The protective material adopts a multi-type flexible material composite structure as an outer protective layer, and the composite hard protective material with the ceramic layer 5 and the titanium alloy plate 6 arranged on the inner side has extremely strong protective performance. The design idea of the invention is to utilize the Kevlar fiber layer 1 at the outermost layer to absorb part of kinetic energy of bullets and buffer the impact of steel core bullets. And the carbon nano tube fiber layer 3 soaked in the STF is used as a main bulletproof soft layer for effectively resisting the injection kinetic energy of the steel core bullet.

The ceramic layer 5 and the titanium alloy plate 6 are used as final protective layers to provide hard protection, and provide enough hardness and strength for the low-kinetic energy steel core bullet buffered by the soft material to resist the penetration of the bullet. The above materials are organically combined, and the organic matching of various material characteristics and the configuration of energy absorption sequence enable the bulletproof material of the invention to effectively protect the penetration of steel core rifle bullets under the thickness of 8 cm.
