The present disclosure relates to composite materials comprising a resin and at least one sheet that comprise optionally cellulose filaments (CF), fillers and optionally reinforcing fibers as well as methods for the preparation thereof. The methods comprise impregnating the sheets comprising the cellulose filaments, fillers and optionally the reinforcing fibers or a stack thereof with resin. The composite materials can optionally comprise at least one other sheet, the at least one other sheet being different from the at least one sheet and comprising fibers chosen from wood pulp, fiberglass, natural fibers and mixtures thereof. The sheet can also be in the form of a panel of a preform.

The present invention relates to a process for laminating components with sheets, in which an adhesive is applied to the surface of the laminating sheet and/or of the component in a grid-like manner, so that, after the sheet and the component are joined, the adhesive is arranged between the sheet and the component, and the regions between the applied adhesive form a channel system that enables the removal of the air that is present between the component and the sheet. The invention further relates to a laminated molded part obtainable by the above-outlined process. The use of an adhesive grid provided between a component and a laminating sheet results in a reduction or prevention of air inclusions when the component is laminated with a laminating sheet.

This invention relates to a polymer composition that is particularly suitable for use in the manufacture of thermoformed articles, which can be biodegraded in industrial composting. This invention also relates to a process for the production of the said composition and articles obtained thereby.

Disclosed herein films and packages formed therefrom for packaging oxygen-sensitive products. The films include a product contact layer comprising COC and catalyst. Introduction of a gas flush including hydrogen gas to a package made from said films helps provide for the catalytic combination of molecular hydrogen and molecular oxygen to remove oxygen from a headspace of the package.

A wind turbine blade including an elongate reinforcing structure, the reinforcing structure comprising a plurality of strips of fibre-reinforced polymer arranged into a stack structure, and at least one adjacent pair of the plurality of strips including an infusion promoting layer, wherein the infusion promoting layer is a fabric comprising a plurality of twisted yarns. The invention is also expressed as a method of assembling a wind turbine blade.

Light fixtures (100, 200, 400, 500, 600, 700) are provided, including a lighting element (10, 20, 40, 50, 60, 70), an oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72) disposed adjacent to or connected to the lighting element, and a control mechanism (14, 24, 44, 64, 74). The control mechanism is in electrical communication with the lighting element (10, 20, 40, 50, 60, 70) and controls an energy output of the lighting element and a temperature of the oriented crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72). Typically, when the control mechanism changes the temperature of the oriented crosslinked semi-crystalline polymer, the shape of the polymer changes. A method of making a light fixture (100, 200, 400, 500, 600, 700) is also provided. The method includes providing a lighting element (10, 20, 40, 50, 60, 70), forming a crosslinked semi-crystalline polymer (12, 22, 42, 52, 62, 72), and disposing the crosslinked semi-crystalline polymer adjacent to the lighting element (10, 20, 40, 50, 60, 70) or connecting the crosslinked semi-crystalline polymer to the lighting element. The method further includes electrically connecting a control mechanism (14, 24, 44, 64, 74) with the lighting element.

A multilayer structure comprising at least one barrier layer, said barrier layer including less than or equal to 12 percent, by weight of the barrier layer, of an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer having a density in the range of from 0.855 to 0.900 g/cm.sup.3; and having a melt viscosity less than 50,000 cP at 350° F. (177° C.); and at least 60 percent, by weight of the barrier layer, of EVOH having from 10 to 32 mole percent units derived from ethylene monomer is provided. Further provided are thermoformed articles made therefrom.

A film comprises an outer heat sealable layer mainly made of a (co)polyolefin with the Vicat softening temperature not exceeding 130° C., at least one heat resistant layer mainly made of at least one polar (co)polymer selected from the group including predominantly aliphatic (co)polyamides and aromatic (co)polyesters, and at least one core adhesive layer from a material capable of adhering both to (co)polyolefins and to polar (co)polymers. The heat resistant layer comprises not less than 15% of at least one predominantly aliphatic copolyamide with the melting temperature not exceeding 205° C. A method comprises the stages of coextrusion, biaxial stretching, annealing and winding up of the resulting film into a roll.

A thermoformable decorative material for an automotive interior includes: a decorative layer including a textile substrate; a digitally printed design disposed on at least one side of the textile substrate and having dispersion ink and/or pigment ink; and an overlay adhesive coating applied to the digitally printed design. The overlay adhesive coating has an adhesive that includes polyurethane and/or polyacrylate.

A multilayer thermoformable film to protect the surface of a workpiece includes an underlayer having first and second faces. The underlayer is made from an adhesive material configured to adhere to the surface of the workpiece by the first face. At least one layer of polymer material is attached to the second face of the adhesive underlayer. The layer of polymer material is resistant to erosion by solid particles and to erosion by liquid particles. It is formed from a polymer material chosen from a polyurethane, a polyether ether ketone and a polyethylene having a very high molecular weight, with a Shore D hardness of between 50 and 65 D. A method of surface protection of the workpiece includes thermoforming the film in a shape adapted to match the shape of at least a portion of the workpiece and applying the film thermoformed onto the surface of the workpiece.
