Abstract

The impact-resistant antler-imitated bulletproof plugboard comprises a protective layer, a bulletproof layer and a buffer layer, and the bulletproof layer comprises a plurality of composite structure layers and bonding layers which are distributed at intervals; the composite structure layer is composed of two materials with different hardness and comprises a supporting rib plate and a composite structure unit, the composite structure unit comprises a transition area and a hardness and softness combination area, and the hardness and softness combination area comprises a plurality of soft thin sheets which are different in size and are distributed in a linear gradient mode, bridging grooves connected with the soft thin sheets and a hard base body. The bulletproof flashboard is beneficial to improving stress field distribution near a bullet impact point, effectively inhibiting crack initiation, guiding cracks to deflect, avoiding catastrophic failure modes in a traditional bulletproof flashboard, and increasing strain energy and fracture energy, so that the bulletproof performance of the bulletproof flashboard is greatly improved.

Description

technical field [0001] The invention belongs to the field of bulletproof technology, and more specifically relates to an impact-resistant imitation antler bulletproof board. Background technique [0002] In the field of national defense and military industry, high-performance body armor can effectively improve the combat capability of individual soldiers. On the battlefield, in order to resist high-level bullet threats, it is often necessary to add bulletproof inserts to body armor. The existing bulletproof board is composited with hard ceramics and fiberboards, wherein bulletproof fibers are used as the basis, and the core component is bulletproof ceramics. When a bullet hits the bulletproof plate, the bullet first hits the uppermost ceramic layer of the bulletproof plate, and the ceramic breaks and absorbs most of the kinetic energy of the bullet. When the bullet hits the fiber layer, the fiber layer consumes the kinetic energy of the bullet by stretching, and wraps the ...
