Hydrogen storage cylinder and preparation method thereof

The invention provides a hydrogen storage cylinder and a preparation method thereof, and belongs to the technical field of gas storage. The preparation method of the hydrogen storage cylinder comprises the following steps: winding carbon fibers on the lining by adopting a wet winding process to form the carbon fiber layer, winding polyimide fibers on the surface of the carbon fiber layer to form the polyimide fiber layer, and winding basalt fibers on the surface of the polyimide fiber layer to form the basalt fiber layer. The dipping slurry of the carbon fibers, the polyimide fibers and the basalt fibers is polyimide resin. The carbon fiber layer, the polyimide fiber layer and the basalt fiber layer are formed from inside to outside, polyimide resin is selected as winding layer curing resin, and a geodesic wire winding process and a non-geodesic wire winding process are comprehensively adopted; the minimum bursting pressure, the filling fatigue frequency, the weather resistance, the air tightness, the service
