The first apertured protuberances are located in the first lanes. A plurality of second lanes are aligned in the first direction and have a second width, less than the first width, extending in the second direction. The first lanes and the second lanes alternate with each other in the second direction. The second apertured protuberances are located in the second lanes.

A core layer suitable for a multilayer composite including at least one surface layer and one core layer, the surface layer arranged to at least partially cover the core layer and be fixedly connected thereto, wherein the core layer has elements composed of wood, which elements have plate-like regions arranged in zig-zag-shaped fashion, wherein a plate-like zig region of an element with an adjoining plate-like zag region of the element form a common edge between them, in such a way that the wood element of zig-zag-shaped form is formed, wherein elements of zig-zag-shaped form are arranged in the core layer such that two such edges of two different elements cross one another at a non-zero angle, and wherein the two elements are fixedly connected to one another at the crossing point. In one embodiment, a wood element of zig-zag-shaped form may be adhesively bonded to a planar wood element.

A film for a composite article may include a non-weakened portion and a weakened portion. The weakened portion may have at least one property that may be lower than the property of the non-weakened portion.

An incrementally activated laminate that includes an incrementally activated fibrous web and a film having alternating first and second regions and a laminate of the film and an extensible fibrous web. The first region of the film includes a first polymeric composition, and the second regions include an elastic polymeric composition that is more elastic than the first polymeric composition. In the incrementally activated laminate, the distance between midpoints of two first regions separated by one second region is smaller than the activation pitch, and the first regions are not plastically deformed. In the extensible laminate, a tensile elongation at maximum load of the film is up to 250 percent of the tensile elongation at maximum load of the extensible fibrous web. Methods of making the laminates are also described.

A composite material and structure. The structure has a folded sheet having a rigid inner layer sandwiched between flexible outer layers. The sheet has an undulated shape with alternating summit and valley portions. Intermediate portions each extend between adjacent summit and valley portions. At least one score line extends through at least one of the flexible outer layers. The sheet is folded about the at least one score line. A method of forming a structure from a sheet having an undulated shape

A containerboard packaging material includes at least one linerboard layer including tree-based pulp material and at least one fluted medium layer including tree-free pulp material, wherein the tree-free pulp material is present in the medium layer in an amount of from about 5% to about 100%. The medium layer pulp material can be tree-free pulp material. The tree-free pulp material can be wheat straw pulp and red algae pulp.

A composite structure (10) includes a first outer skin (12); a second outer skin (14); and a core (16) sandwiched between the first outer skin (12) and the second outer skin (14). The core (16) includes a plurality of spaced apart ridges (18) between the first outer skin (12) and the second outer skin (14), each of the spaced apart ridges (18) extending from one end (20) of the composite structure (10) to an opposite end (22); and a plurality of connecting elements (24) between the first outer skin (12) and the second outer skin (14) configured to intersect with the ridges (18) to form open channels (26) within the core (16). At least one of the first outer skin (12), the second outer skin (14) and the core (16) includes: a plurality of composite plies including at least a first composite ply and a second composite ply, the first composite ply and the second composite ply each including a plurality of fibers in a thermoplastic matrix; the plurality of composite plies being bonded together to form a composite laminate.

A corrugated sheet metal wall sheathing for resisting external excitations such as wind or earthquake of light-framed wall structures. The sheathing has sheet profile proportioned to insure the top flutes deform laterally and yield at the end of the flute before the onset of any failure mode. A transverse slot in included ineach top flute and adjacent web of the sheathing and spaced at intervals along the length of the sheathing.

The present invention relates, in general, to a novel artwork surface and, in particular, to an ultra lightweight dispersed solid artwork surface and methods of creating artwork structures. Techniques are described herein that are capable of creating an innovative artwork structure. For example, a method of preparing a dispersed solid artwork surface, applying said medium to said dispersed solid artwork surface, finishing said dispersed artwork surface to create an artwork structure, and displaying said artwork structure.

Protection barriers, such as floor protection barriers, and methods for making and using same. The protection barrier can include a base sheet and an energy absorbing layer. The base sheet can have two or more paperboard layers and one or more sizing layers. A first paperboard layer can form a first surface of the base sheet, a second paperboard layer can form a second surface of the base sheet, and the one or more sizing layers can be disposed between the first and second paperboard layers. The energy absorbing layer can be secured to the second paperboard layer.
