摘要
A novel structure of braided composite pressure vessel (BCPV) is designed in this paper. Based on the overall geometry structure of braided preform, the representative volume unit (RVU) model is established. The effective elastic constants and the mechanical properties of the composite layer of BCPV are predicted, and compared with filament-wound pressure vessel (FWPV). Numerical results show that BCPV can effectively improve the overall mechanical properties of the composite pressure vessel, and has a wide application prospect.
