Chapter 85 Recombination and Explosion
Hearing that Gao Zhendong had more specific ideas, Mr. Guan became more interested: "You say it, you say it."
This time Gao Zhendong did not find any reason. Instead, he directly said that he thought about it: "I thought about a question when I was working on materials. Materials are often brittle when they are hard, and soft when they are tough. Is there a possibility to combine them?"
Mr. Guan pondered: "But when two alloys are smelted together, they will become a new alloy, and the performance is still uncontrollable."
Gao Zhendong smiled: "But if what I think is not What about two alloys, but two materials with completely different properties? Combining them does not require smelting, but physical combination, such as doping, lamination, and coating.”
Mr. Guan did not follow his train of thought: "I don't quite understand what you mean."
Gao Zhendong gave an example: "Let me give you an example."
Mr. Guan motioned for him to pause. , turned to look at Director Yang and Mr. Chen with a little embarrassment: "Director Yang, Mr. Chen, I may ask you to step aside for a while."
The two of them suddenly realized that this was Maybe the secret of the armor will be involved later, so he laughed and walked out of the room.
Consultant Lin also took several soldiers out and distributed them in several corners outside Gao Zhendong's house, surrounding Gao Zhendong's house.
Factory Director Yang saw that Mr. Guan and Gao Zhendong still had to talk, but they always had to treat others to a meal. It seemed inappropriate to go back to the factory soon because they didn't know how long they would talk.
At this moment, Shazhu was humming a song, carrying a small lunch box, and walked home.
As frequent visitors to the canteen, Director Yang and Mr. Chen both knew Shazhu. Director Yang rolled his eyes and took the initiative: "Master He."
Silly Zhu I was shocked and thought, Hey, I just bring a small lunch box, and the factory director and chief engineer will come to arrest me? As for what?
Si Zhu responded vaguely, and Director Yang continued: "Master He, please excuse me. I will write you a note. You will go back to the factory immediately and bring enough food for ten people. Let’s go back to your house to cook the food. The guests from the factory will come to your house for dinner later.”
How come Director Yang is the director? There is nothing to say about his adaptability.
When Silly Zhu heard this, he thought this matter was easy to handle. He responded, put down his things, turned around and went to the factory.
At Gao Zhendong’s house, Gao Zhendong was talking to Mr. Guan about his thoughts: “We use a thinner 3Z-T1 steel plate for the first layer, and use phenolic resin and fiberglass cloth as an adhesive for the second layer. And the buffer layer, the third layer is alumina ceramics containing chromium, the fourth layer is still a buffer layer of resin and glass fiber, and the last layer uses a thicker 3Z-T1 steel plate to create a composite armor plate.”
This is actually the structure of the earliest composite armor target plate used in China. It really appeared in the late 1970s. At that time, it was already lagging behind the international advanced level, but now, it is well ahead.
Mr. Guan carefully considered Gao Zhendong’s example: “Huh? It’s interesting, layered and composite, each performing its own duties.”
Gao Zhendong shook his head: "It's not just as simple as performing their own duties. Taking the metal jet of an armor-piercing projectile as an example, when it passes through the entire composite armor plate, it has to go through five layers of boundaries: hard-soft-hard-soft-hard. It will have a great impact on the stability of the jet. "
"And I am thinking that the entire set of composite armor plates will move violently at different speeds and directions under the high-speed impact of the metal jet or armor-piercing projectiles. Can it have the effect of cutting off jets or armor-piercing projectiles?"
After hearing this, Mr. Guan thought about the picture carefully for a while while drawing a picture in his notebook. After a long time, Mr. Guan raised his head and was very pleased: "That's the reason. It's interesting. It's interesting. Although chromium-containing corundum (alumina ceramics) is difficult to burn, it is not impossible to make. The weight of the entire armor plate will be much lighter than the average steel armor. As for the protective performance, we will know by doing experiments! But this theory sounds very feasible."
After thinking about it, he smiled at Gao Zhendong: "Comrade Zhendong, you. You have already thought about the structure and materials of the composite armor so clearly, so I guess you have some idea about the specific thickness of each layer, right?”
With Gao Zhendong's current achievements and status, he can have the capital to directly use his "genius mind" to explain some seemingly incredible ideas and technologies whose origins are unclear, especially in the field of materials.
So he didn’t do much to cover it up and reported it directly: “My idea is that the first layer is mm, the second layer is mm, the third layer is mm, the fourth layer is mm, and the last layer. mm, so that the thickness of a single armor plate is appropriate, and the weight is controlled within a range that is more convenient for human maintenance. According to my estimation, the ability of this armor plate to protect against armor-piercing bullets and armor-piercing bullets should be better than that of average steel armor of the same thickness. Stronger.”
The ability to protect against armor-piercing projectiles and armor-piercing projectiles is calculated separately. Generally speaking, for the same armor plate, the ability to protect against armor-piercing projectiles is much lower than the ability to protect against armor-piercing projectiles, especially when the tail fin is stably detached. After the emergence of ArmorPiercingFinStabilizedDiscardingSabot (APFSDS for short).
Gao Zhendong did not measure the thickness to millimeters, which would have been too outrageous. Instead, he chose a number that was closest to an integer of 10. However, it did not have a big impact on the performance or was even slightly better, but the weight was slightly smaller. A little bit bigger, it won't have much impact.
He directly gave Mr. Guan the parameters of the composite armor, so that he could avoid detours and speed up the research progress of Mr. Guan and the others. In fact, for this kind of armor plate, all Mr. Guan and the others have to do is It's just an experiment.
In fact, Gao Zhendong also knows better composite armor structures, materials and processes, but those are things after the 1990s. For now, the processing is too complicated, so we can only leave it to the future.
Mr. Guan memorized Gao Zhendong's entire design and was very happy: "Zhendong, if the test is successful, you will be the chief engineer of this composite armor model, haha."
Gao Zhendong rubbed his head: "Hey, it doesn't matter. Actually, I have another idea." Anyway, they are here, so I might as well finish it all at once to give them a little shock to Zhendong.
Mr. Guan’s eyes are dull, what? Do you have any ideas? Are you an idea machine?
After reacting, Mr. Guan opened another page in his notebook.
This time, what Gao Zhendong brought out was explosive reactive armor. In fact, this thing is not suitable as main armor, but it is very suitable for upgrading the protective capabilities of old equipment.
Gao Zhendong explained the principle, structure and material selection of explosive reactive armor to Mr. Guan, and finally said: "The advantage of this armor is that on the basis of the same anti-armor penetration capability, the weight is further reduced. But there are also shortcomings."
Mr. Guan was still shocked by Gao Zhendong's genius idea and asked a little stupidly: "What are the shortcomings?"
He didn't even bother to think about it himself. The genius is here, I just ask.
There is another chapter today.
The thickness of each layer of this composite armor target plate is actually public now and can be easily checked. However, in order to avoid trouble, I have hidden it. Please understand.
The unit that engages in tanks is not just the Prairie Tractor Factory mentioned in this article. The reason is the same as above.
I will not bother to explain similar situations in the future.
