Abstract
The invention provides an aluminum alloy inner container ultrahigh-pressure full-wrapped gas cylinder and a manufacturing method thereof. The aluminum alloy inner container ultrahigh-pressure full-wrapped gas cylinder comprises an aluminum alloy inner container, a composite material reinforcing layer and an external protective layer; the aluminum alloy inner container is of an integrated seamless structure with the two ends closed to form closure heads and cylinder openings, the first closure head and the second closure head are located at the two ends of a straight cylinder section respectively, and the first cylinder opening and the second cylinder opening are located on the first closure head and the second closure head respectively; the length of the gas cylinder is not greater than 5 m, the nominal outer diameter is (406, 850) mm, and the working pressure is (30, 90) MPa; the outer side of the aluminum alloy inner container is coated with the composite material reinforcing layer, and the composite material reinforcing layer is formed by winding carbon fibers in a spiral and annular combined winding mode and then performing curing by using resin; and the outer side of the composite material reinforcing layer is coated with the external protective layer, and the external protective layer is formed by winding glass fibers in a spiral and annular combined winding mode and then performing curing by using resin.
Description
technical field [0001] The present application relates to the technical field of high-pressure containers, in particular to an ultra-high-pressure full-wound gas cylinder with an aluminum alloy liner and a manufacturing method thereof. Background technique [0002] With the rapid development and industrialization of hydrogen fuel cells and electric vehicles, the research and construction of hydrogen source technology and hydrogen energy infrastructure have attracted great attention from developed countries. Safe and economical hydrogen storage and transportation technology is the key to promote the practical and industrialization of hydrogen energy utilization. High-pressure hydrogen storage using ultra-high pressure cylinders with a pressure of 35-90MPa is the most common and direct way of hydrogen storage. High-pressure hydrogen storage can be used at room temperature, and the hydrogen can be released directly through the adjustment of the valve. It has the advantages of ...
