摘要
A novel structure of woven composite pressure pipes (WCPP) is designed in this paper. Based on the overall geometry structure of woven preform, the representative volume unit (RVU) is established. The effective elastic constants and the mechanical properties of the woven composite layer are predicted by a multi-scale method, and the failure properties are simulated. Compared with filament-wound pressure pipes (FWPP), the WCPP can effectively improve the overall mechanical properties of the composite pressure pipes, and it can promote the further application of composite pressure pipes.
