Abstract

Fibre reinforced polymer composites have been established as potential materials for making body armours. The present work depicts estimation of ballistic resistance of multilayer ceramic backed fibre reinforced composite target through 3D numerical simulation using Ansys/Autodyn software. The present numerical and material models have been validated against the results available in the literature. After that, the velocity–time history of the projectile is examined for impact velocities ranging between 330 to 1200 m/s. Here, the study has been focused on predicting the progressive damage and failure modes of the ceramic-composites target plate under impact. Also, the variation in residual velocities, time of penetration/perforation with different incident velocities, damage pattern in the deformable projectile and the kinetic energy of the impactor is studied. Finally, the trend of variation of ballistic limit velocity with different masses and diameter of the impactor has also been investigated.
