Abstract
A container or conduit for compressed gas and/or cryogenic gas is constructed with a gas impermeable synthetic polymer forming a gas barrier and a structural component that provides structural integrity to the container or conduit. The structural component is associated with the barrier. The gas impermeable synthetic polymer is preferably a thermotropic liquid crystal polymer.
Claims13
A container or conduit for compressed gas and/or cryogenic gas comprising:
- gas barrier means for containing the compressed gas and/or cryogenic gas, said gas barrier means comprising a gas impermeable synthetic polymer, said polymer being selected from the group consisting of liquid crystal polymers, polyacrylonitrile, polyether ketone, polyether ether ketone, polyether ether ketone ketone, high density polyethylene, and ultra high molecular weight polyethylene;
- and
- means for providing structural integrity to the container or conduit, said structural means overwrapping said gas barrier means.
A container or conduit for compressed gas and/or cryogenic gas comprising:
- gas barrier means for containing the compressed gas and/or cryogenic gas, said gas barrier means comprising a gas impermeable synthetic polymer, said polymer having a permeability coefficient less than or equal to 1.8.times.10.sup.-11 cm.sup.3 (STP).multidot.cm/cm.sup.2 .multidot.sec.multidot.cmHg;
- and
- means for providing structural integrity to the container or conduit, said structural means overlapping said gas barrier means.
A container or conduit for compressed gas and/or cryogenic gas comprising:
- a wall of the container or conduit includes a resinous matrix with structural fibers embedded within said resinous matrix, said resinous matrix comprising a gas impermeable synthetic polymer, said polymer being a means for containing the compressed gas and/or cryogenic gas and being selected from the group consisting of liquid crystal polymers, polyacrylonitrile, polyether ketone, polyether ether ketone, polyether ether ketone ketone, high density polyethylene, and ultra high molecular weight polyethylene, and said structural fibers being means for providing structural integrity to the container or conduit.
A container or conduit for compressed gas and/or cryogenic gas comprising:
- a wall of the container or conduit includes a resinous matrix with structural fibers embedded within said resinous matrix, said resinous matrix comprising a gas impermeable synthetic polymer, said polymer being a means for containing the compressed gas and/or cryogenic gas and having a permeability coefficient less than or about 1.8.times.10.sup.-11 cm.sup.3 (STP).multidot.cm/cm.sup.2 .multidot.sec.multidot.cmHg, and said structural fibers being means for providing structural integrity to the container or conduit.
