Abstract

The invention provides an ultra-large-size aluminum alloy inner container ultrahigh-pressure full-winding gas cylinder and a manufacturing method thereof. According to the aluminum alloy inner container ultrahigh-pressure full-winding gas cylinder, the aluminum alloy inner container is of an integrated seamless structure with sealing heads and bottle openings formed through closing-in of the two ends, a first sealing head and a second sealing head are located at the two ends of a straight cylinder section respectively, a first bottle opening and a second bottle opening are located on the first sealing head and the second sealing head respectively, the outer side of the aluminum alloy inner container is coated with a 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 curing the carbon fibers through resin, an outer protection layer coats on the outer side of the composite material reinforcing layer, and the outer protection layer is formed by winding glass fibers in a spiral and annular combined winding mode and curing the glass fibers by using the resin. The length of the ultra-large-size aluminum alloy inner container ultrahigh-pressure full-winding gas cylinder is 5-13 m, the nominal outer diameter of the straight cylinder section is phi 300-phi 850 mm, and the use pressure of the high-pressure gas cylinder is 30-90 Mpa.

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 ultra-large 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 ad...
