mandrel extending through the sealed membrane to outside of the mold tool. A vacuum is drawn in the mold tool while the mandrel is vented to outside of the mold tool, and while the vacuum is being drawn, resin is infused into the mold tool around the mandrel such that the resin is drawn towards the membrane.

Abstract: The present disclosure is directed to a rotor blade assembly for a wind turbine having a first rotor blade segment with a first spar cap segment and a second rotor blade segment with a second spar cap segment. The first and second spar cap segments are arranged together at an interface and are constructed of a composite material. Further, the rotor blade assembly includes a joint assembly at the interface of the first and second spar cap segments. The joint assembly is constructed of a first metal joint secured to the first spar cap segment and a second metal joint secured to second spar cap segment. Moreover, the first and second metal joints are welded together at a weld area.

Abstract: A method for producing a hollow composite structure, such as a spar beam for use in a wind turbine blade, includes placing fiber reinforcement material around a mandrel within a mold, and curing the fiber reinforcement material. The mandrel is formed from a compressible material having a rigid neutral state with a rigidity to maintain a defined shape of the mandrel during lay up and curing of the fiber reinforcement material. Subsequent to curing, a vacuum is drawn on the mandrel to compress the compressible material so that the compressed mandrel can be drawn out through an opening in the composite structure, the opening having a size such that the mandrel could not be withdrawn through the opening in the rigid neutral state of the mandrel.

Abstract: A method for manufacturing a structural component of a blade segment for a segmented rotor blade of a wind turbine includes forming first and second portions of the structural component. The first and second portions include respective holes that align in a chord-wise direction. The method also includes placing the first and second portions of the structural component into a mold such that their respective holes align in the chord-wise direction. Further, the method includes placing a tooling pin through the aligned holes. In addition, the method includes infusing the first and second sides together in the second mold via a resin material so as to form the structural component. Moreover, the method includes removing the tooling pin after the structural component has cured.
