Study On Anti-jet Performance Of Ceramic Panel Reaction Armor

Ceramic materials with high hardness,high compressive strength,high temperature and low density and other satisfactory mechanical properties,in the past 30 years has been widely used in armor protection applications.Compared with the metal material,the ceramic material for the jet of each speed has a high degree of protection.So at this stage to carry out the ceramic panel explosion reaction armor anti-jet performance research,and with the homogeneous steel panel explosion reaction armor comparative analysis of the new explosive armor and even the development of new armor protection has important engineering application value.Firstly,the failure mechanism of ceramic materials under impact loading and the interference mechanism and model of ceramic materials to jet are studied.The results show that the main reason for the strong anti-jet performance of ceramic materials is the lateral interference of the jetting phenomenon rather than the intensity of the jet.Secondly,the interference effect of the armor with the same surface density of the ceramic panel explosion reaction armor and the homogeneous steel panel explosion reaction armor is compared.The simulation results show that the interference effect of the armor on the same surface density of the AL2O3 ceramic panel is better than that of the homogeneous steel panel.The numerica simulation model of the explosive reaction armor of 3/3/3 type ceramic panel and steel panel was established respectively.The superiority of the ceramic panel reaction armor was observed and the experimental results were verified.Reliability of numerical simulation.Finally,the interference effect of the armor against the jet with the total thickness of the ceramic panel is studied.The jet velocity,the diameter of the head and the remaining depth of the post-effect target are analyzed,and the appropriate explosive reaction armor structure is explored to achieve the best interference effect on the jet.
