Problems solved by technology

Due to the phenomenon of oblique stretching and repeated overlapping of fibers in this kind of fiber winding reinforced structure, it not only wastes fibers and increases its own weight, but also fails to fully utilize the potential of high tensile strength of fibers, so the bottle body is resistant to pressure. poor performance

Embodiment Construction

[0011] The structure and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0012] As shown in Figures 1 and 2, it has a cylindrical bottle inner lining, and the outer surface of the inner lining of the bottle is wound with reinforcing fibers, and the reinforcing fibers are axially wound along the outer surface of the inner lining of the bottle 1 to form an axial layer 4. The reinforcing fibers are also wound along the circumferential direction of the outer surface of the cylindrical bottle inner lining 1 to form a circumferential layer 3, and the directions in which the reinforcing fibers of the two layers are wound are orthogonal; The head is provided with two upper and lower buckle caps 2 and 5 made of high-strength steel material, and the inner concave surface of the upper and lower buckle caps 2 and 5 is closely connected with the convex outer surface of the bottle inner liner 1 hemispherica...

Abstract

The orthogonal wound composite high-pressure gas cylinder has inner lining and reinforcing fiber wound to the outer surface of the lining. The reinforcing fiber is first wound axially to constitute axial reinforcing layer and then circumferential to constitute circumferential reinforcing layer with the two reinforcing layers being orthogonal. Onto the two semi-spherical end covers of the lining, there are upper and lower outer covers contacting with the end covers closely and the outer covers have notches with hooks for the reinforcing fiber to be wound axially. The cylinder is light and highpressure resistant.

Description

technical field [0001] The invention relates to a high-pressure gas cylinder, in particular to an orthogonally wound composite high-pressure gas cylinder. Background technique [0002] In the prior art, high-pressure gas cylinders are filled with gas or gas-liquid mixture, and have a large internal pressure. The internal pressure on the gas cylinder can be decomposed into two parts: one is distributed along the circumferential direction and is perpendicular to the inner wall of the cylinder, and the other is distributed along the axial direction and exerts pressure on the inner surface of the two ends of the cylinder. Generally, gas cylinders are made of steel, which is strong but heavy, and some are made of aluminum alloy, which is not strong enough. So people are looking for composite gas cylinders with lightweight materials and high pressure resistance. Commonly used composite gas cylinders adopt the oblique overlapping winding of reinforcing fibers along the outer wall...
