A method for manufacturing a panel including a reinforcement sheet having the steps of: providing a first layer of thermoplastic material, providing a reinforcement sheet, laying the reinforcement sheet and the first layer onto each other, applying a second layer of thermoplastic material on top of the reinforcement sheet at a side facing away from the first layer, at least partially melting the thermoplastic materials of the first layer and the second layer, adhering the at least partially melted first layer, the at least partially melted second layer and the reinforcement sheet to each other so as to form the panel. Additionally, the reinforcement sheet and the first layer are adhered to each other by pressing them together after at least partially melting the thermoplastic material of the first layer, but before applying the second layer of thermoplastic material onto the reinforcement sheet.

Provided are an article including a joint portion of a fluororesin having sufficient strength, and a method of producing the same. The article includes a joint portion including: a porous first layer of a first fluororesin; a second layer of a second fluororesin having a melting point lower than a melting point of the first fluororesin; and a non-porous third layer formed between the first layer and the second layer, the non-porous third layer including the first fluororesin.

Structural panels and methods of making composite material for such structural panels may include applying a resin to a nonwoven fibrous web, where the nonwoven fibrous web includes a combination of glass fibers and polymer fibers. The web may be dried at a first stage temperature at or below a curing temperature of the resin for a time sufficient to substantially dry but not substantially cure the resin. The web may be laminated at a second stage temperature sufficient to fully cure the resin to produce a composite material. The second stage temperature may be above the melting point of the polymer fibers, and the resin may cause the composite material to retain a substantially rigid shape upon completion of the laminating operation.

The invention relates to a method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned between at least two metallic layers. At least one of the metal layers is shaped into a three dimensional layer, and the metal layers are in direct mechanical contact to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions in a subsequent manufacturing process.

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 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.
