Research on ballistic resistance of ceramics composite armor with enhanced dwell effect
Lightweight reinforcement is the eternal pursuit of protective armor,and innovative structural design is an important means to achieve armor lightweight reinforcement.Based on the protective mechanism of the dwell effect of ceramic,this study designed the structure of the filled ceramic to enhance the dwell effect,effectively improving the lightweight reinforcement of the protective armor.This study also explored the influence of the structural parameters on the protection performance of new types of protective armor.The results demonstrated that the ballistic resistance mechanism of the new composite armor exhibited a sequential coupling of dwell effect and thickness effect.When the cone angle was 60°,the dwell effect of the new protective armor was the greatest,and it further increased with the increase of the height of the cone angle layer.Compared to the traditional ceramic composite armor,the weight of the new protective armor was reduced by 16.7％under the premise of equivalent kinetic energy dissipation rate and residual velocity of the projectile.
