[0001] DESCRIPTION

[0002] A NOVELTY IN PERSONNEL CHEST ARMOR PLATES

[0003] TECHNICAL FIELD

[0004] The invention relates to a novelty in a chest armor plate, which is generally used by military or security personnel to provide protection against bullets, sharp objects and other dangerous objects.

[0005] In particular, the invention relates to a sponge chest armor plate comprising a geometric cavity, which prevents the internal stresses in the ceramic material from exceeding the strength values of the ceramic and prevents the formation of cracks in the ceramic material by preventing the localization of internal stresses and damping the energy generated during interaction.

[0006] STATE OF THE ART

[0007] The personnel chest armor plate is a piece of armor intended to protect the chest area, usually used by the military or security personnel. These plates are designed to protect against bullets, sharp objects and other dangerous objects.

[0008] The chest armor plates are usually manufactured with composite materials or ceramics and are used as an essential part of the personal armor systems. These plates are designed to maximize the security of the users by making rating according to different threat levels. In addition to the military units, it is also preferred by the personnel working in many fields such as police, private security and emergency services.

[0009] The vests with the integrated armor plates are specially designed to securely fix the armor. These vests offer an ergonomic structure so as not to reduce the user's mobility.

[0010] The most common material in modern personal armor systems is ceramic, which has high hardness properties but is inherently brittle. However, these ceramics can be severely damaged when subjected to high-speed impacts. In this context, the drop test that all personal armor systems must pass according to the NIJ 0101.06 standard is an important requirement for the ceramic-based chest plates. During these tests, the ceramic plates experience internal stresses, leading to crack formation and propagation. In order to avoid or at least reduce this situation, there is a need to develop a special foam geometry.

[0011] At the same time, ceramic armor systems can be exposed to adverse conditions when stacked, stored or transported by the end user. This can lead to deformation of the armor structure. The object of the design is to give the armor structure a certain resistance to adverse storage, stacking and transportation conditions.

[0012] In the state of the art, high velocity impacts can cause serious damage to the brittle ceramic materials. The drop tests applied to all personal armor systems in accordance with NIJ 0101.06 are critical to the durability and safety of the ceramic-based chest plates. During the tests, the internal stresses occur at the weakest points of the ceramic and these stresses can exceed the strength of the ceramic and cause cracks to occur. The size of the cracks and the amount of propagation increase depending on the weight of the plate and the number of drop tests. Furthermore, the formation of these cracks adversely affects the ballistic performance of the ceramic-based chest plates.

[0013] As a result, the need for a new armor plate structure that is economical, safe and useful for solving the above-mentioned problems existing in the state of the art and the inadequacy of the existing solutions necessitated a development in the relevant technical field.

[0014] OBJECT OF THE INVENTION

[0015] The present invention relates to a novelty in a chest armor plate, which is generally used for providing protection against bullets, sharp objects and other dangerous objects, which has been developed to eliminate the above-mentioned disadvantages and to bring new advantages to the relevant technical field. The most important object of the invention is to ensure that the dynamic interaction between the ground and the personnel protection armor during the drop test remains local and spreads the energy to be transferred to the ceramic over a wider area. In this way, it is aimed to keep the internal stresses below the strength limits of the ceramic and thus prevent crack formation.

[0016] Another important object of the invention is to enable thinner product designs. Thus, it was possible to produce products in the desired dimensions without using expensive solutions. This design has been observed to increase the strength of the final product during stacking, storage and transportation of the armor plates.

[0017] The structural and characteristic features and all advantages of the invention will be understood more clearly thanks to the figures given below and the detailed description written with reference to these figures. Therefore, the evaluation should also be made considering these figures and detailed description.

[0025] DETAILED DESCRIPTION OF THE INVENTION

[0026] In this detailed description, the preferred embodiments of the chest armor plate are described only for a better understanding of the subject and without any limiting effect. During the drop test, the internal stresses in the ceramic (20) material exceed the strength values of the ceramic (20) during the damping of the energy generated by the interaction of the peak of the ceramic-based chest plate with the ground and the transfer between the armor layers.

[0027] In these areas where crack formation is observed, the size and propagation of the cracks increase depending on the weight of the plate and the number of drop tests. This leads to a significant reduction in the ballistic performance of ceramic-based chest plate armors.

[0028] Fig. 1 shows the chest armor plate of the invention and its details. As a result of the R&D experiments carried out in our invention, a special sponge (30) geometry was designed with a cavity (31) in the middle thereof. Thanks to this sponge (30) geometry, the localization of internal stresses is prevented and the energy generated during the interaction is damped through the effective use of the sponge (30). Here, the cavity (31) is preferably located in the middle of the sponge (30) and is of rectangular structure from bottom to top. Thus, the ballistic performance losses of the ceramic-based chest plate armor are prevented.

[0029] Alternatively, the circular, square and different geometries of the cavity (31) can also be used in the invention.

[0030] There is also a plate of composite structure (10) on the back of the armor plate.

[0031] The scope of protection of this application is set out in the claims and cannot be limited to what has been described above strictly by way of illustration, and it is obvious that a person skilled in the art would be able to demonstrate the novelty set forth in the invention by using similar embodiments and / or to apply such embodiment to other areas of the art having a similar purpose. Therefore, it is obvious that such embodiments will lack the criterion of novelty and especially the criterion of exceeding the state of the art.
