ABSTRACT:
A method and a mold for fabricating an aerodynamic airframe structure or the like. The method using foam material introduced into the mold having split halves. The mold constructed for receiving a prefabricated stiffener skin. The mold acts as a backup restraint for the airframe structure or any other part being produced. The foam injected into the cavity adheres to the stiffener skin thereby forming an elastic foundation of continuous support for the stiffening element.
