Description
Technical Field
The utility model relates to a shellproof piece production field of boron carbide especially relates to a shellproof picture peg of boron carbide base.
Background
Boron carbide (boron carbide), also known as black diamond, has the formula B4C and is typically a grey black powder. Is one of the three most known hardest materials (the other two being diamond, cubic phase boron nitride), used in tank armors, armor and many industrial applications.
The existing boron carbide-based bulletproof effect cannot meet the requirement of high bulletproof level, the surface layer of the existing bulletproof flashboard is easy to break by bullets, the bulletproof is mainly carried out by a bulletproof steel plate in the middle of the bulletproof flashboard, the damage degree is large, the impact force on a human body is large, and the bulletproof level is low.
Disclosure of Invention
An object of the utility model is to overcome the problem that exists among the prior art, and provide a shellproof picture peg of boron carbide base, this shellproof piece novel structure, reasonable in design, shellproof rank is high, shellproof effectual, and the practicality is strong.
The technical scheme of the utility model is realized like this: the utility model provides a boron carbide base shellproof picture peg, includes shellproof picture peg, the middle part of shellproof picture peg is provided with shellproof steel sheet, shellproof steel sheet's front has set gradually high density polyethylene layer I, carbon fiber cloth layer I, boron carbide ceramic layer I, carbon fiber cloth layer II, glass steel layer, aramid fiber layer, boron carbide ceramic layer II and carbon fiber cloth layer III from inside to outside, shellproof steel sheet's the back has set gradually high density polyethylene layer II, carbon fiber cloth layer IV, boron carbide ceramic layer III from inside to outside.
Preferably, the thickness of the bulletproof steel plate accounts for 1/6 of the total thickness of the bulletproof flashboard.
Preferably, the thickness of the boron carbide ceramic layer is larger than that of the glass fiber reinforced plastic layer and the aramid fiber layer.
Preferably, the carbon fiber cloth layer III is arranged on the outermost layer of the front face of the bulletproof inserting plate, and meanwhile, the carbon fiber cloth layer III can cover the side wall of the bulletproof inserting plate.
The utility model discloses following beneficial effect has: the utility model discloses a shellproof picture peg of boron carbide base, this shellproof picture peg novel structure, reasonable in design, shellproof rank is higher, and shellproof effect is better, and the top layer of shellproof picture peg is provided with carbon fiber cloth layer and boron carbide ceramic layer, and protecting against shock ability is stronger to have stronger high temperature resistance, the practicality is strong.
Drawings
FIG. 1 is a schematic side view of an embodiment.
In the figure: 1-bulletproof inserting plate, 2-bulletproof steel plate, 3-high-density polyethylene layer I, 4-carbon fiber cloth layer I, 5-boron carbide ceramic layer I, 6-carbon fiber cloth layer II, 7-glass steel layer, 8-aramid fiber layer, 9-boron carbide ceramic layer II, 10-carbon fiber cloth layer III, 11-high-density polyethylene layer II, 12-carbon fiber cloth layer IV and 13-boron carbide ceramic layer III.
Detailed Description
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example (b): a boron carbide-based bulletproof inserting plate is shown in figure 1 and comprises a bulletproof inserting plate 1, wherein a bulletproof steel plate 2 is arranged in the middle of the bulletproof inserting plate 1, and the thickness of the bulletproof steel plate 2 accounts for 1/6 of the total thickness of the bulletproof inserting plate 1, so that a good bulletproof effect is achieved. The front face of the bulletproof steel plate 2 is sequentially provided with a high-density polyethylene layer I3, a carbon fiber cloth layer I4, a boron carbide ceramic layer I5, a carbon fiber cloth layer II 6, a glass fiber reinforced plastic layer 7, an aramid fiber layer 8, a boron carbide ceramic layer II 9 and a carbon fiber cloth layer III 10 from inside to outside, and the back face of the bulletproof steel plate 2 is sequentially provided with a high-density polyethylene layer II 11, a carbon fiber cloth layer IV 12 and a boron carbide ceramic layer III 13 from inside to outside. The thickness of the boron carbide ceramic layer is larger than that of the glass fiber reinforced plastic layer 7 and the aramid fiber layer 8. The carbon fiber cloth layer III 10 is arranged on the outermost layer of the front surface of the bulletproof inserting plate 1, and meanwhile, the carbon fiber cloth layer III 10 can cover the side wall of the bulletproof inserting plate 1. High density polyethylene layer intensity is higher, plays better shellproof effect, and carbon fiber cloth layer high temperature resistance can be better, and is softer, plays better shock resistance, and carbon fiber cloth layer III 10 sets up outwardly, and convenient the change increases the comfort level. The boron carbide ceramic layer has higher hardness and better bulletproof effect. The bulletproof flashboard 1 adopts a composite structure of an organic layer and an inorganic layer, and has better performance and better practicability.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
