仿犰狳鳞片结构的躯干柔性防护装具抗穿甲燃烧弹侵彻性能
Penetration Performance of the Torso Flexible Protective Gear Inspired by Armadillo Scale Structure Against Armor-piercing Incendiary Bullets
摘要
Abstract
Based on the structure and morphology of the armadillo outer skin armor,this paper designed a bionic double-layer composite scale composed of SiC ceramic and ultra-high molecular weight polyethylene(UHMWPE)as well as a new type of flexible protective gear.The flexible protective gear consisted of an upper scale layer and a lower backing layer,in which the scale layer consisted of periodically arranged composite scales,and the cushion layer was made of UHMWPE layers.The flexibility test was carried out using the MTS C43 electronic universal testing machine,and ballistic tests were conducted in accordance with the ballistic protection performance requirements of standard Ⅲ in the"Military bulletproof vest safety technical performance requirements"(GJB 4300A-2012).Then,the influences of the thickness ratio of the composite scales,ceramic thickness,number of backing layers,and penetration position of the armor-piercing incendiary bullet on the protective performance of the torso's flexible protective gear ware analyzed,and the change process of the rigidity of the protective gear under concentrated load was discussed.The results show that the new type of flexible protective gear has good protective performance,and different penetration areas have a significant impact on the damage range;the cushion layer limits the bending deformation of the scale layer under concentrated load and reduces the overall flexibility.The research results of this paper can provide valuable references for the design and performance improvement of torso flexible protective gear.关键词
