Test and Simulation of SiC Ceramic/UHMWPE Fiber Composite Structure Against 12.7mm Armor Piercing Incendiary Projectile

doi:10.12382/bgxb.2021.0604

Abstract

Abstract: The composite structure composed of SiC ceramic board and ultra-high molecular weight polyethylene (UHMWPE) fiberboard is studied. In order to understand the influence of component thickness on the penetration resistance of the anti-ballistic body， the test of 12.7 mm armor-piercing incendiary projectile penetrating into the composite structure was made to obtain the penetration effect at different impact velocities. A finite element model of a projectile penetrating into the composite structure is established， and the reliability of the model is verified by tests. The proposed finite element model is used to simulate the composite structure of 12.7 mm armor piercing incendiary projectile penetrating into different thickness components， and the failure mechanism and anti-ballistic performance of composite structure subjected to projectile penetration are analyzed. The results show that the proposed finite element model can be used to reliably calculate the effect of 12.7 mm armor piercing incendiary projectile penetrating into the composite structure. The ballistic performance of the composite structure increases linearly with the increase in the component thickness， and the influence of SiC ceramics on the ballistic performance is greater than that of UHMWPE fiberboard. With the increase in the thickness ratio of SiC ceramic and UHMWPE fiberboard， the ballistic performance of composite structure first increases and then decreases. When the thickness ratio is between 0.2 and 0.4， the ballistic performance of composite structure is the best.
