The present application relates to the technical field of composite gas cylinders, in particular, to a metal-lined carbon fiber wound composite gas cylinder and a manufacturing method thereof, comprising a nickel-based alloy lining, a carbon fiber/epoxy resin composite layer and a metal flange, Among them: the nickel-based alloy lining is welded by the gas port joint, the gas port end head, the cylinder, the sealing end head and the sealing end joint; the carbon fiber/epoxy resin composite layer is wound on the outer surface of the nickel-based alloy lining; the metal The flange is connected to the bottom of the sealing end head. The invention has the advantages of simple structure, high reliability, high safety, strong pressure bearing capacity, small body mass, wide medium storage range, strong high and low temperature environment resistance, and can meet the performance requirements of high performance factor and high fatigue life at the same time. The demand for lightweight and high-strength composite gas cylinders in aviation, marine and other fields. |
