A single plenum structural panel comprising a top sheet and a bottom sheet. The top sheet and the bottom sheet being parallel to one another. A plurality of spacing structural elements fixedly attach the top sheet to the bottom sheet, such that a yield strength of an assembled single plenum structural panel is greater than a sum of individual yield strengths of the top sheet and the bottom sheet. A plenum is defined by a spacing between the top sheet and the bottom sheet. The plurality of spacing structural elements are formed such that a first plurality of spaced apart unobstructed pathways are created in the plenum for air to move in a first direction from at least one edge of the single plenum structural panel to at least one of an opposite and an adjacent edge of the single plenum 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.

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 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.

A honeycomb sandwich sheet or panel, based on thermoplastic polypropylene, includes a structure having two flat outer films, thermowelded to a central film that includes a thermoformed blister film, with blisters repeated in a regular and continuous pattern, the flat outer films including a coextruded two-layer film, based on thermoplastic polypropylene, wherein the inner layer faces the central thermoformed film, and the central thermoformed blister film includes a coextruded three-layer film, based on thermoplastic polypropylene, wherein the two outer layers face the flat outer films, and wherein the structure includes and additional layer C thermowelded to the outer layer of the two flat outer films.

A multi-plenum structural panel comprising a top sheet, a middle sheet, and a bottom sheet, each sheet being parallel to the other two. A first plurality of spacing structural elements, fixedly attaching the top sheet to the middle sheet, and a second plurality of spacing structural elements fixedly attaching the middle sheet to the bottom sheet, such that a yield strength of an assembled multi-plenum structural panel is greater than a sum of individual sheet yield strengths. An upper plenum is defined by a first spacing between the top and middle sheets. A lower plenum is defined by a second spacing between the middle and bottom sheets. The first plurality of spacing structural elements is formed such that a first plurality of spaced apart unobstructed pathways are created in the upper plenum for air to move in a first direction from at least one edge of the multi-plenum structural panel to at least one of an opposite and an adjacent edge of the multi-plenum structural panel in each plenum. The second plurality of spacing structural elements is formed such that a second plurality of spaced apart unobstructed pathways are created in the lower plenum for air to move in a second direction from at least one edge of the multi-plenum structural panel to at least one of an opposite and an adjacent edge of the multi-plenum structural panel in each plenum, where the first direction is orthogonal to the second direction.

A laminated board is secured to the inner wall of a cavity wall construction to establish a defined spacing between the inner and outer walls and prevent excess mortar from bridging to the inner wall. The laminated board has a series of spaced sockets into which fasteners may project into the face of the inner wall or framing thereof to secure the outer wall. The board is installed prior to the construction of the outer wall and establishes a minimum spacing or gap between the walls based upon the thickness of the board. The outer wall is constructed immediately adjacent to the outer face of the laminated board. The board is impervious and eliminates bridging by the mortar, eliminates transfer of bulk water from the exterior finish to the inner wall and provides an air conduit to exhaust even the minimal amounts of vapor that will occur in the cavity.
