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.

A wheeled trailer sandwich structure comprising:
- outer metallic face sheets;
- a metallic core sheet including alternating peaks and valleys therein, the core sheet adhesively affixed between the outer face sheets to create a wheeled trailer wall or floor sandwich;
- and
- at least one of the outer face sheets comprising multiple parallel elongated grooves which each include a substantially flat bottom wall, a lateral width of which is greater than three times a depth of the bottom wall from a nominal surface of the associated outer face sheet.
A wheeled trailer sandwich structure comprising:
- outer face sheets;
- a core sheet including alternating peaks and valleys therein, the core sheet affixed between the outer face sheets to create a wheeled trailer wall or floor sandwich;
- at least one of the outer face sheets including at least one elongated groove, with an air gap being located between the groove and the core sheet;
- and
- adhesive bonding the face sheets to the core sheet.
A wheeled trailer sandwich structure comprising:
- outer metallic face sheets;
- a metallic core sheet including alternating peaks and valleys therein, the core sheet affixed between the outer face sheets to create a wheeled trailer sandwich;
- and
- a first of the outer face sheets including at least one elongated groove which inwardly projects toward a second of the outer face sheets, the groove including tapered sides spanned by a substantially flat bottom, the bottom having a lateral width at least three times greater than a depth.
