This work presents the research results regarding the ballistic response characteristics of monolithic ceramic armors. Two different configurations of armors are considered for investigation, aiming at identifying ways to increase the ballistic performance of Small Arms Protective Insert (SAPI). The first configuration consists of a monolithic ceramic tile (Al2O3) with a backing plate made of high-performance Kevlar-29 fiber reinforced composite; the second one has the same design as the first, but the monolithic ceramic tile is covered by a thin rubber layer. The impact behavior of the ceramic composite armors is analyzed numerically, using the finite element method. Some characteristic features, including the ballistic performance and the fracture conoid angle (for the ceramic tile) are discussed. The numerical models developed for the two armor configurations are validated by ballistic tests, where the projectile impact on the armors and the mechanical integrity of the armor systems after impact are observed. The results from simulations and experiments show that the Al2O3/Kevlar 29 composite armor is able to capture a 7.62 mm bullet with a striking velocity of 690 m/s and the rubber-ceramic composite armor is able to capture 5.56 × 45 mm bullet M855 (with an armor piercing tip) with an impact velocity of 894 m/s. It has been found that, when a rubber layer is placed on the front face of a ceramic composite armor, better ballistic performance is achieved. The experiments show that, when a rubber material is impacted by a projectile, its behavior at high velocities and high strain rates changes from elastic to brittle.

“…They demonstrated that most of the impact energy was absorbed by the face-sheets and the influence of the foam core was negligible at much higher impact velocities. Scazzosi et al 15 developed a finite element coupled to smoothed particle hydrodynamics model for the simulation of ballistic impact against a multi-layered armor system (Kevlar ® 29/epoxy cover, alumina tiles, and Kevlar ® 29/epoxy backing). They observed that complete perforation occurred at higher impact velocities and the damage extension increased with the impact velocity.…”

A numerical model for analysis of layer thicknesses on ballistic resistance of a multilayer armor

The interest in composite materials, which are lighter and have better mechanical properties (strength, fatigue resistance, corrosion resistance, etc.) than traditional engineering materials, is increasing day by day. In particular, their responses to low or high-velocity impact loads have been among the important research topics of recent years. In this study, unlike the traditional ceramic-based composite armor structures used in the defense industry, the effect of total carbon fibers specifically parallel oriented into impact direction on penetration resistance has been investigated, and penetration resistance of a multilayer hybrid composite armor which is composed of carbon fiber composite blocks sandwiched by two armor steel plates exposed to high-velocity impact has been analyzed numerically. Carbon fibers are normally very brittle to the transverse loading direction, contrarily, to their axial tension or compression direction. This is the reason why it is claimed that this high compression strength property of carbon fibers could be used as a layer in order to replace ceramics in add-on multilayer composite armor. The numerical model created in the ANSYS LS-DYNA program was verified by using the experimental data obtained in an earlier study. The verified numerical model was used to analyze high-velocity impact simulations of multilayer hybrid composite armor for different thicknesses of armor steel to reduce the areal density. By these simulations, minimum areal density compared to Rolled Homogeneous Armor steel for equivalent protection was finally achieved, and thus the hypothesis saying that carbon fibers parallel oriented to impact direction can give high penetration resistance was proved by showing that developed multilayer carbon fiber reinforced epoxy composite–armor steel hybrid panels have indicated a better protection level than STANAG 4569 Level-4 with a lower areal density.

“…In the case of impact projectile -protection panel, the use of properties without temperature dependence is justified for certain ranges of velocity and mass of the projectiles, by thermal cameras, by results of simulation using models presented in the literature [9], [10], [11], [12], [13], [14], [15], [16] and the characteristics of the materials the panels are made of, some of which (such as aramid or glass fiber composites) having constant properties over a fairly large temperature range. From the documentary study, the modeling of an impact bullet (9 mm or 7.62) in the range taken into account by the authors (100…400 m/s), is analysed as an isothermal event.…”

This paper presents a meso-level FE model of unidirectional yarns in order to point out the difference in impact response for two materials: glass and aramid fibers. The architecture is kept the same, successive layers of yarns, oriented 0° and 90°. The constitutive model for each yarn material is bilinear with hardening, as taken from recent documentation. The projectile is a 9 mm FMJ with the geometry close to the actual one and the metallic alloys for core and jacket are also bilinear with hardening. There were analysed the stages of the impact and failure process, the equivalent stress distributions on yarns and, based on the simulation results, the authors made recommendations for an actual design of a ballistic protection system.
