    摘要: A process is disclosed for producing a composite hose constructed with a core tube, a reinforcement layer and a cover laminated one on another, the core being made up of a resin inner wall and a rubber outer wall. Gas impermeability and flexibility are enhanced by formation of the inner wall on a mandrel of selected synthetic material and specified bending strength.
