| Popis: | Two-dimensional (2D) materials are competitive candidates replacing or supplementing conventional semiconductors due to their atomically uniform thickness. To observe and exploit the unique properties of two-dimensional (2D) materials, it is therefore vital to obtain clean and repeatable interfaces. Also, carbon, nitrogen, and boron nanostructures are promising ballistic protection materials due to their low density and excellent mechanical properties. In this study, we evaluated the ballistic properties of C3N and BC3 nanosheets against the hypersonic bullets with Mach number greater than 6. Besides, we created a hybrid sheet using van der Waals bonds between them based on the hypervelocity impacts of fullerene (C60) molecules utilizing molecular dynamics simulation. In the following, the ballistic properties of different structures were examined, and it was shown that C3N nanosheets have higher absorption energy than BC3 after C60 penetration. In contrast, in lower impact speeds and before penetration, single-layers exhibited almost similar behavior. Our findings also reveal that in hybrid structures, the C3N layers will improve the ballistic properties of BC3. The energy absorption values with a variable number of layers and interlayer distance are investigated, for homogeneous or hybrid configurations (stacking of C3N and BC3). In this work, we have discussed two interlayer distances of X = 3.4Å and 4X = 13.6Å for different configurations. These results provide a fundamental understanding of ultra-light multilayered armors' design using nanocomposites based on advanced 2D materials. It can also be used to select and make 2D membranes and allotropes for DNA sequencing and filtration. |
