Abstract
A system is disclosed for the manufacture and use of a composite reinforced gas transport module ('GTM'). A metal shell of the system is wrapped circumferentially with a composite reinforcement, the composite reinforcement is post cured and the metal shell is then pressurized beyond the yield point of its material to load the composite reinforcement. The system is then brought to ambient temperature. The expansion deformation of the metal shell due to pressurization beyond the yield point results in a loading of the metal shell by the cured composite reinforcement at ambient temperature. Thus, a negative hoop stress condition is created in the metal shell at ambient to reduce the hoop stresses created during subsequent pressured operation.
