A new type of smart structural material is described in this paper. The characteristics of this material is its ability to utilize temperature dependency of the thermally induced deformation of an unsymmetrical laminated plate and to apply heat generated by Joule heating of CFRP laminas as energy of laminate deformation. The unsymmetrical laminated plates composed of aluminum alloy CFRP and KFRP sheets were used as the basic material. It was found that thermal control of the material was possible by the PID control method using Joule heating characteristics. The shapes of the material at the arbitrary Joule-heating temperature were calculated by Rayleigh-Ritz minimization of the total potential energy. These calculations were compared with the results of Joule-heating experiments, and good agreements were obtained. It was confirmed experimentally that the material showed several types of basic adaptive responses.
