An Investigation of the auxetic behavior of weft knitted fabrics

Abstract

Auxetic materials exhibit extraordinary mechanical characteristics, displaying lateral expansion under axial tension and lateral contraction under axial compression- a behavior opposite to that of conventional materials. This unique property, attributed to their negative poisson's ratio (NPR), opens exciting possibilities for enhanced performance in various applications, including lightweight structures with superior energy absorption, fracture resistance, shear resistance, acoustic absorption, and variable permeability [1].
