Research on Theoretical Model of Ceramic/PE Composite Protection for Projectile

Abstract

Abstract In order to predict the ballistic limit of ceramic/ UHMWPE composite protection, a theoretical model of ceramic/UHMWPE composite protection for projectile was established based on A-T model and fiber energy dissipation model. In the ballistic impact process, the fragments will experience ceramic dwell, ceramic fragmentation and fiber layer energy dissipation. The theoretical model obtained is compared with the experimental and simulation results. The results show that the residual velocity obtained by the theoretical model is in good agreement with the experimental and simulation results, and it can be applied to ceramic/UHMWPE composite protection of projectile penetration to a certain extent.
