Evaluation of the Mechanical Performance of a Multi-Cell Composite Overwrapped Pressure Vessel for Cryogenic Storage
Abstract
This study focuses on establishing an operating window of a multi-cell structure for storing cryogenic propellants, with the use of an FE-based progressive failure analysis. The multi-cell is a Type IV structure (composite over-wrapped with a polymeric liner) that was modelled with temperature dependent properties, obtained by coupon testing and fitting functions. A optimized composite patch shape and number of reinforcing rings are identified based on minimization inplane shear during draping and spheres-intersections strain compatibility respectively.
