A method of fabricating a low total density, stabilized ramped honeycomb core for high pressure co-cure molding of a lightweight honeycomb core composite article includes forming the honeycomb core by net shaping stabilized honeycomb core material into a ramped honeycomb core. The ramped honeycomb core is prepared for lay-up and co-cure by applying a layer of low areal weight film adhesive to the upper and lower surfaces and to each ramped surface of the ramped honeycomb core. The honeycomb core material is stabilized for the net shaping operation by applying a layer of low areal weight film adhesive to the upper and lower surfaces of the honeycomb core material in a predetermined picture frame format.
