Development of Ballistic Protection from Composition Material on the Basis of Aluminum

Abstract

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-Al2O3obtained 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.

Effect of Nano Al_2O_3 Addition and T6 Heat Treatment on Characteristics of AA 7075 / Al_2O_3 Composite Fabricated by Squeeze Casting Method for Ballistic Application

“…In order to achieve the ballistic resistance characteristic, the materials can be engineered to combine every mechanical strength each element has in a form of composite. [3][4][5] Aluminum series 7 is a type of aluminum alloy containing 1-8% Zinc as the main alloying element. The addition of Zinc is intended to improve the strength of the alloy with a precipitation hardening method, besides Zinc can also improve the corrosion resistance of an alloy.…”

“…It should be thereat appreciated that armor for equipment used for the hull but not for elements of additional armor-plating implies the performance of quite a great number of welded joints, both when manufacturing equipment and during the operation and repair thereof, which makes the issue of increasing productivity and improving the welding quality be urgent [13,14].…”
