以钛镍形状记忆合金（SMA）丝纤维和聚乙烯-形状记忆聚合物（SMP）片材为基体，制备了一种形状记忆复合材料（SMC）带。通过热机械试验研究了带的弯曲驱动特性。所得结果总结如下。(1)接近最大挠度的残余挠度通过在恒定最大挠度下冷却获得。在无载荷下加热，残余挠度消失。其形状固定率和形状恢复率均接近100%。(2)回复力是在恒定残余挠度下加热产生的。恢复力为最大力的93-94%。通过SMA和SMP的各种组合，期望SMC元件的高功能性的发展。
A shape memory composite (SMC) belt with a TiNi-shape memory alloy (SMA) wire fiber and a polyurethane-shape memory polymer (SMP) sheet matrix is fabricated. The bending actuation characteristics of the belt are investigated by the thermomechanical tests. The results obtained are summarized as follows. (1) Residual deflection close to the maximum deflection is obtained by cooling under constant maximum deflection. The residual deflection disappears by heating under no load. Both the rate of shape fixity and the rate of shape recovery are close to 100%. (2) Recovery force appears by heating under constant residual deflection. The recovery force is 93–94% of the maximum force. The development of high functionality of SMC elements is expected by various combinations of SMAs and SMPs.
