Benchmarking the penetration-resistance efficiency of multilayer graphene sheets due to spacing the graphene layers

Abstract: In this paper, the penetration-resistance efficiency of single-layer and multilayer graphene sheets has been investigated by means of the multiscale approach. The employed multiscale approach has been implemented by establishing a direct correlation between the finite element method and the molecular dynamics approach and validated by comparing its results with those of the existing experimental works. Since by using numerous techniques, a new class of graphene sheets can be fabricated in which the graphene la… Show more

“…Because of the partially overlapping GO flakes, radial stress waves can propagate significantly farther through the composite since the in-plane speed of sound of GO flakes can be considerably faster than that of SF due to higher Young’s modulus of GO ( E GO ∼ 207.6 GPa) than that of SF ( E SF ∼ 4.1 GPa), where the speeds of sound is proportional to √ E . Therefore, the abrupt increase at 100% areal coverage can be accredited to the impact energy delocalization by the elastic wave propagation through the connected GO flakes …”

“…Therefore, the abrupt increase at 100% areal coverage can be accredited to the impact energy delocalization by the elastic wave propagation through the connected GO flakes. 49 E d *, the difference between E p * and v i 2 /2, indicates how efficiently the material can dissipate penetration energy through the delocalization process along the in-plane direction. Because this redirection of energy flow from the normal to tangential direction is highly desired in an armor to achieve the same antiballistic performance with less material, E p * of pure SF and GO-SF composites were compared with other microscopic and macroscopic materials from previous literature (Figure 5c).…”

“…Using molecular dynamics (MD) method, Abdol et al [32] built a three-dimensional graphene networks via silicon ion beam irradiation. In a series reports by Sadeghzadeh [34,[39][40][41][42] , the graphene sheets were impacted with various kinds of high speed projectiles, and the effects of several parameters on the rupture form and penetration-resistance efficiency of the graphene ribbons were evaluated systematically. In the experiments by Eller et al [43] , few layered graphene were bombarded with golden nanoparticles, and the ejection of ions from graphene were characterized.…”

“…Even in very low concentrations, graphene can greatly enhance the ability of electrical charge to flow in a material [11]. Recently, numerous researches have been carried out to study the impact behavior of graphene [12,13] as well as resistance rupture and creation of nanopore in graphene [14][15][16][17]. The results demonstrate that graphene sheets can be used as bulletproofing due to its ultrahigh strength.…”
