| Abstract: | In this work, the thermomechanical behavior of NiTi, NiTiCu, CuAlNi, CuAlNiMn shape memory alloy (SMA) thin films deposited on Kapton polyimide substrate has been investigated. The actuation characteristics were studied using plate heating and Joule heating. Plate heating was utilized to realize the curvature/shape change of the developed SMA/Kapton composites during heating and cooling cycles. The SMA/Kapton composite developed with copper based SMA displayed rapid shape change beyond 150 °C and exhibited substantial displacement, which was not observed with NiTi based alloys. However, the hysteresis observed with NiTi SMA/Kapton composites was negligible as compared to CuAlNi alloys. Parameters such as voltage, load, and frequency were varied with Joule heating in order to analyze the thermomechanical properties in detail towards real time applications. Further the actuation behavior was corroborated with material properties such as surface morphology and stress-strain behavior. A conceptual design for Stewart platform and SMA belt exploiting the SMA/Kapton composite actuation behavior was proposed for various functional applications. © 2019 |
