B4C陶瓷/UHMWPE纤维复合结构抗7.62mm穿燃弹侵彻性能
The Performance of B4C Ceramic/UHMWPE Fiber Composite Structure against Penetration by 7.62 mm Armor-piercing Incendiary Projectiles
摘要
Abstract
To support the structural design of ceramic composite inserts,a finite element computational model for projectile pene-tration into composite structures was established and its reliability was validated through experiments.Using this model,the pro-cess of a 7.62 mm armor-piercing incendiary projectile penetrating a composite structure was simulated.The anti-penetration characteristics,such as target plate failure and the retention effects during projectile penetration,were analyzed.The influence of bullet velocity,ceramic thickness and fiber thickness on the anti-penetration performance of the composite structure was stud-ied.The study shows that there is a synergistic effect between ceramics and fibers during projectile penetration.The retention ef-fect significantly impacts the anti-penetration performance of the ceramics-the lower the bullet velocity,the longer the retention time,and the higher the percentage of bullet kinetic energy dissipation.At a bullet velocity of 500 m·s-1,the kinetic energy dissi-pation during the retention period is 68.4%.The specific energy absorption of the composite structure increases with the increase of material thickness,but the penetrating specific energy absorption of the composite structure initially rises and then decreases as material thickness icreases.关键词
