THE INFLUENCE OF ENVIRONMENT ON STATIC FATIGUE OF POLYMERS

Abstract

The effects of several gaseous environments on the static fatigue of nylon 6.6 and atactic polystyrene filaments were studied. Considerable care was taken to reduce the influence of light, temperature fluctuation, vibration and contamination, all of which may affect the life of materials under stress. No statistically-significant difference in stress lives could be attributed to the environments studied, namely, humid air, dry air, dry nitrogen and vacuum for both materials at 30 deg C and humid air, dry air and dry nitrogen at 50 deg C for nylon.
