Description

방탄판재의 제조방법 및 파편방탄복{METHOD OF PRODUCING BULLETPROOF PANEL AND A BULLETPROOF JACKET MADE THEREOF}METHODS OF PRODUCING BULLETPROOF PANEL AND A BULLETPROOF JACKET MADE THEREOF

본 발명은 방탄판재의 제조방법 및 파편방탄복에 관한 것이다.The present invention relates to a method for producing a bulletproof board member and fragment body armor.

본 발명을 더욱 구체적으로 설명하면 밀도가 0.97g/㎤인 폴리에틸렌 부직포 및 일방향배열(Unidirectional, UD)프리프레그를 고밀도로 적층, 일정의 압력과 125℃-135℃ 의 열을 가해 압축성형하여 보가 경량이며 일정각을 갖는 방탄성능이 우수한 방탄판재의 제조방법에 관한 것이다.In more detail, the present invention is more specifically laminated to a polyethylene nonwoven fabric having a density of 0.97 g / cm 3 and a unidirectional (UD) prepreg at high density, and compression-molded by applying a constant pressure and heat of 125 ° C-135 ° C. And it relates to a method for producing a bulletproof plate material having excellent anti-ballistic performance having a constant angle.

일반적으로 방탄판재는 군사적 목적을 위하여 장비 및 인명을 보호하기 위한 장갑으로 최근에는 기동성, 이동성, 방호성능을 요구하는 기동장비의 특성으로 경량화를 위하여 가벼우면서도 방호성능이 우수한 방탄판재를 요구하는 것이다.In general, bulletproof plate is a glove for protecting equipment and life for military purpose. Recently, it is a characteristic of mobile equipment that requires mobility, mobility, and protection performance.

이러한 요구를 충족시키기 위하여, 방탄판재는 여려가지의 원료 즉 기능성 섬유를 사용하는데 그 중의 한가지는 케블러섬유를 여러겹 봉재한 방탄복에 적용하여 사용하나 이러한 방탄복은 직격탄으로부터는 인명을 보호할 수 없는 문제점이 있고, 또한 폴리아미드섬유는 섬유자체의 높은 밀도(1014g/㎤)로 인해 중량이 무겁고 착용감이 뼛뼛하며 수분에 의해 방탄재의 성능이 저하되는 단점이 있어, 이를 적층하여 구성된 방탄판재 역시 직격탄으로부터는 인명을 보호할 수 없는 문제점이 있는 것이다. 따라서 직격탄으로 부터 인명을 보호하기 위하여서는 방탄판재의 두께가 두껴야만 하고 따라서 방탄판재의 무게가 무거워지는 것이다 따라서 방호성능은 우수하나 이동성 및 기동성이 떨어지는 문제점이 있는 것이다.To meet these demands, bulletproof boards use several kinds of raw materials, or functional fibers, and one of them is applied to Kevlar fiber-sealed body armor, but such body armor cannot protect lives from direct bombardment. In addition, the polyamide fibers have a disadvantage that the weight of the fiber itself is heavy due to the high density (1014 g / cm 3), and the wearability is reduced, and the performance of the bulletproof material is degraded by moisture. There is a problem that cannot protect lives. Therefore, in order to protect human life from direct bombs, the thickness of the bulletproof board must be double, and thus the weight of the bulletproof board is heavy. Therefore, the protection performance is excellent, but mobility and mobility are inferior.

이에 본 발명은 이러한 문제점을 개선하게 위하여 폴리에텔렌 부직포 및 일방향배열 프리프레그를 구성하여 이를 고밀도 적층, 압축성형하여, 경량화하여 이동성, 기동성, 방탄성능이 우수하여 파편 및 직격탄으로부터 인명을 보호할 수 있는 방탄판재를 제조 하는 것이다.In order to solve this problem, the present invention constructs a polyetherene nonwoven fabric and a unidirectional array prepreg, and densely laminates and compresses it to reduce weight, thereby protecting life from debris and direct bombs due to its excellent mobility, maneuverability, and bulletproof performance. It is to manufacture bulletproof board.

본 발명은 밀도가 0.97g/㎤인 폴리에틸렌 부직포 및 일방향배열 프리프레그를 고밀도 적층, 일정압력과 일정량의 열을 가해 압축성형하여 폭 250㎜Ⅹ300㎜로 절단되어 구성된 방탄판재를 제조함이 그 목적이다.It is an object of the present invention to manufacture a bulletproof plate composed of a polyethylene nonwoven fabric having a density of 0.97 g / cm 3 and a unidirectional array prepreg, which is cut to a width of 250 mm to 300 mm by high-density lamination, compression molding by applying a constant pressure and a certain amount of heat. .

본 발명의 또 다른 목적은 내수성이 강한 고밀도 폴리에틸렌을 사용하여 방탄복의 무게를 경량화하고 착용감이 우수한 방탄복을 제공하는 것이다.Another object of the present invention is to use a high-density polyethylene strong in water resistance to reduce the weight of the body armor and to provide a body armor with excellent fit.

상기와같이 방탄판재(10)는 밀도가 밀도가 0.97g/㎤인 폴리에틸렌 부직포 및 일방향배열 프리프레그를 금형에 넣고 125℃-135℃ 에서 압출성형한 후 폭 250㎜Ⅹ길이300㎜로 절단한다. 상기 절단된 방탄판재는 사각 날카로운 부위는 가공한 후 방탄판재에 접착제를 사용하여 방수포(11)를 접착시켜 밀봉 시겨 구성된 것이다.As described above, the bulletproof plate 10 is placed in a mold with a polyethylene nonwoven fabric having a density of 0.97 g / cm 3 and a one-way array prepreg in a mold and extruded at 125 ° C.-135 ° C., and then cut into a width of 250 mm × length 300 mm. The cut bulletproof plate material is formed by sealing a rectangular sharp portion by sealing the waterproof cloth 11 by using an adhesive to the bulletproof plate material after processing.

상기 방탄판재는 파편방탄복(12)의 방탄판주머니에 삽입하면 파편탄과 직격탄을 동시에 방어할 수 있는 것이다.The bulletproof plate material is to be inserted into the bulletproof plate pocket of the fragment body armor 12 to simultaneously defend the fragmentation bombs and direct hit.

상기 방탄판재는 1예로 1겹의 밀도가 190g/㎠인 부직포를 7겹 적충한 방탄재를 삽입한 파편 방탄복의 방탄성능은 MIL-P-662(방탄복 탄도시형)에 따라 시험(시험탄 :MIL-P-46593의 Cal. 22의 2형)하였을 때 470 m/s 이상을 나타내었다. 1겹의 면밀도가 254g/㎠ 인 일방향 프리프레그를 65겹 압축성형한 길이폭 250㎜Ⅹ길이300㎜Ⅹ두께180㎜ 방탄판을 AK탄 7.62㎜로 시험 하였을 때 방탄성능이 730m/s 이상을 나타내었으며, 또한 방탄판재의 무게는 1.4kg미만인 것이다.In the case of the bulletproof board, the bulletproof performance of the fragmentary body armor in which the bulletproof material containing 7 layers of nonwoven fabric having a density of 190 g / cm2 in one layer is inserted is tested in accordance with MIL-P-662 (bullet-proof ballistic type) (test bullet: MIL) -P-46593 Cal. 22 type 2) exhibited more than 470 m / s. When the unidirectional prepreg with surface density of 1 layer was 254g / ㎠ and 65 layers of compression molding, the bullet width of 250mmⅩ300mmⅩ180mm thick bulletproof board was tested with AK bullet 7.62mm, and the antiballistic performance was over 730m / s. In addition, the weight of the bulletproof board is less than 1.4kg.

이상과 같이 본 발명은 폴리에틸렌 부직포 및 일방향배열 프리프레그를 적층하여 일정압력과 일정량의 열을 가하여 압축성된된 방탄판재은 그 방탄성능이 우수하여 직격탄으로부터 인명을 보호할 수 있는 것이며, 또한 가벼워 기동성, 이동성,을 구비할 수 있는 방탄복을 제공할 수 있는 것이다.As described above, the present invention provides a bulletproof plate material which is compressible by stacking a polyethylene nonwoven fabric and a unidirectional array prepreg and applying a constant pressure and a predetermined amount of heat, so that the bulletproof plate has excellent anti-ballistic performance and can protect human life from direct bombs. It is possible to provide a body armor that can be provided.
