Material design and test verification of high impedance composite membrane of water container used in Chinese Space Station

A novel high impedance composite membrane material has been developed to satisfy the save demand of many kinds of space liquid medium in Chinese Space Station. Considering the high gas-resistance and water-resistance, and its compatibility with the liquid in Space Station, the composite membrane was skillfully designed using 9 layers materials. The compatibility experiment and mechanical properties experiment showed that the high impedance composite membrane has good compatibility with the liquid in Space Station, excellent heat-proof property, melted property, physical and mechanical properties, high gas-resistance and water-resistance property and great chemical corrosion-resistance property. The high impedance composite membrane material offers a new method for the design and application of inner-bag type water container in Space Station. (paper)
