초록

This study proposes to develop a 3D printed re-entrant(RE) strip by shape memory thermoplastic polyurethanethat can be deformed and recovered by thermal stimulation. The most suitable 3D printing infill density conditionand temperature condition during shape recovery for mechanical behavior were confirmed. As the poisson’s ratioindicated, the higher the recovery temperature, the closer the poisson's ratio to zero and the better the auxetic properties. After recovery testing for five minutes, it appeared that the shape recovery ratio was the highest at 70oC. The temperaturerange when the shape recovery ratio appeared to be more than 90% was a recovery temperature of more than50oC and 60oC when deformed under a constant load of 100 gf and 300 gf, respectively. This indicated that further deformationoccurred after maximum recovery when recovered at a temperature of 80oC, which is above the glass transitiontemperature range. As for REstrip by infill density, a shape recovery properties of 100% was superior than 50%. Additionally,as the re-entrant structure exhibited a shape recovery ratio of more than 90%, and exhibited auxetic properties. It was confirmed that the infill density condition of 100% and the temperature condition of 70oC are suitable for REstripsfor applying the actuator.
