Abstract: In this paper we apply semi-geodesic trajectories to the creation of isotensoid
domes for filament wound pressure vessels. The governing equations for the determination of
the meridian shapes and related winding angle distributions of domes are derived using the
netting analysis and the semi-geodesic winding law. The effects of the slippage coefficient on the
geometry and fiber trajectories of the domes are respectively evaluated in terms of the resulting
meridional curves and fiber angles. It is revealed that the semi-geodesic angles and the dome
depth have an overall decrease with increasing the slippage coefficient. The results also
demonstrate that the use of semi-geodesics significantly enlarge the design space for the
geometry and adapted fiber trajectories of the domes. The present method can provide a
significant reference for the design and production of the domes for semi-geodesically
overwound pressure vessels. © (2013) Trans Tech Publications, Switzerland.
