Influence of different gauge length and strain rate parameters on tensile properties of Kevlar® 29 yarn

Abstract

The effect of gauge length and strain rate parameters on tensile properties of Kevlar®29 yarn has been studied. Six distinct gauge lengths have been subjected to a comprehensive evaluation of tensile properties. Similarly, five distinct strain rates are used to examine the strain rate’s effects. ANOVA has been carried out to analyse the co-relation between and with-in the tensile properties of Kevlar® 29 yarns samples. Experimental results indicate that the mechanical properties of Kevlar®29 are sensitive to gauge length and strain rate.
