## 1 Introduction
Four ceramic tile sizes were tested: 85 mm, 60 mm, 50 mm, and 33 mm, and obtained results showed that there is a crucial dimension of tile that should be used in a silicon carbide-based ceramic-faced mosaic armor system design to ensure its optimum performance. Another comparison of the ballistic performance was made over a series of additively manufactured alumina tiles placed over the back plate, which were investigated using both forward- and reverse-ballistic experiments. The results show some major differences between various types of tiles, increasing its ballistic performance along with the thickness [16]. In general, ceramic hard body armor systems consist of a hard brittle ceramic facing the projectile and a soft deformable backing material. The ceramic destroys the projectile tip, slows it down, and distributes the load over a large area of the backing. The backing supports the ceramics and brings the comminuted ceramics and the projectile to rest. The backing material is selected in structural, ballistic, and weight terms [15; 17]. Body armor still has a lot of problems related to weight, ergonomics (especially adjustment to the user's body and air permeability), scope, and area of protection and better energy absorption. For this reason, new solutions in the field of construction and materials are constantly sought to eliminate the above-mentioned disadvantages. In recent years, many solutions have been proved to be very efficient in providing superior ballistic performances and weight reduction [18; 19; 20; 21; 22; 23]. Among different hybrid composites, ceramic-polymer composite armors are particularly interesting for their high strength and light weight with high energy absorption capability. While the function of ceramics is to retard ballistic impact penetration, a polymer panel is to absorb high energy generation from the propagation of elastic/stress waves [24]. [PERSON] et al. [25] presented studies of composite layered systems based on monolithic armor ceramic tiles joined with polymer infiltrated ceramic foams which have been designed and evaluated for lightweight ballistic protection. Open cell silicon carbide foams of various cell sizes infiltrated with thermosetting or elastomeric polyurethane were used for this design. In addition, the state of the art research carried out in the field of flexible ballistic shields manufactured based on ceramic and/or elastomeric elements made it possible to indicate a patent application describing a method of making a product in the form of a composite ballistic plate absorbing and dissipating kinetic energy after impact with a high velocity projectile, intended for covers for vehicles or fixed objects. The plate comprises a layer made of individual ceramics pellets or a sintered refractory material. The pellets form regular rows and columns and are bound and held in the form of a plate by the solidified elastic material. A thermoplastic polymer such as polycarbonate or a thermosetting material such as epoxy resin is used as the bonding material. Moreover, the plate may contain layers of woven or non-woven textile material. However, due to its significant surface weight, thickness, and stiffness, this solution is not suitable for use in personal protective clothing [26]. Furthermore, based on the patent description No. PL 224825 [27], the possibility of producing a flexible armor intended for use mainly as an insert for bullet-proof and fragment-proof rests is specified. The armor consists of layers of ballistic textile material between which there is a layer composed of closed pouches, partially overlapping each other. The pouches are filled with STF (Shear Thickening Fluid) or MRF (Magneto Rheological Fluid). The armor provides resistance to penetration by 5.56-14.5 mm small and medium caliber armor-piercing shells and to penetration by fragments or an explosion. [PERSON] et al. [28] developed a body armor composite material which include a flexible liner, a polymer binder disposed on the liner, and ceramic solids embedded in the binder.
