摘要：

Coated fabrics are widely used in tension structures. In order to investigate the tensile behaviors of the coated fabrics, one group of specimens was cut out from multi-axial warp-knitted polyester fabrics coated with polyurethane on one side. These failure strengths of polyurethane-coated multi-axial warp-knitted fabrics were obtained by the method of uniaxial tensile test and a failure stress criterion is presented for the kind of materials. The results show that the coated fabric is anisotropic material, and the coating has great influence on the mechanical properties of the material. Furthermore, the failure stress criterion can be used for references in material design and application.
