Abstract: A generally planar metal honeycomb panel is formed into a complex compound curved shape by initially forming a primary first curvature in the panel using a conventional stretch wrap process. Following the primary stretch wrap process, a second stage form block having a curved portion conforming to the primary curvature and reverse curved shoulder portions is positioned against the primary curved portion of the honeycomb panel. Thereafter, a reverse wrap process is applied to the honeycomb panel to form an undulating wave form panel. The undulating wave form panel is then subjected to a secondary stretch wrap process upon a secondary stretch form block having the undulating curvature of the undulating wave form plate in one direction and a further curvature in the transverse direction thereto. In an alternate method, primary first curves and secondary stretch wrap are used to form panels which are joined by welding or other attachment to form more severely reverse-curved panels.
