Multilayered bullet resistant member, preparation method and application thereof

A method of preparing a multilayered bullet resistant member, comprising the steps of:

• 1) preparing a metal-ceramic crack arrest reflecting layer:
• compounding a surface pretreated ceramic material preform by adopting a ceramic preform metal solution infiltration method to obtain the metal-ceramic crack arrest reflecting layer, wherein a content ratio of a metal to a ceramic is 1:1, a preform has a preheating temperature of 300° C.-500° C., a casting temperature of 700° C.-900° C., and a permeation pressure of 2 MPa-5 MPa;
• 2) preparing a fiber-elastomer composite energy absorbing layer:
• combining a high-performance fiber and an elastomer material by adopting an impregnation drying method or a foaming curing process, so as to obtain a fiber-elastomer composite material, and compounding the fiber-elastomer composite material with a matrix resin by adopting a vacuum assisted forming process to obtain the fiber-elastomer composite energy absorbing layer, wherein a curing temperature is 80° C.-150° C.;
• 3) preparing a two-dimensional fabric blunt trauma protective layer:
• respectively impregnating one or more high-performance fiber bundles and a high-performance plain woven fabric in the matrix resin, uniformly spreading the one or more high-performance fiber bundles and the high-performance plain woven fabric by using a compression roller, wherein the one or more high-performance fiber bundles are used for preparing a single UD sheet, and a content of the matrix resin is controlled to be 15-20 wt %;
• laying 20 layers of the single UD sheet in cross-ply at a preset mixing ratio by 0°/90° to obtain a first fabric layer, laying 4 to 6 layers of the high-performance plain woven fabric to obtain a second fabric layer, and bonding the first fabric layer and the second fabric layer together with a compounding machine and a flat plate thermocompressor to obtain the two-dimensional fabric blunt trauma protective layer, and pressing under 10 MPa-20 MPa for 4 h to 5 h at a curing temperature of 80° C. to 150° C.;
• and
• 4) bonding and compounding the metal-ceramic crack arrest reflecting layer, the fiber-elastomer composite energy absorbing layer and the two-dimensional fabric blunt trauma protective layer, so as to prepare the multilayered bullet resistant member.
