Abstract

A protective layered element consisting of outer and inner layers having a bend, where, in order to prevent a reserved effect on the protected object and increase ease of use, the inner layer is made of an elastic-plastic material, the strength of which is 1.6 times less than the strength of the outer layer.

Description

The utility model belongs to the defense industry, automotive industry, and the industry related to the manufacture of sports equipment, etc.

A known impact-resistant armor-protective layered element consisting of two outer layers of high-rigidity material and an inner layer of viscoelastic material, which has a bend with a deflection arrow within 10...15 thicknesses, and has a connection of the outer layers of high-rigidity material by on the opposite edges, staples made of plastic material, which during plastic deformation flows into edge holes made coaxially in the outer layers, on the inner side of the layered element, a shock-absorbing layer is attached, made of elastic foamed polymer material, the back surface of which corresponds to the surface of the object being protected. Shock-resistant armor protection element. Utility model patent Mo 147309. IPC

E41 5/02, 5/04, 5/0, Bul. Mo. 17 from 04/29/2021/. The disadvantage of this armor protection element is that it is inconvenient to use when preventing a reserved action on a convex object being protected, for example, a human body.

The basis of the useful model is the task of increasing the effectiveness of preventing a blocked action and ease of use due to additional energy costs for the deformation of the device elements on the part of the striker and the possibility of providing the inner layer with a convex shape close to the shape of the protected object.

The essence of the useful model is explained by figures 1, 2, C and 4, which show the general appearance and construction of the protective layered element, the process of its deformation under the impact of the load from the striker and its connection with another element for comprehensive protection.

Fig. 2 - cross section of the armor protection element consisting of the outer layer 1, inner layer 2, with bent ends 3, bend 4.

Fig. C - shows the process of deformation of the outer and inner layers when loaded with impactor 5. Arrows show the directions of movement of the inner and outer 2 layers, which have a bend within 10.

Fig. 4 - shows the connection of two protective layered elements with bent plates 6 for comprehensive protection of the object.

The protective layered element consists of the outer 1 and the inner 2, which have

From bending within 15 of their thicknesses and connected to each other. The inner layer is made of elastic-plastic material, the strength of which is 1.6 times less than the strength of the outer layer. The ends of the inner layer with a length of 10 of its thickness are bent at an angle of 60" to the vertical axis, which are tangent to the place of bending.

The inner surface of the inner layer rests on bent plates 4. Plates 4 with a convexity opposite to the object to be protected and connected to the surface of the inner layer, for example, by riveting with a similar protective layered element 5, located on the opposite side of the object, which is protected 6.

The bent ends C have an additional bend 7 with a length of at least six thicknesses of the inner layer 2. The bend angle corresponds to the tangent 8 to the inner surface of the outer layer. The ends of the latter are connected to the bending surface 7, for example, by riveting.

The protective layered element works as follows (Fig. 3), when the outer surface 9 of the outer layer collides with the impactor 1, it bends. When it is bent under the action of reactive moments, the ends C of the inner layer and plates 4 are bent in the direction opposite to the location of the protected object b. That is, the load on the protected object practically does not occur due to the movement of the inner layers in the opposite direction to the protected object 6. Also, the kinetic energy of the impactor is spent on bending the outer 1 and inner 2 layers, unfolding the tips 3, plates 4, moving the entire protective system.

Application of the proposed protective layered element practically eliminates the armored effect on the protected object. The use of similar structures in ammunition for sports competitions (hockey, football, rugby, martial arts, etc.) prevents injuries to athletes. In addition, the use of the device as facing elements of armored vehicles prevents damage to structural elements and the crew as a result of being hit by bullets, shells and debris.
