目的 为探究不同树脂基复合材料靶板对高速破片的抗侵彻性能,筛选出抗侵彻最优组合,为防护材料的结构选型与优化设计提供理论依据。方法 基于LS-DYNA软件建立高速破片侵彻有限元模型,采用数值模拟方法开展仿真分析。选取碳纤维增强环氧树脂复合材料(CFRP)、碳纤维增强聚醚醚酮复合材料(CF/PEEK)、超高分子量聚乙烯增强环氧树脂复合材料(UHMWPE/EP)以及芳纶增强环氧树脂复合材料(AF/EP)4种树脂基复合材料,设计4种靶板组合:以CF/PEEK为迎弹面分别与 CFRP、UHMWPE/EP、AF/EP复合,另以CFRP为迎弹面与CF/PEEK复合。针对1.1 g柱状楔形破片,在2 000 m/s的冲击速度下开展侵彻仿真,破片损伤行为采用Johnson-Cook失效准则进行描述,4种树脂基复合材料的冲击损伤特征均采用Chang-Chang失效准则进行评估。结果 仿真结果表明,以CF/PEEK为迎弹面,CFRP为背弹面的靶板抗侵彻性能最优:该组合下破片动能可在12 μs内降为0 J,背弹面最大变形量仅为2.22 mm,较其他组合降低约30%,且靶板内能吸收率最高。结论 通过对4种靶板组合的侵彻性能系统分析,确定CF/PEEK-CFRP组合为最优防护方案,达到了预期研究目的,为高速破片防护结构的工程应用提供了指导。
Abstract
The work aims to investigate the penetration resistance of different resin-matrix composite targets against high-velocity fragments, identify the optimal combination for penetration resistance, and provide a theoretical basis for the structural selection and optimization of protective materials. A finite element model of high-velocity fragment penetration was established using LS-DYNA software. Numerical simulation methods were employed to conduct the analysis, with carbon fiber-reinforced epoxy composite (CFRP), carbon fiber-reinforced polyetheretherketone composites (CF/PEEK), ultra-high molecular weight polyethylene-reinforced epoxy composites (UHMWPE/EP), and aramid-reinforced epoxy composites (AF/EP). Four composite target combinations were designed: CF/PEEK as the impact-facing surface paired with CFRP, UHMWPE/EP, AF/EP; and another with CFRP as the impact-facing surface combined with CF/PEEK. Penetration simulations were conducted for a 1.1 g cylindrical wedge-shaped fragment at an impact velocity of 2 000 m/s. The fragment damage behavior was described using the Johnson-Cook failure criterion, while the impact damage characteristics of the four resin-based composites were evaluated using the Chang-Chang failure criterion. Simulation results indicated that the target plate with CF/PEEK as the impact-facing surface and CFRP as the back surface exhibited the best penetration resistance. Under this configuration, the fragment kinetic energy was reduced to 0 J within 12 μs, the maximum deformation of the back surface was only 2.22 mm, approximately 30% lower than other configurations, and the target plate achieved the highest internal energy absorption rate. Through a systematic analysis of the penetration resistance of the four target plate combinations, the CF/PEEK-CFRP configuration is identified as the optimal protection scheme, achieving the intended research objectives and providing guidance for the engineering application of high-speed fragment protection structures.
