Abstract
The shape-memory composite belt with a TiNi-SMA wire fiber and a polyurethane-SMP sheet
matrix was fabricated. The bending actuation characteristics of the belt were investigated by the
thermomechanical tests. The results obtained can be 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 shape-memory composite elements is
expected by various combinations of SMAs and SMPs.
