Abstract
This article presents the method of preparation a new type of ballistic armor based on hybrid silicone-ceramic (HSC) composites with considerable flexibility. An experimental study on the ballistic behavior of HSC composites connected with soft body armor is presented against FSP.22 fragments. The effect of Al2O3 ceramics on the ballistic performance of HSC composite was investigated, and the fragmentation resistance process of the composite armor combining the HSC composite and soft aramid insert is clarified. Furthermore, impact resistance tests made with a drop tower which allows for a gravity drop of a mass along vertical guides onto a sample placed with an energy of 5 J were performed. The results presented in this paper show that the HSC composites can be successfully used as a hard body armor. However, they do not exhibit the properties of absorbing the impact energy generated during the drop tower tests. The test results show that the ballistic performance of composite armors is influenced by the hardness and Young modulus of ceramics and soft body armor panel. Additionally, in the article, the results of mechanical properties of silicones used for preparation of composites were presented and compiled to determine their role in the performance of impact protection.
Highlights
The development of personal protection systems with improved ballistic performance and reduced weight has received a great interest in the last decade with the unfortunate ever-increasing threats and conflicts
To produce the hybrid silicone-ceramic composites, hexagonal ceramics made from aluminum oxide (Al2 O3 content 98%, CeramTec, Plochingen, Germany) were used
The obtained silicon-ceramic composites composites were were subjected subjected to impact forces generated at much lower velocities during falls that occurred during various types of physical activities
Summary
The development of personal protection systems with improved ballistic performance and reduced weight has received a great interest in the last decade with the unfortunate ever-increasing threats and conflicts. Ballistic protection systems are being increased in their functionality and technological aspects. Armor systems development works concern many sectors of the economy, including defense and security, where the key role is played by personal protective equipment (e.g., bulletproof vests, ballistic inserts, etc.). Their main objective is to provide adequate impact (ballistic) protection for the user who is exposed to the hazards of loss of life or health due to the nature of his or her work.
