Here, the base layer member 10b is overlapped and positioned on the seating portion B in the center of the polyethylene layer member 20b. Accordingly, the seating surface of the base layer member 10b is covered by the polyethylene layer member 20b.

Subsequently, the respective circular arc portions 10b1 to 10b8 of the base layer member 10b are covered with the circular arc cover portions 20b1 to 20b8 of the polyethylene layer member 20b, thereby surrounding the base layer member 10b.

Meanwhile, in consideration of the thickness of the hexagonal base layer member 10c, an area corresponding to the thickness may be additionally formed between the seating portion C and the partition cover portions 20c1 to 20c6.

Here, the base layer member 20c is overlapped and positioned on the seating portion C in the center of the polyethylene layer member 20c.

Subsequently, the respective triangular sections 10c1 to 10c6 of the base layer member 10c are wound around each of the compartment cover portions 20c1 to 20c6 of the polyethylene layer member 20c to cover the base layer member 10c.

Meanwhile, similarly to the polyethylene layer member 20b according to the embodiment shown in FIG. 5, the polyethylene layer member 20c according to the embodiment shown in FIG. 6 is wound around the base layer member 10b a plurality of times. As a result, the base layer member 10c can be configured to be covered with a plurality of polyethylene layers. At this time, similar to the embodiment shown in (f) of FIG. 5, in consideration of the tolerance, the size of the polyethylene layer member located below is formed to be larger than the polyethylene layer member located above.

[Production method of other protective panel]

In addition, the protective panel 100 may be manufactured in an elliptical or half moon shape, and in this case, the surface of the protective panel is wound around a plurality of times using the polyethylene layer member 20a1 to protect the plurality of polyethylene layers. Panels can be produced.

On the other hand, the carbon fiber layer and the aramid fiber layer can be further laminated on the plurality of polyethylene layers 20 of the protective panel produced by the protective panel manufacturing method.

As an example, in the embodiment according to FIGS. 4 to 6, the base layer 10a to 10c is bent eight times using eight polyethylene layer members 20a, 20b, and 20c, and then the carbon fiber layer By winding the member and the aramid fiber layer member sequentially, a protective panel having a composite layer laminated in the ratio of polyethylene fiber layer 8: carbon fiber layer 1: aramid fiber layer 1 in the order adjacent to the base layer can be produced.

The reason why the composite layer is formed as described above is that the polyethylene fibers have an advantage of having a strong tensile strength of about 2 times and a specific gravity of about 2/3 of the aramid fibers, but are relatively weak in heat. This is to prevent the strength of the polyethylene fiber may be weakened or deformed by frictional heat due to kinetic energy during collision with the warhead. That is, as described above, when the carbon fiber layer becomes the outermost layer that initially collides with the warhead of the protective panel 100, and a structure in which the aramid fiber layer is supported between the carbon fiber layer and the polyethylene layer is adopted, deterioration and deformation of the polyethylene layer Since this is prevented, the warhead progression blocking effect can be further improved.

FIG. 7 illustrates a state in which the protection panel assembly 200 is manufactured by connecting the unit protection panel 100 in a straight direction (for example, in a horizontal direction) according to an embodiment of the present invention.

Fabrication of the protective panel assembly 200, a fabric formed by weaving high-density polyethylene fibers in a variety of forms, or a high density that can be formed by unidirectional alignment fabric (UD) made by arranging the fibers in one direction and bonding using resin It is carried out using the polyethylene fabric member 30.

First, the polyethylene fabric member 30 having a predetermined horizontal length and vertical length is prepared. Considering that the protective panel is manufactured, for example, with a diameter of 50 mm, in consideration of the rod 31 of the upper end of the polyethylene fabric described below, the longitudinal length H of the polyethylene fabric member 30 is, for example, 100 mm or more. It can be set within the range of 150mm.

Subsequently, the original member 30 except for the bar portion 31 is folded in half in an upward direction along a horizontal fold line 30a indicated by a dotted line. As a result, an end portion of the lower fabric portion 32 overlaps with an end portion of the upper fabric portion 33, and a two-layer distal end portion of which the lower end is closed is formed. At this time, the vertical length (h1, h2) of the lower fabric portion 32 and the upper fabric portion 33 is the same, the vertical length of the distal end of the two layers is the same.

Subsequently, in consideration of the diameter of the protection panel, a plurality of encapsulation portions capable of accommodating the unit protection panel by sewing along a vertical sewing line 30b indicated by a single-dotted line separated horizontally by a predetermined distance, for example, 50 mm. Will generate (34).

Subsequently, by inserting the unit protection panel 100 into each of the encapsulation part 34, a protective panel assembly 200 according to an embodiment of the present invention is produced. As described above, when the protection panel assembly 200 is bent in the horizontal direction, the encapsulation portions 34 are bent to each other about the sewing line 30b.

Subsequently, by cutting along the cutting line 30c indicated by the double-dotted line between the sewing lines 30b, each connected sealing portion 34 is separated to improve the freedom of movement of each sealing portion 34. FIG. That is, when the protection panel assembly 200 is bent in a horizontal direction, the encapsulation portions 34 may be bent with respect to the sewing line 30b and rotate about the sewing portion 31. .

Here, the interval between the cutting lines 30c can be set to 50 mm or more in consideration of the diameter of the protective panel.

Meanwhile, the insertion of the unit protection panel 100 into each of the encapsulation portions 34 may be performed after the cutting step, and after the protection panel is inserted, the insertion portion may be sealed. In addition, the protection panels 100 according to the first to third embodiments may be inserted into the encapsulation portions 34. In addition, single-piece ceramic protective panels, CFRP protective panels, and GFRP protective panels produced in the square, circle, hexagon, ellipse, and half moon shapes can be inserted alone or in combination.

By inserting such a single ceramic protection panel, CFRP protection panel, GFRP protection panel alone or a combination thereof, in the protection panel assembly according to the present invention, the layer structure according to FIG. 3 can be implemented again.

In addition, in the embodiment of FIG. 7, the H portion may be folded in half, and the sewing portion 31 and the sealing portion 34 may be formed by sewing and cutting in a state where two layers of distal portions are formed.

FIG. 7A illustrates a state in which a fold line, a cutting line, and a sewing line are displayed on the high-density polyethylene fabric member 30, and FIG. 7B is a view of sewing the polyethylene fabric member 30, 2 is a view illustrating a state in which the protection panel assembly 200 is manufactured, and a circular protection panel 100 is inserted into each encapsulation portion 34.

[Production method of protective panel laminate]

On the other hand, the protective panel assembly 200 manufactured as described above may be combined as a plurality of protective panel assembly 300 for the production of body armor.

FIG. 8 illustrates that the unit protection panel assembly 200 is partially overlapped and stacked in a straight direction (for example, vertical direction) on a fabric member 301 for manufacturing a body armor according to an embodiment of the present invention. The state which produced the panel laminated body 300 is shown.

The protective panel laminate 300 may be formed of a woven fabric formed by weaving high density polyethylene fibers in various forms, or a unidirectional oriented fabric (UD) made by arranging the fibers in one direction and bonding them using a resin. It is performed using a high density polyethylene fabric member 301. The fabric member 301 may be the same component as the high density polyethylene fabric member 30.

First, the polyethylene fabric member 301 having a predetermined longitudinal length and a horizontal length is prepared.

Subsequently, the unit protection panel assembly 200 of one row (odd rows) is sewn by sewing the unit protection panel assembly 200 to one surface (for example, the front surface) of the fabric member 301 along the sewing line 30d. 200 is attached to the distal end member 301 in the horizontal direction.

Subsequently, by sewing the other unit protection panel assembly 200 to the fabric member 301 along the sewing line 30d, two rows (even rows) of the unit protection panel assembly 200 are horizontally disposed in the fabric member. 301 is attached.

In this case, the two rows of even-numbered protective panel assemblies 200 may partially cover the one-row (odd rows) protective panel assemblies 200 so that the odd-numbered rows of protective panel assemblies 200 are attached. It is sewn on the upper side in the range within the length h2 from the position of 301.

Here, when the unit protection panel assembly 200 of even rows (eg, the second row) is stacked on the unit protection panel assembly 200 of the odd rows (eg, the first row), a cut line ( Separation lines 30e between the encapsulation portions 34 generated through the cutting process according to 30c) may be formed between the separation lines 30e1 of the unit protection panel assembly 200 of the odd rows (eg, the third row). The odd-numbered and even-numbered protective panel assemblies are sewn to the polyethylene fabric member 301 so that the even lines (for example, the second row) of the unit protection panel assembly 200 of the unit protection panel assembly 200 are positioned.

Meanwhile, the process of attaching the unit protection panel assembly 200 to the fabric member 301 is repeated a plurality of times. Preferably, the unit protection panel assembly 200 attached to the fabric member 301 is preferably attached in parallel to each other along the horizontal direction.

[Impact amount absorbing structure in protective panel laminate]

The protective panel laminated body produced as mentioned above is used as a raw material for body armor. On the other hand, when the protective panel laminate is in contact with the curved portion of the human body, the upper and lower sealing portion is shown in the form as shown in Fig. 9 (a).

That is, (a) of FIG. 9 is a diagram schematically showing the arrangement of each of the encapsulation portions 34 in a state in which the protective panel laminate is curved and viewed in the b direction of FIG. 8. When the sieve contacts the curved portion of the human body, the encapsulation portion 34a of the protective panel stack positioned above is kept horizontal, and the two encapsulation portions 34b positioned under the encapsulation portion 34a are One end is in contact with the encapsulation portion 34a, and the other end exhibits a buffer structure spaced apart from the encapsulation portion 34a. That is, the two sealing parts 34b located at the lower side show the buffer structure for supporting the sealing part 34a located at the front end.

As described above, the shock absorbing structure including the horizontal sealing portion 34a and two sealing portions 34b at which one end portion comes in contact with the rear surface of the sealing portion 34a and the other end portion is spaced apart is shown in FIG. 9. As shown in (b), when the warhead collides with the front face of the upper sealing part 34a, the sealing part 34a is retracted by the pressing force of the warhead, so that the lower sealing part 34b As it moves forward, the contact area between the upper and lower encapsulation portions is enlarged, so that the impact amount delivered to the first front encapsulation portion 34a is transferred to the two rear encapsulation portions, and the impact amount is alleviated and dispersed.

In addition, since the structure of FIG. 9A is continuously formed along the horizontal direction of the protective panel stack, the impact amount due to the cut is continuously dispersed through the adjacent sealing portions 34b 'and 34a'.

On the other hand, such a buffer structure, in the manufacture of the protective panel laminate, the even rows (e.g., between the even lines (e.g., the third row) between the dividing lines 30e1 of the unit protection panel assembly 200. For example, the odd-numbered and even-numbered protective panel assemblies may be formed in the polyethylene fabric member 301 so that the separation lines 30e2 of the unit protective panel assembly 200 of the second row may be positioned.

Therefore, the protective panel laminated body or body armor which employ | adopted the above-mentioned buffer structure easily loosens and distributes the impact amount of a warhead.
