This invention relates to a fireproofing article and the method of manufacturing the same. The fireproofing article comprises an external portion and an inner portion. The external portion defines external surfaces of the fireproofing article that are exposed to the environment. The inner portion is formed inside of the external portion. The external portion and the inner portion are both porous and made of a fireproofing material. The external portion has a first material density and the inner portion has a second material density. The first material density is less than the second material density. The method of manufacturing a fireproofing article comprises forming the fireproofing article with a fireproofing material through 3D printing; wherein the fireproofing article formed is porous.

The present invention relates to a hybrid panel, comprising a panel comprising: a core, a first protecting layer on a first side of said core and a second protecting layer on a second side of said core; said panel defining an outside geometry thereof; and an overmolded portion which overlays at least a part of said panel, thereby changing said geometry of said panel at said part of said panel.

A tool for curing and bonding a honeycomb stack with void filler. The tool has a first tool piece with a cavity for receiving layers of unfilled honeycomb material and a second tool piece with a cavity for receiving at least one layer of void-filled honeycomb. The tool also has a compression seal arrangement that creates gas-tight seals between the first tool piece, second tool piece, and a barrier layer positioned between them, with a further seal covering the cavity of the first tool piece to form a gas-tight sealed volume including the first cavity, a pressure plate to cover the cavity of the second tool piece to apply pressure to the void-filled honeycomb, with a further seal to cover the pressure plate to form a gas-tight sealed volume including the second cavity.

Items may be packaged for shipping or storage using additive manufacturing techniques, also known as three dimensional (3-D) printing. Packages made by such processes may be referred to as 3-D printed packages and may include packing material printed at least partially around the item(s) and/or an outer cover printed about at least a portion of an exterior of the packing material and/or the item(s). A packaging system may include a 3-D printer and a computing device communicatively coupled to the 3-D printer. The computing device may obtain a packaging model describing a package for one or more items. A print module of the computing device may include instructions to print the package at least partially about the item(s) according to the packaging model.

A method for making a support element for the human body equipped with a first component or support component, a second component or padding component, wherein at least the second component or padding component is obtained by means of a three-dimensional printing technique; and an apparatus for implementing the method for obtaining the support element and support element thus obtained.

A component, including a part, comprising a honeycomb-like structure formed from at least a seamless resin-infused fiber composite material. The honeycomb-like structure includes a first plurality of cells, and a second plurality of cells, different than the first plurality of cells.

A cellular confinement system includes PET sheets and honeycomb-shaped cells formed by intercrossing the PET sheets. A connecting hole is provided at a joint where the PET sheets are intercrossed. An injection molded fixing component for connecting the PET sheets is provided at the connecting hole. The injection molded fixing component includes an injection molded rod arranged in the connecting hole and fixing plates each arranged to be fixedly connected to a corresponding end of two ends of the injection molded rod. The fixing plates each fits against a side wall of a corresponding PET sheet. The injection molded fixing component includes the injection molded rod and the fixing piece. The injection molded rod is configured to connect the PET sheets at the joint where the PET sheets are intercrossed. The fixing plate is configured to prevent the PET sheets from being disengaged from the injection molded rod.

A method and tool for repairing a damaged zone of an aircraft radome, using the actual radome itself as a heating chamber to avoid resorting to an autoclave and the removal of certain parts of the radome which cannot withstand the curing temperature needed for the repair. The method for repairing a radome, wherein the radome comprises a composite panel exhibiting a double curvature forming a dome, the panel comprising at least one damaged zone, comprises the steps of closing an interior space of the panel using a cap to form a repair chamber. The surface of the panel forms the repair chamber containing the damaged zone. Another step is heating the space inside the repair chamber to form a heating chamber allowing the curing expected for repairing the damaged zone.

A production method for a resin molding (1) inserted a 1st plate (10) having many through holes (10a) and a 2nd plate (11) having many through holes (11a), which are arranged in parallel and facing each other during a manufacturing process, comprising a 1st plate process and a 2nd plate process.

The 1st plate process in which, the 1st plate (10) moves to the 2nd plate (11) side from a 1st plate start position (U0) and returns a 1st plate end position (P3) near the 1st plate start position (U0) in a cavity filled with a molten resin (4) kept to a high pressure.

The 2nd plate process in which, the 2nd plate (11) moves to the 1st plate (10) side from a 2nd plate start position (V0) and returns a 2nd plate end position (P4) near the 2nd plate start position in the cavity.

This makes it possible to spread the molten resin (4) to even a shielded area with a reciprocal plate motion. That is, the molten resin (4) is able to pass through holes (10a, 11a) back and forth with the reciprocal plate motion and reach the shielded area finally.

Therefore, the molten resin (4) spread through the surface of the 1st plate (10) and the 2nd plate (11), and a resin wettability of these plates are improved. And as a result, the resin molding (1) strength against a distortion is improved.

A compression molding assembly for molding a honeycomb core, including a plurality of cells defined by a plurality of walls, of a blocker door is provided. The compression molding assembly includes a ram plate comprising a plurality of openings defined therethrough and a plurality of core inserts coupled to the ram plate such that the plurality of core inserts are configured to form the honeycomb core of the blocker door. Each core insert is removably coupled with a respective opening of the plurality of openings such that each core insert is configured to form a respective cell of the plurality of cells.
