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.

Claim (Index 1):
A method of making a vehicular trailer sandwich structure, the method comprising:\n (a) applying tension to a metallic core sheet; (b) forming alternating peaks and valleys in the core sheet during step (a); (c) forming raised ridges bridging between at least some of the peaks along a first direction but not along a perpendicular second direction during step (b); (d) the forming steps being done at ambient room temperature with embossing rollers which have rotational axes set at a fixed distance from each other during the forming steps; (e) applying an adhesive to substantially flat ends of the peaks after the forming steps; (f) pre-heating a metallic outer sheet and the core sheet after the application of the adhesive; (g) laminating the vehicular trailer sandwich structure under greater heat than in the pre-heating step, in an oven containing heaters to create at least an initial green curing of the bonded sandwich structure in 30 seconds or less; (h) cooling the laminated vehicular trailer sandwich structure in a cooling unit; (i) wherein out-of-plane shear strength of the core sheet is at least 1.05 times greater in a cross-feeding direction as compared to a manufacturing feed direction; and (j) wherein a length shrinkage factor of the core sheet, where a ratio of initial versus end formed length, is at least 1.08 along the manufacturing feed direction, which is greater than a shrinkage factor along the cross-feeding direction.
