This paper describes development of an active material based on a fiber reinforced metal and evaluation of its thermal deformation characteristics. In this study, the effect of heat-treatment on the thermal deformation characteristics of a SiC fiber/Al active composite of which SiC fiber filaments were non-uniformly distributed in the aluminum matrix was examined. As the result, the curvature of the active composite at room temperature was increased with increasing heating temperature and maximized at 833K. The curvature of the active composite at room temperature after heat-treatment was increased with increasing fiber volume fraction in the experimental range. The shape of the active composite at room temperature after heat-treatment was reproducible after heat-treatment at 833K.
