Abstract

The invention discloses a design method of a high-pressure hydrogen storage tank with a plastic liner. The design method of the high-pressure hydrogen storage tank with the plastic liner comprises structural design and process design; and the structural design comprises material screening and structural design of the plastic liner and design of a carbon fiber winding layer; and the process design comprises the following steps of: (1) planning the process; (2) preparing a test sample; (3) conducting slicing and sampling; and (4) evaluating the volume content of the carbon fiber: performing image acquisition on the longitudinal section cutting plane of the high-pressure hydrogen storage tank through an image acquisition and identification device, identifying a carbon fiber bundle part and a non-carbon fiber bundle part on the longitudinal section cutting plane according to color difference, calculating the proportion of the total area of the section part of the carbon fiber bundle to the area of the whole longitudinal section cutting plane, and taking the proportion as evaluation data of the average value of the volume contents of the carbon fibers in the carbon fiber winding layer; (5) carrying out regional evaluation on the volume content of the carbon fibers; and (6) correcting a process plan. According to the design method of the high-pressure hydrogen storage tank with the plastic liner, design optimization and process optimization of the carbon fiber winding layer of the high-pressure hydrogen storage tank with the plastic liner are realized.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage tank design, in particular to a design method for a high-pressure hydrogen storage tank with a plastic liner. Background technique [0002] The high-pressure hydrogen storage bottle has the advantages of simple structure of hydrogen storage container, less energy consumption for preparation of compressed hydrogen, fast filling speed, etc., and has become the main method of hydrogen energy storage and transportation. At present, there are more high-pressure hydrogen storage tanks with composite liners and carbon fiber fully wound high-pressure hydrogen storage tanks, which use metal (usually aluminum alloy) or plastic as the inner tank, and wrap a layer outside the metal inner tank or plastic inner tank. Carbon fibers impregnated with epoxy resin, cured to form carbon fiber winding layers. The high-pressure hydrogen storage bottle with this structure has the advantages of compressive stre...
