战斗部爆炸瞬间产生的破片速度高、质量大，具有极强的穿透力，极易引爆弹药库、燃油舱等。液体（如水）有阻燃性且密度大，吸收高速破片效果显著。但高速破片冲击液体形成的冲击波、滞后流、气泡溃灭冲击波等复杂载荷，易引起液舱的整体破坏。在防护液舱内设置有空气层，可启到卸压减胀作用。为了可以抵御多次破片打击，将防护液舱设计成蜂窝状隔舱。为了减小液舱的深度，整体提升液舱的防护能力，在蜂窝状隔舱内设置Kevlar纤维管。综合各项功能构建“带卸压功能的Kevlar纤维管增强蜂窝状防护液舱”。通过对Kevlar纤维管、蜂窝结构、液体和空气舱的功能作用的研究, 建立破片打击该防护液舱的力学模型；掌握带卸压功能的Kevlar纤维管增强蜂窝状防护液舱的抗穿甲防护机理。形成带卸压功能的Kevlar纤维管增强蜂窝状防护液舱的设计与抗穿甲评估方法。

Warhead explosion instantly generate fragments with high-speed and high quality, which have a strong penetrating power and can easily detonated ammunition depots, fuel tanks and so on. Liquid (water) is characterized by flame retardancy and large density, and the ability of absorbing high speed fragment is remarkable. However, the shock wave, the hysteresis flow, bubble collapse load are generated during the impact of high speed fragments on liquid, which can lead to total destruction of the tank. An air layer is provided in the protective liquid tank, which can be opened to pressure relief inflation effect. In order to withstand multiple fragmentation blows, the protective liquid tank is designed as a honeycomb compartment. In order to reduce the depth of the tank and enhance the overall protective capacity tanks, the Kevlar fiber tube and the ceramic back plate are set in the honeycomb compartment. "Kevlar fiber tube reinforced honeycomb protection liquid tank with pressure relief function" is constructed with various functions. Through the research of the functional role of Kevlar fibers, honeycomb structures, liquids and air compartments, a mechanical model of fragmenting the protective liquid tank is established; armor piercing protection mechanism of Kevlar fiberglass reinforced honeycomb armor with pressure relief is investigated. At last, design and anti- penetration assessment method are provided with regard to Kevlar fiber reinforced honeycomb protection liquid tank with pressure relief function.
