Plain-Woven, 600-Denier Kevlar KM2 Fabric Under Quasistatic, Uniaxial Tension

Abstract

We analyzed data from quasistatic, uniaxial tension tests on single-ply specimens of plain-woven, 600-denier KM2. Failure strains were found to range from 0.120 to 0.144 for warp-loaded and from 0.143 to 0.160 for fill-loaded tests. Failure stresses (strengths) ranged from 0.424 to 0.543 GPa for warp-loaded and from 0.593 to 0.642 GPa for fill-loaded tests. A least-squares fit, in the form of a rational function, was obtained to the second Piola-Kirchhoff stress vs. Green-St. Venant strain data for a representative warp-direction and a representative fill-direction test. In addition, averaged least-square fits to all the warp data and to data from four out of five fill tests were obtained, also in the form of a rational function. These fits are intended to inform constitutive modeling in numerical simulations.
