A method of fabricating a panel includes laying up a first laminate on a tooling surface, laying a first layer of thermoplastic on an inner surface of the first laminate, laying a large cell carbon core on the first layer of thermoplastic, laying a second layer of thermoplastic across the large cell carbon core, laying a second laminate on the second layer of thermoplastic, creating a sealed core pocket by bonding the edges of the first and second layers of the thermoplastic surrounding a perimeter of the core, increasing pressure within the core pocket, increasing pressure on the outer surface of the second laminate, heating the panel to a desired curing temperature, and maintaining the increased pressures and temperature for a desired curing duration.

The present invention relates to an ionomer resin, comprising: a (meth)acrylic acid unit (A); a neutralized (meth)acrylic acid unit (B); and an ethylene unit (C), wherein the total amount of the unit (A) and the unit (B) is from 6 to 10 mol % based on the entire monomeric units constituting the ionomer resin, and wherein the amount of a salt composed of a strong acid and a strong base in the ionomer resin is from 1 to 400 mg/kg.

A membrane assembly for vacuum bagging includes an elongate sheet of flexible material capable of being rolled up into a cylindrical configuration and unrolled from the cylindrical configuration into a flattened-out configuration, a bistable tape spring attached to or captured by the elongate sheet, and an inflatable tube attached to or captured by the elongate sheet. The bistable tape spring has a first stable state which is a straightened-out state, a second stable state which is a rolled-up state, and a transition state between the first and second stable states. The inflatable tube is sealed at one end and has an orifice at the other end for admission of a fluid therethrough for inflation of the inflatable tube.

A lamination process is disclosed. The process is useful for silicone based lamination adhesive compositions, in particular those which cure at or around room temperature.

The present invention relates to a luminous vehicle sunroof that includes a first glazing with first and second main faces, a light-emitting element such as an OLED or QLED and a collimating optical system with one or more optical films.

This disclosure includes sandwich composites comprising fiber-reinforced laminates. The disclosure further includes one or more film adhesives between a core and the fiber-reinforced laminates.

A method of manufacture (200) of an inflatable product with an attachable foam finish is described that includes modifying (202) a molecular structure of at least one foam sheet; gluing (206) a flexible, glueable or weldable material onto the modified at least one foam sheet to create a bonded structure; and gluing (220) the bonded structure to the inflatable product.

A method for manufacturing an optical article including the following steps: a. providing a first substrate with a main surface, b. depositing a second substrate on the main surface with an adhesive layer so that the space between the first substrate and second substrate is filled by the adhesive layer, c. curing the adhesive layer to induce a polymerization of the adhesive layer, wherein a tension step takes place after steps a. and b., and before step c., the tension step including applying symmetrically a tension, preferentially with a central symmetry, preferentially a radial isotropic tension or an ortho-distributed symmetrical tension, on the edges of the second substrate sensibly in a tension plan parallel to a plan representative of the main surface.

A lamination device for laminating a photovoltaic stack on a profiled metallic panel, the lamination device including a lid covered on its underside with an upper flexible pressure membrane so as to form an airtight upper chamber that may be ventilated or evacuated and/or including an upper heating device whose bottom side has a crenellated profile, the device also including a chassis covered on its top with a lower flexible pressure membrane so as to form an airtight lower chamber that may be ventilated or evacuated and/or including a lower heating device whose upper side has a cross-section which differs from the crenellated profile of the bottom side of the upper heating device, wherein the lid is capable of sealably laying on the chassis so that the cavity thus formed is airtight and may be ventilated or evacuated. A corresponding process is also provided.

This invention relates to a method for forming a panel or skin for a hollow core door, a method of manufacturing a said door, a hollow core door, a panel, and an apparatus for forming a panel and skin for a hollow core door. The method comprises providing a substrate comprising a patterned groove therein; applying a laminating material on the substrate with an adhesive. The method then comprises sealing the substrate with the laminating material thereon in a chamber and providing at least one deformable membrane adjacent the laminating material; removing air from the chamber wherein under vacuum, the deformable membrane deforms into the groove thereby urging the laminating material into the groove; heating the laminating material to facilitate bonding thereof to the substrate; and allowing the substrate with the laminating material thereon to cool so as to form a panel with the laminating material bonded thereto.
