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
