To address the core problem that the interfacial debonding between fiber and matrix determines energy absorption,a series of standard adhesion parameters are adopted to adjust the interfacial adhesion force of composite plates,and the interfacial delamination process is simulated based on the interfacial adhesion behavior and damage parameters.Simultaneously,using ABAQUS/Explicit,a high-speed impact damage analysis model of the ceramic/fiber composite bulletproof plate was established.Based on the analysis of the initial and residual velocities of the projectile,we investigated the relationship between structural components of the composite bulletproof plate, 收稿日期：2021-04-21 基金项目：国家重点研发计划资助项目(2016YFC0301402):山东省重点研发计划资助项目(2019JZZY010307)复合结构碳纤维防弹板的防弹性能仿真 秦溶蔓，朱    波苣，乔    琨，王东哲，孙    娜，袁晓敏 山东大学材料科学与工程学院，济南 250061 苣通信作者， E-mail: 82107918@qq.com 摘    要    针对纤维/基体间的界面脱黏决定能量吸收这一核心问题，采用一系列标准黏结力参数调整复合板界面黏合力，并通 过层间黏性行为和损伤参数模拟界面分层过程. 利用 ABAQUS 有限元软件中的 Explicit 分析模块建立陶瓷/纤维复合防弹板 的高速冲击损伤分析模型，通过分析弹丸初始速度与剩余速度，研究复合防弹板的各组分结构参数、纤维指标、铺层设计对 靶板及层合板抗侵彻行为的作用规律，并结合冯·米塞斯（Von-Mises）应力云图和基体损伤云图,探讨复合防弹板的受力与损 伤形式. 最后，利用弹道冲击实验成功验证了模型的准确性. 实验结果表明：由 13 mm 厚 SiC 陶瓷、5 mm 厚碳纤维复合材料 板和 17 mm 厚超高分子量聚乙烯纤维 (UHMWPE) 复合材料背板组成的复合防弹板可有效防御弹丸侵彻，对弹丸动能吸收和 弹速衰减作用明显. 关键词    碳纤维；陶瓷；复合防弹板；ABAQUS 有限元分析软件；冲击模拟；抗侵彻行为 分类号    TJ02 Simulation  study  of  the  protective  performance  of  composite  structure  carbon  fiber bulletproof board QIN Rong-man，ZHU Bo苣 ，QIAO Kun，WANG Dong-zhe，SUN Na，YUAN Xiao-min School of Material Science and Engineering, Shangdong University, Jinan 250061, China 苣 Corresponding author, E-mail: 82107918@qq.com ABSTRACT    Ceramic composite bulletproof armor is composed of hard ceramic and metal or fiber composite back plate and used as lightweight, protective armor to prevent the penetration of high-speed projectiles, such as armor-piercing projectiles. Presently, ceramic composite  bulletproof  armor  has  been  a  research  hotspot  in  military  protection.  Alumina,  boron  carbide,  silicon  carbide,  and  silicon nitride are commonly used as hard ceramic materials in ceramic composite bulletproof armor systems to resist projectile impact. High￾performance fibers, particularly carbon and ultrahigh-molecular-weight polyethylene (UHMWPE) fibers, are combined to improve the deformation resistance of the ceramic layer. Carbon fiber is a high-quality fiber with high specific strength and specific modulus. Carbon fiber  plays  an  important  role  in  ensuring  the  protection  stability  of  ceramic  bulletproof  plates.  The  energy  absorption  process  and absorption  mechanism  of  ceramic  composite  bulletproof  armor  are  complex  at  the  moment  of  resisting  projectile  penetration.  The simulation of the projectile penetration under different experimental conditions has always been the focus of bulletproof armor research.
