Exploring with dark eyes requires a firm belief. As for success, I don’t know when it will come. Everyone is mentally prepared. This time, I called Mr. Zhu, Qin Zhenhua and others to come over, and in fact I was notifying them.
, The research and development of tank armor is progressing slowly, you must be mentally prepared, we have notified in advance!
There is no way. If you want to build composite armor, you have to go through a tortuous and long road from nothing to something.
"Ceramic composite armor is the trend, but if this kind of armor is difficult, why don't we start from the most ordinary one?" Qin Zhenhua began to express his own opinions.
Of course, they hope that domestic composite armor can be developed quickly, but in many cases, this kind of thing cannot be rushed.
The principle of ceramic composite armor sounds very simple, it is to install a layer of ceramic between two armor plates. Although China is the birthplace of world porcelain, how many times does this kind of ceramic piece used in armor have to be explored.
Only those who can succeed are sometimes even depend on luck. If you have good luck, you may be able to do it all at once. If you have bad luck, you are at the door, but you can't break into the door.
This takes time and requires accumulation.
Everyone is aiming at Western standards, so they are considering using ceramic armor to meet their needs. But now, Qin Zhenhua first proposed the most ordinary ceramic composite armor!
When everyone heard Qin Zhenhua's words, they frowned.
"You mean, fiberglass armor?" Mu Guijin asked.
Qin Zhenhua nodded: "That's right! The West uses ceramic armor, and the Soviet Union uses fiberglass armor. Haven't we always learned from the Soviet Union? Haven't you ever considered starting with this method?"
The Soviet Union valued armor the most, so it was also the first to use composite armor. They creatively used composite armor on the T-64 main battle tank.
According to the public statement, this armor has three layers, the outer layer is 80mm thick steel armor, the middle layer is 104mm thick glass fiberboard, and the inner layer is 20mm thick steel armor, that is, the steel plate is entrained with glass.
Fiberboard.
The fiberglass board with the same weight has an elastic resistance of more than the armored steel of the same weight, but the thickness has increased. According to the Soviets, their T-64 main battle tank has only increased its weight by 4 tons, and the front main armor
The resistance to armor-piercing bombs has increased by almost 50%, approaching the protection level of 300 mm homogeneous armored steel; the resistance to armor-piercing bombs has increased by almost 90%, reaching the protection level of about 600 mm homogeneous armored steel.
Starting from the composite armor, the measurement indicators of tank armor have become equivalent to the level of how many millimeters of homogeneous steel. At the same time, the effect of the confrontation between different armor-piercing methods has also begun to be different.
When everyone heard Qin Zhenhua's words, they shook their heads helplessly.
"In fact, we have also studied fiberglass, and later found that the method used is almost the same as ceramic armor. Since they are all the same research methods, why don't we skip the research on fiberglass armor and put it on ceramic armor directly?
”
This is also a helpless choice. Since you have to have it, just use a better route.
Today, I asked everyone to come here to discuss the route issue. After hearing this explanation, Qin Zhenhua shook his head: "No, of course it is different. We have ready-made fiberglass armor. We have ready-made finished products to learn from. I heard... we are planning to build one.
T-72 is back?"
This plan has actually been around for a long time, but there has been no movement. The foreign affairs department is still working hard, and once the T-72 is returned, it will definitely be given to the tank design institute.
"Although we can get a simplified version of the T-72, its front armor also uses fiberglass composite armor. So, as long as we get this tank and study it, we will definitely gain something.
of."
In fact, if there is no process, even if the sample is placed in front of you, there will be no effect. If you don’t know the process, you still cannot produce it. If there is a slight error in the process, the ones that come out may be scrap.
However, having samples is better than not having samples, at least there is a reference.
"In the future, we will definitely export more tanks. Our domestic army must also be equipped with advanced tanks. The performance will definitely be different for self-use and export." Qin Zhenhua continued: "If you can do it in China, then self-use.
Isn’t it better to use ceramic armor and export fiberglass armor?"
If the military is present, they will definitely agree with Qin Zhenhua's proposal.
"With the sample, you may not know the process." Mu Guijin said: "Besides, now, the import of T-72 is still not a single word."
The atmosphere in the conference room is a bit unstoppable here.
Just as everyone was thinking, Wang Xiaoyu's voice appeared: "Well, if you need it, can you come to the university for help? I know that there is a professor Mao in our college who specializes in materials. He has been recently
The production process of glass fiber has been developed, what is it called…”
"Chiyao wire drawing method?" Fang Lao on the seat suddenly spoke: "Is this production process? Is it?"
He was a little excited.
"That's right, it's this process." Wang Xiaoyu said: "The process has been developed, and it seems that he is looking for a factory to do experiments."
"Okay, sure enough, there are talents everywhere, but we didn't find one before, and we didn't find one! Xiaoyu, you made great contributions to us this time!" said Old Fang.
Qin Zhenhua was quickly searching for information in his mind, but he was not omnipotent. He specialized in his profession. After searching for a long time, he could not find the production materials related to these in his memory.
Glass fiber has been used in the current industrial production. After all, it has many advantages. As for the use of armor, of course, it is high tensile strength. The glass fiber used for specific tank armor must have different techniques, but
, the principle of change is always the same, and it is closely related to ordinary glass fiber production.
There are two types of glass fiber production processes: two-time molding-crucifix wire drawing method, and one-time molding-pool kiln wire drawing method.
There are many processes in the previous process. First, melt the glass raw material at high temperature into glass balls, then melt the glass balls twice, and draw the high speed to make glass fiber raw silk. Since it needs to melt twice, the energy consumption is high, the molding process is unstable, and labor is done.
Low productivity.
The latter is a new production method. It directly melts raw materials such as wax in the kiln into a glass solution, removes bubbles and then transports them to the porous leaking plate through a passage, and draws them at high speed to make glass fiber raw wire.
Because such porous leakage plates are as high as hundreds, the production process is simple, energy saving and consumption reduction, stable molding, efficient and high yield.
However, these processes cannot be developed in the tank design institute. Now, there are professors from the Capital University of Technology that are specializing in these processes, which can make up for their strengths and weaknesses. If you bring the fiberboard in the armored mezzanine of the T-72 tank over, find
Professor Mao may be able to make a breakthrough soon after researching this together.
