Numerical Modelling of a High-Pressure Type 2 Cylinder for Storing Natural Gás for Vehicles 2007-01-2936

ISO 11439 standards consider 4 types of high-pressure cylinders to storing natural gas for vehicles applications. Among them the type 2, metal-lined hoop wrapped cylinder, is the aim of this work.
It describes a numerical model built using ANSYS application to determine stress on the metal liner and on composite material applied on the liner by filament winding process. Using design criterion for laminate composites, the total thickness of the composite layer has been evaluated to get an optimized value. Employing the element shell multilayer of ANSYS 8.1 and a model of the type 2 cylinder, the stress state in the metal liner and in each layer of the composite has been studied.
