Abstract

The mechanical behavior of nylons 6,66,666,610,612,11 and 12 was studied using the method of thermally stimulated creep at 96°C. The resultant creep moduli were calculated. The strain recovery and strain recovery rates were measured and the retardation time spectra calculated as a function of temperature. The effects of humidity on the creep and subsequent recovery behavior were compared using samples conditioned to 0, 33, and 97% relative humidity at room temperature.
