A method for creating a honeycomb core having venting pathways includes controlling where a resin is applied to sheets to form the venting pathways. A honeycomb substrate is then formed from the sheets.

Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

The invention relates to a multi-layer element which can be illuminated with edge lighting and optionally also with backlighting, an which has a stone-like appearance. Alongside the stone layer, layers made of a thermoplastic material are also provided. The structure is not only an attractive design element with day/night design for building interiors and facade construction, but it can also be used in many ways in the automotive sector.

What is described as a multilayer body which can be illuminated by means of edge lighting and optionally also by backlighting, and which has a stone look. As well as the stone layer, layers of thermoplastic material are provided, with a translucent dark-colored layer provided on the reverse side with respect to the stone layer. The structure is a pleasing design element with day/night design not just in the configuration of building interiors and facades, but can also be used in a versatile manner in the automotive sector.

A coating composition is described that can be completely biodegradable and well suited for use in laminating films to substrates. The coating composition contains a biodegradable polymer, such as a polyvinyl alcohol polymer. The coating composition can be applied to a biodegradable film and then adhered to a substrate, such as a paper substrate.

A floor mat for use in a commercial aircraft application includes a base carpet-like section made of a fire rated material. A backing film layer is mounted to a bottom of the base carpet-like section. This mounting may be made, for example, using an intervening adhesive layer or through a direct attachment using an inherent adhesive property of the backing film layer. The backing film layer (and any adhesive layer that is used) is made of a fire retardant material. The base carpet-like section is porous and absorbent, and the backing film layer provides a moisture barrier as well as an anti-slip feature.

A method of forming a dry floor assembly includes cleaning an upper layer with methyl ethyl ketone (MEK) prior to bonding the upper layer to a carbon wicking layer. Said cleaning removes release agent from the upper layer. The method also includes bonding the upper layer to the carbon wicking layer after said cleaning.

The invention relates to a multilayer wood composite block comprising a plurality of wood layers, wherein at least 5 wood layers of the plurality of wood layers have a layer thickness of 0.05 to 1 mm; a plurality of plastic layers, wherein at least 5 plastic layers of the plurality of plastic layers consist of translucent and/or transparent plastic and have a layer thickness of 0.05 to 1 mm; and a plurality of adhesive layers; wherein the wood and/or plastic layers are arranged in a superimposed manner; and wherein the adhesive layers are arranged between successive wood and/or plastic layers and bond them together; and a multilayer wood veneer.

In accordance with an embodiment, a noise reduction device includes a housing; and a slit located inside the housing and having a unit cell located therein, the unit cell comprising a sound absorbing layer configured to absorb noise generated from a sound source inside the housing, and a meta-material panel layer located on one surface of the sound absorbing layer, the meta-material panel layer comprising a sound meta-material.

An electrode structure disposed on the outer circumference of a core metal of a steering wheel provided in a vehicle includes an insulator and a first electrode disposed on a first surface of the insulator that is on an opposite side of the insulator relative to a surface of the insulator that faces the core metal of the steering wheel. The insulator includes an engagement portion that engages a first engagement-target portion included in the core metal.
