THE THERMAL CONDUCTIVITY OF HONEYCOMB SANDWICH PANELS WITH CARBON FIBRE PLATES AT LOW TEMPERATURE

The measuring of thermal conductivity of honeycomb sandwich panels with carbon fibre plates has been carried out. The results of T、L、W directions have been measured and compared. The effect factors and mechanism of thermal conductivity of honeycomb sandwith panels with carbon fibre plates have been analyzed and discussed. The main change law of the thermal conductivity of honeycomb sandwich panels at low temperature has been found.
