Problems solved by technology

[0004] However, the gas barrier properties of the existing envelope materials are poor, which makes the gas inside the aerostat or airship prone to leakage, thereby reducing the airborne time of the aerostat or airship
For the above problems, there is currently no effective solution

Abstract

The invention provides a bag skin material and an aerostat. The bag skin material comprises a weather-proof layer, an air-blocking layer, a weight-bearing layer and a welding layer which are overlapped, wherein the air-blocking layer is organic polymer with montmorillonite dispersed. The montmorillonite is dispersed in the organic polymer to form the air-blocking layer. Due to the property that the montmorillonite is layered crystalline silicate clay ore, the air-blocking performance of the bag skin material is improved. Furthermore, leakage of air inside the aerostat or an airship is reduced, and the hang time of the aerostat or the airship is lengthened.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a capsule skin material and an aerostat. Background technique [0002] Aerostat An aircraft that mainly relies on air buoyancy (or static lift) to overcome its own gravity to stay in the air or fly, such as high-altitude balloons and airships. Its main body is a bag that is filled with buoyant gas and has good airtightness. body. Therefore, for aerostats or airships, the performance of the capsule directly determines the success or failure of its mission, the load capacity and the flight cost. [0003] The capsule skin material (also known as the skin material) is the main structural material of the capsule body, which plays a role in maintaining helium and providing buoyancy. The capsule skin material is generally composed of high-strength, light-weight and high-gas-barrier polymer composite materials. For example, the Chinese patent publication number CN102416739A disclos...
