Abstract

Abstract: The influence of ceramic panel on anti-penetration performance of Kevlar composite laminates during the penetration of high-speed projectile into Kevlar composite laminates is studied. The anti-penetration performances of 8 mm Kevlar composite laminates, 16 mm Kevlar composite laminates, 3 mm SiC ceramic + 8 mm Kevlar composite laminates, and 3 mm Al₂O₃ ceramic + 8 mm Kevlar composite laminates under high-speed penetration with 13.5 g FSP are experimentally investigated. The Deformation modes of projectile and Kevlar laminates with and without ceramic plate and the average absorbed energy per unit area density are analyzed. The results show that the projectile occurs large deformation and is accompanied by a quality abrasion when penetrating the target with front ceramic plate. The front ceramic plate reduces the shear damage degree of Kevlar laminates, and increases the tensile deformation and inter-layer delamination. Compared with pure Kevlar composite laminates, the front ceramic structure has a stronger anti-penetration ability at higher projectile speed. Key
