TR TR TR TR DESCRIPTION BALLISTIC CERAMIC STRUCTURE TECHNICAL FIELD The invention is particularly related to the ballistic ceramic structure used in protection systems against ballistic ammunition and/or armored vehicles in the fields of defense industry, security and military protection; It is related to the ballistic ceramic structure containing convex and concave surfaces, which increase the ballistic effective volume by connecting with each other, and which provide effective ballistic protection by interlocking the tiles with each other and preventing the formation of ceramic-free areas. KNOWN STATE OF THE TECHNIQUE Today, ceramic plates are used in armored vehicles or ballistic protection systems. Technically, the expectation from ballistic plates is that the plate is light and has high ballistic protection with a homogeneous distribution over the entire surface. In order to meet the expectations from ballistic plates, ceramic parts designed in different geometries, which are passed through various processes, are brought together to form a whole. The most commonly used conventional method is the hexagonal ceramic geometry. In this way, the gap between ceramics is minimized by creating a pattern structure on the panel. In the current technique, it is seen that in conventional ceramic arrangement methods, there is a damage area due to ballistic weakness at the junction points of the ceramics. These ballistic weakness points cause the desired homogeneous ballistic performance to not be achieved on the entire surface of the panel formed by the ceramic pieces and the ballistic level to decrease. In the current technique, in recessed ceramic part designs, it is observed that the adhesive component that fixes the ceramics together cannot enter through the ceramic joints and the adhesion performance decreases. In this case, it also causes ballistic vulnerability. In the application number CN107556012A in the current technique, a cylindrical domed geometry structure is used. Here, the ballistic resistance is high, but there is a ballistic weakness due to the non-ceramic area formed at the joints. Although it is used, there is ballistic weakness and difficulty in bonding at the joints. In addition, the geometry structure creates molding difficulties and reduces mold efficiency. As a result, in order to solve the above-mentioned problems existing in the current technique, the need for a new economical, useful ceramic plate with no protection weaknesses and the inadequacy of existing solutions have made it necessary to make a development in the relevant technical field. PURPOSE OF THE INVENTION The present invention is related to the ballistic ceramic structure, which has been developed to eliminate the above-mentioned disadvantages and bring new advantages to the relevant technical field, and which has no protection weaknesses in the joints used in protection systems against ballistic ammunition and/or armored vehicles. The most important purpose of the invention is to prevent the weakness experienced at edge and corner joints thanks to the angled and supporting geometry. Another important purpose of the invention is to prevent the formation of ceramic-free areas in the edge areas by interlocking the geometry. Another important purpose of the invention is to support the junction points of the three ceramics by the ceramics and to direct the ammunition into the ceramics thanks to the angle. In this way, it increases the ballistic performance of the panel. The structural and characteristic features and all the advantages of the invention will be more clearly understood thanks to the figures given below and the detailed explanation written by making references to these figures, and therefore the evaluation should be made taking these figures and detailed explanation into consideration.

Convex Transition. Concave Transition 16. Angle Between Surfaces DETAILED DESCRIPTION OF THE INVENTION In this detailed description, preferred embodiments of ballistic ceramic structure are explained only for a better understanding of the subject and in a way that does not create any limiting effect. In the invention, ceramic tiles (10) designed to be angled and supported by each other are arranged in a pattern to improve the ballistic performance of armored systems. The tile (10) has hexagonal geometry; There are 3 concave surfaces (11) and 3 convex surfaces (12). During the assembly of the tiles (10), the concave surface (11) and the convex surface (12) are connected to each other. All edges of the combined ceramic tiles (10) are supported by adjacent ceramic tiles (10). For this reason, while the effective volume to be used after the ballistic effect is increased, the effective thickness is not lost. At the same time, thanks to the angle (16) of the concave surface (11) and convex surface (12) elements, the destructive energy coming from the ballistic effect is transmitted to the neighboring tiles (10) at an angle, and the energy absorption feature is improved. In this way, higher performance products are obtained at lower thicknesses. In this case, it affects the weight of the armored panels. The angled (16) region between the surfaces, which is optimized in line with the threat for which the armor is designed, determines the active ballistic area of the armor. This angle directly affects ballistic performance. Figures 1 - 4 show the ballistic ceramic structure and details of the invention. In the invention, while the tiles (10) are brought together, the ballistic effective volume is increased by connecting the concave surface (11) and the convex surface (12) with each other. Thus, more effective protection is provided. The middle junction (13) located between the concave (11) and convex surfaces (12) is used to increase energy dissipation with non-sharp edges, to ensure the transition between the mentioned elements (11, 12), to ensure the passage of the adhesive to be used to fix the tiles (10) and to ensure the passage of the ceramic tile ( 10) It is used to ensure production adaptation and increase its strength. Likewise, the convex transition (14) and concave transition (15) between the concave (11) and convex surfaces (12) are made so that the adhesive material applied after the ceramic tile (10) arrangement can reach the lower surfaces and with this chamfer (15) on the edges. It is provided with the help of the space created during the alignment. In addition, these elements (14, 15) support the pressure shaping process of ceramic powder. In the invention, the angle (16) of the concave surface (11) and convex surface (12) elements directly affects the ballistic performance. This angle (16) is designed according to the threat and is effective in determining the ballistic effective area. Thanks to the middle joint (13) found in the invention, the ceramic tile (10) ensures that sharp corners within its effective volume and the destructive effect of these corners are avoided. The convex surface (14) located on two opposite corners of the invention and the concave surface (15) located on two opposite sides of the upper and lower surfaces of the invention are designed to increase performance during the adhesive application after the tiles (10) are brought together. Thanks to the convex transition (14), the applied adhesive can be transmitted from the upper surface to the lower surface of the tiles (10), while thanks to the concave transition (15), the adhesive can also be applied between adjacent ceramic tiles (10). The pattern structure is formed by the interlocking of the convex (12) and concave (11) structures of the ceramic tiles (10), and this structure ensures a more effective protection by naturally interlocking the tiles (10) and entering into each other. In addition, the tiles (10) are interlocked with each other, preventing the formation of ceramic-free areas in the edge areas. The scope of protection of this application is determined in the claims section and cannot be limited to those explained above for exemplary purposes. It is clear that a person skilled in the art can demonstrate the innovation put forward in the invention by using similar structures and/or apply this structure to other areas with similar purposes used in the relevant technique. Therefore, it is obvious that such structures will lack the criteria of innovation and especially surpassing the known state of the technology. TR TR TR TR
