Abstract:
The present invention relates especially to an intermediate material comprising, or even constituted exclusively by, an array of individualised ribbons, each ribbon being composed by a tape of unidirectional reinforcing fibres associated, by adhesion, on each of its faces with a veil of thermoplastic fibres, characterised in that the ribbons are disposed in successive layers, in such a way that the ribbons of two successive layers are superposed with or without crossing but without interlacement, the bond between a ribbon and the ribbon or ribbons with which it is superposed being ensured by adhesion, and in that in each layer the ribbons are disposed substantially parallel to each other over at least the major part of their length, while being independent and spaced from each other and in that the ribbons of at least two layers extend in two different directions.
Abstract:
A method is provided of making form fill and seal (FFS) bag formed at least in part from an open mesh material that includes filaments that intersect one another. At least some of the filaments are composite filaments having a carrier portion of a relatively high melting point and a bonding portion of a relatively low melting point, the bonding portion of each composite filament being thermally bonded to other filaments at points of intersection. The material may be a non-woven fabric that contains at least two layers of weft filaments that may be bordered on one or both sides by a layer of warp filaments. When compared to other open mesh materials, the open mesh material disclosed herein has a superior combination of some or all of high strength, light weight, high dimensional stability, and openness.
Abstract:
The invention relates to a substantially laminary manufacture comprising 2 substantially laminary layers in contact, wherein the layers comprise a woven, hydrophilic material.
Abstract:
Improved containment mats and systems of containment mats may include multiple adjoining mats with a top surface and a bottom surface. The multiple mats may provide a modular structural mat system that may be installed at a drill site, with multiple mats placed adjacent to each other with a lap joint connecting adjacent mats. A geotextile may be used to cover the lap joints and a coating applied to the geotextile. Such a system may provide containment of potential spills, a reliable working surface for drilling operations, and relatively fast and less expensive installation.
Abstract:
Thermal rectifiers using linear nanostructures as core thermal conductors have been fabricated. A high mass density material is added preferentially to one end of the nanostructures to produce an axially non-uniform mass distribution. The resulting nanoscale system conducts heat asymmetrically with greatest heat flow in the direction of decreasing mass density. Thermal rectification has been demonstrated for linear nanostructures that are electrical insulators, such as boron nitride nanotubes, and for nanostructures that are conductive, such as carbon nanotubes.
Abstract:
A method of manufacturing a hollow core door is disclosed, as well as a corresponding hollow core door. The method includes the steps of providing a solid flat door skin, moisturizing the flat skin, applying a conditioning resin thereto, pre-heating the flat door skin, and thereafter pressing the flat door skin between a pair of heated platens in a press in order to reform the flat skin into a molded skin including a plurality of panels defined therein. The press continuously closes in order to reform the flat skin into the molded skin, with the rate of press closure being a function of the determined hardness of the flat skin to be reformed. The resulting door skins have an improved bond strength, and are efficiently manufactured.
Abstract:
Aspects of the present disclosure are directed to apparatuses and methods involving nanowires having junctions therebetween. As consistent with one or more embodiments, an apparatus includes first and second sets of nanowires, in which the second set overlaps the first set. The apparatus further includes a plurality of nanowire joining recrystallization junctions, each junction including material from a nanowire of the first set that is recrystallized into an overlapping nanowire of the second set.
Abstract:
A sheetlike composite material including at least one layer A of a nonwoven thermoplastic fibre web or a thermoplastic film, and at least two unidirectional oriented-fibre layers B and B′, the layers B and B′ having a bidirectional fibre orientation. The layers are not only needled but also stitched to one another.
Abstract:
A laminar sheet and building block include re-sawed mini-sheets from laminar plank or beam starting material wherein the mini-sheets are oriented transversely to one another and vertically stacked and adhered. A system and methods for their manufacture also are also disclosed. The building block features a unique surface and edge appearance and is denser, more durable, more sag- and warp-resistant, and less expensive than conventional building blocks.
Abstract:
A reinforcing drywall tape and a method of making the same, the tape having a greige combined with a laid scrim constructed in situ on the greige and bonded to the greige by a resin coating, and a pressure sensitive adhesive fully covering an inward facing surface of the greige wherein the greige is adapted for adherence to drywall sections.
