Shield-shaped tail section type bionic turning bulletproof helmet

Abstract

A shield-shaped tail section type bionic turning bulletproof helmet sequentially comprises four shield-shaped tail section surface layers, a bionic turning layer and an internal buffer layer from theouter surface layer to the inner surface layer of the helmet, and the four shield-shaped tail section surface layers stably transit to the bullet-facing surface of the periphery of the bulletproof helmet. The shield-shaped tail section surface layers, the bionic turning layer and the internal buffer layer are formed in a 360-degree isostatic pressing mode through an autoclave forming method, and the shield-shaped tail section surface layers are each of a structure that aluminum oxide ceramic is printed into two shield-shaped tail sections to be symmetrically spliced through a selective laser sintering technology in the 3D printing technology. A stick-like structure and a shield-like tail-segment structure of odontodactylus scyllarus are used for reference. The shield-shaped tail section surface layers collide with a projectile, keel-shaped protrusions of a shield-shaped tail section are bent inwards to absorb a large amount of energy, meanwhile, the functions of changing the directionof the projectile and reducing impact kinetic energy are achieved, the penetration resistance of a bulletproof inserting plate is greatly improved, the overall rigidity of a multi-layer structure is large, and when impacted by the projectile, the bulletproof inserting plate is small in overall deformation, light in weight and convenient to carry and wear, and increases comfort.

Description

technical field [0001] The invention relates to the technical field of bulletproof equipment, in particular to a shield-shaped tail section bionic direction-changing bulletproof helmet. Background technique [0002] Bulletproof helmet is an important equipment for personal combat head safety protection. At present, traditional bulletproof helmets are made of UHMWPE fiber composite material or aramid fiber composite material by hot pressing. There are many problems in the characteristics, such as the high temperature creep problem of UHMWPE fiber composite material is serious, the overall deformation of the projectile penetration protection process is relatively large; the anti-ultraviolet aging problem of aramid fiber composite material is serious, which affects the service life and safety of the overall helmet . In order to improve these problems, researchers tried to use carbon fiber and the above fibers to form a laminated bulletproof helmet to solve the problem of rigid...
