    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.

    Abstract: A robotic maintenance device (40) and method for repairing damage (26) around the leading edge (22) of a wind turbine blade (20) are provided. The maintenance device (40) includes a main chassis (42) that is configured to be mounted on the wind turbine blade (20), an applicator head (46) for applying a coating material (32) onto an exterior surface (30) of the blade (20) to cover and fill in damaged areas (26), and an environmental control module (60). The environmental control module (60) is located proximate the applicator head (46) and includes a tent (62) that selectively deploys over a portion of the leading edge (22) of the blade (20) behind operations of the applicator head (46) to define a curing zone. The coating material (32) within the curing zone can cure on the wind turbine blade (20) to complete the repair while remaining shielded from local environmental conditions such as wind and rain around the wind turbine blade (20). For example, the tent (62) can be configured to extend over a fixed length and move over that length behind the moving robotic maintenance device (40), or the tent (62) can be configured to secure on the blade (20) and be extended as the maintenance device (40) moves and conducts repair operations, with the tent (62) being retractable at the end of the maintenance process.

    Abstract: The present invention relates to a method of manufacturing a wind turbine rotor blade part comprising stacking a plurality of plies (70, 71, 72) to form a stack of plies (80) such that the stack of plies has at least one stepwise tapering edge (84, 85). A plurality of plastic fasteners (90) is used to interconnect the plies (70, 71, 72) by passing the plurality of plastic fasteners (90) through the stack of plies to form a stack of interconnected plies (82). The stacks of interconnected plies (82a, 82b, 82c, 82d) are arranged within the blade mold, followed by resin infusion into the one or more stacks of interconnected plies within the blade mold, and curing and/or hardening the resin in order to form the blade part.

    Abstract: A block for geotechnical applications is disclosed, the block having a composite body which is a section of a used wind turbine blade including a part of its leading edge, trailing edge and the windward surface and leeward surface of the used blade. The body is open from above and below. Fragments of the windward surface, leeward surface, leading edge and trailing edge of the used blade are the block's side walls. The inside of the body is filled with a filling material. A method of making a block for geotechnical applications is also disclosed. Under the method, a section is marked on a used wind turbine blade between its tip and root for mounting in a hub. Then, within this section, the block body is cut out, in two cutting planes parallel to each other, in the form of a fragment with a closed cross section, including a part of a leading edge, trailing edge, windward shell and leeward shell of this blade, then this body is filled with a filling material, making its filling.

    Abstract: A method of masking a mould for moulding a wind turbine blade shell part, the method comprising the steps of: arranging a masking device in a mould so that the masking device covers the non-coating zone of the mould surface, spraying a coating onto a mould surface of the mould so that the coating is applied to a coating zone of the mould surface and prevented from being applied to a non-coating zone of the mould surface by the arrangement of the masking device, and removing the masking device from the mould so that the non-coating zone is exposed. The masking device is configured so that, upon terminating spraying of the coating at the first longitudinal boundary of the coating zone, a lip portion of the masking device is separated from the coating applied on the coating zone by a gap.

    Abstract: A method for manufacturing a wind turbine blade, comprising the steps of: arranging (S2, S3) a joining portion (8) comprising a fibre lay-up inside adjacent blade sections, covering (S4) the joining portion (8) and the adjacent blade sections at least partially with a vacuum bag, and applying vacuum to a space (54) covered by the vacuum bag (19, 38), infusing at least the fibre lay-up (12, 13, 14, 15, 16, 17) with a resin (43) and curing (S5) the resin (43) to obtain a cured joining portion (44) joining the blade sections (20, 24) inside. A light-weight and at the same time strong blade section joint is provided. In particular, the strength of this laminate joint formed by vacuum infusion is comparable to the strength of the pristine laminate. Compared to a connection using an adhesive, the laminate joint formed by vacuum infusion provides a lighter and stronger blade section joint, in particular, a better weight-to-strength performance.
