The influence of interlayer strength of PE UD bulletproof board on V50
The interlayer strength of PE UD bulletproof board has a significant impact on its own bulletproof ability.This paper studied the relationship between interlayer strength and bulletproof performance of PE UD fabric laminates by adjusting the interlayer strength of PE UD bulletproof board.Within a certain range,as the interlayer strength of PE UD fabric laminates increases,the bulletproof performance first increases and then decreases.There is an optimal bulletproof performance,and for defending against 1.1 g fragmentation bullets,the optimal interlayer strength is 3.0 kN/m;for the 7.62 mm×39 mm mild steel core(MSC),the optimal interlayer strength is 2.5 kN/m.As the interlayer strength of PE UD fabric laminates increases,the average backface deformation shows a significant downward trend.
