Concentric Shells for Compressed Gas Storage

摘要

Gas containment vessels are provided that are comprised of an inner corrosion resistant shell made of lower strength steel alloy or aluminum alloy or thermoplastic polymer, and an outer concentric shell constructed of high strength, albeit lower corrosion resistant, metal or fiber-reinforced composite. The fiber can comprise filaments derived from basaltic rocks, the filaments having been immersed in a thermosetting or thermoplastic polymer matrix, and comingled with carbon, glass or aramid fibers such that there is load sharing between the basaltic fibers and carbon, glass or aramid fibers.

主权项

1. A high pressure gas storage vessel, comprising:
an inner shell made of corrosion-resistant, low strength alloy steel or aluminum alloy having approximately 700 MPa tensile strength; and a concentric outer shell made of high-strength steel of tensile strength up to 1,800 MPa in a load-sharing fashion, such that the overall weight is lower than that of a vessel made of lower strength alloy steel alone.
