Influence of stacking sequence

Abstract

The established framework of in situ characterization methodology and FE modeling approach permits to investigate structural aspects with regard to the design of composite pressure vessels in-depth. In this chapter the influence of the CPV stacking sequence is studied thoroughly on the subscale geometry by taking into account its effect on the laminate consolidation level, deformation behavior, damage propagation and final failure. This is exercised by changing the sequence and grouping of layers for a known layup, while remaining its initial composition of plies. The purpose of this is twofold. On the one hand, further insights about the mechanical response of CPVs are derived by considering a variety of stacking sequences. On the other hand, the established methods can further be scrutinized regarding their validity through the application to various stacking sequences.
