Systems and methods for filament fastener that cures with composite part. One embodiment is a method of fabricating a composite part. The method includes placing layers of reinforcement fibers over a tool to form a laminate of composite material to be cured with a first resin, forming a filament fastener comprising bundled fibers with one or more texture elements around the bundled fibers, and coating the filament fastener with a second resin that is chemically compatible with the first resin. The method also includes inserting the filament fastener into the laminate through a plurality of the layers, and curing the filament fastener within the laminate to bind the plurality of the layers of the laminate with the one or more texture elements of the filament fastener via bonding of the first resin and the second resin to form the composite part with delamination resistance.

A method of making a wind turbine blade having at least one pultruded strip of fibrous reinforcing material integrated with a shell of the blade is described. The method comprises the steps of: providing at a first location a feed apparatus for dispensing a pultruded strip of fibrous reinforcing material; supporting a coiled pultruded strip of fibrous reinforcing material for rotation in the feed apparatus; causing the coiled strip to rotate in the feed apparatus at the first location; and feeding a free end of the strip from the feed apparatus in a feed direction towards a second location remote from the first location. An associated feed apparatus for use in the method is also described.

A method, apparatus, and system for managing nonconformances in laminates. A nonconformance management system comprises a sensor system and an analyzer in a computer system. The sensor that records layup information about the layup of layers on a workpiece platform and records inspection information about the laminate located on an inspection platform, wherein the laminate is formed from curing the workpiece. The analyzer in the computer system identifies a laminate nonconformance in the laminate using the inspection information, generates nonconformance information about the laminate nonconformance, and displays the nonconformance information about the laminate nonconformance on the laminate using a display system for an augmented reality display.

There is disclosed a method of manufacturing a fan blade for a gas turbine engine, the method comprising: providing a root insert comprising quasi-isotropic short fibre reinforced resin, providing a first sub-laminate of a fibre-reinforcement pre-form for the fan blade on a first mould surface, placing the root insert on the first sub-laminate at a position corresponding to a root of the fan blade, providing a second sub-laminate of the pre-form over the root insert and the first-sub-laminate, so that the root insert is at an intermediate position between the first and second sub-laminates; and applying heat and pressure to form the pre-form.

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

A 3D printer successively fuses sheet material in a stack to form a three-dimensional object. The sheet material may provide a mesh separating islands of material that will be fused to produce the desired three-dimensional object. The mesh provides support for the island material during the fusing process and may be removed afterwards.

A method for manufacturing a composite includes providing a first template including a cutout for a first layer of the composite, disposing the first layer in the cutout, and disposing a tablet, provided with an adhesive, on the first layer such that the first layer adheres to the tablet. Next, the tablet is removed, together with the first layer adhered thereto, from the cutout, and an adhesive is applied to a side of the first layer facing away from the tablet. A second template is provided that includes a cutout for a second layer of the composite, and then the second layer is disposed in the cutout. The tablet, together with the first layer adhered thereto, is disposed on the second layer disposed in the cutout of the second template, and the tablet is removed, together with the composite produced from the first and second layers, from the second template.

A patch lamination device includes a laminate feed roller, a laminating roller, and a laminate spreader. The laminate feed roller is configured to feed a patch laminate ribbon along a laminate path. The laminating roller is configured to laminate individual patch laminates of the ribbon to a surface of a card substrate. The laminate spreader is positioned between the laminate feed roller and the laminating roller. The laminate spreader is configured to reduce the formation of trough wrinkles in a patch laminate that is tensioned between the laminate feed roller and the laminating roller during lamination of the patch laminate to a card substrate using the laminating roller.

A laminating machine comprises at least one material source, configured as a sheet feeder, for sheets of a material to be laminated. The laminating machine further comprises at least one laminating unit. The laminating machine also comprises at least two lamination sources, each for at least one web-type laminating material. The laminating machine additionally comprises at least one laminating unit for producing a material web, which is laminated on both sides, from the sheets and the respective at least one laminating material. At least one lamination control device is disposed downstream of a laminating region of the laminating unit, along a transportation path provided for the transporting of the laminated material web. The control device monitors a control region, lying outside a transport region that is occupied by the transportation path provided for the laminated material web.

A method for manufacturing an acoustic absorption structure including an acoustically resistive layer, a cellular structure, a reflective layer and a plurality of acoustic elements positioned in cavities produced in the cellular structure. This method comprises steps of depositing fiber plies on a contact surface of the cellular structure, fitting a flexible jacket which covers a stack composed of the acoustically resistive layer, the cellular structure and the fiber plies, which is tightly linked with the deposition surface all around the stack, consolidating the fiber plies to form the reflective layer and the fixing thereof on the cellular structure, with a caul plate being inserted between the fiber plies and the flexible jacket during the consolidation step.
