Abstract
A method for forming a curved acoustic liner panel includes additive manufacturing a honeycomb core that includes a plurality of walls. Each wall of the plurality of walls includes a straight base edge at a flat bottom of the honeycomb core and a corrugated top edge opposite the straight base edge. The honeycomb core is heated and placed between a first curved mold and a second curved mold. The honeycomb core is pressed between the first curved mold and the second curved mold to curve the honeycomb core and stretch the corrugated top edge of each wall of the plurality of walls such that the top edge is no longer corrugated.
