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.

Reinforced boards and/or walls, and methods of producing thereof. In some non-limiting examples, there is provided a reinforced gypsum board and a process for the production thereof. In one example, the reinforced board may include one or more reinforcing elements, e.g., to enhance the rigidity of the board and/or to provide support for the board.

A multi-functional composite structure has a modular design that can be altered depending on an extreme environment in which the structure will be exposed such as hazardous radiation, micro-meteoroid and orbital debris impacts, extreme temperature changes, etc. The material combinations employed in the multi-functional composite structure provide a supporting structure with low weight and maximum protection from radiation, debris impacts and temperature variations.

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 panel structure includes panel members that may be connected together using friction stir welding, Each of the panel members includes a first plate, a second plate substantially in parallel to said first plate, and at least one webbing member connecting the first plate and the second plate. The first plate of the first panel member includes a flange positioned in abutment with a flange located on the first plate of the second panel member. The flange of the first panel member includes a projection and the flange of the second panel member includes a groove. The panel members are connected so that the projection is engaged with the groove to thereby resist relative lateral movement that would separate the panel members.

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.

Construction components and systems fabricated using extruded materials are disclosed. A particular embodiment includes: a sheet fabricated from an extruded material; and a core structure internal to the sheet, the core structure including voids, the voids being triangular-shaped and arranged in an alternately inverted pattern.

A panel includes a base layer configured to have plural first protuberances; a core layer disposed on the base layer and configured to have plural second protuberances, wherein one or more of the plural second protuberances have first slots in a top portion; inserts provided on the base layer and inside the one or more of the plural second protuberances of the core layer; and a top layer in direct contact with the plural first protuberances and the plural second protuberances and configured to have second slots that correspond to the first slots. The inserts are exposed to ambient through the first slots and the second slots.

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 channel width of the vertical channel. 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, or any combination thereof.

Method of making a wavy wood element (B) from a wood element (A), wherein the method comprises at least steps (H1) to (H4): (H1) providing a wood element (A), which comprises fibers and lignin on or between said fibers; (H2) heating the wood element (A) to a temperature which is sufficient to soften or melt at least a part of the lignin; (H3) deforming the wood element heated in step (H2) such that a wavy wood element (B) is formed; (H4) cooling the wood element deformed in step (H3); characterized in that the deforming in step (H3) is performed such that the ratio of the wave height to the thickness of the wavy wood element (B) equals or is more than 2:1; wherein the term thickness signifies the shortest distance between an upper side and the respective lower side of the wavy wood element (B), and the term wave height signifies the shortest distance between two imaginary planes which run in parallel to one another between which the wavy wood element (B) may be arranged such that the waves are positioned between said planes; and wherein the wood element (A) consists of unglued wood or unglued wood fibers.
