Design and Preparation of Smart Adaptive Structure Made with SMA-SMP Composite

Abstract:

Shape memory composites (SMCs) combined with shape memory polymer (SMP) and shape memory alloy (SMA) having excellent mechanical properties and shape memory properties are considered to be ideal materials used in smart adaptive structure. In order to broaden the application of SMCs, a temperature controlled telescopic boom was designed and prepared. The design criteria indicated that temperature sequence was as follow: T _{room temperature}< T_g < A_s, and the deformation temperature was better around T_g+30°C. And the TiNi wires should be displayed in the longitudinal axe and outer race of the boom, and the minimum curved diameter of innermost layer could be calculated by. The recover behavior of the sample corresponded to the design, and the recover process could be repeated more than 10 times.
