The invention relates to the technical field of bulletproof inserts, in particular to a composite bulletproof insert and a preparation method thereof, comprising a steel plate and an outer layer, the outer layer is arranged on the outer surface of the steel plate, and the top of the steel plate is connected with a mixed fiber layer , the bottom of the steel plate is connected with silicon carbide ceramics, the silicon carbide ceramics and the mixed fiber layer are connected with high-performance fibers on the side away from the steel plate, and the mixed fiber layer adopts one or both of carbon fiber and basalt fiber and UHMWPE fiber The high-performance fibers are specifically one or more of ultra-high molecular weight polyethylene fibers, aramid fibers, and PBO fibers. The composite bulletproof insert and the preparation method thereof can improve the protective performance of the bulletproof insert, and at the same time bring a better wearing experience and reduce the consumption of physical strength, while retaining the high protection function of the bulletproof insert, avoiding the The weight of the bulletproof board is relatively large, and it loses its mobility and flexibility. |
