20230135895 · 2023-05-04 ·

An insert device for sealing a conduit, wherein at least one component of the insert device is configured to separate and position at least one wire in the conduit in order to create a space or inner volume for a sealant to be introduced thereinto. The insert device can have a nozzle configured to allow precise injection of the sealant into the inner volume. The insert device can be operated for quick and reliably repeatable sealing of conduits.

MANUFACTURING METHODS AND RELATED STRUCTURES, FOR EXAMPLE USEFUL IN AIRFRAMES AND OTHER STRUCTURES
20230135989 · 2023-05-04 ·

A method of manufacturing includes assembling two or more parts (e.g., non-extrusions) or extrusions (e.g., metal extrusions or plastic extrusions) into an assembly; placing the assembly into a mold; injecting a core material (e.g., expandable foam) into an interior or cavity of the assembly while the assembly is retained in the mold; and removing a resulting structure from the mold. The parts or extrusions may be treated before injecting the core material. The core material may be hardened or cured. The parts or extrusions may include a skin portion and integral reinforcement structures or stiffeners, integral complementary joint portions or features to fasten one another together, and/or retainers or structural features shaped and positioned to capture and/or hold onto core.

11413797 · 2022-08-16 · ·

The invention relates to a connection element, in particular a thermal adhesive bonding boss, to be introduced into at least one component, in particular a hollow chamber component, in particular a plate-shaped hollow chamber component which has hollow chambers, under the effect of pressure and rotation, comprising a main part which comprises a thermoplastic synthetic material. The connection element has a longitudinal axis and is designed to rotate about the longitudinal axis, and the connection element has an upper face with a tool placement point and a lower face which faces away from the upper face, wherein the connection element has an expanding portion made of a thermally activatable expandable material on the main part on a circumferential surface extending between the upper face and the lower face.

Vehicle interior board and method for manufacturing same

A vehicle interior board which is thin, lightweight, has high strength, has less degradation, peeling and the like near an end portion of a metal plate, and has high quality and excellent productivity; and a method for manufacturing the same. The vehicle interior board includes a pair of metal plates and a foamed polyurethane layer formed between the pair of metal plates. A projecting ridge projecting outwardly and extending in a predetermined direction along the outer surface is formed on an outer surface of the metal plate. Thus, it is possible to obtain desired strength and rigidity even when the metal plates or the foamed polyurethane layer are thinned or when a lightweight aluminum plate or the like is adopted as the metal plates. Therefore, it is possible to reduce weight of a vehicle interior board.

DIELECTRIC HEATING OF FOAMABLE COMPOSITIONS

A method for dielectrically heating foamable composition to foam and set the composition is described. In particular, radio frequency (RF) heating is used to heat the foamable composition to provide insulation in the manufacture of an article.

Method of manufacturing a lightweight laminate

A method of producing a laminated article comprising placing a first metal skin, a core, and a second metal skin freely onto each other as discreet layers to provide a layered component; and forming the layered component into a shaped article via a die prior to producing a laminated article by applying pressure and heat to the shaped article, wherein at least the first skin moves relative to the core and/or second skin during the forming.

COMPOSITE MATERIALS
20210283880 · 2021-09-16 ·

Light weight composites with high flexural strength comprise epoxy foam sandwiched between two layers of facing material have high strength and low weight and can be used to replace steel structures. The facing layer may be fibrous material especially glass or carbon fibres, the facing material is preferably embedded into the epoxy matrix. Alternatively they may be matching box structures or concentric metal tubes. The sandwich structures may be prepared by laying up the fibre; coating and/or impregnating the layer with epoxy resin, laying a layer of heat activatable foamable epoxy material, providing a further layer of the fibrous material optionally coated and/or impregnated with epoxy resin on the foamable material and healing to foam and cure the epoxy materials. Alternatively they may be formed by extrusion of the foamable material between the surface layers.
