AI Technical Summary
Existing carbon fiber hydrogen storage tanks exhibit significant volume changes under high pressure, leading to localized thinning of the inner liner, decreased sealing performance, and reduced overall deformation capacity, increasing the risk of hydrogen leakage. Furthermore, the large amount of carbon fiber required results in high costs.
The structure adopts an inside-out design, including an inner liner, a pressure-resistant layer, a ceramic layer, and an outer protective layer. The ceramic layer is 20mm to 50mm thick and has a tensile strength of ≥180MPa. The pressure-resistant layer is made of carbon fiber. The first resin is filled between the ceramic layer and the pressure-resistant layer. The outer protective layer is made of a rigid material. The second resin is vinyl resin, which is filled between the ceramic layer and the outer protective layer. The resin is cured at room temperature.
The thickness of the pressure-resistant layer and the amount of carbon fiber used were reduced, which lowered the difficulty of degassing and manufacturing costs, improved the thermal insulation performance and overall reliability of the hydrogen storage material, reduced the risk of hydrogen leakage, and extended its service life.
