Methods and devices for supporting of variety of different pre-cured composite stringers

Provided are methods and devices for supporting of variety of different pre-cured composite stringers after forming and prior to curing. A post-forming processing device comprises a base with a channel for receiving hat portions of different stringers. The device also comprises a support structure, at least partially extending within the channel. The support structure is configured to conform to different hat portions and to retain the shape of these hat portions. For example, the support structure is made from a flexible material, which conforms to any shape variations. In some examples, the support structure is made from a jamming material that is reshaped together with each of the pre-cured composite stringers. A post-forming processing device is used for supporting different pre-cured composite stringers while various operations are performed on these stringers, such as stringer trimming, inspection, installation of bladders and noodles, and the like.

METHOD OF ASSEMBLING A STRUCTURE IN AIRCRAFT OR SPACECRAFT PRODUCTION
20230226654 · 2023-07-20 ·

A method of assembling a structure in aircraft or spacecraft production wherein two components to be joined together at a joint are provided, each component comprising a joining region. Sealant is applied to one of the component joining regions. An arrangement is formed by positioning the components relative to each other, whereby an uncured layer of the sealant is formed between associated joining regions. The associated joining regions are clamped against each other using a clamping device, and a clamped state is maintained until the layer of sealant has cured to a pre-defined degree, the clamping device being installable on and transportable along with the arrangement. After the layer of sealant has cured to the pre-defined degree, drilling at a plurality of fastening positions is performed to obtain a hole of final dimension at each fastening position, and installation of a final fastener at each fastening position is performed.

Multifunctional surfacing films

The present invention is directed to multifunctional surfacing films each comprising: (a) a single layer of curable polymer composition having opposing first and second surfaces: (b) a peelable porous sheet disposed at or beneath the second surface; and (d) at least one porous sheet of functional material disposed within the single layer of curable polymer composition and positioned between the first surface and the peelable porous sheet, and methods of making and using such multifunctional surfacing films.

Fuselage component for an aircraft, method for producing a fuselage component, and aircraft
11560211 · 2023-01-24 · ·

A fuselage component for an aircraft, including a shell part composed of a fiber composite material and a stiffening structure which is connected to an inner surface of the shell part and has shaped parts composed of a fiber composite material, wherein the shaped parts each have a flat base section which extends along the inner surface of the shell part, and a step-shaped profile edge which extends in an encircling manner around the base section. The shaped parts are arranged in the form of parquetry with overlapping profile edges. As a result, the overlapping profile edges form stiffening profiles intersecting at an intersection. Furthermore, an aircraft which has at least one such fuselage component and a method for producing a fuselage component are described.
