The present invention relates to a method for manufacturing a glass sheet composite including two or more sheets and an intermediate layer between at least a pair of sheets of the sheets, the pair of the sheets consisting of a sheet 1A and a sheet 1B, at least one of the sheet 1A and the sheet 1B being a glass sheet, and the method including: applying a liquid agent for the intermediate layer and a sealant to at least a part of a main surface of the sheet 1A; bonding the sheet 1B to the main surface of the sheet 1A to which the liquid agent for the intermediate layer and the sealant are applied to obtain a laminate; and subjecting the laminate to reduced pressure.

One of the problems is the reduction in interior areas and surfaces where various types of devices can be mounted. To address this issue more and more of these devices are being integrated with the glazing. Laminated glazing is especially suitable for thin devices. Today, laminated glazing is produced with heating elements, antennas, lighting, touch sensors, RFID, electronic blinds and other types of devices integrated as a permanent part of the glazing. The invention comprises an automotive laminate with a thin integrated electroacoustic transducer integrated in the glazing.

Systems and methods are presented for acoustic dampening in a rotating machine. The rotating machine has a rotatable shaft defining an axis of rotation and a gas flowpath. A system comprises an acoustic panel affixed to an annular casing. The acoustic panel comprises an acoustic treatment member extending between a radially inner skin and radially outer skin. The radially inner skin extends the full axial and circumferential dimensions of the acoustic panel, and the acoustic treatment member overlays the entirety of the radially inner skin. The acoustic panel is positioned so that the radially outer skin abuts the casing, the abutting surfaces being configured to effect relative axial movement between the surfaces while maintaining contact between the surfaces. The acoustic panel is affixed in position to the casing by one or more fasteners passing through the casing and a portion of the radially outer skin.

A sheet for an automobile interior/exterior material provides excellent sound absorption performance. A sheet for an automobile interior/exterior material, which comprises a nonwoven fabric layer in which a fiber weight is 220 g/m.sup.2 to 1,000 g/m.sup.2 and an olefin resin layer laminated on one surface of the nonwoven fabric layer. The formation amount of the olefin resin layer is within a range from 100 g/m.sup.2 to 500 g/m.sup.2, the melt flow rate of the olefin resin is within a range from 1 g/10 minutes to 90 g/10 minutes. The nonwoven fabric layer is impregnated with at least a part of the resin in the olefin resin layer, the olefin resin layer is provided with a plurality of micropores. The sheet for an automobile interior/exterior material as a whole has air permeability of 1 to 60 (cm.sup.3/cm.sup.2.Math.second) in the thickness direction.

A vehicle floor panel is provided in which a honeycomb core made of metal sandwiched and adhered between two CFRP plates is one in which a large number of core units formed into a polygon shape are continuous within one plane so as to share a side of the polygon. Since closed-section parts formed by a hat-shaped cross section part formed along the side and one CFRP plate are continuous with each other at a vertex of the polygon of the adjacent core units, not only is it possible to lighten the weight by opening the interior of the polygon (P) shape core unit, but it is also possible to enhance the energy-absorbing performance by dispersing and transmitting a collision load inputted into one direction of the floor panel toward a plurality of other directions because the high strength load transmission path is continuous with other load transmission paths.

Methods and systems that can produce light weight reinforced thermoplastic articles are described. In some embodiments, a method includes heating and pressing a core layer and then cooling and pressing the core layer to maintain the thickness of the core layer during cooling. Automotive articles, building articles and recreational vehicle articles that can be produced using the methods and systems are also described.

Provided are a non-woven cloth and a layered non-woven cloth that are preferred as a skin material for a composite sound-absorbing material, which has excellent moldability and exceptional shape stability, and with which it is possible to achieve an adequate sound-absorption effect even in thin low-weight regions. The present invention pertains to: a non-woven cloth having a layered structure in which at least one ultrafine fiber layer (M) having an average fiber diameter of 0.3-7 μm and at least one continuous long fiber layer (S) having an average fiber diameter of 10-30 μm are integrated, wherein the non-woven cloth is characterized in that the adhesion area ratio of the ultrafine fiber layer (M) and the continuous long fiber layer (S) is 45-80%; a method for manufacturing the non-woven cloth; a layered non-woven cloth in which two or more layers of the non-woven cloth are layered; and a composite sound-absorbing material in which the non-woven cloth or the layered non-woven cloth, and an open-cell resin foam body or a fiber porous material that is a sound-absorbing material, are layered.

A flooring assembly comprising a flooring unit comprising a stability core layer having a plurality of edge surfaces, two of which have an interlocking mechanism for attachment to the edge surfaces of the stability core of adjacent flooring units; a sound attenuating acoustic layer attached to the bottom surface of the stability core layer; and a finish layer attached to the top surface of said stability core layer.

A sound-absorbing article (e.g., a tufted sound-absorbing article) can comprise a backing having a thickness and a plurality of face fibers associated with the backing. Optionally, the face fibers can comprise a plurality of tufts extending through the backing. The backing can define a plurality of perforations that fully extend through the thickness of the backing and are provided in a pattern to determine an acoustic property of the sound-absorbing article. Within at least a portion of the backing, sequential perforations within the pattern of the plurality of perforations can be spaced center-to-center by between 5 mm and 100 mm.
