Abstract:

The principle factors of concern in space environmental in so far as effects on materialsARE CONCERNED are believed to be 1 extremely high approaching absolute vacuum, 2 exposure to high and low temperatures, 3 actinic solar radiation, 4 other forms of high energy radiation such as cosmic radiation undiminished by atmospheric penetration, a d 5 particle bombardment from tiny meteorites. Initial studies on elastomers for sealing members in these systems were made in a temperature range up to 800 F while exposed to pressures in the range from 10 to the -5th to 10 to the -6th power mm of Hg. One of the most striking conclusions to be made is the stability of organic materials when subjected to these low pressures. Only very small losses of material were observed and these were almost completely due to known volatile constituents. Author
