The invention provides low solar transmittance coatings that have particularly low solar transmittance. The coating includes three infrared-reflection film regions, which may each comprise silver. In some cases, the coating is incorporated into a laminated glass assembly.

A method for bonding infrared transmitting glasses into an optical element without interlayer voids by stacking at least two different infrared transmitting glasses inside a vessel where each glass has a different refractive index, a different dispersion, or both, and where the glasses all have similar viscosities, thermal expansion coefficients, and glass transition temperatures; placing a weight on top of the stack; applying a vacuum to the vessel; applying an isostatic pressure of at least 1500 psi; and after releasing the isostatic pressure, annealing at a temperature within 10 C. of the glass transition temperature at a pressure between 0 and 1000 psi. Applying the vacuum, applying the isostatic pressure, and annealing are done sequentially and with no intermediate transitions to ambient temperature or pressure. Also disclosed is the related optical element made by this method.

The invention relates to a PVC composite flooring, comprising PVC base material and decorative board with alumina hot-pressed on the surface. The invention also relates to a process of preparation for the PVC composite flooring, comprising bonding the PVC base material and the decorative board with alumina hot-pressed on the surface using a hot-melt adhesive. The PVC composite flooring of the present invention is excellent in abrasion resistance, has remarkably improved resistance to indentation, is particularly excellent in compression stability.

Fabrication of a multi-layer X-ray source is disclosed using bulk structures to fabricate a multi-layer target structure. In one implementation, layers of X-ray generating material, such as tungsten, are interleaved with thermally conductive layers, such as diamond layers. To prevent delamination of the layers, various mechanical, chemical, and/or structural approaches may also be employed.

The present invention relates to a band for joining a polyester textile, and to a method for obtaining same, wherein the textile has a printed design, such that the band provides a means for joining the textile and an attachment frame. Advantageously, the proposed band has the same composition as the textile, which facilitates the recycling of the assembly and enables the waste to be reused. For this purpose, the band is formed by a needle-punched nonwoven polyester fabric comprising polyester fibres and bicomponent polyester fibres and has a polyester film on at least one of the surfaces thereof. The claimed invention is of special interest for use in visual communication solutions, such as decorative panels or advertisements at points of sale, in retail, at events and at stands, among others.

A method of preparing a plant-based prepreg is provided. The method includes adhering a plurality of plant fibers or strands to form a mat or sheet, enclosing the mat or sheet within a vacuum bag having an inlet and outlet, applying a vacuum pressure to the vacuum bag, passing a resin through the inlet to infuse the resin into the mat or sheet; and removing the vacuum bag to provide the plant-based prepreg. A laminated composite material may be prepared by layering a plurality of plant-based prepregs and applying heat and compression to the layered plant-based prepregs to provide the laminated composite material.

The present disclosure is directed to a position-controlled lamination tool or press that includes an array or plurality of pressure sensors and an array or plurality of heating/cooling elements or components, which may be coupled together, for preventing or reducing laminating film or material bleed out and improving thickness variation performance. The pressure sensors may provide a controller, which is coupled to the lamination tool, with real-time feedback on any thickness variations across a substrate panel and the controller may adjust the temperature output of the heating and cooling elements to locally modify the viscosity of the laminating material in one or more regions of the substrate panel to either decrease or increase the flowability of the laminating material.

Laminate BMG-fiber feedstock and parts made from one or more fiber layers and two or more bulk metallic glass (BMG) layers are described herein. The hot formed BMG-fiber laminates have vastly superior strength, ductility and use parameters as compared to the fiber or BMG alone as well as to conventional metal-fiber weaves. Methods of formation for both the BMG-fiber laminate and for near-to-net parts made therefrom are also provided.

A laminate material having a decorative appearance has a plurality of layers that are bonded together with at least one of the layers having a first orientation. A portion of at least one of the layers adjacent to an exterior surface of the material is deviated into a second orientation differing from the first orientation. The exterior surface of the material is substantially flat, thereby revealing multiple layers at the exterior surface. Each layer may comprise a sheet that is pre-impregnated with a thermosetting resin. A form having a surface feature may be pressed into the exterior surface of the material while the layers are bonded together to deviate a portion of at least one of the layers adjacent to an exterior surface of the material into the second orientation. The invention also includes a method of generating a laminate material having a decorative appearance.

A fuel cell manufacturing method and a fuel cell manufacturing device are provided in which it is possible to heat, in a localized manner, sections for which heating is desired. In this fuel cell manufacturing method, a laminate is obtained by stacking a membrane electrode assembly and a separator that has an adhesive disposed therebetween. Coils are provided adjacent a site of the laminate to be heated. Preferably, coils are disposed on opposite sides of the site in the stacking direction of the membrane electrode assembly and the separator such that current flows in the same direction as directions intersecting the stacking direction. The site to be heated is subjected to induction heating by passing current through the coils.
