Description

TECHNICAL AREA

[0001] The invention relates to a ballistic ceramic structure used in protection systems for ballistic munitions and / or armored vehicles in the fields of defense industry, security and military protection.

[0002] In particular, the invention relates to a ballistic ceramic construction having convex and concave surfaces that increase the ballistic effective volume by bonding them together and that provide effective ballistic protection by bonding the plates together and preventing the formation of a ceramic-free area. State of the art

[0003] Today, ceramic plates are used in armored vehicles and ballistic protection systems. Technically, ballistic plates are expected to be lightweight and offer high ballistic protection with a uniform distribution across the entire surface. To meet these requirements, ceramic parts in different geometries, which are subjected to various processes, are joined together to form a single unit. The most commonly used conventional method is the hexagonal ceramic geometry. This creates a patterned structure on the plate and minimizes the gap between the ceramics.

[0004] The present technique demonstrates that with conventional ceramic assembly methods, a damage zone arises due to ballistic weaknesses at the ceramic joints. These ballistic weaknesses result in the desired homogeneous ballistic performance not being achieved across the entire surface of the plate consisting of ceramic components, resulting in a reduction in ballistic performance.

[0005] In the designs of recessed ceramic parts in the present technique, it is observed that the adhesive component holding the ceramics together cannot penetrate into the ceramic joints, resulting in a deterioration in adhesion. In this case, it also leads to a ballistic vulnerability.

[0006] Application CN107556012A uses a cylindrical, curved geometry. Here, the ballistic resistance is high, but there is a ballistic weakness due to the non-ceramic region that forms at the joints.

[0007] Although the hexagonal geometry is used in the present application, US8833229B2, there are ballistic weaknesses and bonding difficulties at the joints. Furthermore, the geometry structure leads to molding difficulties and reduces mold efficiency.

[0008] The need for a new economical, useful, non-protective ceramic plate to solve the above-mentioned problems existing in the existing technology and the inadequacies of the existing solutions made a development in the relevant technical field necessary. OBJECT OF THE INVENTION

[0009] The present invention relates to a ballistic ceramic structure developed to eliminate the above-mentioned drawbacks and to bring new advantages in the technical field concerned, and which does not present any protective weaknesses in the compounds used in ballistic ammunition protection systems and / or armored vehicles.

[0010] The main aim of the invention is to avoid weak points in edge and corner connections due to the angle and support geometry.

[0011] Another important objective of the invention is the interlocking of the geometry to prevent the formation of ceramic-free areas at the edges.

[0012] Another important goal of the invention is to support the joints of the three ceramics and to guide the ammunition into the ceramics using the angle. This improves the ballistic performance of the plate.

[0013] The structural and characteristic features and all advantages of the invention will be better understood from the following figures and the detailed description made with reference to these figures, and therefore the evaluation should be made taking into account these figures and the detailed description.

[0014] In this detailed description, the preferred embodiments of the ballistic ceramic configuration are described only for the purpose of better understanding of the subject matter and are not limiting in nature.

[0015] According to the invention, ceramic plates (10) designed to be angled and mutually supportive are arranged in a pattern to improve the ballistic performance of armor systems. The plates (10) have three concave surfaces (11) and three convex surfaces (12) in a hexagonal geometry. During assembly of the plates (10), the concave surfaces (11) and the convex surfaces (12) are bonded together. All edges of the bonded ceramic plates (10) are supported by the adjacent ceramic plates (10). Therefore, the effective thickness is not lost, while the usable volume after impact is increased. At the same time, thanks to the angle (16) of the elements with the concave surface (11) and the convex surface (12), the destructive energy resulting from the ballistic impact is transferred at an angle to the adjacent plates (10), and the energy absorption property is improved.This allows for higher-performance products with reduced thicknesses. This reduces the weight of the armor plates. The range of the interface angle (16), which is optimized depending on the threat the armor is designed to resist, determines the active ballistic surface of the armor. This angle directly impacts ballistic performance.

[0016] The Fig.1-4 illustrate the structure of the ballistic ceramic and details of the invention. According to the invention, when the plates (10) are joined together, the effective ballistic volume is increased by the contact of the concave surface (11) and the convex surface (12). This ensures more effective protection. The central joint (13) between the concave (11) and the convex surface (12) serves to increase energy dissipation at blunt edges, to create the transition between the aforementioned elements (11, 12), to create the transition of the adhesive to be used for attaching the plates (10), and to increase the production adaptability and strength of the ceramic plate (10).Likewise, the convex transition (14) and the concave transition (15) between the concave (11) and convex surfaces (12) are created using the adhesive material applied after laying the ceramic tile (10) to reach the lower surfaces and the gap formed during laying with this chamfer (15) on the edges. Furthermore, these elements (14, 15) assist the compression molding process of ceramic powder. Within the scope of the invention, the angle (16) between the concave (11) and convex (12) surface elements has a direct impact on ballistic performance. This angle (16) depends on the threat and is effective for determining the ballistic effective area.

[0017] Thanks to the central joint (13) according to the invention, the ceramic plate (10) avoids sharp corners within its useful volume and the destructive effect caused by these corners.

[0018] The convex surface (14), located at two opposite corners of the invention, and the concave surface (15), located at two opposite edges of the top and bottom of the invention, serve as power amplifiers during the application of the adhesive after the plates (10) have been joined together. The convex transition (14) enables the application of the adhesive from the top to the bottom of the plates (10), while the concave transition (15) enables the application of the adhesive between adjacent ceramic plates (10).

[0019] The pattern structure is formed by the interweaving of the convex (12) and concave (11) structures of the ceramic plates (10), and this structure provides more effective protection by naturally sealing and interpenetrating the plates (10). Furthermore, the interlocking of the plates (10) prevents the formation of ceramic-free areas at the edges.

[0020] The scope of this application is defined in the claims and cannot be limited to what is described above purely by way of example. It is obvious that one skilled in the art can introduce the innovation presented in the invention by using similar embodiments and / or apply this embodiment to other areas with similar purposes used in the relevant field. It is therefore clear that such organizations do not meet the criterion of novelty and, in particular, the criterion of exceeding the prior art. QUOTES CONTAINED IN THE DESCRIPTION
