Abstract

In this study, single and multiple hybrid armour structures made of Armox 500T armour steel, Aramid/epoxy laminate composite, and Aluminium honeycomb materials were combined in a variety of configurations to investigate their ballistic performance. Ballistics tests were conducted using 7.62×51mm full metal jacket bullets with a muzzle velocity of 847 ± 10 m/s. The ballistic impact was made by shooting perpendicular to the striking surface of the plate. The ballistic test plates were 250×250 mm and their thickness varied based on the material configuration. Finite element analysis was conducted using the explicit time integration approach in the LS-Dyna software. The experimental study demonstrated that the armour structure consisting of monolithic steel and hybrid did not provide ballistic protection. However, with the hybridization of metal and composite sheets, the amount of energy absorbed from ballistic impact has increased. In addition, all armour combinations included in the research were tested in terms of weight and thickness, with the goal of determining their superiority over each other. The absorbed energy values achieved by hybridization exhibit a greater percentage increase compared to the increase in weight of plates. The finite element analysis results of the armour combinations were compared against experimental data, showing good agreement.

Armox 500T Zırh Çeliği İçeren Hibrit Zırh Plakalarının 7.62 mm Tam Metal Kaplama Mermi Karşısındaki Balistik Davranışının Deneysel ve Sayısal Olarak Araştırılması

Abstract

Bu çalışmada, Armox 500T zırh çeliği, Aramid /epoksi laminat kompozit ve Alüminyum bal peteği malzemelerinin tekli ve çoklu hibrit zırh yapıları çeşitli kombinasyonlarla bir araya getirilmiş ve balistik performansları araştırılmıştır. Deneysel çalışma, namlu çıkış hızı 847 ± 10 m/s olan 7.62×51 mm tam metal kaplama mermi ile balistik testler gerçekleştirilmiştir. Balistik darbe levhanın vurma yüzeyine dik gelecek şekilde atış yapılarak gerçekleştirilmiştir. Balistik test levhaları 250×250 mm boyutlarına sahip olup kalınlıkları ise malzeme konfigürasyonuna göre farklılık göstermiştir. Sonlu elemanlar analizi LS-Dyna programında açık zaman entegrasyonu yöntemi ile yapılmıştır. Deneysel çalışmalarda, monolitik çelik ve hibrit oluşan zırh yapısı balistik koruma sağlamamıştır. Bununla birlikte, metal ve kompozit levhaların hibritleşmesi ile sönümlenen balistik darbe enerji miktarı artırmıştır. Ayrıca, çalışmaya dahil edilen tüm zırh kombinasyonları ağırlık ve kalınlık açısından değerlendirilmiş birbirlerine üstünlükleri belirlenmeye çalışılmıştır. Hibritleşme ile elde edilen enerji sönümleme değerleri, plakaların ağırlığındaki artışa göre daha büyük bir yüzdesel artış sergilemiştir. Zırh kombinasyonlarının sonlu elemanlar analizi neticeleri deneysel veriler ile karşılaştırılması sağlanmış ve iyi uyum gözlemlenmiştir.
