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drawn out through an opening in the composite structure, the opening having a size such that the mandrel could not be withdrawn through the opening in the rigid neutral state of the mandrel.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 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 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: 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.
