Abstract
During a method for forming a structural panel, a core structure is formed that includes a plurality of corrugated ribbons and a plurality of walls. Each of the corrugated ribbons is laterally between a respective adjacent pair of the walls. Each of the corrugated ribbons includes a plurality of baffles and a plurality of porous septums. Each of the porous septums is longitudinally between a respective adjacent pair of the baffles. The forming of the core structure includes bonding a first of the walls to a first of the corrugated ribbons and subsequently bonding a second of the walls to the first of the corrugated ribbons. The core structure is bonded to a first skin. The core structure is bonded to a second skin. The core structure is vertically between the first skin and the second skin, and the first skin is configured with a plurality of perforations.
