In the surprised look of everyone, Zhang Xiaolei took out a piece of black cloth with a hard texture from the black plastic box next to it and handed it to everyone and said: "This is the new polymer liquid material that was hit by the bullet in the video. The part in the middle, the white dot in the middle is the impact point of the bullet in the video."

After hearing Zhang Xiaolei's words, everyone immediately focused their attention on the stiff black cloth she unfolded. There was a white spot in the middle with some scratches on it. Looking carefully, it was some metal left by the bullet. crumbs.

Wang Lianggong took this piece of black cloth from Zhang Xiaolei's hand, and then looked through it carefully.

"It's heavier and thicker than ordinary cloth, and the texture is relatively hard. It doesn't feel as soft as shown in the video." Wang Lianggong kneaded it, and then asked Zhang Xiaolei, Wu Hao and others. look.

Zhang Xiaolei smiled and nodded, then took out another piece of black cloth from the box, nodded to everyone and said: "Yes, this new polymer liquid material will solidify instantly after being subjected to huge pressure. Hardens, thereby resisting the kinetic energy and penetration of the bullet.

Subsequently, this new polymer liquid material will soften little by little over time and return to its soft state. But after all, it has been solidified once due to gravity impact, so even if it takes a long time to recover, it is somewhat difficult to return to its original state. "

Speaking of this, Zhang Xiaolei showed the softer black cloth in her hand, and then said to everyone: "The piece in my hand is a new polymer liquid material that has not been hit by a bullet before it solidifies. Please take a look. , it is much softer than the piece that was solidified by the impact of the bullet."

After hearing this, everyone looked at the piece of black cloth displayed by Zhang Xiaolei. Sure enough, this piece of cloth was much softer than the previous piece of cloth, and it felt not much different from ordinary cloth.

Wang Lianggong, who was somewhat unconvinced, took the piece of cloth from Zhang Xiaolei's hand and carefully compared it with the piece of cloth just now. But I still didn't find anything strange. The textures and materials of the two materials looked the same, except that one was softer and the other was stiffer.

"How is the protective performance of this material? Can it withstand rifle bullets?" Another lieutenant colonel wearing woodland camouflage, an Air Force flag hanging on his shoulders, and a collar badge of 2 cents couldn't help but ask. .

After hearing the lieutenant colonel's question, everyone turned to look at Zhang Xiaolei.

After Zhang Xiaolei heard this question, she didn't have much reaction. Instead, she smiled slowly and said: "The protective performance of this material is relatively strong, and it can withstand 7.62 mm round-headed eggs within a distance of ten meters." shooting.

In the neck, elbow joints, crotch, leg joints and other parts of our special mechanical exoskeleton protective armor, we usually use two layers of such materials for sewing, so that its overall protective performance is basically It can withstand pistol and submachine gun bullets, and also has certain protective capabilities against rifle bullets.

Although it cannot completely resist the penetration of bullets, it can greatly reduce the penetration force of bullets. A large part of the bullets are stuck on the material and are not completely soaked. "

"Two layers, why not just use three layers? Wouldn't the protective performance be stronger?" The lieutenant colonel couldn't help but wonder.

Hearing the lieutenant colonel's inquiry, Zhang Xiaolei said with a smile: "The main consideration is the flexibility of movement. If the materials at these movable joints are too stiff, it will not be conducive to the movement of personnel, and it will also be uncomfortable for personnel to wear and use. or restricted movement.

Therefore, after repeated trials, we believe that two layers are more suitable. It takes into account both the protective performance and the softness of the material. Of course, if this product is equipped with troops in the future, we will also modify these parts according to the usage opinions of the troops. We hope that we can reduce the material to one layer to make it more flexible and lightweight. If we want the protective performance to be more powerful, then we can add one or more layers on top to give it better protective performance. "

After listening to Zhang Xiaolei's introduction, everyone present nodded. Indeed, this material is very good, but it must be used according to actual needs.

"I have a question." Luo Kai said at this time: "How long does it take for this material to become soft after being hit by a bullet? If these parts are hit by a bullet on the battlefield, because of the material The reason for solidification and hardening is that the soldiers wearing this equipment will also have limited movement due to the hardening of the material."

"Good question." After hearing Luo Kai's question, everyone couldn't help but agree. This is indeed a question.

After Zhang Xiaolei heard this question, she nodded with a smile and replied: "This material basically absorbs the kinetic energy of the bullet after it is hit and solidifies. When the kinetic energy of the bullet disappears, the material does not continue to be subject to external pressure. Afterwards, the material will soften immediately, and it will basically only take a few minutes to soften again. Of course, it will definitely not return to its original state.

Therefore, this material is only used for the protection of these soft movable joints, which account for less than 20% of the human body, and many places are also equipped with armor protection, so basically there will not be any big problems. "

Everyone also affirmed after hearing this. Indeed, as Zhang Xiaolei said, it only accounts for a very small part of the human body. If there is no such material protection, then the protective performance of this area will be weakened, which will undoubtedly become the weakness of the opponent's attack.

However, if the armor is completely covered, it will affect the wearer's flexible movement. The use of this new polymer liquid material combined with composite armor is undoubtedly the best way at present.

I am more interested in this material. Wang Lianggong turned to Wu Hao and the others with the piece of black cloth in his hand and said, "This is just a piece of material that has such excellent protective properties. If we use this material to make bulletproof vests and bulletproof inserts, then its The protective performance is much stronger than the current body armor and bulletproof inserts.

In addition, we can also use it to make some invisible body armor that fits our human body better. It looks no different from ordinary clothes. It is soft in texture, but can withstand attacks from the enemy at critical moments.

Use it to protect the personal safety of some important personnel, and it is much easier to use than ordinary body armor today. Wear it inside and it won't be visible when you put on clothes on the outside, making it perfect for attending various occasions without embarrassment or inconvenience. "
