A multilayer structure is disclosed, comprising: at least one first layer comprising a first polymer film that carries, on a first face, a metal deposit, the first face being a free face of the first layer; and at least one second layer comprising a second polymer film. The second layer is joined, in a plurality of junction zones, to the first layer on the first face carrying the metal deposit, the junction zones defining a region of contact between the first layer and the second layer, the first layer and the second layer forming at least one cell outside the contact region.

An object of the present invention is to provide a core member for a sandwich panel and a method of forming the core member for the sandwich panel which are capable of attaining a desired profile, a desired pattern on its surface, and a desired inner structure in accordance with an application of the sandwich panel. According to an aspect of the invention, there is provided a thermoplastic resin core member interposed between two resin skin sheets comprising a closed hollow portion located to be inside of a desired position in accordance with an application of the sandwiched panel, and it is formed by clamping parison of a molten thermoplastic resin positioned to be between two split molds so as to exhibit a desired profile and/or a surface shape, two surfaces against each of which the molten parison is pressed to form an adhesive surface on which the corresponding resin skin sheet is formed.

Disclosed is a multi-layered composite panel. The multi-layered composite panel comprises at least two sheets of thin plates with continuous waveform patterns having the same pitch and different heights in one direction are overlapped. In the multi-layered composite panel, an adiabatic layer is formed between the overlapping thin plates, diagonal pressing portions, which divide the waveform patterns on the top and the bottom of the thin plates into the unit of triangle-patterned cell by being pressed diagonally to cross each other on the top and the bottom of the thin plates overlapping in the diagonal direction crossing the direction of the waveform patterns, are formed and an undercut portion is formed by pressing the centers of both sides connecting a groove and a ridge of each cell on the top and the bottom of the thin plates with opposite diagonal pressing portions.

A chaff resistant and economically recyclable dunnage tray is disclosed. In one aspect, the dunnage tray includes a base portion formed from a first material and a top portion formed from a second material. The top portion is secured to the base portion, and defines at least one cavity or recess for supporting a machine component. The first and second materials are high density polyethylene (HDPE) materials with the second material including polyethylene elastomers, or plastomers. In one example, the dunnage tray is formed by thermoforming a co-extruded sheet including a first layer corresponding to the bottom structural portion and a second layer corresponding to the elastomer or plastomer portion. In one example, the dunnage tray is formed by thermoforming an extruded sheet to form the base portion and by attaching separately formed top portions with polyethylene elastomers, or plastomers to the thermoformed base portion. This invention provides solutions to chaffing or chipping of polyethylene dunnage trays, control of coefficient of friction and softness to minimize parts from sliding/abrading dunnage surfaces, and eliminates requirements for disassembly of dunnage trays and separation of materials prior to recycling.

A pyramidal geotextile fabric comprising two sets of multi-lobe filament yarns interwoven in substantially perpendicular direction to each other, each of the multi-lobe filament yarns having pre-determined, different heat shrinkage characteristics such that, upon heating, the fabric forms a three-dimensional, cuspated profile. A method of stabilizing soil and reinforcing vegetation comprises the steps of placing a three-dimensional, high-profile woven fabric into soil, wherein the fabric comprises two sets of multi-lobe filament yarns interwoven in substantially perpendicular direction to each other, each of the multi-lobe filament yarns having pre-determined, different heat shrinkage characteristics such that, upon heating, the fabric forms a three-dimensional, cuspated profile; securing the fabric to the ground; and, distributing soil and seed onto the fabric such that the section of ground is quickly revegetated and thereby protected from further erosion.

The invention relates to a multi-chambered, fluid-fillable apparatus, comprising two sheets bonded together to define a plurality of cells between them. In a first aspect, at least one, and preferably both, of the sheets are formed from polyvinyl alcohol. In a second aspect, the sheets are sealed together using both permanent and non-permanent seals. The non-permanent seals are formed to rupture at a predetermined internal pressure in order to dissipate externally applied load.

The present disclosure provides a slipsheet and/or divider sheet and method for making the same, and method for moving and storing containers with use of the slipsheets or divider sheets. The sheets have an imprint or an embossing that provides a raised planar surface. The raised planar surface preferably comprises a plurality of ridges, crowns or crests, which are preferably arranged in a pattern throughout an upper surface of the sheet. To make the sheet, a die can be etched to have protuberances or bumps, and the die is preferably pressed into a sheet of pliable thermoplastic material. The sheet thus made has a plurality of indentations formed by the protuberances or bumps on the die, and the sheet has a planar outer surface comprising a plurality of ridges, crowns and crests between the indentations.

A core member for a sandwich panel and a method of forming the core member for the sandwich panel which are capable of attaining a desired profile, a desired pattern on their surfaces, and a desired inner structure in accordance with an application of the sandwich panel. There is provided a thermoplastic resin core member interposed between two resin skin sheets comprising a closed hollow portion located to be inside of a desired position in accordance with an application of the sandwiched panel, and it is formed by clamping parison of a molten thermoplastic resin positioned to be between two split molds so as to exhibit a desired profile and/or a surface shape, two surfaces against each of which the molten parison is pressed to form an adhesive surface on which the corresponding resin skin sheet is formed.

A layered insulation system comprising one or more layers. A variety of types of layers can be used in conjunction with one another to deliver a range of desired Low-E and/or Low-U insulation properties and/or venting choices. Some types of layers can be foam layers with foam that inhibits heat conjunction interspersed with microparticles and/or nanoparticles that reflect, scatter, abate, and/or negate infrared radiation (IR) wavelengths, including dampening Ideal Model Matrix vibrations to inhibit heat flux through an IR opaque system. Other layers can be Low-E layers, Low-U layers, primarily empty layers, and/or other types of layers.

The present invention relates to a micro-lattice and, more particularly, to an ultra-light micro-lattice and a method for forming the same. The micro-lattice is a cellular material formed of interconnected hollow tubes. The cellular material has a relative density in a range of 0.001% to 0.3%, and a density of 0.9 mg/cc has been demonstrated. The cellular material also has the ability to recover from a deformation exceeding 50% strain.
