Characterization of carbon nanotube yarn after exposure to hyperthermal atomic oxygen and thermal fatigue

摘要: Abstract Carbon nanotube (CNT)-yarn was evaluated for the survivability under hazardous space environmental conditions which were thermal fatigue, atomic oxygen and additive effect of these two exposures. Its tensile strength, tenacity, stiffness, strain to failure electrical conductivity characterized at extreme temperatures −150 120 °C before after exposure conditions. Tensile stiffness unexposed CNT yarn increased cryogenic temperature relative elevated temperature. There no change in properties when measured temperatures. Electrical decreased three environments involving but it had or small decrease exposed only. No fatigue followed by on CNTs’ observed. Considering low density 0.59 g/cc good resistant environment, CNT-yarns have potential applications spacecraft satellites.
