A method of manufacturing cross-corrugated support structures is provided. A mold having a molding surface with a first plurality and a second plurality of corrugations therein is used to introduce corrugations into a flexible, carbonaceous sheet. Cross-corrugations are introduced into the sheet by placing the sheet onto the molding surface, encapsulating the sheet to form a vacuum chamber, and evacuating the vacuum chamber of air. As air is evacuated from the vacuum chamber, the sheet is drawn upon the molding surface causing the sheet to conform to the shape of the molding surface. Thermosetting resin is infused into the sheet and cured causing the sheet to rigidly retain the shape of the molding surface. The sheet is further reinforced by securing at least one support member to the sheet using thermosetting resin.

A cross-corrugated support structure includes a sheet having a first and a second set of corrugations. The first set of corrugations is defined by a series of alternating ridges and grooves that extend the length of the sheet in a first direction. The second set of corrugations is also defined by a series of ridges and grooves that extend the length of the sheet in a second direction that intersects with the first direction. The intersection of the first and second set of corrugations creates cross-corrugations throughout the sheet. To provide compressive and tensile strengths suitable for large-scale construction applications, the sheet may be made of a carbonaceous material such as carbon fiber or graphite treated to rigidly retain a shape including the first and second set of corrugations within the sheet. The sheet may be reinforced by securing support members or additional corrugated sheets to the sheet.
