Abstract

The method of generating the most practicable shape recovery force in smart composite materials which embedded shape-memory alloy (SMA) fiber under the resin matrix is electric heating. However, because the calorie for the heating of the resin matrix increases in the low temperature environment, it is necessary to control the electric heating corresponding to an ambient temperature to obtaining a steady shape recovery force. In this paper, the main factor which influences the shape recovery force is reviewed first. And, it reports the shape recovery force control system by the electric heating which makes the contribution of composite materials which combine SMA that the phase transformation temperature is different to the stability improvement to the operation environment, and the SMA fiber a strain sensor to be possible.
