Experimental Study on Ballistic Resistance Property of 3D Kevlar Woven Composites

By a series of ballistic experiments of three Dimensional orthogonal Kevlar Woven(3DKW) composite targets,the ballistic resistance properties of 3DKW targets with different thickness were investigated;the value of ballistic limit V50 was directly deduced by Trans-critical velocity zone method.Based on experimental data of whole penetration-zone,the relation of consumption energy of 3DKW target penetrated by a standard steel ball E and plane-density of target Fp was summarized,and the value of consumption energy factor per plane-density λ was obtained,moreover the value of ballistic limits V50 was forecasted.Furthermore,an improved engineering energy analysis model was presented.Based on the modified model and the experimental data,the ballistic limits V50 of 3DKW target were obtained.All forecasted values of V50 are in good agreement with the experimental results.
