A method for producing a reinforcement member of composite material. The method includes producing a planar preform by stacking sheets of pre-impregnated fibers, heating the preform, and deforming the preform on a mold surmounted by an upper die whose shape confirms to a central portion of the reinforcement member to be obtained. The reinforcement member wings are in contact with the mold at two opposite lateral sides of the upper die after deformation. The deformed preform is also baked. Prior to deformation of the preform, a coating is applied promoting a sliding between the preform and the mold during the deformation. The coating comprises two tear-off strips superimposed on each other. A first tear-off strip is in the form of a pre-impregnated material in contact with the preform and a second tear-off strip is in the form of a dry material superimposed on the first tear-off strip.

A shear web mould system for manufacturing a wind turbine component in form of an I-shaped shear web having a web body and a first web foot flange at a first end of the web body and a second web foot flange at a second end of the web body is described. The system comprises a central moulding portion for forming at least a part of the web body, a first moulding plate for forming at least a part of the first web foot flange, and a second moulding plate for forming at least a part of the second web foot flange. The angles of the first moulding plate and the second moulding plate relative to the central moulding portion are adjustable.

A method and mould system for manufacturing I-shaped shear webs for wind turbine blades are described. The mould system comprises a lower web mould part having a concave shape with diverging side parts for manufacturing first sides of I-web foot flanges, and an upper mould part having a concave shape with converging side parts for manufacturing other sides of the I-web foot flanges.

A manufacturing method of a honeycomb structure forming die includes a linear slit forming step of forming, in a kneaded material discharging surface of a die substrate, a plurality of linear slits which are straight from one end to the other end on the kneaded material discharging surface, a slit sealing material disposing step of disposing a slit sealing material in parts of the plurality of linear slits, and a back hole forming step of forming back holes to introduce a kneaded material, in a kneaded material introducing surface of the die substrate which is present on a side opposite to the kneaded material discharging surface.

A bladder mandrel package, used to manufacture a composite structure, includes a mandrel and a wrap ply, surrounding the mandrel to form a wrapped mandrel. The bladder mandrel package also includes a first radius filler, coupled to the wrap ply at a first radius of the wrapped mandrel, and a second radius filler coupled to the wrap ply at a second radius of the wrapped mandrel. The mandrel, the wrap ply, the first radius filler, and the second radius filler are consolidated to from the bladder mandrel package.

The invention relates to an elongate profiled object having a cross section, the object comprising a peripheral wall, forming a hollow profile extending in a longitudinal direction, wherein at least part of the peripheral wall is provided with a reinforcement layer extending in at least the longitudinal direction of the elongate profiled object, wherein the reinforcement layer comprises a tape or a laminate of tapes, wherein the reinforcement layer has a thickness of at least 0.6 mm and the tape is made of a first thermoplastic composition, which is a fiber reinforced thermoplastic composition comprising a flame retardant, wherein the elongate profiled object is made of a second thermoplastic composition.

A forming device, system, and method for continuous forming of a semi-finished fiber product. The semi-finished fiber product is supported flatly from a first side and is at least locally restricted in its freedom of movement, for example pressed on and/or guided, on another side opposite the first side. The further restriction occurs in relation to a guiding area at at least one constant location or region past which the semi-finished fiber product is guided. Shaping tools and guiding areas defined thereby are used for support, and hold-down devices and their contact surfaces are used for further restriction. The further restriction is carried out transversely to a feed motion direction of the semi-finished fiber product through the forming device. The further restriction and the flat guidance serve to reduce formation of undulations and folds.

A system for manufacturing a composite assembly includes a first mandrel, a second mandrel, a first wrap plate, and a second wrap plate. The first wrap plate and the second wrap plate are positionable in side-by-side relation for receiving a wrap material stack. The first wrap plate and/or the second wrap plate are translatable to a wrap plate open position defining a wrap plate gap between the first and second wrap plate surface edge for receiving a bladder. The second mandrel is translatable to a mandrel open position defining a mandrel gap between the first and second mandrel surface edge. The wrap plate gap and the mandrel gap are configured to receive the wrap material stack formed around a bladder. The first and second wrap plate are configured to fold a first and second material stack base portion into overlapping relation with each other on the bladder top.

Method and device for manufacturing a profile member of composite material, the cross-section of which has three branches, including the steps of: —moving together two opposite edges of a panel (2) of sheet material in such a manner that these two opposite edges are juxtapositioned in one juxtapositioning direction; translating a pair of jaws (20) in a direction perpendicular to the juxta-positioning direction in such a manner that the pair of jaws (20) is positioned on either side of the opposite juxtapositioned edges, this translational movement of the pair of jaws (20) being carried out in the direction of a base (25); —simultaneously pressing the sheet material between the two jaws (20), on the one hand, and between the jaws (20) and the base (25), on the other hand; —finishing the profile member of composite material by hardening with a matrix with which the sheet material is impregnated.

Various embodiments relate to a device for the production of preforms for aircraft structural components, having a supply unit for the continuous supply of a layer structure with at least one fiber layer, having a heating unit with at least one infrared heater which has an infrared radiation source, wherein the supplied layer structure is passed through the heating unit in a conveying direction and can be heated there over at least part of its width in cross section by the at least one infrared heater, a disk which is permeable to infrared radiation being arranged between the layer structure and the infrared heater.
