High velocity ballistic impact deformation behaviour of Titanium/GFRP Fiber Metal Laminates (FML) has been explored. Both single and multiple projectiles impact conditions were considered. Ti/GFRP FML targets were fabricated with addition of 5% and 10% weight percentage of boron carbide (B₄C) particles. Mechanical properties of Ti/GFRP FML targets were determined as per ASTM standards. High velocity ballistic experiments were conducted using Armour Piercing Projectile (APP) of diameter 7.62 mm and velocity ranging between 350 and 450 m/s. Depth of penetration of the projectile into the target was measured. The deformation behaviour of Ti/GFRP targets with and without the presence of ceramic powder (B4C) was investigated. “Ductile hole growth” failure mode was observed for pure GFRP target when subjected to single projectile impact whereas “plugging” failure mode was noted for Ti/GFRP targets. The presence of B₄C (5% by weight) particles has significantly improved the ballistic resistance of the Ti/GFRP FML target by offering frictional resistance to the projectile penetration. Further addition (10% by weight) of B₄C has reduced the ballistic performance due to agglomeration. None of the targets showed ‘brittle cracking’ or ‘fragmentation’ failures. When compared to the published results of Aluminium (Al 1100/GFRP and Al 6061/GFRP) FMLs, Ti/GFRP FML showed lesser DoP which increases its potential application to aerospace industry.

已经探索了钛/GFRP 纤维金属层压板 (FML) 的高速弹道冲击变形行为。考虑了单弹和多弹的撞击条件。Ti/GFRP FML 靶材是通过添加 5% 和 10% 重量百分比的碳化硼（B ₄C) 粒子。Ti/GFRP FML 靶材的机械性能根据 ASTM 标准确定。使用直径为 7.62 毫米、速度范围在 350 至 450 m/s 之间的穿甲弹 (APP) 进行高速弹道实验。测量射弹进入目标的深度。研究了存在和不存在陶瓷粉末 (B4C) 时 Ti/GFRP 靶材的变形行为。纯 GFRP 靶材在受到单弹冲击时观察到“延性孔生长”失效模式，而 Ti/GFRP 靶材则出现“堵塞”失效模式。B _4的存在C（5% 重量）颗粒通过为弹丸穿透提供摩擦阻力，显着提高了 Ti/GFRP FML 靶材的抗弹道性。_{B 4} C的进一步添加（10% 重量）由于附聚而降低了防弹性能。没有一个靶材出现“脆裂”或“碎裂”故障。与已发表的铝（Al 1100/GFRP 和 Al 6061/GFRP）FML 的结果相比，Ti/GFRP FML 的 DoP 较低，这增加了其在航空航天工业中的潜在应用。
