The venue has been cleaned up.

Instead, there is a large glass that is more than a meter high and more than a meter wide.

Underneath this piece of glass is a cement table, and on top of it is marble.

The glass is stuck between the simulated wall, and the glass and marble are fixed with glass glue.

Of course, this is prepared in the morning.

After negotiating with Li Ju, Lu Chen made this.

Because of making glass, Lu Chen bought two pieces of equipment and placed them on the fifth floor of Deep Blue Technology.

However, it is a miniaturized device, and it is already difficult to make such a large glass.

To make a bigger one, unless you go to the glass factory.

And it's just synthetic glass, it's not really made of two pieces of glass.

With such thick glass, the sound insulation effect is similar to that of the wall.

Lu Chen: "Please have a police officer." ”

Officer Hua is loading 54 rounds and inspecting firearms.

After coming to the stage, Lu Chen pointed to the glass wall: "After a while, I will stand in the back, and you can see the glass shooting." ”

Officer Hana: "Are you sure?"

"I'm sure. ”

Officer Hua raised his eyebrows: "Are you sure you want to do such a dangerous thing?"

Lu Chenlehe: "The bulletproof glass just now is for cars, so thin, this is the top bulletproof glass, four centimeters thick, glass plus film is a total of five layers, rest assured, there is no safety problem." ”

Barrage:

"666, the person who failed to invent the parachute also thought so. ”

"It's too dangerous. ”

The live broadcast room was quickly marked with the words "professional team experiment, please do not imitate".

Imitation requires a gun!

Lu Chen stood behind the wall and used the microphone: "Officer Hua, I'm ready!"

Lu Chen paid attention to the dynamics of the system while preparing.

Shock +100

Shock +100

Shock +100

Sure enough, if you don't dare to order anything exciting, the shock value will not rise.

Dry a little exciting, and the shock value soars.

Lu Chen was behind the glass wall, his hands in his trouser pockets: "Come on!"

Officer Hua didn't say a word, put on soundproof headphones, turned on the safety, and pulled the trigger.

"Bang!"

Barrage:

"Ale?"

"That's it?"

"Are you sure it's hit?"

On the bulletproof glass, there is only a shallow, no more than a pea-sized white mark.

If you want to say it, the effect is not much worse than that of a bullet directly hitting the rear steel plate.

If it weren't for the camera to follow quickly, I'm afraid the sailors wouldn't have been able to see where they were shot.

Lu Chen: "Officer Hua, don't save bullets, two more shots." ”

"Bang bang!"

Two more shots, one left a white mark the size of a pea.

A shot smashed a shallow crater.

Lu Chen motioned for Officer Hua to put away his gun, then walked out from behind the wall and waved to the camera.

The camera quickly stepped forward and focused on the site of the shooting.

"It can completely defend against 54, so how about the defense against the rifle?" Lu Chen: "Officer Hua, please change your equipment!"

Officer Hua changed into a rifle, and then said to Lu Chen: "This gun experiment, you can't stand behind the wall." ”

Lu Chen: "Introduce the specific parameters of this rifle and bullet to the sailors." ”

"03 rifle, 5.8 mm caliber bullet, in past tests, the penetration rate of three hundred meters to a centimeter-thick steel plate, one hundred percent. ”

One centimeter of steel plate at a distance of three hundred meters, the penetration is one hundred percent.

At a distance of fifteen meters, how about four centimeters of glass?

Even if the defensive power of this glass achieves the same effect as the steel plate, it is equivalent to a four-centimeter steel plate.

Whether the four-centimeter steel plate can block the bullet at such a close distance is not within the test range at all.

No one has ever conducted such a senseless test.

Because even a load-bearing wall thirty centimeters thick, if fired continuously by bullets of this caliber, will be pierced.

The rifle was not meant to be a single shot to test its power, and it was a burst of fire.

And it's a multi-person fire.

So no one has ever done this kind of test, and I don't know how.

Lu Chen was not worried at all: "Officer Hua, you come to test, I'll retreat." ”

Lu Chen already knew the result.

If it is an armor-piercing bullet of 5.8 mm caliber, then this bulletproof glass can be said to be useless at all.

If it is an ordinary bullet.

Lu Chen stood away, and Officer Hua pointed his gun down: "Attention, the staff at the scene tried to stand behind me after arranging the camera, and the people in front of him all walked farther away and wore soundproof headphones." ”

If you are concentrated by rifles at such a close distance, you will be saved from being sent to the hospital.

The wound that enters the human body is about the size of the mouth of a mineral water bottle, and the outlet is about the size of the mouth of a bowl.

When the main body is hit, large swathes of muscle will be torn apart, and there is no value and meaning of salvation at all.

Seeing that everyone had withdrawn to the rear, Officer Hua lifted 03 according to the technical maneuvers, and then pulled the safety bolt.

"Bang!"

The magnitude of the sound is completely different.

In such a closed environment, the sound is very loud!

On the other side, on the bulletproof glass, it seems that there has been a lot of damage to the structure.

I can't see what is going on inside.

Barrage: "Let's see if it's broken." ”

"Wear it, can glass be as strong as steel?"

"Bulletproof is not only about whether it is strong or not, but also about shockproof?"

In fact, in addition to shock absorption, bulletproof materials also have a very important performance, that is, heat absorption.

Once a large amount of heat has been absorbed, the kinetic energy of the bullet is converted into heat and dissipated.

Naturally, the power is greatly reduced.

The steel is too smooth and acts counteract when it absorbs heat.

Because the rotating bullet will generate heat in the friction of the warhead.

Don't look at the hardness of steel, but in terms of true bulletproof, steel can only be used as a conventional material, not a high-end material.

The lens came to the action camera.

On the side, the bullet slowly advanced.

Get into the glass and start drilling into it.

However, the speed is getting slower.

Slow to stagnate.

By the time the tail of the bullet entered the glass, it had slowed down and almost stopped.

Barrage:

"Don't worry, wait, as long as it can penetrate, the bullet will lose its restraint and speed up. ”

"The properties of this glass look a bit like a gel. ”

"I don't know, let's see. ”

"Hey, the bullet didn't penetrate! It didn't penetrate! It hasn't come out for so long!"

"A large bag bulged out on the reverse side of the glass, but there was no sign of penetration. ”

Penetrating? Thinking too much.

Unless it's an armor-piercing projectile!

Officer Hua had already noticed that he had not penetrated the bulletproof glass, and was very shocked.

It can defend against 54, and everyone is already surprised.

After all, this kind of glass has not appeared before.

Can't even wear a rifle?

Officer Hua raised his hand.

"Bang!" "Bang!"

Bullets fired continuously.

After each shot, a large crater will appear on the front of the bulletproof glass and a large bag will appear on the back.

However, the bullet was stuck inside, not moving an inch, and there was nothing to do about the bulletproof glass.

Lu Chen smiled.

In fact, the kinetic energy of the bullet has driven such a large piece of glass to deform, and it has been consumed.

And the heat transfer in the glass is actually very good, and after the heat transfer of the bullet spreads, the temperature gets lower and lower.

And when the freezing point of the glass arrived, the bullet was stuck.

Completely impenetrable.

Not to mention penetrating.

The bullet is actually two centimeters deep from the other side.

It is only because the glass is partially deformed and a bag is arched that it feels very powerful.

It's like if you punch the plasticine and deform it, but to break the plasticine with one punch, there is no doubt that it is a fool's dream.

Officer Hua pulled on the safety and put away the gun: "This ......"

"You really can't wear it?" Officer Hua wondered.

Lu Chen nodded: "I just can't wear it." ”

Officer Hua: "Amazing, wouldn't it be widely used in banks and other places with relatively high insurance levels, so that it will be much safer." ”

Lu Chen: "Actually, you criminal police also need it, cut it into the size of a shield, it will not be heavier than a steel shield, but you can see the situation in front of the shield clearly." ”

Officer Hua raised his eyebrows: "That's right!"

Lu Chenlehe: "We will develop similar products in the future." ”

"It's not too early, continue the experiment, and the last test product of the day, the bulletproof plate. ”

Barrage: "Bulletproof panels, isn't that something that's been obsolete for decades?"

"New?"
