The Cobalt 沭 bulletproof vest of Tongguan technology is well known, such as the one caused by the use of DuPont Kevlar's aromatic polyamide fibers. However, in some places, such as in Europe, where pistol possession is more restrictive, the law is a major threat, and in some countries it is even the most important. The first test standards for body armor protection against piercing were established in the early 1990s by national agencies in Britain’Switzerland and Germany. For example, 'The British Police Department ’s Department of Scientific Development (PSDB) standard adopted in 1993 allowed: Regarding the threat of psdb knife 1 and No. 5, the air is shot with a energy of 20 to 65 joules, if the energy is less than Or equal to 42 Joules' shall have the greatest knife knife after 5 mm of armor, penetrate; and if the energy is greater than 42 Joules, it shall have the maximum knife and knife penetration after armor of 1.2 (1.2 X in Joule energy · 45). The Central Bureau of Standards of the Ministry of Economic Affairs cooperates with labor and capital. The company prints most of the soft and flexible textile systems currently available. It is often not enough to prevent surface densities greater than 30 Joules when it is suitable for daily wear. Puncture force (use a German knife, as specified in the German regulations / grids (Richtlinie, Schutzwesten, 1994) or the PSDB knife) ° To prevent this order of penetration force, hybrid systems (which will Combination of metal or ceramic anti-piercing buttons with a textile backing material. A common problem with these hybrid systems is: front protection; pierced components are easy to bulk, bulky and unwound, especially when using small metal plates.

Anyone skilled in the arts may know that the restriction of the system is not unreasonable. In addition, the resin used in buried armor can annoyingly increase the surface density of the entire protection system. □ For this reason It is a flexible and lightweight protective material that can prevent bullets and provide anti-knife puncture properties at relatively high piercing energy levels, such as those specified by the British PSDB and Germany. SUMMARY OF THE INVENTION The present invention relates to flexible And light-weight material, which has enhanced piercing protection at high piercing energy levels, that is, piercing protection at energy levels greater than 30 Joules; the piercing protective material may be related to Ballistic components are disengaged to form an integral piercing And bullet protection material.

Description of the invention (3 Piercing protection when penetrating energy, that is: greater than 30 Joules: Case, the puncture protection material is combined with the ballistic component to form: = body piercing and bullet protection Materials. The whole piercing protection material family includes two components that form an integral protective material.

And pieces, [is a bulletproof component to form puncture-proof and bullet-recording materials. The ballistic component contains many layers, woven or Non-woven fabrics are based on tenacity fibers, such as para-aramid fibers, ultra-high molecular weight polyethylene, impact nylon, etc. Module (a) is a structure containing metal, which itself is Flexible and can hinder and prevent itself Pointed objects. Typically, this structure may have interlocking rings or a combination of rings and plates. The structure may be formed of steel or chitin containing armor. The armor shall be light and flexible, yet resistant to puncture. There are no other special requirements regarding formazan. However, if a formazan system is a metal ring, these metal rings preferably have a pinch of about 10 mm to about 20 mm. The diameter of the wire used to make the ring is 〃 The range may be from 0.2 to 2-0 millimeters. The component (b) is a material that absorbs impact energy, or a second layer of puncture-resistant lining or a combination thereof. The material that absorbs impact energy may be dimensionally stable Soft materials, among which, the thickness of t sharply reduces energy impact.

Description of the invention (4) Materials such as rubber or elastomer flakes or cinnamon can use a combination of woven and non-woven materials. In addition, single or multiple layers can be used The second layer of anti-stab The material may be a metal-containing structure such as a component U). If the material is formazan, there are no other special requirements for this layer. If the steel is caused by a welded ring, the better is: the welding The ring has a diameter of about 1.0 millimeter to about 20 millimeters. The diameter of the metal wire used to frame it may range from 02 to 20 millimeters. Typically, to maintain the total desired weight limit of the protective material of the present invention , Metal wire = diameter and therefore, the total surface density used in the second formazan layer will be less than that of the second formazan layer. The anti-penetration material for the second layer may also be single or multiple layers based on the following high-strength fibers Flexible warp-impregnated fabrics: for example, the Group 1 polyacrylamide fiber. The inter-strength strength polyethylene, nylon, etc. This is the preferred embodiment of the second layer of anti-penetration material. The flexible coated fabric layer includes a material capable of resisting penetration, fiber, and supporting materials = 3. These fibers are at least partially embedded in the supporting material to limit the fibers therein. Relative movement. This flexible impregnated fabric may additionally be defined as a kind of fabric. When tested at a surface density of 9.1 to 9.2 g / million and a surface density, it can block the attack energy of 25 joules, turning a metropolitan dihedral blade, Leaving no more than 16-20¾ meters of piercing '^ put on the back of the fabric, according to NU 010103

Description of the invention (6) The present invention has the following Characteristics: () the existence of 4 components (b) (the layer that absorbs energy) behind the plutonium layer Significantly increases the puncture resistance of puncture protection materials. As for the technical aspects of puncture protection, it is well known that the puncture resistance of the nail armor system is based on the ability of the system to absorb energy = > ⑼ When the high puncture energy, PP : When a puncture energy greater than 35 Joules is applied to a material with poor penetration and security, the second layer of anti-penetration material, such as a stomach layer or multiple layers of coated Kevlar fabric, prevents "big crying failure" 'Happened, this term is used to describe the residual energy of a knife that completely penetrates a protection system. (in) When coated " Kevlar " ® fabrics are used as the second layer of puncture-resistant material, because those fabrics themselves are bullet-resistant, the surface density of the puncture protection material is reduced because A ballistic component (c) is not required because the piercing-resistant material alone provides sufficient protection against the bullet, or the bullet component may have a lower surface density than would otherwise be required. Examples Unless specifically mentioned otherwise, the following examples of impulse penetration tests are carried out on the test device shown in the following illustration: • Falling bell • Test device ^ This machine uses a clock rod and a dead weight. The vertical free fall of the projectile is used as the reference.
