A Simplified Analytical Method for Wound Pressure Vessel Design

Abstract

Composite materials are used to manufacture pressure vessel due to their light weight and higher physical properties. Continuous filament winding process is used to make composite pressure vessels (CPVs) in which fiber is wound over a mandrel. Resultantly, complex interlaced winding pattern especially in the dome section which could significantly affect mechanical behavior and vessel under the internal pressure composite pressure vessel because the layup sequence flips from mosaic to mosaic. This work focuses on analytical approach for finding out the fiber thickness which requires more attention for the optimum design and analysis of CPVs constructed by continuous filament winding process. This new analytical method is obtained by approximating the surface of complete vessel and validated with cubic spline function and Gramoll and Namiki methods [1]. The results have been validated and are quite promising with regards to better accuracy and safety
