Provided is a mold adapted for producing at least a part of a wind turbine blade, including a support and shell fixed to the support for accommodating blade building elements to be embedded in a resin matrix, wherein the shell includes at least one main body shell element and several diverse tip shell elements, which are exchangeably fixable to the support.

Methods are provided for joining a composite component, such as a rotor blade of a wind turbine. Accordingly, a first blade segment is provided and a bladder assembly is positioned thereon. Additionally, an adhesive element is positioned in a first position on the first blade segment. A second blade segment is positioned with the first blade segment so as to define an inner cavity therebetween. The inner cavity contains the adhesive element and the bladder assembly, but the adhesive element does not contact the second blade segment while in the first position. The bladder assembly is inflated to transition the adhesive element to a second position in contact with both the first blade segment and the second blade segment. With the adhesive element in contact with both blade segments, the adhesive element is allowed to cure in order to secure the blade segments to one another.

The present invention relates to a method of manufacturing a wind turbine blade, comprising arranging one or more layers of fibre material and a preform in a mould (66), injecting the one or more layers of fibre material and the preform (76) with a curable resin, and curing the resin. The preform (76) is impregnated with a curing promoter such that the concentration of curing promoter varies spatially within the preform.

The present invention relates to method of manufacturing a wind turbine blade, the method comprising the steps of providing a first shell half and a second shell half, providing a shear web having a first edge and an opposing second edge, and attaching the first edge of the shear web to an inner surface of the first shell half. One or more guide members are mounted onto an inner surface of the second shell half for guiding the shear web, each guide member comprising a hollow body and a guiding surface.

A method produces an injection molded part. A plastic material is injected into a cavity for forming the injection molded part. The plastic material in a flow line region of the cavity, where the plastic material from two directions coincides during an injection molding process, is at least partially removed from the cavity via at least two overflow points and, in so doing, is locally swirled or mixed between the overflow points.

A method for measuring bondline thickness of a wind turbine blade including scanning a first blade shell in a first mold half, the first mold half having a mold flange and a mold knob, forming a first scan; scanning a second blade shell in a second mold half, the second mold half having a mold flange and a mold knob, forming a second scan; scanning the at least one shear web exterior to the mold, forming a third scan; bonding the at least one shear web to the first blade shell; scanning the bonded at least one shear web and the first blade shell, forming a fourth scan; closing the first mold half onto the second mold half to form a closed mold; scanning the mold flanges and the mold knobs of the closed mold, forming a fifth scan; aligning the first, second, third, fourth and fifth scans; and measuring at least one bondline of the aligned scans.

Systems and method for producing a small-scale mixer are provided. In some implementations, a method for includes obtaining dimensions of an at-scale mixer. The method also includes determining first dimensions of the small-scale mixer based on respective dimensions of the at-scale mixer. The method further includes determining second dimensions of the small-scale mixer independent of the dimensions of the at-scale mixer. Additionally, the method includes generating the small-scale mixer using the first dimensions and the second dimensions using a three-dimensional printer.

A mold for manufacturing a turbomachine fan casing of composite material, includes a mandrel around which a fibrous preform of the fan casing is to be wound; counter-mold angular sectors assembled on the external contour of the mandrel which are intended to close the mold and to compact the fibrous preform wound on the mandrel; wherein each angular sector includes a first lateral flange positioned at the first end of the angular sectors and a second lateral flange positioned at a second end of the angular sectors, the first and second lateral flanges cooperating respectively with the second and first lateral flanges of the adjacent angular sectors. An angular sector includes a first groove formed in the first of second lateral flange, a first seal being positioned in the first groove, the first seal to be compressed between the first and second lateral flanges of two adjacent angular sectors.

A method for transferring an adhesive onto a part intended to be glued on a carrier, the adhesive being in the form of a double-sided film including a separator on each face, the part including an internal concave portion that does not enable uniform application of the adhesive film once the separators have been removed. The method includes attaching the adhesive film to a punch that matches the shape of the part within a range that approximately corresponds to the thickness of the adhesive film; removing the separator from the side of the adhesive film that is to be attached to the part; setting the part on the punch covered with the adhesive film that has had its separator removed; and transferring the adhesive film onto the part by creating a vacuum between the part and the punch by means of a vacuum device.

PMMA-based rigid foams can be used as the core material of sandwich components in rotor blades of wind power plants and in boatbuilding.
