HOLLOW PRESSURE RESISTANT BODY AND A METHOD FOR MANUFACTURING THE SAME

摘要

A container, especially a flat container suitable for confining high internal pressures includes inner membranes secured to lateral side frame members. The inner membranes have inwardly facing convex surfaces and bear against outer walls through hard foam filler material located in the spaces between the inner membranes and the outer walls. The membranes and the walls are manufactured by filament winding techniques.
