Techniques for providing custom formed panels for transport structures including vehicles and aircraft are disclosed. In one aspect of the disclosure, a panel for a transport structure includes a first face sheet, a second face sheet arranged opposite the first face sheet, the second face sheet comprising a different geometrical profile than the first face sheet to define a space between the first and second face sheets having a variable thickness, a core configured to occupy the space. In another aspect, a node can be additively manufactured to form the custom panels by engaging opposing face sheets. The node has an inlet port for providing a foam-like substance into the space between the face sheets to thereafter solidify into a core.

Films, fibers, filaments, yarns and textiles including thermoplastic elastomeric compositions are described, as are methods of making the films, fibers, filaments, yarns and textiles. These films, fibers, filaments, yarns and textiles can be used to make articles of apparel, footwear, and sporting equipment. When thermoformed, the thermoplastic elastomeric compositions can impart abrasion resistance, traction, and other advantageous properties to the articles. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

A panel for machinery enclosure, particularly for turbomachine enclosures. More specifically, a multilayered panel including several different layers each performing a specific function. In particular, the multilayered panel is capable to provide high levels of jet fire and fire/blast protection together with high performances in term of noise abatement with a lighter structure with respect to the panels of the prior art.

Articles, such as garments, including films comprising dried aqueous polyurethane dispersions are disclosed, whereby the garment has an altered stress which is exhibited during wear of the garment. The film may be bonded to the fabric of the article to provide a fabric or film laminate.

A noise attenuating trim part for a vehicle, with acoustic mass-spring characteristics comprising a mass layer comprising at least an impervious barrier layer, and a decoupling layer consisting of open cell foam and wherein the decoupling layer has a first surface adjacent to the mass layer and a second surface facing away from the mass layer, and wherein the decoupling layer and mass layer are laminated together and wherein the decoupling layer has at least one region with a plurality of indentations wherein each indentation comprises a round base area wherein the round base areas are situated in plane with the second surface and wherein the total surface area of the round base areas is between 10 and 40% of the total surface area of the second surface of the decoupling layer.

A method for producing a planar composite component having a core layer (B), which is arranged between and integrally bonded to two cover layers (A, A′), wherein the cover layers contain a cover-layer thermoplastic and wherein the core layer contains a core-layer thermoplastic, comprises the following steps: a) a heated stack with layer sequence A-B-A′ is provided; b) the heated stack (A-B-A′) is pressed; c) the pressed stack is cooled, whereby the planar composite component with consolidated layers integrally bonded to each other is formed. To improve the production method including the producibility of planar 3D components, it is proposed, that at least one of the cover layers (A, A′) in unconsolidated form comprises a fibrous nonwoven layer of 10 to 100 wt.-% thermoplastic fibers of the cover-layer thermo-plastic and 0 to 90 wt.-% of reinforcing fibers having an areal weight of 300 to 3,000 g/m.sup.2; the core layer (B) in unconsolidated form comprises at least one randomly-oriented-fiber nonwoven layer (D) formed from reinforcing fibers and thermoplastic fibers of the core-layer thermoplastic,
and that after the pressing the consolidated core layer(s) has/have an air pore content of <5 vol.-% and the consolidated core layer has an air pore content of 20 to 80 vol-%.

It is an object of the present invention to provide a substrate for lithium ion battery separators which has high adhesion to an inorganic particle layer, can be made thin and is excellent in tensile strength and cuttability and a lithium ion battery separator including the substrate for lithium ion battery separators. The substrate for lithium ion battery separators which contains heat-resistant fibers and synthetic resin short fibers contains fibrillated heat-resistant fibers having a modified freeness of not more than 300 ml as the heat-resistant fibers and has a content of the fibrillated heat-resistant fibers having a modified freeness of not more than 300 ml of not less than 1.0 mass % to less than 5.0 mass % based on the total of all the fiber components contained in the substrate. The modified freeness is a value measured in accordance with JIS P8121-2:2012 except that an 80-mesh wire net having a wire diameter of 0.14 mm and an opening of 0.18 mm is used as a screening plate and the concentration of a sample is 0.1%.

The invention relates to a multi-layered fabric comprising an absorption layer between two liquid-permeable layers, which multi-layered fabric has a surface with: 1) one or more connection areas wherein a connection is present between both layers; and 2) one or more absorption areas wherein both layers are not connected to each other. The absorption areas are capable of absorbing a liquid whereby the liquid is absorbed by the absorption layer. The connection between the layer L1 and the layer L2 comprises a fusion of the layer L1 and the layer L2, which fusion optionally also includes the absorption layer.
