本文通过对9种国产G类膜材进行双轴拉伸试验，研究了双轴拉伸弹性模量与单轴极限抗拉强度以及各项技术参数之间的相关性. 结果表明，9种膜材的经向弹性模量均大于纬向，泊松比均大于0.5. 抗拉强度、纱线密度、基布面密度、膜面密度和厚度与弹性模量呈正相关，纤维直径与弹性模量呈负相关. 线性回归分析显示，单一因素并非能决定弹性模量，而是多因素相互作用的结果，为膜材多尺度分析和参数化设计提供科学依据.

In this paper, the biaxial tensile tests of nine types of domestic G-type membranes were carried out, and the correlation between the biaxial tensile elastic modulus and the uniaxial ultimate tensile strength and various technical parameters was studied. The results show that the warp elastic modulus of all nine membranes was greater than the weft, and the Poisson's ratio exceeded 0.5. Tensile strength, weave count, fabric areal density, membrane areal density and thickness were positively correlated with the elastic modulus, and the fiber diameter was negatively correlated. Linear regression analysis revealed that the elastic modulus is not determined by a single factor but is the result of the interaction of multiple factors, providing a scientific basis for the multi-scale analysis and parametric design of the membranes.
