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 the composite 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 lightweight composite 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 0.8mm in thickness are fabricated. A new stronger interface between the composite layer and the ultra thin Al alloy liner is designed according to the structure of the Gecko feet. A Self-healing technology is adopted to improve the reusable properties. With the lightweight composite pressure vessels, the weight can be saved by 70% as compared to the metal pressure vessels with the same volume and the same pressure.
