本文介绍了上海世博会中轴线屋面用聚四氟乙烯涂层织物的力学性能。首先，进行了多组偏心和双向拉伸试验，研究了试件的破坏机理和强度准则。然后，在不同的应变速率下对轴向样品进行测试，并确定应变速率、拉伸强度和断裂应变之间的关系。最后，研究了温度对力学性能的影响。结果表明，PTFE涂层织物具有典型的正交各向异性，其强度可用Tsai-Hill强度准则预测。拉伸强度和断裂应变与应变速率的对数呈线性关系。温度对力学性能影响不大，提出了温度折减系数用于设计和分析。
This article presents the mechanical properties of PTFE coated fabrics used in Central axis roof of Shanghai Expo. First, groups of off-axial and biaxial tensile tests are carried out, and the failure mechanism and strength criterion are studied. Then, on-axial samples are tested under different strain rates, and the relationship between strain rates, tensile strength, and strain at break are determined. Finally, the effects of temperature on mechanical properties are studied. Results show that PTFE coated fabrics are typically orthotropic and its strength can be predicted by the Tsai—Hill strength criterion. The tensile strength and strain at break show linear with the strain rate’s logarithm. The temperature has little effect on the mechanical properties and the temperature reduction factor is proposed for the design and analysis.
