The study of stab resistance of dry aramid fabrics

Abstract

The paper presents the issue of a knife proof ballistic package. This issue was emphasized since most of modern vests are de-signed to match the threat posed to them only by firearms. There was observed negligence of protection against melee attacks. There is, thus, a need to develop a research methodology in this matter, because it is a valid and necessary problem in a modern developed so-ciety. The aim of this study was to perform a numerical model which simulated the phenomenon of penetration of a ballistic package by an engineering blade. Specification of an engineering blade was taken from standard NIJ Standard-0115.00. Commercial software LS-DYNA was used to carry out the analysis.
