A nonwoven fabric sheet exhibiting high flame shielding performance, heat insulating property, and wear resistance is described, where the nonwoven fabric sheet is fabricated and includes at least one fire barrier layer formed of a web containing a non-melting fiber A having a high-temperature shrinkage rate of 3% or less and a thermal conductivity conforming to ISO22007-3 (2008) of 0.060 W/m.Math.K or less and in which the fire barrier layer is coupled with a scrim layer containing a carbide-forming heat resistant fiber B having a LOI value conforming to JIS K 7201-2 (2007) of 25 or more.

To provide a polishing pad capable of sufficiently polishing, in polishing of an object to be polished having at least one of a projection portion and a recessed portion on the surface, a portion near the projection portion or the inner surface of the recessed portion of the surface of the object to be polished. The polishing pad has a piloerection portion (1) in which a plurality of fibers (12) having a length of 2 mm or more are raised on the surface of a base (11), in which the mass of the fibers (12) is 250 g/m.sup.2 or more. The polishing pad is used for polishing an object to be polished (2) containing metal, an alloy, or a metal oxide material and having at least one of a projection portion (21) and a recessed portion (22) on the surface.

A manufactured composite comprising synthetic turf and impermeable geomembrane is used in a single-layer capping system as the single layer to provide permanent, impermeable and functional aesthetic cover for a job site. During installation of composite pieces at a job site, an edge portion of a tufted section of a second composite piece is overlaid onto an edge untufted section of the first composite piece already laid and anchored over foundation soil to form a reinforced overlapping seam, through which the two composite pieces are physically and permanently joined together. As composite pieces are joined together, the continuity of synthetic grass and the continuity of impermeability are extended and realized over the entire site to form permanent, impermeable and functional aesthetic cover for a job site.

A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate has a thickness larger than one half of the thickness of the entire panel, and the substrate at least includes two layers, where the two layers each include thermoplastic material. A first one of the two layers further includes at least 60 percent by weight of filler materials and a second one of the two layers includes less fillers or is not filled, and is situated above the first one of the two layers.

A photovoltaic apparatus is provided including a back sheet and a photovoltaic device disposed over the back sheet. The photovoltaic device includes an array of photovoltaic cells extending in a first direction; and a plurality of serial interconnects having a length that extends in a second direction, wherein each serial interconnect is disposed between and electrically connects consecutive photovoltaic cells of the array. The photovoltaic apparatus further includes a front sheet disposed over the photovoltaic device, the front sheet having a plurality of structures, wherein each structure has one or more edges aligned with one of the serial interconnects.

A method for manufacturing an acoustic absorption structure including an acoustically resistive layer, a cellular structure, a reflective layer and a plurality of acoustic elements positioned in cavities produced in the cellular structure. This method comprises steps of depositing fiber plies on a contact surface of the cellular structure, fitting a flexible jacket which covers a stack composed of the acoustically resistive layer, the cellular structure and the fiber plies, which is tightly linked with the deposition surface all around the stack, consolidating the fiber plies to form the reflective layer and the fixing thereof on the cellular structure, with a caul plate being inserted between the fiber plies and the flexible jacket during the consolidation step.

An eversion liner for lining a pipe includes an impermeable outer portion, inner and outer strength portions inside the impermeable outer portion, and a middle portion including at least one felt layer radially between the inner and outer strength portions. At least one of the inner and outer strength portions is formed from a unitary sheet of strength material that includes parallel chopped strands of fiber. The longitudinal edge margins of the sheet of strength material are positioned in overlapping engagement and joined together by joining structure. The parallel chopped fibers can be oriented transverse to the length of the liner. The joining structure can prevent reduction in a width of the overlapped edge margins as the liner expands during eversion.

A rate-sensitive protective apparel including an outer fabric shell, first and second sealing material layers positioned within the outer fabric shell, and a shear thickening fluid core disposed between the first and second sealing material layers is provided. The sealing material layers have fibers extending towards the apparel interior and enmeshing the shear thickening fluid core, and the shear thickening fluid directly contacts with the sealing material and the fibers.

A panel including at least a substrate of thermoplastic material and a top layer with a printed decor and a translucent or transparent wear layer. The substrate includes three layers, including a lowermost layer, a central layer and an uppermost layer, all made from thermoplastic material, where the thermoplastic material of the central layer is more rigid than the thermoplastic material of the lower most layer and the uppermost layer.

A V-ribbed belt includes a compression rubber layer containing a vulcanizate of a rubber composition, a tension member, and a tension layer, and has a side part of the compression rubber layer being a ground surface coming into contact with pulleys, and a bottom part of the compression rubber layer being a non-ground surface not coming into contact with pulleys. The V-ribbed belt has, on a surface of the bottom part, a composite layer containing a fiber assembly and a vulcanizate. The fiber assembly contains a heat-resistant fiber which is not melted at a vulcanization temperature of the rubber composition and has a weight per unit area of 25 g/m.sup.2 or less. The vulcanizate of the rubber composition impregnated among fibers of the fiber assembly.
