Problems solved by technology

[0002] At present, high-performance fibers such as aramid fibers are used for bulletproof inserts on the ceramic surface for lateral restraint, which plays the role of crack arrest and anti-sputtering. However, this structure has the problem of poor restraint on the side of the ceramic, which easily causes ceramic cracks to spread to the edge, making it difficult to Guarantee the integrity of bulletproof ceramics, resulting in insufficient resistance to multiple bullets
[0003] The patent with the publication number CN110230952A proposes to constrain the entire circumference of the ceramic bulletproof panel by means of integral fiber winding, but since the ceramic plate is multi-curved, the winding effect of this method on the concave surface is not ideal
The patent of Publication No. CN110953933 A proposes to use seamless tubular fabric orthogonally nested to cover the ceramic plate in a seamless tubular shape, but it is convenient to cover the ceramic plate because the nest is larger than the ceramic plate, so this method covers The overlaid ceramic surface is prone to wrinkling

Abstract

The invention discloses a bulletproof flashboard with an edge covering structure and a manufacturing method thereof. The bulletproof flashboard comprises first woven cloth, a ceramic plate, second woven cloth and an ultra-high molecular weight polyethylene plate which are arranged in sequence, wherein the edge end face of the ceramic plate is covered with the edge part of the first woven cloth. According to the bulletproof flashboard with the edge covering structure, the edge end part of the ceramic plate is coated with the woven cloth, so that the surface and the end surface of the ceramic plate are coated with the continuous woven cloth, constraint force on the ceramic plate in the three-dimensional direction is formed, the mechanical strength of the ceramic plate is enhanced, the back bulge value of the bulletproof flashboard is effectively reduced, and the bullet resistance and the multi-bullet resistance of the bulletproof flashboard are improved.

Guarantee the integrity of bulletproof ceramics, resulting in insufficient ability to resist multiple bullets. [0003] The patent with the publication number CN110230952A proposes to constrain the entire circumference of the ceramic bulletproof panel by means of overall winding of fibers, but since the ceramic plate is multi-curved, the winding effect of this method on the concave surface is not ideal. The patent of Publication No. CN110953933 A proposes to use seamless tubular fabric orthogonally nested ...
