Abstract
Abstract An outer cylindrical hody composed of a fiber reinforced thermal setting synthetic resin and a cylindrical inner metal body are separately immersed in a bath of cyrogenic liquefied inert gas. The metal body shrinks and is then inserted in the outer body. Upon being removed from the bath and heated, the metal body expands and becomes firmly bonded to the outer body to form the compound body.
