In order to evaluate internal damage inside of carbon fiber reinforced plastic (CFRP) tubes by variation of thermal conductivity, a measurement device of thermal conductivity was developed from the viewpoint of measurement accuracy. The comparative static method was adopted as a measuring system for thermal conductivity, and the thermal conductivity was evaluated indirectly by the thermal conductivity of reference material in the method. In the present paper, CFRP tubes were subjected to impact loading, and the thermal conductivity was measured before and after the impact. The cross-section of CFRP tubes was also observed directly by optical microscope after the impact. As a result, the thermal conductivity was decreased by impact damage, and number of impact and number of impact points enlarge the decrease.
