Disclosed are an undercover for vehicles with high elasticity and rigidity and a method of manufacturing the same. The undercover for vehicles with high elasticity and rigidity may include a needle-punched nonwoven fabric having a multi-layer structure of felt layers including a first PET fiber and a low-melting-point PET fiber, and each of the felt layers may have improved tensile strength and have optimized fiber alignment, to thereby improve the binding between fibers, mechanical rigidity and elasticity, as well as to reduce the weight of components, improve durability and secure harmlessness and inline workability.

A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer of fibers and adhesive providing dimensional stability for the entire floor covering. The fibers and adhesive are mixed and then moved by an applicator towards the stitches. A slip path is formed to improve the movement of the fibers and adhesive. A releasable adhesive or gecko-like cover system is provided which also provides additional strength and stability and a releasable attachment of the universal floor covering to a supporting surface.

A photovoltaic apparatus (200) is provided including a back sheet (210) and a photovoltaic device (100) disposed over the back sheet. The photovoltaic device includes an array of photovoltaic cells (101-104) extending in a first direction; and a plurality of serial interconnects (191) 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 (250) disposed over the photovoltaic device, the front sheet having a plurality of structures (220), wherein each structure has one or more edges (221) aligned with one of the serial interconnects.

The present invention relates to a fastening structure of a composite material structure, and more particularly, to a composite material stitching structure reinforced with z-direction fiber which improves strength in a lamination direction of a relatively weak composite material structure, for a composite material structure, in which composite materials are laminated and bonded.

A dimensionally stable universal floor covering includes a tufted textile having stitches and a reinforcement layer operatively connected to the stitches to provide dimensional stability for the entire floor covering. The reinforcement layer is made of fibers and adhesive that are formed into a reinforcement layer of laminated fibers that is operatively connected to the stitches and/or the fibers and adhesive are formed into a layer of fibers and adhesive that is contained within the stitches. The fibers and adhesive are mixed and then moved by an applicator toward the stitches. A curved slip path is formed on a curved portion of the applicator to improve the movement of the fibers and adhesive toward the stitches. A removable tip portion on the end of the curved portion of the applicator improves the penetration of the adhesive and provides compression of the fibers towards the ends of the stitches. A releasable adhesive cover system is provided to cover the layer of fibers for providing additional strength and stability and for providing a releasable attachment of the universal floor covering to a supporting surface.

The present invention relates to impact resistant flexible material, comprising a bilayered fabric comprising two adjacent unidirectional monolayers each comprising polymer fibers, with the direction of each unidirectional monolayer being rotated at an angle with respect to the direction in the other unidirectional monolayer; and at least one unidirectional spacer comprising polymer fibers, said spacer is attached to an external surface of one of said unidirectional monolayers and is covering a portion thereof.

The invention relates to a method for producing a component from a fibre composite material by deforming a thermoplastic organic sheet (2) in a membrane press (1), wherein a mould (4) is arranged in the membrane press (1), wherein at least one organic sheet (2) is positioned on or in the mould as a work piece, and wherein an elastically flexible membrane (11) is flexibly stretched over the mould (4) with the interposition of the organic sheet (2). In this way, the organic sheet (2) is deformed with the formation of the component, wherein the membrane (11) is applied with an under-pressure on the side facing the mould, and with an over-pressure on the side facing away from the mould, such that the organic sheet (2) is shaped onto the mould.

A containment material for a containment system to provide protection against the diffusion of contaminants in a containment area. A structured felt geotextile surface layer is joined with a geomembrane barrier layer to form a lamination. The geomembrane barrier layer is substantially impervious to liquid diffusion. The structured felt geotextile surface layer comprises a needle-punched, non-woven felt with an upper surface structured to have a surface pattern of peaks and valleys. A containment system is formed from a plurality of strips of containment material joined by liquid-impervious bonds to provide coverage to the containment area. A process for forming a containment material comprises providing a structured felt geotextile layer formed with first and second needling operations to produce a surface pattern and a liquid impervious geomembrane barrier layer and joining the layers to form a lamination.
