Quantification of deformation response at cyclic compression of polymer fibrous systems

The difficulty in qualitative evaluation of deformation properties of polymer fibrous assemblies lies in the fact that these materials differ from materials such as wood, concrete, steel, etc., as a consequence of the manifestation of non-linear and plastic deformation.

Summary:The difficulty in qualitative evaluation of deformation properties of polymer fibrous assemblies lies in the fact that these materials differ from materials such as wood, concrete, steel, etc., as a consequence of the manifestation of non-linear and plastic deformation. In this work, an attempt was made to quantify repeated compression performance of textile fibrous structures by using the concept of energy. Particular attention was paid to the nonelastic deformation of polymer fibrous systems under compression. Starting from the fact that the compression curve governs the energy-absorption characteristics of materials subjected to repeated stress, deformation components were determined by calculating the energy-absorbing properties and specific parameters – the irreversible compression work of all-cycle compression and the compression work of viscoelastic deformation of all-cycle compression. These parameters made it possible to estimate the compression hysteresis and then calculate the share of deformation components at lateral compression of polymer fibrous systems. [Display omitted] •Cyclic compression of polymer fibrous systems is evaluated.•Energy-absorption properties were used as a criterion of repeated stress performance.•Particular attention was paid to nonelastic deformation under compression.•The procedure for quantifying deformation response is explained.
