Abstract: A honeycomb core includes a first wall, a second wall, and a conductor disposed between the first wall and the second wall. The first wall and the second wall define a cell through which the conductor extends. A sandwich panel includes an upper skin, a lower skin, and a honeycomb core adhesively bonded to the upper skin and the lower skin. The honeycomb core includes a first wall and a second wall defining a cell. The sandwich panel further includes a conductor disposed between the first wall and the second wall and extending through the cell.

Abstract: The luminous element includes a luminescence lamination, a second transparent oxidative conducting layer and a composite conducting layer. The composite conducting layer includes first transparent oxidative conducting layer and a metal layer. The second transparent oxidative conducting layer is positioned between the metal layer and luminescence lamination the second transparent oxidative conducting layer forms good ohmic contact with the luminous element and with metal layer. Thus, the metal layer will not be influenced by interfusion so as to maintain good light transmissivity and raise luminous efficiency of luminous element.

Abstract: A honeycomb structured body including a plurality of cells that are placed in parallel with one another in a longitudinal direction with a cell wall therebetween, and a sealing portion sealing either one of the end portions of the cells. The honeycomb structured body has a porosity of at least about 70% and at most about 95% and having a length about 0.2 to about 0.9 times a diameter thereof, where the length is in the longitudinal direction of the honeycomb structured body, and the diameter is of a cross-section perpendicular to the longitudinal direction of the honeycomb structured body.

Abstract: A brazing sheet of aluminum alloy composed of a core material and a first brazing filler metal covering one surface of the core material. The core material contains as an essential component 0.2-1.0 mass % of Cu and as optional components at least one species of no more than 1.5 mass % of Si, no more than 1.8 mass % of Mn, no more than 0.35 mass % of Ti, and no more than 0.5 mass % of Mg, with the remainder being Al and inevitable impurities. The first brazing filler metal has a liquid phase ratio (X %) at 600° C. and a thickness (Y ?m) such that X and Y satisfy the following relationship: (1) 30?X?80, (2) Y?25, and (3) 1000?X×Y?24000. The brazing sheet provides good brazeability and maintains high corrosion resistance after brazing on the surface cladded with the brazing filler metal.

Abstract: Method for chemical bonding of fiberglass fibers to steel surfaces to prepare the steel for bonding with carbon composite material. This fiber-bonding step greatly increases the strength of the subsequent metal-composite bond. The fiberglass fibers which are chemically bonded to the steel provide a high surface area interface to entangle with carbon fibers in the composite component, and thereby inhibit crack formation on the boundary surface between the steel and composite components when they are bonded together.

Abstract: A steel sheet pile in double-T form includes a web and two flanges, in which each flange has an inner side facing the web, an outer side facing away from the web, and two longitudinal edges, and also coupling means for a connection profile along at least one longitudinal edge of at least one flange. In a first embodiment, the coupling means are formed by a groove which extends in the outer side of at least one flange along at least one longitudinal edge.

Abstract: A planar two material structure comprising a first material having a coefficient of thermal expansion greater than zero and a second material having a second coefficient of thermal expansion greater than zero. The two materials structurally combined in a plurality of repetitive for or six sided unit cells having a combined coefficient of thermal expansion less than the coefficient of thermal expansion of either material alone.

Abstract: A slide member provided with an Al-based alloy layer including Si and having a first contoured surface having first planar surfaces and first convexities consisting of Si particles protruding from the first planar surfaces; an intermediate layer that coats the Al-based alloy layers an overlay that coats the intermediate layer; wherein 90% or more of the Si particles protruding from the first planar surfaces are configured to have a predetermined particle diameter of 2 ?m or less, the Si particles having the predetermined particle diameter being distributed in the Al-based alloy layer with a distance between centers of gravity of the Si particles having the predetermined particle diameter averaging 6 ?m or less, and wherein the overlay has a second contoured surface having second planar surfaces and second convexities conforming with the first planar surfaces and the first convexities of the first contoured surface.
