Effect of Hybrid Structure of Ceramic/Fiber Composite Material on Penetration Resistance of Armor Plate

Armor systems made of ceramic and fiber composites are widely used to against armor-piercing bullets. As an important part of armor weapon system, the anti-impact capability of bulletproof plate is related to the security capability of armor weapon. The purpose of this paper is to investigate the interlayer hybrid effect of the fiber layer in the armor system and the influence of the position and thickness of the ceramic layer on the target's impact resistance. In the experiment, the penetrating behavior of the target plate was simulated by ABAQUS/Explicit using the 54 type 12.7 mm diameter penetrator as the impact body, combining silicon carbide ceramics, carbon fiber epoxy composite and UHMWPE fiber epoxy composites to form armor plates. The results show that the fiber interlayer hybrid mode has a great influence on the bulletproof effect of laminate. The penetration resistance of composite laminates with the optimal interlayer hybrid structure is better than single fiber composite laminates. The armor layer structure with ceramic layer laid in the middle of two fiber layers can achieve relatively ideal energy absorption effect. The armor plate with a total thickness of 10 mm uses the 8 mm ceramic can have the best ballistic resistance, but considering the manufacturing process and cost, 2 mm ceramic plate is the best choice. © 2020, Materials Review Magazine.
