Chapter 294： Bulletproof material (below)

There are several types of bulletproof steel plates of the original old red flag, but Guo Tailai feels that this kind of bulletproof material 20 years ago should have a better choice and can be abandoned.

At present, the latest bulletproof steel plates are available at home and abroad, and the other is the composite armor currently used in active tanks. Of course, with the unique requirements of Guo Tailai, high-strength bulletproof titanium alloy is also an option. each

What kind of labeling property, Guo Tailai does not look at it for a while, the material is taken to the sample, sent to the shooting range to see the effect. Check

During the manufacturing process of the car, there were general assembly and representatives of the Central Guard Bureau, and they were all concerned about the target range. There was no problem at all. on

On the shooting range of the Kyrgyzstan military division in the Shengjing Military Region, the square plates of thirty centimeters by thirty centimeters made of several materials are lined up. Guo Tailai directly considered the thickness of 10 millimeters, and other thicknesses, so that Zhang always differentiated the bulletproof level when they were producing in order to open different grades. What Guo Tailai has to do is only the highest level.

Various models of pistols, submachine guns, assault rifles, sniper rifles and various types of bullets, take turns to see the actual effect to determine the bulletproof level. Similarly, bulletproof glass is also such an operation. However, the glass is directly selected to be ten centimeters thick, so as to ensure that nothing is lost. Correct

The representative of the Central Guard Bureau was quite satisfied with the live ammunition test requested by Guo Tailai. This is much more intuitive than looking at what data, and it also makes them more aware of the ballistic performance of these materials. hand

When the guns are on the line, they basically just tickle these different bulletproof panels. There are some marks on the top, which are basically negligible. Flush

The front gun, because the pistol is used, but the length of the barrel is longer, but the same does not leave much impression. Even the p90, which claims to be able to penetrate the titanium bullet-proof vest, is fascinated by the various bullet-proof panels of 50 mm thickness. small

Caliber assault rifle, 5.56mm caliber, using NATO bullets, 10 meters distance, 950 meters per second bullet velocity, can play a pit of one or two millimeters. It can be said that this has reached the b5 level of bulletproof level.

7.62mm caliber assault rifle, NATO 51mm soft lead nuclear bullet, hit a pit of two to seven millimeters, but there is no way to penetrate. This is the case with the b6-level bulletproof standard.

Replaced with 7.62x51mm NATO standard hard steel nuclear bullets, 10 meters away, ordinary bulletproof steel plates are directly penetrated. The composite armor is fine, leaving a pit of four or five millimeters, and the titanium alloy bulletproof board is shallower.

Basically, in addition to ordinary bulletproof steel plates, composite armor and titanium alloy ballistic panels can achieve b7 level bulletproof function as long as they reach this thickness. a

K47 uses the Soviet system 7.62x39mm intermediate power bullet, the bullet power is much worse than the NATO system bullets, sweeping in the car is no problem. most

After changing to a 12.7mm NATO bmg ordinary bullet, basically a shot can be directly penetrated. Not to mention the 12.7mm armor-piercing projectile, which is definitely more lethal and unprotectable. "

Can you thicken? "The representative of the Central Guard Bureau, surnamed Liu, is a colonel. Looking at this effect, I can't help but ask. For the use of the head, of course, the safer the better."

Ordinary cars only have an average thickness of less than one millimeter. Guo Tailai smiled and said: "We are already ten millimeters, a thickness of one centimeter. According to the size of our car body, for each additional centimeter of composite armor thickness, the car weight is estimated to increase by nearly two tons, and now it is already four tons. If it is aggravated, I am afraid it will affect the performance of the car. ”

"We don't have to be so thick in every part, mainly in the tank compartment of the passenger compartment and near the engine. The other parts use this thickness of steel plate. The main protective part is thicker, can't it?" Colonel Liu suggested: "This way Wouldn't it add too much weight? As far as I know, some state-owned armored cars use bullet-proof armor that is up to three centimeters thick."

“It can be.” Guo Tailai thought for a moment and said, “But we may have a better way.”

"Talk about it." Colonel Liu asked with great interest.

“The simplest, we use titanium alloy, it will be at least 40% lighter.” Guo Tailai quickly replied: “In addition, we can do some special mezzanine. Well, you can ask Professor Shi Zhicheng, Department of Materials, Shuimu University. The results of that research. If it can be applied in practice, we can consider the composite armor composed of multiple layers of soft and hard bulletproof materials, the effect will be better, and the weight can be greatly reduced." Liu

When the colonel listened, he immediately asked for a place to call and ask. It didn't take long for me to return to the test site: "The latest research results of Professor Shi will send some samples to test tomorrow."

After that, Colonel Liu also looked at Guo Tailai with a little doubt. It seems that he wondered how Guo Tailai knew Professor Shi’s research project.

"This study by Professor Shi is because of one of my thoughts." Guo Tai came to the vigilance of Colonel Liu and explained with a mouthful: "At the time, this research direction was discussed with Zhao Dong of the Southern Group."

After listening to Guo Tailai’s explanation, Colonel Liu’s expression eased slightly. These things can be investigated, Guo Tailai should not lie. Now he wants to know, plus the research results of Professor Shi, can achieve a strong bulletproof effect. general

The bulletproof rating of the civilian vehicles, b7 is already the highest, and these materials are enough to create. Guo Tailai wants to consider the safety of the review vehicles and daily vehicles used by the national leaders. It is imperative to use new technologies and pursue higher levels of bulletproof.

Under the insistence of Colonel Liu, the thickness of bulletproof armor increased to 1.5 cm. However, Guo Tailai intends to use titanium alloy bulletproof for these bulletproof cars. In addition, it will use titanium alloy-ceramic-titanium alloy-Kevlar-liquid bulletproof material-Kevlar-titanium alloy layering, soft and hard combination, bulletproof grade. Will be higher. Check

In the car reading program, all the materials transfer was given priority. The next morning, the project team received the latest research results of Professor Shi. What makes Guo Tailai happy is that the thickening shear fluid studied by Professor Shi is not a fluid state, but a gel state. It is normally soft and does not flow at the same time, but it is subjected to high-speed impact but in microseconds. The inside is hardened instantly.

It is a difficult point to combine these things together, but it is not a problem for Guo Tailai. In just one morning, Guo Tailai made a test target and tested it again. It

The previous steps are omitted, starting directly from the 7.62mm hard steel nuclear bullet. Successful defense. change

Into a 12.7mm ordinary bmg bullet, a shot went down, a large depression appeared in front of the target, revealing Kevlar and the gel layer. Turning over, the bullet did not penetrate the target, and the rear was just a small bump.

Once again, it was replaced with a 12.7mm bmg armor-piercing projectile. After one shot, the bullet was directly mounted on the target. Although the warhead penetrated the target, it was no longer able to go further.
