The following study investigates the high-velocity impact performance of a ceramic-dyneema armor plate consisting of alumina with dyneema fiber. The target was to achieve a lightweight structure conforming to armor standards. Different thickness combinations of alumina/Dyneema targets were studied. Energy absorption criteria were used for investigating the impact performance of the target. Finite element analysis was performed using ANSYS/LS-DYNA®. A cylindrical projectile with an ogive nose of 10.9 mm in diameter and 52 mm in length was used. Projectile impact velocities were in the range of 500–887 m/s. First, the model was verified by comparing it with the existing experimental studies. Subsequently, various thickness combinations of alumina with a different number of layers of Dyneema were studied numerically to determine the effective thickness combination of the whole target. The initial kinetic energy of the target dissipated into the ceramic fracture and remained in the composite plate’s deformation. The study’s deciding factors were the projectile erosion and the target's energy absorption. The ceramic plate thickness majorly impacted the projectile erosion.
