Abstract In the development of the new energy cars, the rocket engine systems and the satellites, there are some special requirements,
such as the high air tightness, the lightweight and the long-life, for posite pressure vessels used to store the liquid propellant and
high pressure gas. In this paper, a new method is proposed to design and prepare the posite pressure vessels with ultra
thin metal liner. A characterization method for the slippage coefficient measurement between the fiber and the mandrel is developed. The
Al alloy liners of in thickness are fabricated. A new stronger interface between pos
