摘要:

统计了工程中常用的55种P类膜材的规格参数，包括经纬向纱线密度、纤度、克重、厚度等，整理研究了团队累积的膜材力学性能检测数据，得到了涂层织物类膜材的基本力学性能数据库。在此基础上，利用多元统计方法中的经典方法对涂层织物类膜材组织结构参数及其相关试验结果进行分析，包括力学性能指标的相关性分析和力学性能指标的影响因素分析，确定各项参数对膜材强度指标的影响，采用二元线性回归分析方法，分别建立了P类膜材抗拉强度和撕裂强度的回归模型，可用于膜材生产和膜结构设计分析。

Abstract:

In this paper， the specification parameters of 55 kinds of coated fabric membrane materials commonly used in engineering at home and abroad are counted， including warp and weft yarn density， fineness， grammage， thickness， etc.. The mechanical test results accumulated were sorted out， and data of the basic mechanical properties of coated fabric membrane materials were obtained. The multivariate statistical method was used to analyze the structure parameters and test results of coated fabric membrane materials， including the correlation analysis of mechanical properties and the influencing factors of mechanical properties. The influence of various parameters on these strength indexes of membrane materials was determined， and the further linear regression analysis was conducted. The regression models of tensile strength and tear strength were established respectively， which could be further applied to membrane material production and membrane structure design.
