This paper concerns the ballistic resistance of hybrid composite shields. The analysis covers three types of two-layer composites. The first shield layer were plates of tungsten carbide (WC), ceramic balls Al2O3 (aluminum oxide 92) or steel balls (100Cr6 steel) embedded in a polymer matrix. The second layer was a laminate consisting of 10 layers of aramid fabric in a matrix of styrene-butadiene-styrene (SBS) copolymer. The study presents the analysis of damage caused by a ballistic impact, further compared to the results of computer simulations conducted using the finite element method (FEM). Samples were overshot along the ballistic track from the Beryl rifle. The 5.56 x 45 mm ammunition with the bullet of SS109 MESCO type was used. (C) 2017 Elsevier Ltd. All rights reserved.
