Tailoring of Thermal Transition Temperature and Toughening of Shape Memory Epoxy Polymer

Abstract:

Shape memory epoxy polymer (SMEP-1) was modified by introducing ﬂexible epoxy into existing resin system. The thermal transition temperature (Ttrans) of shape memory polymer was tailored from 100°C to 76°C with the increase of the weight fraction of the flexible epoxy. The toughness of the polymer was also measured at the same time. The results show that the toughness of the polymer was improved especially at ultralow temperature. The addition of the flexible epoxy didn’t affect the excellent shape memory properties of the polymers.
