Problems solved by technology

Such layer design does not give a theoretical basis, is arbitrary, and cannot maximize the overall strength of the composite gas cylinder structure
In addition, in their invention, there is no mention of the necessary "self-tightening" treatment technology for the aluminum-lined carbon fiber fully wound composite gas cylinder, so that the fatigue life of the composite gas cylinder can only be maintained at a very low level

specific Embodiment approach

[0023] The 6.8-liter aluminum-lined carbon fiber full-winding composite gas cylinder of the present invention uses the aluminum liner as the mandrel, utilizes the fiber winding machine, and completely winds the T700-12KC carbon fiber on the aluminum liner according to the optimally designed laying sequence. structured as figure 1 and figure 2 shown. The specific implementation method is:

[0024] 1) figure 1 and figure 2 In , the structural dimensions of the aluminum lining shown are respectively taken as:

[0025] The length of cylinder 1 is L 1 =414mm, inner diameter D=140mm, sagittal height L of the tail end 2 of the elliptic surface 0 =0.31D, the sagittal height L of the neck 3 of the elliptic surface 2 =0.3D, including the length L of the bottle mouth 4 with M18 internal thread 3 =55mm, wall thickness t=1.8mm, guarantee that the volume of composite gas cylinder of the present invention is 6.8 liters.

[0026] 2) Apply a thin layer of polyurethane varnish on the...

Abstract

The invention is a kind of 6.8L aluminum inner lining carbon fiber total winding compound air collector, which uses the aluminum inner lining made up of elliptical crank tail end, cylinder part, elliptical crank neck part and inner-screwed cock as the core model, the aluminum inner lining surface are winded with carbon fiber layer according to the designed laying order, the outer surface is winded with a glass fiber impact resisting protection layer, and process with 'self tightening' technology in manufacturing process, the aluminum inner lining barrel is winded with fiber layer alternately, spirally and roundly, the elliptically crank tail part and elliptical crank neck carbon fiber layer are variable angle lengthwise fiber layer, there uses ring thick winding on the two ends of the barrel where connecting the elliptical crank tail part and the elliptical crank neck part. The compound air collector satisfies the stress field distribution, it has excellent air tight performance and safety performance.

Description

Technical field: [0001] The invention relates to a 6.8-liter aluminum-lined carbon fiber full-winding composite gas cylinder, which is a high-pressure gas supply equipment for a complete set of portable respiratory rescue devices often used in the fields of fire protection, mining, and chemical industry, and is used to store various types of compressed air under a high pressure of 30MPa. gas. Background technique: [0002] The 6.8-liter aluminum liner carbon fiber full-wound composite gas cylinder is a container for storing compressed air or oxygen. It is a high-pressure gas supply device for various rescue respirators. Compared with steel gas cylinders with the same volume and working pressure The weight is only half of that of similar steel gas cylinders. In the event of an accident, the steel high-pressure gas cylinder ruptures in the mode of sudden fragmentation, while the carbon fiber fully wound composite gas cylinder with aluminum liner has continuous fibers, the rup...
