Study on elastomer simulated skin applied in measurement of extravehicular liquid cooling garment

A novel elastomer simulated skin was applied in the measurement of extravehicular liquid cooling garment and the satisfying result in improving the stability and heat dissipating capacity of garment was achieved. Firstly, five kinds of elastomer were selected, which were EVA, HTV, MSR, TPE and TPU. To evaluate the synthetic performance of these materials, a series of experiments characterizing material´s mechanical and thermodynamic properties was performed. The experiments included tensile and compression test, heat property test and so on. Meanwhile, fuzzy mathematic method was employed to analyze experimental parameters´ weight distribution, and then fuzzy decision-making method was adopted to perform synthetic evaluation. Above analyses showed that TPE had satisfying optimal performance and can be used as simulated skin in thermal manikin. Finally, to verify the function of TPE simulated skin, comparative experiments were performed in climate chamber when thermal manikin covered with simulated skin and did not cover with simulated skin. Results show that TPE simulated skin can improve the stability of thermal manikin and liquid cooling garment obviously, it can also effectively improve the heat dissipating capacity of liquid cooling garment.
