Abstract
Abstract A container or conduit for compressed gas and/or cryogenic gas is constructed with a gas impermeable synthetic polymer forming a gas barrier 14 and a structural component 16 that provides structural integrity to the container or conduit. The structural component is associated with the barrier 32. The gas impermeable synthetic polymer is preferably a thermotropic liquid crystal polymer.
