In order to improve the thermal conductivity of space Carbon Fiber Reinforced Plastics (CFRP) shell structure, three techniques of enhancing thermal conductivity were designed, and vacuumthermal test was performed on the specimens which were treated according to these techniques, control group was prepared as well. These techniques include bonding high thermal conductivity film materials on the specimens’ surface and cladding multi layer insulation with high thermal conductivity film interlayers. According to test results, the technique of bonding carboncarbon composites film has an obvious advantage over the other two, increasing the thermal conductivity of CFRP shell structure by seven times. If this technique is used in conjunction with multi layer insulation cladded with high thermal conductivity film interlayer, better results can be achieved.
