Numerical and Experimental Research on the Impact of the Twaron T750 Fabric Layer Number on the Stab Resistance of a Body Armour Package
Journal Title: Fibres and Textiles in Eastern Europe - Year 2016, Vol 24, Issue 1
Abstract
The aim of the paper was to research how the depth of penetration in dependence on the fabric layer number used in the ballistic package is changed. During the research, the following methodology was adopted: the object of study was Twaron T750 fabric, specially dedicated for use in bulletproof vests. Then a numerical model consisting of 35 layers of fabric was established, from which the following parameters were selected for registration: depth of the knife’s penetration, displacement, velocity and acceleration. Then experimental studies were carried out which reflected the numerical model. In the next step a numerical model was validated and variants for the number of layers included in the package were created. The computing environment was commercial software LS-Dyna. Experimental studies were recorded using a super-high-speed camera - PhantomV12. The studies were conducted on the basis of the NIJ Standard -0115.00 norm.
