Abstract: The paper analyzes the stress of the composite pressure vessel under internal pressure by ANSYS. The results show that the vessel lining stress will be significantly reduced when applying preloaded forces, and the stress distribution will become more uniform, the utilization of the strength of the carbon fiber is improved, as well the fatigue life of the vessel.

Key words: the composite material pressure vessel, pretension, ANSYS
