    ЗАБЕЗПЕЧЕННЯ НЕОБХІДНОГО РІВНЯ ЗАХИСТУ І КОНТРОЛЬ ЗАХИСНИХ ВЛАСТИВОСТЕЙ КЕРАМІКО-ПОЛІМЕРНИХ БРОНЕЕЛЕМЕНТІВ. PROVIDING THE REQUIRED LEVEL OF PROTECTION AND CONTROL OF THE PROTECTIVE PROPERTIES CERAMIC-POLYMER ARMOUR ELEMENTS

    Recently, light-armoured ceramics and combined materials containing layers of ceramics and polymer composites have been increasingly developed. According to the cost indicators, the possibility of using raw materials of domestic production, specific weight and high protective properties of the most acceptable for Ukraine ceramics from silicon carbide. When developing and manufacturing armoured structures, both for individual protection and vehicle protection, the greatest attention is paid to the physical and mechanical properties and specific weight of ceramics, but a clear relationship between mechanical properties and ballistic efficiency has not yet been established. Manufacture of ceramic-polymer protective products has the following mandatory stages of quality control: input control of materials, 100 % control of weight, geometric dimensions, protection area, availability of internal defects with the help of X-ray defectoscopic method. Thus, proper quality control at all stages of ceramic and polymeric protective products manufacture makes it possible to guarantee the necessary level of protective properties. However, it should be noted that ballistic tests have been and remain the necessary and most reliable method of monitoring the protective properties of armour protection products. Ballistic tests are carried out according to standard methods in accredited laboratories in the quantity approved for certain types of tests (certification, presentation, acceptance, periodic, etc.). World experience in developing and manufacturing armour-plated materials and structures shows that the implementation of high resistance to dynamic loads while maintaining the weight advantages (especially for individual protection and defense of aircraft) is associated with the use of ceramic elements with reactively baked silicon carbide or hot-pressed boron carbide (lighter than silicon carbide, but more valuable). Ballistic tests with the use of validated methods and ensuring the repeatability of the method remain necessary and the most reliable method of monitoring the protective properties of armour protection products.
