    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.

    МОЖЛИВОСТІ ВДОСКОНАЛЕННЯ ТЕХНІЧНОГО ЗАБЕЗПЕЧЕННЯ ЕКСПЕРТНО-КРИМІНАЛІСТИЧНИХ ПІДРОЗДІЛІВ МВС УКРАЇНИ ДЛЯ ВИКОНАННЯ СУДОВО-БАЛІСТИЧНИХ ДОСЛІДЖЕНЬ. OPPORTUNITIES FOR THE IMPROVEMENT OF TECHNICAL SUPPORT OF THE EXPERT-CRIMINALISTIC DEPARTMENTS MIA UKRAINE FOR THE FULLFILLMENT OF FORENSIC AND BALLISTIC RESEARCHES

    The testing department of the State Research Institute of the Ministry of Internal Affairs of Ukraine is accredited by the National Accreditation Agency of Ukraine for competence and independence in accordance with the requirements of DSTU ISO / IEC 17025: 2006 (General Requirements for the Competence of Testing and Calibration Laboratories), has the status of conformity assessment body in fields: testing of armor, weapons, special non-lethal weapons, ammunition and structurally similar items, pyrotechnic articles. For the control of the ballistic stability of personal protective equipment (bulletproof vests and bulletproof vest elements, shields and helmets bulletproof), protective glazing, protective structures (parts and components), protection of armored specialized vehicles, riflescale shotguns, smooth barrels of the appropriate caliber, which provide the required, determined by regulatory documents of Ukraine, the speed of the bullet and cartridges of the industrial production. Necessary weapons or ballistic barrel are grounded on the developed and patented at the State Research Institute of the Ministry of Internal Affairs of Ukraine weapons for remote shooting weapons [1]. The scope of use of this device is not limited to the ballistic tests of armor protection conducted in the State Research Institute of the Ministry of Internal Affairs of Ukraine, but may be used, for example, in the Expert Forensic Departments of the Ministry of Internal Affairs of Ukraine. One of the most important issues raised by a forensic expert is the determination of the propriety of improvised firearms and ammunition and their suitability for firearms and ammunition. In this regard, the Methodology for establishing the object of a firearm and its suitability for firearms (hereinafter – Methodology) contains relevant regulations. Thus, in particular, Clause 3.1 of the Methodology provides that the object of the requirement to firearms is determined by the presence of a set of a number of common forensic features: Clause 7.4.8 of the Methodology contains the relevant regulations, it is mentioned that the experimental firing is carried out by use of a remote control firing, equipment (devices) to determine the flight speed of shells or their kinetic energy and a bullet trap or target that provide effective inhibition of projectiles fired from small arms. In our opinion, the solution of this problem and, consequently, the improvement of the technical support of conducting dynamic tests during the performance of forensic ballistic investigations, consists in the cooperation of the units of the Expert Service of the Ministry of Internal Affairs of Ukraine with the State Research Institute of the Ministry of Internal Affairs of Ukraine (hereinafter – the Institute).
