A composite structure comprises stacked sets of laminated fiber reinforced resin plies and metal sheets. Edges of the resin plies and metal sheets are interleaved to form a composite-to-metal joint connecting the resin plies with the metal sheets.

A composed element includes at least two panel-shaped elements, which each have an edge zone in which coupling means are present in a profiled part respectively extending in the longitudinal direction of the respective edge zone, and each including an end face extending transversely to the respective edge zone. The profiled parts allow the coupling of the panel-shaped elements together in an interlocking manner. At least one of the panel-shaped elements includes an arrangement which hides from view at least a portion of the profiled part formed at the pertaining edge zone at the location of the end face.

A hermetic seal between an optical element and a metal mount or housing using a fluoropolymer. The fluoropolymer is dispersed along the interior edge of the metal mount. The metal mount and fluoropolymer are then heated to a temperature exceeding the melting point of the fluoropolymer. Once heated the optical element is pressed into the metal mount and allowed to cool. The metal mount, optical element and thickness of fluoropolymer are sized to provide an interference fit between the metal mount and optical element.

The embodiments described herein provide for lightning protection in aircrafts constructed with Carbon Fiber Reinforced Plastic (CFRP). In one embodiment, the apparatus includes a first Carbon Fiber Reinforced Plastic (CFRP) panel, a second CFRP panel that overlaps with the first CFRP panel in a vertical direction, and a fastener to join the first CFRP panel with the second CFRP panel, the fastener extending in the vertical direction in an area where the first CFRP panel and the second CFRP panel overlap. The apparatus further includes a plurality of electrically conductive pins in each of the first CFRP panel and the second CFRP panel, wherein the pins extend in the vertical direction proximate to the fastener to electrically connect the first CFRP panel and the second CFRP panel in the area where the first CFRP panel and the second CFRP panel overlap.

Described is a venting device including a flexible outer covering defining an outer surface and an inner surface, a set oc of helicoidal venting strips, and a set of helicoidal buffers. The outer covering has a first end and a second end and a longitudinal axis therebetween. Each venting strip is anchored to the inner surface and extends substantially between the first end and the second end and the set of venting strips is arranged substantially helicoidal and defines a set of helicoidal seams therebetween. The set of helicoidal buffers includes a buffer covering an inner opening of each seam of the set of helicoidal seams where eachbuffer is configured to shield the inner opening of the corresponding seam from penetration and each buffer is anchored to at least one of the outer covering and a neighbouring venting strip of the set of venting strips.

A glass composite includes a first glass member and a second glass member. The first glass member and the second glass member are at least partially connected with each other at the surfaces. The glass composite has a light transmittance not lower than 95% of the light transmittance of the one, with the lower light transmittance, of the first glass member and the second glass member.

Disclosed herein is a laminated structure including a first layer covering a substrate and a raised portion existing on the substrate, and a second layer covering the first layer, in which a first seam is formed inside the first layer, starting from a part at which the raised portion rises from the substrate or a vicinity of the rising part as a start point, a second seam is formed inside the second layer, starting from a part at which the first layer positioned above the substrate rises or a part of the second layer corresponding to a vicinity of the rising part as a start point, and the first seam and the second seam are discontinuous.

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

A gas barrier material includes an atomic sheet, such as graphene and/or an analog of graphene. The gas barrier material can be arranged as part of a component, such as a container or other vessel, to limit the flow or permeation of gas through the component. Where the component is a container or part of a container, the gas barrier material may be formulated and arranged to limit or prevent gas ingress or egress with respect to the internal volume of the container. The atomic sheet offers improved gas barrier properties compared to traditional polymeric barrier materials and is particularly useful in applications where it is desired to limit permeation of small gas molecules such as helium, such as airships or other lighter than air vehicles.
