A passive electrical article including a dielectric layer having a nonwoven material.

A method of manufacturing at least one structural panel (20) for an engineering structure comprises conveying a layered structure (40) through a roller assembly comprising at least one pair of heating rollers (50) and at least one pair of cooling rollers (52), where the cooling rollers are at a lower temperature than the heating rollers. The layer structure comprises a thermoplastic foam layer 24 and at least one skin layer (22). The heating rollers 0 heat the skin layer (22) to melt at least part of the foam layer (24) adjacent to the skin layer (22) and bond the foam layer (24) to the skin (22). The cooling rollers (52) cool the layered structure (40) so that the thermoplastic resolidifies, retaining its bond with the skin to form the bonded panel (20). This approach greatly reduces manufacturing costs for structural panels.

There is provided a polarizer excellent in heat resistance. A polarizer according to an embodiment of the present invention includes a resin film containing iodine, wherein an end portion of the resin film has formed therein a high-concentration portion having a concentration of a substance that forms a counter ion of iodine higher than that of another portion.

The invention relates to a shield comprising: a thermo-compressed porous three-dimensional shell based on glass fibers, the fibers being joined together by a binding agent. The shield includes a foam-based inner spring layer, and additionally has the following features: the foam layer is produced by reaction injection molding (RIM), the layer overmolding the shell. The shell has a porosity arranged in order to enable the foam to penetrate a fraction of the thickness of the shell, so as to create a leaktight skin the binding agent is based on polypropylene. The shell comprises between 45 and 55% by weight of glass fibers.

An object of the present invention is to create, from a titanium alloy and an FRP prepreg, a composite of a titanium alloy and an FRP material that is suitable for bolt fastening. The composite can bring out excellent characteristics in CFRP members in mobile electronic-electric devices, mobile equipment, medical instruments, marine devices and the like. It has been found that titanium alloy having a special constant surface shape adheres strongly with an epoxy adhesive. In a composite obtained using this technique to integrate a titanium alloy member as a cover material and a CFRP material, the metal alloy portion deforms and disperses locally strong forces so that the CFRP material is not damaged, even when the composite is assembled to another metal member through bolt-fastening. As a result, the composite is expected to be effective for applications in mobile equipment or mobile device casings, where lightweightness, corrosion resistance, toughness and ease of assembly are required.

A system and method for bonding a porous structure to at least one other structure is provided, including an inner adhesive member adapted to be positioned adjacent the porous structure and having a melting temperature, and an outer shrink wrap member positioned over and at least partially enclosing the inner adhesive member, the outer shrink wrap member having a recovery temperature, wherein the melting temperature is higher than the recovery temperature.

A flexible composite suitable for use in a knife, pick, bullet and fragment-resistant article comprising (i) a first zone comprising fabric but no resin, the first first zone comprising from 10 to 90 percent of the total thickness of the composite, (ii) a third zone comprising an elastomeric or thermoplastic resin but no fabric, the third zone comprising from 0 to 50 percent of the total thickness of the composite and (iii) a second zone, located between the first and third zones, comprising fabric and an elastomeric or thermoplastic resin, the second zone comprising from 10 to 90 percent of the total thickness of the composite.

A method is provided for producing a glass ceramic element with a patterned coating is provided. The method includes: providing a glass ceramic element with a coating which is at least partially light-blocking and preferably opaque in the visible spectral range; irradiating the glass ceramic element with a pulsed laser beam on the face provided with the coating so that the coating is removed by ablation; during irradiating the laser beam is directed over the surface of the glass ceramic element so that a portion of the coating is removed which has a greater lateral extent than the diameter of the laser beam; and once the coating has been removed, irradiating the glass ceramic with the laser in the region where the coating has been removed, thereby optically modifying the glass ceramic in the irradiated region.

An article comprising a first component having a first electrically conductive surface and a second component having a second surface. An adhesive composition comprising a cured polymerizable ionic liquid is disposed between the first electrically conductive surface and second surface and joins the first component to the second component. The polymerizable ionic liquid comprises an acid functional monomer and the conjugate acid of an imidazole compound. The effort required to separate the first component from the second component, as measured by work of adhesion per surface area, is reduced by application of a DC electric potential across the adhesive composition.
