Quasi-Static Uniaxial Tension Characteristics of Plain-Woven Kevlar KM2 Fabric

Abstract

Quasi-static uniaxial tension tests were conducted on 30.8-mm-wide single-ply specimens of plain-woven DuPont Keviar KM2 aramid fabric (style 706). Six specimens were pulled along the warp direction, and six were pulled along the fill direction. The strength was found to range from 2.07 to 2.33 GPa, with a mean of 2.23 GPa in the warp direction and from 2.47 to 2.77 GPa, with a mean of 2.67 GPa in the fill direction. A bilinear, an exponential, and a quartic fit were obtained to the fabric stress-crosshead displacement curve from each test, with the quartic fit generally found to be the closest.
