Experimental study on thermal conductivity coefficient of clothing materials in especial environment

The cloth study of EVA spacesuit is one of the most important technology of the design of the whole EVA spacesuit, especially, its thermal characteristic will determine the safety and work efficiency of the astronaut. Therefore, basing on analyzing the thermal characteristic of weave, the thermal comfort of cloth and the principle of guarded hot plate apparatus, A double guarded hot plate apparatus has been designed to test the heat conducting coefficient of weave under especial environment (super low temperature, vacuum). Then, to summarize the research and give some advices and prospects.
