Method of manufacturing cross-corrugated support structures
11618225 · 2023-04-04 · ·

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.
