An experimental investigation of the thermal contact resistance of bolt-joined aluminum honeycombs was conducted in atmosphere. The contact pressure in the junction with the bolt-joined honeycomb was determined by a pressure-measuring film. The thermal contact resistance of honeycombs across a bolted junction decreases with an increase of either the bolt torque or the number of bolts. The total thermal resistance of bolt-joined honeycombs increases with the specimen height and the cell size. An empirical correlation between the thermal contact resistance and the interfacial contact pressure was developed for the bolted honeycombs under various joint conditions. In addition, under the condition without using bolts the thermal resistances and effective thermal conductivities in three coordinates of the honeycomb were measured.
