In this research, the creep behavior of shape memory polymer (SMP) was researched. On this material, master curve of creep compliance was obtained, and time-temperature superposition principle was confirmed. The effect of physical aging on creep behavior was researched, too. The effect of physical aging on creep behavior was described on the aging shift factors, and the effect was depended on the change of time and temperature. From this result, time-physical aged time superposition principle was confirmed. Using the master curve and the shift factors of time, temperature and physical aging, it makes to be able to estimate the creep deformation including the effect of physical aging on creep behavior.
