This report describes the laminated material in which the damping characteristics changes causing by Joule heating of the CFRP layer. The effect of fiber orientation angle and the quality of CFRP in the FRP division on the vibration characteristic were examined. The material effect of the insulator between aluminum and CFRP layers was also examined. The following results were obtained : If the high-temperature curing CFRP is combined, the damping character can be increased with a little reduction of the flexural rigidity. It is possible to make damping variable structural material with the wide heating temperature range, if a kapton film is made to be an insulating material instead of KFRP. It was shown that rapid vibration control was possible by temporarily putting the high electric power. It was clarified that the vibratory control was a possible by the change of natural frequency
