ABSTRACT:
Mold bodies, for example, for the wings of rotary wing aircraft are formed y densifying a core of a hard foam material under such pressure and temperature conditions that later, when the core is placed into a mold together with the cover layer of a heat curable synthetic material, the core will expand again in response to heating the cover layer to its curing temperature. This expansion causes an intimate, complete bond between the core and the cover layer.
