This technology relates materials that are stab, spike and ballistic resistant and to stab, spike and ballistic resistant composite articles incorporating uniaxially oriented, non-woven fabrics. A fabric layer having a non-uniform areal density is formed having thick areas and thin areas, the thick areas having a greater filament/tape concentration compared to the thin areas. In said thick areas, agglomerated tapes/filaments will protrude from the fabric layer surface. Additional layers are then adjoined with the non-uniform layer to form a panel that has stab, spike and ballistic resistance, with protrusions at least partially spacing the additional layers from full, direct contact with the surface of the non-uniform fabric layer to thereby enhance flexibility and stab, spike and ballistic resistance of the whole.

A dimpled substrate for use in an assembly having joined substrates is provided that defines at least one preformed interior cavity, at least one preformed exterior profile adjacent the interior cavity and defining a wall therebetween, and at least one locating feature configured to identify a location of the at least one preformed exterior profile. In one form, the locating feature is disposed in the preformed exterior profile or adjacent to the preformed exterior profile. Alternatively, the locating feature is a notch formed into the dimpled substrate away from the preformed exterior profile.

A chamber for receiving a pressurized fluid may include a tensile member extending between a first chamber barrier layer and a second chamber barrier layer and including a plurality of tethers extending between the first tensile member layer and the second tensile member layer. The chamber may include stitching through the tensile member in a stitched region. When the chamber is pressurized with the pressurized fluid, a substantial majority of the first tensile member layer is separated from the second tensile member layer by a distance that corresponds to a length of the plurality of tethers. In addition, the first tensile member layer is held in contact with the second tensile member layer by the stitching in the stitched region, thereby forming an area of the chamber having a reduced thickness relative to adjacent portions of the chamber.

A joined article includes a first component having a laser-treated surface portion and a second component having a laser-treated surface portion. An adhesive joins the first component to the second component at the treated surface portion. A method of making a joined article form components and a system for making joined articles are also disclosed.

A web of impregnated fibrous material(s) including N individual tapes of fibrous material(s) stacked and/or joined in relation to one another, in which said N tapes adhere to each other and can overlap at least partially. The tapes of fibrous material(s) include continuous fibers impregnated with at least one thermoplastic polymer, and optionally a chain extender. The web has a surface, in cross-section perpendicular to the axis of the fibers, S, that is substantially equal to the sum of the surface, in cross-section perpendicular to the axis of the fibers, of each initial individual tape, denoted S.sub.th, S.sub.th being equal to N×l×Ep, wherein l represents the average width of a tape and Ep represents the average thickness of a tape, N being between 2 and 2000, and the average thickness of each individual tape being less than or equal to 150 μm.

The present disclosure provides a display assembly, including: a display panel which includes: a screen portion, a chip providing portion, a bendable portion located between the screen portion and the chip providing portion, and a spacer portion connected between the bendable portion and the screen portion; a blocking layer on the screen portion; a cured adhesive layer located outside an area of the screen portion and including: a first portion covering the bendable portion and a second portion covering the spacer portion, the first portion and the second portion each having an thickness less than that of the blocking layer, the second portion is in contact with the blocking layer, and a surface of the second portion distal to the spacer portion is substantially flat. The present disclosure also provides a manufacturing method of the display assembly and a display device.

Provided is an interlayer film for laminated glass capable of suppressing double images, and making the moisture resistance of the laminated glass exposed to high temperature and high humidity uniform at one end and the other end of the interlayer film. The interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass, being wedge-like shaped and containing an amphiphile or a surfactant, and when a high temperature and high humidity test for laminated glass is executed, a whitening distance at the one end and the other end of the interlayer film is 15 mm or less, and when a whitening distance at the one end of the interlayer film is more than 0 mm, a value of (whitening distance at the other end of the interlayer film×thickness of the other end of the interlayer film)/(whitening distance at the one end of the interlayer film×thickness of the one end of the interlayer film) is 0.70 or more.

The laminated film for bonding comprises: a first layer; a second layer disposed opposite to the first layer; and a third layer interposed between the first layer and the second layer, wherein the laminated film comprises a first end having a first thickness and a second end having a second thickness different from the first thickness, and a measuring area disposed between the first end and the second end and having a center thickness, wherein the center thickness is less than or equal to a middle value of the first thickness and the second thickness, wherein a penetration coefficient (F.sub.pe) at the measuring area is 1.35 kgf/mm.sup.2*mm or more, and wherein, a ratio of a sum of a thickness of the first layer and a thickness of the second layer to a thickness of the third layer is 100:12 to 24.

An example composite building material includes one or more layers of polymeric fibers, binding agent, and optional fillers, and at least one surface layer of resin-impregnated paper disposed above and/or below the one or more layers. The one or more layers can include a core layer with longer polymeric fibers and top and bottom layers with shorter polymeric fibers. A method of manufacturing the composite building material includes forming the one or more layers, applying the at least one surface layer above and/or below the one or more layers, and heating and pressing the combined layers.

In accordance with at least one aspect of this disclosure, a composite structure can be formed of or including a plurality of composite strips. The plurality of composite strips include one or more filler strips which can have at least one filler edge having a filler edge geometry between a first surface and second surface, the second surface being opposite the first surface. The filler edge geometry can be configured to prevent formation of one or more gaps between one or more adjacent composite strips.
