Ultra-light, weather-resistant and high-strength stratosphere skin material

Abstract

The invention provides an ultra-light, weather-resistant and high-strength stratosphere skin material which has high strength and weatherability, relating to skin materials. The ultra-light stratosphere skin material consists of a weather-resistant layer, a force bearing layer, a block layer and a heat sealing layer from outside to inside. Vectran fiber 200 Daniel plain woven fabric with ultra-high strength is selected and used as the force bearing layer, the Vectran fiber 200 Daniel plain woven fabric has the strength about 6 times as high as that of common polyesters, and the light weight of 54 g/m<2> and the thickness of 0.16 mm. The produced stratosphere skin material has ultra-light mass.

Description

technical field [0001] The invention relates to a skin material. Background technique [0002] Stratospheric airship is a new type of air platform, which has great application value in missile defense, anti-terrorism, communication, remote sensing, space observation and atmospheric measurement. In recent years, the international community has attached great importance to the development of stratospheric airships, and the skin material has become a major technical key in this development process. The air in the stratosphere area is thin, which is about 1 / 14 of the surface air density. If the surface density of the material is too high, the net buoyancy of the airship will be greatly lost, and it will be difficult to rise to the height of the stratosphere. Therefore, the quality of the stratosphere skin material is required to be light. . In addition, the concentration of ozone in the stratosphere environment is very high, and the ultraviolet radiation is strong. Ozone has a...

Problems solved by technology

At the same time, the skin material has to withstand a large internal and external pressure difference, and it must also withstand the influence of strong winds formed by the low-altitude atmosphere, which greatly increases the strength requirements for the skin material. Moreover, modern large-scale stratospheric airships are bulky. With tons of payload and insufficient mechanical strength, it is difficult for an airship to guarantee its flight reliability
