Mechanical properties and buckling analysis of woven fabric

The buckling of a woven fabric influences its performance throughout processing and during actual use. In addition, this phenomenon reflects on the recovery of the textile–polymer composites. The mechanics of the buckling behavior of woven, knitted or non-woven fabrics have a large number of different approaches, and the obvious inconsistency of applying the classical beam theory to the textile problem remains. The buckling of textile materials is a deciding factor of their drape and conformability. Fabric buckling also defines the ability of a fabric to fit to a different shape object without wrinkling. An empirical approach foundation to quantitatively compare the buckling of existing and new flexible textile materials, no matter what their composition, was developed. The buckling coefficient was found to be highly correlated to the fabric modulus of rigidity, fabric Young's modulus and fabric weave design. For the twill structure, the value of twill line angle to the direction of buckling force has a significant effect. In this paper, the buckling of woven fabric with or without holes was analyzed. It has been proven that major modes of deformation in the buckling of fabrics with holes are fabric bending rigidity, fabric design and the ratio of the volume of the hole to sample volume.
