The index of the puncture performance of transparent protective material is: the puncture that can bear 147J kinetic energy, and after puncture, material does not have by force the Durchgangshohle being greater than 6mm or occurring breaking outside the radius 20mm of force being subject to. Embodiment 1-3 and comparative example can reach puncture requirement, but the crackle that the matrix material of the high nitrogen woven wire of embodiment and polycarbonate occurs is less, and puncture performance is better. The resistance to ability of beating of hitting refers to that protective material can bear and beats hitting of trier and beat, and hitting milgraining speed is 18m/s �� 0.3m/s, and hit energy is 342J �� 13J, and hit beat after material should be broken or occur that length is greater than the crackle of 50mm. Embodiment 1 is resistance to hits the ability of beating preferably, and the resistance to ability of beating of hitting of embodiment 1-3 is all better than comparative example. Therefore, according to upper table, the integrated protection performance of embodiment 1-3 is more outstanding than the barrier propterty of comparative example.
