Modeling of Creep of Polymer Woven Fabrics

The processes of creep of woven materials are investigated. An industrial fabric, which is made on the basis of polymer threads, is chosen as an object of investigation. By analogy with the investigations of threads performed earlier the regions of linearity of viscoelastic properties of woven material are determined, fulfillment of the condition of similarity between the isochronous curves is proven, and the instantaneous stress-strain diagram is plotted. The similarity of viscoelastic nature between the woven material and threads, which form it, is shown. The possibilities of use of linear and nonlinear models of viscoelastic deformation for the description of creep of polymer fabrics are analyzed.
