Cross-corrugated support structure

A cross-corrugated support structure comprising:

• a carbonaceous rigid sheet having a first plurality of corrugations and a second plurality of corrugations,
• the first plurality of corrugations being defined by a series of alternating primary ridges and primary grooves extending a length of the sheet in a first direction,
• wherein each primary ridge and primary groove has a face extending therebetween,
• the second plurality of corrugations being defined by a series of secondary ridges and secondary grooves extending a length of the sheet in a second direction perpendicular to and intersecting with the first direction such that each corrugation within the second plurality of corrugations intersects the face extending between each primary ridge and primary groove such that each face is divided into a plurality of sub-faces, wherein each secondary ridge and secondary groove is disposed on a surface of the face extending between each primary ridge and primary groove;
• and
• a plurality of elongated support members secured to the sheet such that each support member of the plurality of support members bridges at least one of each of the primary ridges and each of the primary grooves.

• a second rigid sheet secured to the first sheet, the second sheet having a third plurality of corrugations and a fourth plurality of corrugations,
• the third plurality of corrugations being defined by a series of alternating primary ridges and primary grooves extending a length of the second sheet in a first direction,
• wherein each primary ridge and primary groove of the second sheet has a face extending therebetween,
• the fourth plurality of corrugations being defined by a series of secondary ridges and secondary grooves extending the length of the second sheet in a second direction intersecting with the first direction such that each corrugation within the second plurality of corrugations intersects the face extending between each primary ridge and primary groove of the second sheet
• wherein the second sheet is secured to the first sheet such that the first plurality of corrugations is out of phase with the third plurality of corrugations and the second plurality of corrugations is out of phase with the fourth plurality of corrugations.
