A method for manufacturing a sandwich panel for a vehicle includes: etching a sheet, which etches one surface of a metal sheet; pressing the sheet, which forms a pattern of a specific shape on the one surface of the metal sheet; laminating a pair of the metal sheets; and performing injection-molding by injecting a plastic resin into the laminated pair of the metal sheets. The method may improve the bonding performance of the sandwich panel, thereby improving the degree of freedom of shape due to the press-molding.

A non-provisioned card having a front side and a back side, and at least one visible surface that is patinated or activated to promote patination.

The invention provides a laminate including a polyimide film and an inorganic substrate, which has a number density of blisters including carbide particles therein of 50/m.sup.2 or less, an average height of blisters of 2 μm or less, a product of the number density of the blisters (blisters/m.sup.2) and the average height of the blisters (μm) of 20 or less. The inventive laminate can be obtained by laminating the polyimide film and the inorganic substrate after sufficiently purifying and cleaning to remove foreign bodies made of inorganic substance therefrom, followed by heat treating the laminate at a temperature of 350-600° C. and then rapidly cooling it to carbonize and reduce the organic foreign bodies, and also to rapidly cool the gas contained in the blisters, which leads to reduced height of blisters.

A composite system for the reinforcement of physical structures includes a plurality of unidirectional fibers arranged with respective longitudinal axes generally parallel to each other over a substantial portion of a length of each unidirectional fiber. The plurality of unidirectional fibers are non-mechanically connected. A resinous material adheres the plurality of unidirectional fibers to each other such that each one of the plurality of unidirectional fiber is adhered to at least one adjacent one of the plurality of unidirectional fibers along a substantial portion of the length of the adjacent one of the plurality unidirectional fibers.

According to one or more embodiments described herein, a laminate glass article may be produced by a method that includes providing a first glass sheet and a second glass sheet, assembling the first glass sheet and second glass sheet into a glass stack, and bonding the first glass sheet to the second glass sheet to form the laminate glass article. In one or more embodiments, an intermediate layer may be positioned between the first bonding surface and the second bonding surface, the first bonding surface and the second bonding surface may be roughened surfaces, or the first bonding surface and the second bonding surface may be chemically treated by vacuum deposition.

The present disclosure relates to a reconstituted wafer- and/or panel-level package comprising a glass substrate having a plurality of cavities. Each cavity is configured to hold a single IC chip. The reconstituted wafer- and/or panel-level package can be used in a fan-out wafer or panel level packaging process. The glass substrate can include at least two layers having different photosensitivities with one layer being sufficiently photosensitive to be capable of being photomachined to form the cavities.

The invention relates to a flexible barrier membrane (1) comprising at least one first layer (2a) of polyurethane, and at least one second layer (20) of material(s), which is incorporated into the first layer (2a) of polyurethane by a modification of at least one surface of the at least one layer of polyurethane. The at least one material of the at least one second layer is selected from the materials including inorganic silicon oxide, organic silicon oxide and a barrier polymer. The invention also relates to a method for producing the flexible barrier membrane (1).
