Abstract

The effect of various weaving types for fabric composites on the low-speed (up to 350 m/s) penetration into multilayer fabric barriers made of aramid fibers is studied. The geometric properties of plain and twill weaves are taken into account on the basis of experimental data showing that the warp and weft threads may have different elastic and ultimate properties. Significant differences in the parameters of interlayer friction are also taken into account for the fabrics of various weave patterns. The results of full-scale experiments for the penetration into four-layer and ten-layer fabric barriers are used to verify the models of penetration into fabric barriers and to study the penetration into composite fabrics with various mutual arrangements of plain and 3/3 twill weaves. It is shown that some particular laying methods based on layer alternations can improve the protective properties of multilayer fabric barriers.
