Abstract
Provided is a method of manufacturing an adaptable pre-cast resin-infused carbon-fiber beam, which method includes the steps of arranging a plurality of elongate carbon-fiber blocks side by side; arranging sheets to enclose the blocks and to extend over opposing faces of adjacent blocks; arranging the sheets to converge as an outwardly projecting elongate bead at a junction between adjacent blocks; and pulling on the elongate bead to inhibit resin flow between blocks during a resin infusion step. Also provided is a pre-cast adaptable carbon-fiber beam manufactured using that method; a method of manufacturing a wind turbine rotor blade; and a wind turbine rotor blade.
Claims6
A method of manufacturing an adaptable pre-cast resin-infused carbon-fiber beam, which method comprises:
- arranging a plurality of elongate carbon-fiber blocks side by side;
- arranging sheets to enclose the blocks and to extend over opposing faces of adjacent blocks;
- arranging the sheets to converge as an outwardly projecting elongate bead at a junction between adjacent blocks;
- pulling on the elongate bead;
- and
- performing a resin infusion step;
- wherein the pulling on the elongate bead inhibits resin flow between blocks during the resin infusion step.
A method of manufacturing a wind turbine rotor blade, which method comprises:
- providing a rotor blade mold to receive a composite layup;
- providing a pre-cast adaptable carbon-fiber beam having a plurality of resin-infused blocks, wherein at least one pair of adjacent blocks are joined by an elongate bead formed by sheets and are pivotable about the elongate bead;
- incorporating the pre-cast carbon-fiber beam in the composite layup;
- and
- adjusting the shape of the pre-cast carbon-fiber beam according to the shape of the rotor blade mold.
