Strength characteristic and failure criterion of Flexible Multi-Axial Warp Knitted Fabrics coated Polyurethane on single side
Coated fabrics are widely used in tension structures.In order to investigate the tensile behaviors of the coated fabrics,one group of specimens were cut out from polyurethane(PU)-coated multi-axial warp-knitted polyester fabrics.The failure strength of polyurethane-coated multi-axial warp knitted fabrics was obtained by the method of uniaxial tensile test and a mathematic model.The results show that the coated fabric is a kind of anisotropic material,and the coating has great influence on mechanical properties of the material.Furthermore,a failure stress criterion is presented for this material which can be used for references in material design and application.
