Abstract: A sandwich structure employs a core sheet including alternating peaks and valleys therein, and at least one outer face sheet including grooves or ribs therein. In another aspect, a sandwich structure includes at least one core and at least one adhesively bonded outer face sheet including elongated grooves or ribs formed therein. Yet another aspect of a sandwich structure has raised ridges bridging between adjacent peaks in a core sheet in one direction but not in a perpendicular direction, which synergistically interface, engage or contact with grooves or ribs formed in an outer face sheet.

Abstract: A trailer wall apparatus includes at least one logistics post. In another aspect, a vertically elongated cargo-securing or logistics post is attached adjacent to a vertically elongated depression within a sandwich panel of a cargo container, the sandwich panel employing at least one core sheet including alternating peaks and valleys therein in addition to attached interior and exterior face sheets. A further aspect employs a logistics post including internal lips which contact against and/or assist with alignment to diagonal surfaces of a depression in a container or trailer wall.

Abstract: A container apparatus includes a sandwich structure. In another aspect, a sandwich structure of a container apparatus employs at least one core sheet including alternating peaks and valleys therein in addition to at least one adhesively bonded outer face sheet. Moreover, another aspect of a container apparatus includes a wheeled box trailer, an intermodal shipping container, a railroad car, or other box-like holding and transporting device. An inner container liner, such as a floor, or structural container frame rail is attached to a structural sandwich in another aspect. A joint or connection between adjacent sandwich structures and/or a sandwich structure and an elongated beam, for a container apparatus is also provided.

Abstract: A cargo transportation system includes a sandwich panel and a channel. In another aspect, a cargo-securing or logistics track, or tie-down slat, is attached to a continuously slotted channel which is secured within a sandwich panel of a cargo container, which employs at least one core sheet including alternating peaks and valleys therein in addition to attached interior and exterior face sheets. Yet another aspect of a cargo transportation system includes an interior face sheet flange of a sandwich panel overlapping a flush mounted lateral segment of a slotted channel.

Abstract: A sandwich structure employs a core sheet including alternating peaks and valleys therein. In another aspect, a sandwich structure includes at least one metallic core and at least one adhesively bonded outer face sheet. Yet another aspect of a sandwich structure has raised ridges bridging between adjacent peaks in a core sheet in one direction but not in a perpendicular direction, thereby achieving different properties in the different sheet directions.

Abstract: A sandwich structure is provided that includes a corrugated layer with at least one core layer (structure) made of a periodic array of adjacent truncated upward facing peaks and truncated downward facing valleys. Each truncated peak has a bonding land of an area A1. Each truncated valley has a bonding land of an area A2. A ratio of A1/A2 is less than 2. A distance D is between neighboring peaks, and a distance D is also between neighboring valleys. The corrugated layer is made from an initially flat sheet thickness of t. A first sheet layer is physically coupled to bonding lands of the truncated peaks. A second sheet layer is physically coupled to bonding lands of the truncated valleys.
