How? Post-processing, of course!

He didn't plan to introduce a large number of equipment to produce bulletproof inserts, because the technical content of this thing is not high, and the fight is the cost, but he still doesn't have to worry about others stealing his business, because he still has a unique job!

In bulletproof equipment, helmets use aramid fibers or polymer polyethylene and other materials, and cuirasses usually use bulletproof ceramics, including alumina, silicon carbide, and boron carbide.

Alumina has the highest density, low processing threshold, very cheap price, relatively low hardness, and is the first choice for the pursuit of cost performance. Silicon carbide is neither up nor down.

For example, take the same NIJ3 grade plate as an example, the alumina ceramic plug-in is two or three hundred grams heavier than the silicon carbide ceramic plug-in, and four or five hundred grams heavier than the boron carbide ceramic plug-in, but the price is only half of silicon carbide and one-sixth of boron carbide.

Therefore, many engineers are wondering: can the alumina ceramics be increased to the level of boron carbide, and the price will not increase too much?

Is there a way?

Of course!

After repeated research, the engineers finally found a suitable process, such as the use of electron ray vacuum coating, sputtering vacuum coating or chemical vapor phase evaporation and other strengthening process methods, the surface of the alumina ceramic is coated with a layer of silicon compound film, so that the original silver-white alumina bulletproof insert plate becomes black.

Before this technology, the bulletproof insert is layered, and a layer of anti-cracking cloth will be pasted on the front of the ceramic bulletproof insert to prevent people from being injured when the ceramic is broken, which is generally to hurt others, just like the explosive reactive armor of the tank, and then paste a special aramid or polyethylene fiber material backplate to form a three-layer chocolate structure, especially in the early days, the ceramic insert is not a whole piece, divided into a mahjong block, this kind of wrapping is necessary.

Now, one board is enough!

Of course, the process is not only coating, but also more importantly, it is treated at a high temperature of more than 1,200 degrees Celsius, so that the alumina ceramics can be tempered to form alumina ceramics with ultra-high strength. Not to mention the intermediate-power ammunition of automatic rifles, in real combat, even full-power machine gun bullets can be blocked.

There is no technical content in firing alumina ceramics, it is a labor-intensive industry, Qin Feng does not plan to get involved, and hand it over to the ceramic factory to do, as long as he masters the next two processes, he can firmly control this product in his own hands.

This Pan Daqing still wants a copycat? Don't look at yourself to see if you have the ability!

The original bulletproof plate in his hand was about the same as blocking the bullets of a Type 79 submachine gun, and the power of the 56 bullets could not be stopped, so of course it was shattered.

At this time, after hearing other people's questions, Qin Feng replied sincerely: "Of course, after thousands of repeated trials and millions of R&D funds, we finally made this product, but the troops can rest assured that what we give to the troops is the cost price, and the R&D funds can be earned by exporting products." ”

Millions of R&D dollars? Pan Daqing was in tears there, if we were given millions of funds, we would definitely be able to make something similar, or even better!

Wait, we can't let them get away with this!

Pan Daqing looked at the hole in the board and gritted his teeth: "Leaders, although this board has not been pierced, it has also been broken!" If the next bullet hits this hole, it will definitely pierce the body armor! ”

Although I don't know what tricks Qin Feng played, now he has to tell the leaders that my bulletproof plate didn't pass, and his bulletproof plate is not qualified!

", on the battlefield, Lao Tzu hasn't seen two bullets hit the same place!" Li Runzhu became angry immediately: "Even if you can only block one bullet, it's better than something that shatters when you touch it!" ”

Qin Feng glanced at Pan Daqing: "Pan Gong, the bulletproof plate that was exploded was developed by you?" ”

"Yes, we developed it, what's wrong? Failure is the mother of success, as long as we have enough R&D funds, we will also succeed! ”

"Then tell me, what is the bulletproof principle of your bulletproof plate?"

"What else can it be, just hit it. In the past, it was soft body armor, and the emphasis was on overcoming rigidity with softness, but if we couldn't prevent rifle bullets, we could only overcome rigidity with rigidity. ”

"I mean the specific collision process."

"Concrete? It's our secret! What if you hear it and learn it? ”

"Say! It's all engaged in the military industry, and it's not a leak! Leader Yang, who had been gloomy in face, suddenly shouted.

Pan Daqing's face turned white all of a sudden: "This, this, this..."

He didn't make this thing, how did he know what principle was used in it, and he couldn't say anything.

"Pan Gong, didn't you develop this thing? How could you not even know this? ”

"I, I..."

"If you don't tell the truth, go to court!"

"This thing, I bought it from the ceramic factory in Sugar Mountain, this thing must be used on body armor, I just, just..."

"Pan Gong, how can you do this?" Leader Qin's face also became difficult to look at: "Our R&D funds are relatively scarce, and this kind of technology is very difficult, it doesn't matter if you can't get it, but it is absolutely impossible to cheat like this!" I'll say hello to your leaders and transfer you out of your research position, so let's go! ”

Pan Daqing left alone, and Qin Feng's voice sounded behind him.

"Ladies and gentlemen, let me introduce the principle to you. We know that the bulletproof plate made of metal material in the past will produce plastic deformation when resisting the impact of the warhead, thereby absorbing energy. However, our ceramics do not produce any plastic deformation, it relies on its own high strength and high hardness characteristics to passivate or even break the warhead, and the ceramic surface is crushed to form small and hard fragments, in the process of absorbing the energy of the high-speed warhead, so that it stops moving. ”

Qin Feng said with foaming stars, but when he looked around, everyone was at a loss, obviously not understanding!

"To put it simply, the energy from the bullet is used on the ceramic, turning the ceramic into foam, so there must be a pit left." Qin Feng briefly introduced: "If it is not blocked, then the entire ceramic may become fragments." ”

Everyone nodded.

"This is indeed a good thing, I think, we can purchase five hundred sets first, and complete the scouts on the mission." Yang Lao spoke.
