Abstract

The invention provides a stratospheric aerostat skin and a production method thereof. The stratospheric aerostat skin sequentially comprises a weather-proof layer, a first gas barrier layer and a force bearing layer, wherein the first gas barrier layer comprises a graphene-resin layer comprising a first surface and a second surface far from the first surface, a first aluminized layer positioned on the first layer of the graphene-resin layer, and / or a second aluminized layer positioned on the second surface of the graphene-resin layer. The stratospheric aerostat skin adopts the graphene-resin layer as the main body structure layer of the first gas barrier layer, and the aluminized layers are introduced to the first surface of the graphene-resin layer and / or the second surface corresponding to the first surface respectively. Graphene has high heat conductivity, so the integral heat conduction performance of the stratospheric aerostat skin is obviously improved.

Description

technical field [0001] The invention relates to the technical field of aerostat manufacturing, in particular to a stratospheric aerostat skin and a preparation method thereof. Background technique [0002] The stratospheric aerostat is a new type of near-space multifunctional flying platform developed with the continuous development of science and technology. It is different from aircraft flying in the aviation layer, low-altitude aerostats, and satellites working in low orbits. It has a very wide range of military and civilian values, such as in missile defense, anti-terrorism, communications, remote sensing, space observation and Atmospheric measurement and other aspects have great application value. [0003] As the main structure of the aerostat, the performance of the skin directly affects the application performance of the aerostat. The flight altitude of stratospheric aerostats is generally around 18-24km. The air in this area is thin, and the density is about 1-14 o...
