Patent number: 11780120Abstract: A device for manufacturing a composite component including a tool with a first and second sections forming first and second confinement surfaces, the sections movable relative to each other into and out of a fastening configuration. The device includes a closing mechanism with a closing section. In the fastening configuration, the first confinement surface and the second confinement surface face one another, and the sections and the closing mechanism are arranged such that a cavity is formed between the sections and the closing mechanism. The closing section is transferable from an open configuration into a closed configuration. In the closed configuration, the third confinement surface extends along a plane perpendicular to the first and second confinement surfaces, wherein, when the closing mechanism is heated from a first temperature to a second temperature, the closing section transfers from the open configuration into the closed configuration at a predefined temperature.Type: GrantFiled: November 24, 2021Date of Patent: October 10, 2023Assignee: Airbus Operations GmbHInventors: Hauke Seegel, Anja Häberle

Patent number: 11766839Abstract: A device and method for producing a component. The device is composed of two mold elements, wherein one of the mold elements has a cavity which communicates with the position of one side of a component to be produced. An inflatable tube which is fluidically linked to the surrounding atmosphere is provided in the cavity. A cover covers the first and the second mold element and seals the first and said second mold element in relation to the surrounding atmosphere. The tube is expanded by applying a vacuum within the sealed regions and the tube can shape or facilitate shaping the side of the component to be produced.Type: GrantFiled: August 13, 2019Date of Patent: September 26, 2023Assignee: Airbus Operations GmbHInventor: Hauke Seegel

Publication number: 20220194029Abstract: A method and apparatus for cutting a Non-Crimp Fabric for improving edge stability and reducing stitch retraction is disclosed. The part of the NCF to be cut is treated with a binder and heated to activate the binder and therefore bind the tows and stitches together. By treating only the cutting path the drapability of the wider fabric is maintained. This may be achieved by heating only the part of the NCF to be cut, or applying binder to only the part of the NCF to be cut. The NCF may be compressed and cooled before cutting to improve binding action. A ply cutter may be adapted to carry out the invention by including a heat source and optionally a binder dispenser, compressor and cooler.Type: ApplicationFiled: December 21, 2021Publication date: June 23, 2022Inventors: Hauke SEEGEL, Dominic BLOOM

Publication number: 20220152952Abstract: A method for producing a component from a fiber-reinforced plastic, wherein at least one ply of a semifinished fiber product having a peripheral contour is applied to the molding tool at a first temperature, wherein the contour lies within the peripheral edge. A compensating body, having a coefficient of thermal expansion which is greater than a coefficient of thermal expansion of the molding tool, is arranged along the peripheral edge, such that the compensating body extends from the edge in the direction of the peripheral contour. After sealing the arrangement, resin is introduced, and the arrangement is heated. As a result, the compensating body expands to a greater extent than the molding tool and encloses the semifinished fiber product in a flush manner, with the result that a shape of the component can correspond to an intended final shape and no longer has to be finish-machined.Type: ApplicationFiled: November 28, 2021Publication date: May 19, 2022Inventor: Hauke Seegel
