There are many categories of body armor.

In today's world, the most famous should be the Kelarf material.

Since the advent of the Kehraf material, the essence of body armor has not changed much.

That is, there is a slight improvement in style, weight, and additional materials.

For example, the most popular plug-in type is now.

The additional materials are mainly ceramics and high-density ductile fibers.

Previously, it was ceramic inserts as the mainstream. Now it's ultra-high molecular weight polyethylene fiber.

The more high-end the fabric, the lighter the weight and the stronger the protection. The stronger the ability to resist bullet penetration and pulling.

However, high-end fabrics are very valuable. It is used to make body armor, and the cost is too high. So far, there is no pure fiber fabric body armor in the true sense of the word.

It's not that the technology doesn't work. It's the cost that can't be controlled. Only a portion of the experimental product can be produced.

The price of a piece of body armor should be under $10,000.

If it's more than $10,000, the price is a bit unaffordable.

Domestic body armor is currently made of Kelaf material.

There is almost no difference in performance from foreign armies.

The main thing is that there is not enough quantity.

It's hard to do one set per person.

"Give me a sample. Wang Buan said.

"Right now. Ding Chen immediately brought a set of body armor. And bulletproof helmets.

This is the highest level of body armor.

Level 6 protection.

It is claimed to be able to withstand the close-range fire of the 95 rifle.

Its main raw material is the Kelaf material. Then add a very hard clad metal insert.

In fact, the protection effect is not very good.

Bulletproof helmets, in particular, are not bulletproof.

It is shrapnel-proof. Of course, if you're lucky, you can also make the bullet jump diagonally.

Robot No. 2 began to analyze the materials and composition of the body armor.

Robot One began to analyze the materials and composition of bulletproof helmets.

At the same time, we will explore how to improve the ballistic performance while significantly reducing the weight.

Analysis data shows that this set of body armor weighs more than three kilograms. The heavy plugboard has not yet been plugged in. The composite metal plate weighs a full nine kilograms.

Body armor, capable of fighting bullets from assault rifles, is already of the highest rank. Among them, this composite metal steel plate is the essence.

If the insert plate is taken into account, then the overall weight of the body armor will be more than 12 kg.

Obviously, this is a very heavy burden.

Even special forces who endure heavy loads cannot bear it.

Especially when fighting in the mountains, heavy body armor is definitely the biggest obstacle. Severely affects the speed of action.

So much so that in some special operations, special forces prefer not to wear body armor. Rather take risks.

However, if the weight is reduced, the protection performance will be greatly reduced.

Whether it is a plug-in type or a stacked type, the bulletproof plate is relatively heavy.

Therefore, the first task at the moment is to reduce the weight of the bulletproof plates.

However, it is not possible to reduce the performance of the bulletproof plate.

If you can improve protection a little bit, that's even better.

At the very least, it needs to be able to meet the five-level protection standard. It is to withstand the close-range fire of the Type 56 submachine gun.

The muzzle velocity of the Type 56 submachine gun is 710 meters per second. The muzzle velocity of the bullet of the 95 rifle is 920 meters per second. Between the two, the gap is 210 meters. This is the difference between the five and six levels of protection.

A minute passed......

Three minutes passed......

Five minutes passed......

Data analysis is complete.

Start regrouping.

Look for the most reasonable structure.

Find the best combination.

Soon, new ballistic plates were formed.

It weighs only one-fifth of the original. The protection is five times better.

It uses the highest quality raw materials. Grade 6 cemented carbide, T1600 carbon fiber, and iolite ceramic.

Almost at the same time, the data analysis of bulletproof helmets also ended.

Its weight is also reduced. The protection performance has also been improved.

However, it cannot be compared with body armor.

The two are structured differently. Naturally, the data is different.

"Take your time. There is no hurry. Liang Ge said.

"I had a sample before. Wang Buan said lightly.

"Oh, how does it work?"

"It seems a little better than this. ”

"Really?"

"Really. ”

"Then let's try it. ”

"Okay. ”

Wang Bu'an issued an order for the nearest industrial park to quickly produce 50 sets of body armor and bulletproof helmets.

He has all the raw materials. Dozens of robot elves work together, and the speed is extremely fast. On average, it takes three minutes to produce a set.

"Send someone to fetch it back. Wang Buan said.

"Okay. Ding Chen immediately arranged manpower.

Soon, a Sword King Dragon helicopter quietly took off.

In less than half an hour, it brought back the body armor and bulletproof helmet smoothly.

This speed......

Tut-tut!

I feel that with the Sword King Dragon helicopter, you can even take off directly when you go out to pee.

Anyway, there is no cost. Any special forces can participate in the training. Any special forces soldier can become a master at piloting a helicopter.

The Chinese army finally lived a high-ranking life, like an ancient martial arts master.

Fly at every turn. With a whoosh, it was gone.

"Huh, so light?"

"yes! How can it be so light? How many pounds?"

"Seems too light, right?"

When the body armor was started, everyone immediately realized that something was wrong.

It's too light.

Feel up to three kilograms.

Maybe not even three kilograms. Could it be that there is no plug board installed?

However, on closer inspection......

It is true that there are no protective plug-ins.

With a weight of three kilograms, all the parts are already buckled. Nothing is missing.

"Where's the plug-in?"

"No, you don't. ”

"Huh, no plug-ins?"

"Don't you want to reduce the weight, what are you going to do with the inserts?"

"Yes, that's right. But ......"

"How can you defend against rifle bullets without a plug plate?"

"The body armor itself is already a fusion of the hardest inserts. It's just a plug board!"

"Really?"

"Won't it?"

"And such a design?"

Everyone was skeptical. It feels incredible.

The main reason is that its design concept is completely different from ordinary body armor. It doesn't need an additional clad metal insert?

Could it be that body armor alone can withstand the shooting of assault rifle bullets?

Joke......

Definitely kidding......

Without a special plug-in plate, I'm afraid that even a submachine gun can't be defended.

Even if it is a 79-type micro-impulse, its bullet muzzle velocity has reached 515 meters per second. The same can be deadly.

You must know that the higher the level of body armor, the more prominent the importance of protective inserts.

It can almost be said that the essence of body armor is on the insert board.

Without a plug board, it's simply a waste.

"You try. ”

"I'll try. ”

Ding Chen was also a little skeptical.

He was the first to put on the body armor and experience it carefully.

As a result, it feels really weird.

The main thing is that the weight has been reduced too much at once. Completely uncomfortable.

The previous body armor, put it on, it was absolutely heavy. The heavy steel plate is inserted, and it is even more incredible.

Jogging?

Don't even think about it.

It's good to be able to walk quickly.

If it is installed with a crotch insert, it is even more tragic, and it is difficult to even stride forward.

Protective?

Flexibility?

The two are absolutely contradictory.

You can't have both. You have to be the same trade-off.

If you want the highest level of protection, you have to endure the speed of the snail, and you have to endure the most faltering movements.

If you want the most flexible movements, you have to throw away the body armor.

However......

At this moment......

But do you feel that the two can be fused?

The current set of body armor feels completely devoid of the appearance of a steel plate.

Moreover, it seems to be relatively soft and does not affect the delicate movement.

Snipers refuse body armor.

Because it will hinder the accuracy of the hit.

"I'll try it too. ”

"Give me one. ”

"I'll do it too!"

Everyone put on their body armor.

Sure enough, it all felt very strange. Not used to it. But I feel good about myself.

There is no such heavy feeling of grievance at all.

It's like wearing a cotton coat in winter.

In general, it's bigger, longer, softer, lighter, and more comfortable.

It can protect more body parts.

Wearing it almost does not affect any movement.

Even if you have to crawl on the ground, there is not the slightest obstacle.

The point is, it's really light!

The weight saved can be carried with more ammunition supplies.

This is crucial for special forces, who often have to fight behind enemy lines. The more ammunition supplies you carry, the more survivable you will be.

Previously it was twelve kilograms. Now it's three kilograms. The gap in the middle. That's nine kilograms.

With a weight of nine kilograms, it can contain a lot of materials.

One person is nine kilograms, ten people are ninety kilograms.

What the special forces need most is actually light body armor.

Now, that dream has come true.

But how protective is it?

This must not be empty words. You have to do experiments. Shoot directly with a weapon.

There are no dummies for the time being. But it doesn't matter. Here are the stones. Pile up the stones and hang the body armor.

Get started.

Pile up stones.

Put the body armor over the pile of stones.

It still feels too light. The body armor was actually blown a little by the mountain wind that swept by.

Cheng Kailong squinted at Wang Buan, a little worried.

Wang Buan nodded confidently.

He made all the 270 engines. Not to mention a small body armor?

Seriously, it's not technical at all. It's all about the raw materials.

As long as the grade of raw materials is reached, it is not a problem to have four-level defense, five-level defense, and six-level defense.

Of course, the technical content of the raw materials is very high. It may be even more difficult than studying the engine of a missile.

"Can it really work?"

"Let's fire!"

"Good!"

Ding Chen personally experimented.
