Development of Ballistic Protection from Composition Material on the Basis of Aluminum
In this paper a possibility of application of disperse-strengthened composite aluminum material as a ballistic protection is discussed. Experimental results of tests with bullet (PAB-9) are presented. Experiments were carried on with alloy based on A6 strengthened with aluminum oxide (Al2O3) particles. We present the experimental result of the development of welding technology of disperse-strengthened alloy Al-Al2O3 obtained with internal oxidation method. It was shown that under optimal conditions welding seam are free from macro-defects. We showed that the disperse-strengthened composite material as a part of ballistic protection exhibit significant increase of resistance against bullet penetration. This composite material can be used in structural elements because it does not suffer from destruction as opposed to ceramic materials. Mentioned above properties makes disperse-strengthened composite aluminum alloy a promising material for ballistic protection.
