ABSTRACT	The purpose of this study was to investigate the stiffness and the damping characteristics of smooth specimens of carbon/polyimide laminates which are subjected to the thermal cycles.The specimens were fabricated by three major aircraft companies in Japan.After being subjected to the thermal cycles,the damping was noted to increase about twenty precent whereas the stiffness decreased slightly.Small cracks due to the thermal cycles were observed in the 90°degree layers of the specimens.
