Methods for placing an indicia on a composite structure generally include printing the indicia on a first film surface of a coating film, with the coating film being in a partially cured state at the time the printing the indicia is performed, and positioning the coating film on a partially cured composite structure such that a second film surface of the coating film faces and is positioned against a surface of the composite structure, with the second film surface being opposite the first film surface. Finally, the coating film and the composite structure may then be co-cured. Systems for printing an indicia on a composite structure generally include the coating film, a printer configured to print the indicia on the first film surface of the coating film, a securement configured to secure the coating film during printing, and a curing device for co-curing the coating film and the composite structure.

At least some example embodiments relate to a container including a body and a lid. The body includes a base, a side wall, and an interior region at least partially defined by the base and the side wall. The lid includes a lid wall and a skirt that extends from a periphery of the lid wall. The skirt engages the body to retain the lid on the body. The skirt cooperates with the lid wall to define a cavity. The lid is formed from a laminate including a metal layer and a polymer layer coupled to the metal layer. The polymer layer is disposed inside of the metal layer with respect to the cavity. A portion of the body is disposed inside the cavity when the container is in a closed configuration. At least some example embodiments relate to a forming of manufacturing the lid.

Systems and methods for assembling elongate composite structures are disclosed. The systems include a first rigid elongate cure tool defining a first elongate support surface for supporting a first elongate charge of composite material (FEC), a second rigid elongate cure tool defining a second elongate support surface for supporting a second elongate charge of composite material (SEC), and a flexible elongate caul plate. The systems further include a vacuum compaction film, a translation structure, and a vacuum source. Methods according to the present disclosure include positioning a vacuum compaction film, positioning a flexible elongate caul plate, and positioning an FEC. The methods further include positioning an SEC, contacting a region of the FEC with a region of the SEC, sealing the vacuum compaction film, evacuating the enclosed volume to generate an elongate composite assembly, and heating the elongate composite assembly to define the elongate composite structure.

The present invention relates to a hot-melt adhesive resin film having an excellent adhesive force and durability to various adherends such as metal, glass, and plastic, and a production method thereof. More particularly, the present invention relates to a hot-melt adhesive resin film including a first surface layer, a first intermediate layer, a substrate layer having heat resistance, a second intermediate layer, and a second surface layer, which are laminated in this order, in which the first intermediate layer and the second intermediate layer include a resin which is obtained by modifying a copolymer of propylene and 1-butene with maleic acid, and a production method thereof.

A first stack is formed by stacking a first sheet of metal foil, a first prepreg, and a second sheet of metal foil, one on top of another. The first prepreg is thermally cured by thermally pressing these members to make a double-sided metal-clad laminate. Conductor wiring is formed by partially removing the first sheet of metal foil from the double-sided metal-clad laminate to make a printed wiring board. After a third sheet of metal foil has been preheated, the conductor wiring of the printed wiring board, a second prepreg, and the third sheet of metal foil are stacked one on top of another and thermally pressed together. The first insulating layer has a lower linear expansion coefficient than any of the first sheet of metal foil or the second sheet of metal foil does.

A multilayered bullet resistant member, including a three-layered structure formed of a metal-ceramic crack arrest reflecting layer, a fiber-elastomer composite energy absorbing layer and a two-dimensional fabric blunt trauma protective layer sequentially overlapped with each other. The integration of performances of all the components guarantees high strength, hardness and good impact toughness of the bullet resistant member.

A foldable cover article has a total thickness t≤300 μm, which is bendable to a minimum bending radius r≤20 mm without breakage and a pencil hardness HR≥HB. The foldable cover article includes a glass or glass-ceramic substrate with a thickness 5 μm≤t1≤150 μm and a polymer layer and/or a hard material coating with a total thickness 5 μm≤t2≤150 μm. For each 20 mm width of the foldable cover article, when the foldable cover article is broken upon bending along the direction perpendicular to the width, a number of projects with a longest linear extension L≥5 mm is less than 10 and/or a number of projects with a longest linear extension L<5 mm is less than 50.

The invention relates to a method for the production of a laminated core comprising a stack of metallic plates, in which: —a metallic sheet (2, 3) is chosen, having a first main face (4, 8) and a second main face (6, 9) which are coated with a sub-layer comprising at least one material selected from epoxides and polyepoxides, —a layer (12, 20) with a thickness of less than 500 μm of a precursor composition selected from partly epoxides and at least partly cross-linked polyepoxides is placed in contact with said sub-layer, —a layer (16, 22) with a thickness of less than 500 μm of a curing composition comprising at least one crosslinking agent is placed in contact with said sub-layer, —said metallic sheet is punched, —the metallic plates are then superposed to each other.

An article contains a polyurethane or polyisocyanurate foam having a primary surface, an aluminum facer covering, and a primer layer between and attached to the primary surface of the foam and the aluminum facer; wherein the article is characterized by: (a) the primer layer having a concentration of bromine in said primer layer, comprising a primer component and a brominated component, where the primer component and brominated component are the same or different components; (b) the primer layer is free of chlorinated components; and (c) an absence of fibers in the form of fiber mats, fiber fabrics and dispersed fibers between the polyurethane or polyisocyanurate foam and the facer. Such an article shows performance in a fire test equivalent to or better than a laminate article where the bromine is dispersed in the polyurethane or polyisocyanurate foam, at lower total bromine content.
