fiberglass) or carbon fiber-reinforced polymer (CFRP). The older cylinders are GFRP-wrapped, and tensile stress is shared by the GFRP and the aluminum alloy. The newer cylinders are wrapped with a considerably stronger CFRP. On CFRP cylinders, the aluminum alloy serves as an impermeable gas barrier, not a strength member.
