This paper describes fabrication of an active composite working at high temperatures. In this study, the concept of SiC/Al active composite was applied to nickel matrix composite. In this case, SiC/Ni layer was laminated on unreinforced nickel plate with aluminum insert. Fabrication condition of this material was examined and an appropriate condition, that is, hot pressing temperature 993 K, pressure 27 MPa, time 4.8 ks in a low vacuum of 1×10^2 Pa using 0.1 mm thick insert was obtained. There remained a thick interaction layer of NiAl intermetallic phase around the bonded line of this material. The curvature of this composite increases with increasing temperature up to higher than 1200 K, which shows the possibility of it as an active material working at high temperatures.
