A finite element model of conical projectiles impacting composite laminated plates had been established by using Abaqus software.The reliability of the model was verified by comparing with the existing literature.And the relationship between the residual velocity and the initial velocity of the conical projectile at different angles of incidence,the failure mode of the composite laminated plate and the rules of projectile ricochet were studied.The results show that when the projectile impacts the laminates at 90°and from the critical velocity is larger,the residual velocity of the projectile is linearly related to the initial velocity.Different initial velocities can lead to different damage areas of the laminate and different mechanisms of damage.The smaller the incident angle of the projectile,the thicker the laminate,the more prone to ricochet,and the influence of the angle of incidence and the number of laying layers on the ricochet is given.The study can provide a reference for the design and optimization of various protective equipment.
