深冷工况铝塑膜拉伸及抗疲劳性能的探讨

he tensile properties and fatigue resistance of two different types of aluminum-plastic films (moisture-proof layer of a product) in Jiangsu and Sweden were studied at room temperature and liquid nitrogen temperature (-196℃). The results show that the tensile properties of Swedish aluminum-plastic film are better than those of Jiangsu aluminum-plastic film at - 196 ℃; After 5000 bending tests, the surfaces of Jiangsu aluminum-plastic film and Swedish aluminum-plastic film were observed by SEM. There were micro defects on the surfaces of the two kinds of aluminum-plastic films. However, after the bending fatigue test, the tensile properties of Jiangsu aluminum-plastic film remained basically unchanged, and the tensile properties of Swedish aluminum-plastic film increased slightly, which showed that the fatigue resistance of Swedish aluminum-plastic film was better than that of Jiangsu aluminum-plastic film at low temperature..
