Abstract

This paper investigates the dynamic response and damage mechanisms of carbon fiber composite honeycomb sandwich structures subjected to high-velocity impacts by spherical projectiles. Experiments were conducted with impact velocities ranging from approximately 50 to 130 m/s, and the ballistic limit velocities of the structures were determined. The failure modes under varying impact velocities were analyzed. A realistic and accurate finite element analysis (FEA) model was developed to simulate the projectile penetration process and evaluate the energy absorption of each component of the sandwich structure. Numerical simulations were further employed to study the effects of various parameters, including impact location, core density, and face sheet thickness, on the impact resistance of the structure. The damage response of the sandwich structure under different impact angles was analyzed. Finally, the in-plane compressive failure mode of honeycomb sandwich structures after high-velocity impact damage and the residual failure load were investigated.

碳纤维蜂窝夹层结构高速冲击性能的实验与数值研究

研究了碳纤维复合材料蜂窝夹层结构在球形弹丸高速冲击作用下的动力响应及损伤机理。在50 ~ 130 m/s的冲击速度范围内进行了试验，确定了结构的弹道极限速度。分析了不同冲击速度下的失效模式。建立了真实准确的有限元分析模型，模拟弹丸侵彻过程，并对夹层结构各构件的能量吸收进行评估。通过数值模拟进一步研究了冲击位置、芯密度、面板厚度等参数对结构抗冲击性能的影响。分析了不同冲击角度下夹层结构的损伤响应。最后，研究了蜂窝夹层结构在高速冲击损伤后的面内压缩破坏模式和残余破坏载荷。

期刊介绍： The International Journal of Impact Engineering, established in 1983 publishes original research findings related to the response of structures, components and materials subjected to impact, blast and high-rate loading. Areas relevant to the journal encompass the following general topics and those associated with them: -Behaviour and failure of structures and materials under impact and blast loading -Systems for protection and absorption of impact and blast loading -Terminal ballistics -Dynamic behaviour and failure of materials including plasticity and fracture -Stress waves -Structural crashworthiness -High-rate mechanical and forming processes -Impact, blast and high-rate loading/measurement techniques and their applications
