As for success, I don't know when it will come, everyone is mentally prepared, this time I called Zhu Lao and Qin Zhenhua and others to come over, in fact, I am also informing them that the research and development of tank armor is progressing slowly, you must be mentally prepared, we have notified them in advance!

There is no way, if you want to engage in composite armor, you have to go through a long and tortuous road from scratch.

"Ceramic composite armor is the trend, but if this armor is difficult, why don't we start with the most ordinary?" Qin Zhenhua began to put forward his own opinions.

Of course, they expect that domestic composite armor can be developed quickly, but, many times, this kind of thing is not rushed.

Ceramic composite armor, it sounds very simple, is to add a layer of ceramics between the two armor plates, don't look at the country is the birthplace of the world's porcelain, but the ceramic pieces used on this armor, that is how many times to grope to succeed, sometimes, even depends on luck, lucky, maybe it will come out all of a sudden, bad luck, just at the door, but can never break in.

It takes time, it takes accumulation.

Everyone is aiming at Western standards, so what they are thinking about is using ceramic armor to meet their needs, but now, Qin Zhenhua first proposed the most ordinary ceramic composite armor!

Hearing Qin Zhenhua's words, everyone frowned.

"You mean, fiberglass armor?" Mu Guijin asked.

Qin Zhenhua nodded: "That's right!" The West used ceramic armor, the Soviet Union used fiberglass armor, haven't we always been learning from the Soviet Union? Haven't you considered starting with this method first? ”

The Soviet Union attached the most importance to armored power, so it was also the first to use composite armor, and they creatively used composite armor on the T-64 main battle tank.

Remember the URL

According to the public statement, this armor has three layers, the outer layer is 80 mm thick steel armor, the middle layer is 104 mm thick fiberglass plate, and the inner layer is 20 mm thick steel armor, that is, the steel plate is entrained with fiberglass plate.

According to the Soviets, the weight of their T-64 main battle tank has increased by only 4 tons, and the armor-piercing ability of the front main armor has increased by almost 50 percent, which is close to the protection level of 300 mm homogeneous armor steel; The resistance to armor-piercing shells has increased by almost 90 percent, reaching the level of protection of about 600 mm of homogeneous armor steel.

Starting from composite armor, the indicators measured by tank armor have become equivalent to the level of how many millimeters of homogeneous steel, and at the same time, the effect of confrontation begins to vary depending on the armor-piercing method.

Hearing Qin Zhenhua's words, everyone shook their heads helplessly.

"Actually, fiberglass, we have also studied, and later found that the way used is almost the same as ceramic armor, since it is the same research method, why don't we skip the research of fiberglass armor and go directly to ceramic armor?"

This is also a helpless choice, since you have to have it, simply use a better route.

Calling everyone over today is to discuss the issue of this route, hearing this explanation, Qin Zhenhua shook his head: "No, of course it's different, fiberglass armor, we have ready-made products to learn from, I heard... Are we planning a T-72 to come back? ”

In fact, this plan has been in place for a long time, but there has been no movement, and 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 what we can get is a simplified version of the T-72, its front armor is also made of fiberglass composite armor, so as long as we get this tank, we will definitely gain something from disassembling and researching it."

In fact, if there is no process, even if the sample is placed in front of you, there is not much effect, I don't know the process, or I can't produce, and the process is slightly wrong, and it may be a waste product.

However, it is better to have samples than no samples, at least there is a reference.

"In the future, we will definitely export more tanks, and our domestic army will also be equipped with advanced tanks, and the performance will definitely be different for our own use and export." Qin Zhenhua continued: "If it can be done domestically, then it is better to use ceramic armor for self-use and fiberglass armor for export, and use fiberglass armor for export?" ”

If the military were present, they would definitely express their absolute approval of Qin Zhenhua's proposal.

"If you have a sample, you don't necessarily know the process." Mu Guijin said: "Besides, now, the import of the T-72 has not been skimmed. ”

The atmosphere in the conference room is a little cold here.

Just as everyone was thinking, Wang Xiaoyu's voice appeared: "That, 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, and he has recently tackled the production process of glass fiber, what is it called..."

"Pool kiln drawing method?" Fang Lao, who was in the seat, suddenly spoke: "Is this the production process?" Isn't it? ”

He was a little excited.

"That's right, that's the process." Wang Xiaoyu said: "The process has been developed, and it seems that we are looking for a factory to do experiments. ”

"Okay, sure enough, there are talents everywhere, but we didn't look for them before, and we didn't dig them! Xiaoyu, you have made a great contribution to us this time! Elder Fang said.

Qin Zhenhua was looking for information in his mind, but he was not omnipotent, he had a specialization in the art industry, and after searching for a long time, he did not find the production materials about these in his memory.

Glass fiber has been used in industrial production now, after all, it has many advantages, as for the use in armor, of course, it is high tensile strength. The specific fiberglass used in tank armor must have a different process, but it is always the same, and it is very related to the production of ordinary fiberglass.

There are two kinds of glass fiber production processes: two-time molding-crucible drawing method, and one-time molding-pool kiln wire drawing method.

The previous process is various, first the glass raw material is melted into glass balls at high temperature, and then the glass balls are melted twice, and the glass fibers are made into glass fiber precursors at high speed. Because it has to be melted twice, the energy consumption is high, the molding process is unstable, and the labor productivity is low.

The latter is a new production method, which directly melts raw materials such as pyrophyllite into a glass solution in the kiln, excludes air bubbles and transports them to the porous leakage plate through the channel, and is drawn into glass fiber precursor at high speed.

Because such porous leakage plates are as high as hundreds, the production process is simple, energy saving and consumption reduction, stable molding, high efficiency and high yield.

It's just that these processes are impossible to develop in the tank design institute, and now, there are professors at the Capital University of Technology who are specializing in the study of these processes, which can just learn from each other's strengths, if you get the fiberboard in the armor interlayer of the T-72 tank, and find this Professor Mao to study together, maybe you can break through soon.
