Abstract
A method is provided for forming a structured panel. During this method, a cellular core is formed that comprises a corrugated ribbon configured with a plurality of baffles and a plurality of septums. Each of the septums extends longitudinally between and connected to a respective adjacent pair of the baffles. At least one element of the corrugated ribbon includes a structural reinforcement. The forming includes: feeding a ribbon of material between a first roller and a second roller, corrugating the ribbon of material with the first roller and the second roller to provide the baffles and the septums, and stamping the structural reinforcement into the element with the first roller and the second roller. The cellular core is bonded to a first skin. The cellular core is bonded to a second skin. The cellular core is vertically between the first skin and the second skin, and the first skin is configured with a plurality of perforations.
