Abstract

A manufacturing process is provided that includes arranging a tubular body with a mandrel. The tubular body circumscribes an outer surface of the mandrel and includes a panel and a sheet. The panel includes a porous first skin, a second skin and a cellular core between and connected to the porous first skin and the second skin. The sheet is configured with the second skin to form a pressure vessel. The first skin and the cellular core are located within the pressure vessel. At least a portion of the outer surface comprises an axially convex geometry. The panel is heated. The heated panel is shaped to at least partially conform to the outer surface by pressurizing fluid within the pressure vessel.
