Prefabricated wall assemblies for the construction of buildings have a corrugated panel and preferably include at least one backside panel. The corrugated panel has one or more vertical channels and several horizontal channels. The vertical channels extend the entire panel height and are recessed from the front face. The horizontal channels extending the entire panel width and are also recessed from the front face so they intersect with the vertical channel. The horizontal channels are almost as wide as the vertical channels, and are greater than one-half the vertical channel width. The backside panel is connected to the corrugated panel to form a structural panel assembly. The backside panel can be a shear panel or other backside flat panel, a backside corrugated panel symmetrically mirroring the corrugated panel, a backside corrugated panel asymmetrically mirroring the corrugated panel, a sandwiched corrugated panel, a relief panel or any combination thereof.

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 composite structural panel for use in bridge structures, and method of manufacturing same, comprises a top panel and a bottom panel separated by and attached to at least one, but preferably a plurality, of structural composite preforms which may be fabricated by a continuous manufacturing process and may be saturated by resin using a continuous wetting process. The composite preforms may take any cross-sectional shape but are preferably trapezoidal. The top and bottom panels may be fabricated from a plurality of layers of woven fabric layers and non-woven fabric layers which are saturated with a resin that is subsequently cured using cure processes known in the art. The composite structural panel of the invention is usable as a flat structural member for use as bridge decking, ramps, trestles, and any application requiring a structural panel.

Light-weight, heat-managing structures feature open-cell lattice, honeycomb, and/or corrugated (prismatic) arrangements in their substructures, combined with heat pipe/heat plate arrangements for managing heat to which the structures are subjected. The structures are well suited to aerospace applications and may be employed in the leading edge of wings or other airfoil-shaped components; gas turbine engine components; rocket nozzles; and other high-heat, high-stress environments.

This shaping structure (1) comprises two shaping sheets (5, 7) facing each other at a distance from one another. According to the invention, the shaping structure (1) further comprises a macroporous spacer sheet (9), the spacer sheet (9) being arranged between the two shaping sheets (5, 7) and being corrugated in such a way as to form a series of alternating even peaks (18) and odd peaks (20) distributed in a first direction (D1) of the shaping structure, at least one of the even peaks (18) being attached to the first shaping sheet (5), at least one of the odd peaks (20) being attached to the second shaping sheet (7), each peak (18, 20) attached in this way defining an attachment surface (22, 26) for attachment to the shaping sheet (5, 7) to which this peak (18, 20) is attached.

The present disclosure includes a prefabricated wall panel that is made from materials which are otherwise waste products in the agricultural and forestry industry. Each wall panel includes lateral and longitudinal channels with a step in the sidewalls thereof to accommodate installation of various items. Some of the sidewalls may also include an additional step further recessed into the channel to accommodate other items. Regardless of the number channels and steps therein, the wall panels are also devoid of any shear sharp corner, such that a curved section is provided between each transition to allow for easier manufacturing with composite materials.
