This paper describes development of SiC fiber/aluminum active composites using continuous and/or discontinuous fiber. In this study, the effect of composite type on its tensile strength and curvature was examined. Though the curvature of the composite decreased with decreasing fiber length from 60 to 5 mm, curvature change during heating and cooling cycles between room temperature and 813 K were clearly observed. In order to increase the strength of the active composite, continuously reinforced layer and discontinuously reinforced one were bonded together. Tensile strength of this type became higher than the others and its curvature could also reproducibly change during the heating cycles due to the difference of fiber length. The curvature change of this type existed between continuous fiber type and discontinuous fiber type active composites.
