Abstract：This paper mainly based onthe Lamécalculation formula for isotropic thick-walled pressure vesels and the mesh strength theoryforanisotropiccomposite material thin-walld pressure vesels，proposesathicknesscalculationformula for type 1 high-pressure hydrogen storage cylinders， n amelykι′=3Pb/⌊4σh-（6～8）∗Pb⌋） ，whichisusedforthe early performance parameter evaluation of the product andthe lateroptimizationofthe fiber winding layup structure.The thicknesscalculation formulafor thick-waled pressure vessels iscompletedonthebasisofthebalanced strength thickness kt= 3Pb/4σfb of the cylinder body （withoutconsidering the reinforcementcoeffcient of the head），and the modificationof the thick-walledwindinglayerthicknessiscompletedbasedon twoparts：theincreaseincross-sectionalareaandtheincrease incircumferential stress.
