Abstract
The present disclosure provides a pressure vessel 10 (sometimes known as a composite overwrapped pressure vessel or “COPV”) comprising carbon fiber 20 (such as carbon fiber 20 filaments) wrapped around a tank liner 30.
Claims13
A pressure vessel comprising:
- a. an innermost, rigid, gas permeable tank liner consisting of glass fiber reinforced plastic, wherein the tank liner comprises a plurality of central segments and a plurality of cap segments and wherein a first cap segment comprises an integral end fitting;
- b. a middle, flexible, uniform, gas impermeable polymeric permeation barrier applied to the tank liner and wherein the permeation barrier comprises carbon nanotubes;
- and
- c. an outermost carbon fiber overwrap, wherein the carbon fiber overwrap has a variable thickness over different areas of the permeation barrier.

A pressure vessel comprising:
- a. an innermost, rigid gas permeable mandrel substrate consisting essentially of glass fiber reinforced plastic, wherein the gas permeable tank liner comprises a plurality of central segments and a plurality of cap segments and wherein a first cap segment comprises an integral end fitting;
- b. an outermost discrete carbon fiber overwrap, wherein the carbon fiber overwrap has a variable thickness over different areas of the tank liner;
- and
- c. a middle gas impermeable polymeric permeation barrier, wherein said barrier is located between the gas permeable mandrel substrate and the carbon fiber overwrap.
1 more element
A pressure vessel comprising:
- a. an innermost, rigid gas permeable mandrel substrate comprising a plurality of segments bonded together, said segments comprising a body, a first dome cap, and a second dome cap, wherein the mandrel substrate is uniform in composition and comprises a non-polymeric material, wherein the gas permeable tank liner comprises a plurality of central segments and a plurality of cap segments and wherein a first cap segment comprises an integral end fitting;
- b. a middle, non-loadbearing, uniform, flexible, gas impermeable polymeric permeation barrier covering the gas permeable mandrel substrate;
- and
- c. an outermost fiber overwrap covering the gas impermeable permeation barrier.
