Embodiment Construction

[0025] see Figure 1 to Figure 4 As shown, a shield-shaped tail-type bionic direction-changing bulletproof board includes a shield-shaped tail-shaped surface layer 1, a bionic direction-changing layer 2, a middle energy-absorbing layer 3 and an inner layer 4, a shield-shaped tail-shaped surface layer 1, a bionic variable The orientation layer 2, the middle energy-absorbing layer 3 and the inner layer 4 are pressed and formed by autoclave molding; In the pressure tank, 360° isostatic pressing is used to avoid the slippage of the filling material and ensure the uniformity of the anti-ballistic performance;

[0026] The surface layer 1 of the peltate telson is to print alumina ceramics into two shield-like telomere symmetrical splicing structures through the laser selective sintering technology in 3D printing technology, and the pelvis-like telomere has a keel-like protrusion, and The spacing of the ridges has a certain ratio, and the peltate telson structure is a known structur...

Abstract

A shield-shaped tail section type bionic turning bulletproof flashboard comprises a shield-shaped tail section surface layer, a bionic turning layer, a middle energy absorption layer and an inner layer, and the shield-shaped tail section surface layer, the bionic turning layer, the middle energy absorption layer and the inner layer are formed in a pressing manner through an autoclave forming method. According to the shield-shaped tail section surface layer, aluminum oxide ceramic is printed into two shield-shaped tail section symmetric splicing structures through the selective laser sinteringtechnology in the 3D printing technology, the side, making contact with the middle energy absorption layer, of the bionic turning layer is of a corrugated structure, and the middle energy absorption layer is an ultra-high molecular weight polyethylene fiberboard. The inner layer is Kevlar woven fabric, and back protrusion inhibition is achieved. According to the shield-shaped tail section type bionic turning bulletproof flashboard, a chela bar structure and a shield-shaped tail section structure of mantis shrimps are used for reference, keel-shaped bulges of the shield-shaped tail section arebent inwards to absorb a large amount of energy when the surface layer of the shield-shaped tail section collides with shots, meanwhile, the bionic turning layer plays a role in changing the directionof the shots and reducing the impact kinetic energy, and the penetration resistance of the bulletproof flashboard is greatly improved.

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 insert. Background technique [0002] As a kind of protective equipment, the bulletproof plate provides an important guarantee for the life safety of individual soldiers. In order to improve the protection level of bulletproof vests, the application of bulletproof inserts is more and more extensive. The rapid development of weapons and equipment has gradually increased the threat to the life safety of individual soldiers. In order to ensure the safety of individual soldiers and improve the flexibility of individual combat, it is necessary to develop light-weight and high-efficiency bulletproof equipment. [0003] The upwardly curled shield-like structure of the mantis shrimp's tail is called the telson, which protects it from the powerful "elbows" of competitors. [0004] The tiny crustacean manti...
