This paper describes development of a FRM based actuator material. In this study. continuous SiC fiber reinforced aluminum composite was laminated with unreinforced aluminum plate by the interphase forming/bonding method using copper insert foil. The material was curved by cooling from the hot pressing temperature and the curvature at room temperature was almost maximized by investigating the effect of thickness of the aluminum plate, inter-fiber spacing and length of the material. The curvature was decreased by heating and became zero at the temperature of about 580K. This temperature and the curvature at room temperature after thermal cyclings were reproducible and were the same even after ten cycles, so availability of this material as an actuator was ascertained. It was also clarified that the copper concentrated around the SiC fiber which was introduced by the interphase forming/bonding method contributed to the increase of curvature of the actuator.
