A method for producing a laminated pane with a functional element with electrically switchable optical properties, includes creating a first stack of layers including a first pane, a first thermoplastic laminating film, a separating film, a second thermoplastic laminating film, a second pane, laminating the first stack of layers while being heated, taking the first pane with the first thermoplastic laminating film off the second pane with the second thermoplastic laminating film, and the at least one separating film is removed from the stack of layers, providing a functional element having an active layer, placing the functional element into the stack of layers, whereby a second stack of layers is formed, laminating the second stack of layers to form a laminated pane, wherein the separating film is detachable residue-free from the first thermoplastic laminating film and the second thermoplastic laminating film.

A composite cover includes a generally rectangular main portion having four main portion edges about a perimeter of the main portion and having opposing top and bottom surfaces defining respective upward and downward directions, and four generally rectangular side portions each contiguous with and extending downward from a respective one of the main portion edges. The main portion and the four side portions generally enclose an interior space and are made of a sandwich structure comprising an interior layer of continuous fiber reinforcements and resin and an exterior layer of metallic foil bonded to the interior layer. A method of manufacturing the cover, having a desired shape generally of a five-walled open box, includes attaching a formed sheet made of metallic foil and having the desired shape onto a shaped composite preform disposed in the desired shape, wherein the shaped composite preform is made of continuous fiber reinforcements and resin.

A flexible coupling for transmitting torque between parts of a transmission shaft system comprises a tubular section of continuous-fibre-reinforced composite material which has been modified to form a living hinge section with reduced bending stiffness to allow flexion of the tubular section. The tubular section may be modified through the provision of a pattern of formations within the living hinge section. The formations may be in the form of apertures and/or recesses in the continuous-fibre-reinforced composite material to create a plurality of living hinges in the material between, in particular slots and/or grooves.

A ball includes a bladder that has a majority weight component of a material of a first material class. The ball includes at least one intermediate layer that is arranged exterior to the bladder and that has a majority weight component of the material of the first material class. The ball includes at least one exterior layer that is arranged exterior to the at least one intermediate layer and that has a majority weight component of the material of the first material class.

A balloon formed from a lamination. The lamination includes a first layer, a second layer, a graphic design and a third layer. The first layer including from about 10 to about 90 wt. % crystalline polyester and from about 10 to about 90 wt. % of a formability enhancer to assist in increasing the polymeric chain flexibility. The formability enhancer has a melting point less than about 230° C. The first layer has a MD and a TD Young's Modulus of at least 10% lower than a crystalline polyester film in the absence of the formability enhancer. The second layer is a metallic barrier layer. The graphic design is printed onto a surface of the metallic barrier layer. The third layer is a sealant layer. The first layer is located between the second and third layers. The balloon contains a gas lighter than air.

The present disclosure relates generally to polymer structures, for example, suitable for construction products. The present disclosure relates more particularly to a thermoplastic construction product including a coextruded layer structure having a base layer including a first thermoplastic material, an outer layer including a second thermoplastic material, and an infrared-reflective intermediate layer that is coextruded with the base layer and the outer layer and is disposed between the base layer and the outer layer. In some embodiments the intermediate layer has a thickness of at least 30 micrometers. In some embodiments the infrared-reflective intermediate layer includes a reflective pigment dispersed in a matrix of one of the first thermoplastic material or the second thermoplastic material.

A multilayer film bonded to a base fabric includes a first layer bonded to the base fabric; and a second layer disposed on the first layer. The first layer, the second layer, or both includes a thermoplastic elastomer. The thermoplastic elastomer is at least one selected from the group consisting of a polyester-based elastomer, a polyurethane-based elastomer, and a polyamide-based elastomer.
