Abstract

A numerical analysis of a composite internally pressurized cylindrical vessel with spherical domes is presented. The structure is considered a filament winding process vessel in which a continuous strand of fiber is wound over a rotating male mandrel. During the winding process a variable thickness is created in the dome region which considerably alters its mechanical performance. Additionally, the fiber path depends on the surface where the fibers are wound; as a result the winding angle varies in the dome with regards to its longitudinal direction. The vessel is modeled as a non-structural internal liner reinforced with an orthotropic composite: carbon fiber reinforced plastic. Stress was calculated b
