Chapter 85 Recombination and Explosion

Hearing Gao Zhendong's more specific ideas, Guan Zong became more interested: "Tell me what you want to say."

This time Gao Zhendong did not give any excuses, but directly said that it was his own idea: "When I was working on materials, I thought of a problem. Hard materials are often brittle, while tough materials are soft. Is there a possibility to combine them?"

Guan Zong pondered and said, "But when the two alloys are melted together, they will become a new alloy, and the performance is still uncontrollable."

Gao Zhendong smiled and said, "But what if I am not thinking of two alloys, but two materials with completely different properties? To combine them, we don't need to melt them, but can combine them physically, such as doping, layering, and coating."

Mr. Guan didn't follow his train of thought: "I don't quite understand what you mean."

Gao Zhendong gave an example: "Let me give you an example."

General Manager Guan signaled him to pause, and turned to look at Director Yang and General Manager Chen with a little embarrassment: "Director Yang, General Manager Chen, I may ask you to step aside for the next words."

The two men suddenly realized that this might involve the secrets of the armor, so they laughed and walked out of the house.

Staff Officer Lin also went out with several soldiers and surrounded Gao Zhendong's house in several corners.

Director Yang saw that General Manager Guan and Gao Zhendong still had to talk, but he had to treat them to a meal. It didn't seem appropriate to go back to the factory soon because he didn't know how long they would talk.

Just at this moment, Sha Zhu was humming a song and walking towards home with a small lunch box in his hand.

As frequent customers of the canteen, Director Yang and General Manager Chen both knew Sha Zhu. Director Yang's eyes turned and a plan came to mind: "Master He."

Sha Zhu was shocked and thought, "Oh my god, I just brought a small lunch box, and the factory director and chief engineer came to arrest me? What's the big deal?"

Sha Zhu responded vaguely, and Director Yang continued, "Master He, please excuse me. I'll write you a note. Please go back to the factory immediately and get enough food for ten people. Then go back to your house and cook. The guests from the factory will come to your house for dinner later."

Why is Director Yang the factory director? His ability to respond is beyond reproach.

When Sha Zhu heard this, he thought it was an easy matter, so he agreed, put his things down, and went to the factory.

At Gao Zhendong's home, Gao Zhendong was talking to General Manager Guan about his ideas: "We use a thinner 3Z-T1 steel plate for the first layer, phenolic resin plus glass fiber cloth as an adhesive and buffer layer for the second layer, chromium-containing alumina ceramics for the third layer, and resin plus glass fiber as a buffer layer for the fourth layer. The last layer uses a thicker 3Z-T1 steel plate to make a composite armor plate."

This is actually the structure of the earliest composite armor target plate used in China. It actually appeared in the late 70s. At that time, it had already fallen behind the international advanced level. However, now it is definitely leading.

Mr. Guan pondered over Gao Zhendong's example and said, "Huh? Interesting, layered and complex, each with its own responsibilities."

Gao Zhendong shook his head. "It's not as simple as just doing their own job. Take 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. This will have a great impact on the stability of the jet."

"And I'm wondering if the whole set of composite armor plates, under the high-speed impact of metal jets or armor-piercing bullets, can have the effect of cutting off the jets or armor-piercing bullets due to the different speeds and directions of the violent movement."

When Mr. Guan heard this, he drew a picture on his notebook and thought about it carefully for a long time. After a long time, Mr. Guan looked up and was very happy: "That's the reason. Interesting, interesting. Although chromium-containing corundum (alumina ceramics) is difficult to burn, it is not impossible to make it. The weight of the entire armor plate will be greatly reduced compared to the average steel armor. As for the protective performance, we will know after doing experiments! But this theory sounds very feasible."

After thinking for a while, he smiled at Gao Zhendong and said, "Comrade Zhendong, you have thought about the structure and materials of the composite armor so clearly. I think you also have some ideas about the specific thickness of each layer, right?"

With Gao Zhendong's current achievements and status, he can directly use the term "genius mind" to explain some seemingly incredible ideas and technologies of unclear origin, especially in the field of materials.

So he didn't try to hide it and directly reported it: "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 is .mm. In this way, the thickness of a single armor plate is appropriate, and the weight is also controlled within the range that is convenient for human maintenance. According to my estimation, the ability of this kind of armor plate to resist armor-piercing and armor-piercing projectiles should be stronger than the average steel armor of the same thickness."

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 that to protect against armor-piercing projectiles, especially after the appearance of Armor Piercing Fin Stabilized Discarding Sabot (APFSDS).

Gao Zhendong did not calculate the thickness to the millimeter, as that would be too outrageous. Instead, he chose a number closest to 10. However, it did not have much impact on the performance and was even slightly better. The weight was just a little bit larger, which did not have much impact.

He directly gave General Guan the parameters of the composite armor, which could help them avoid detours and speed up their research progress. In fact, for this kind of armor plate, all they had to do was experiment.

In fact, Gao Zhendong also knows better composite armor structures, materials and processes, but those were things from the 90s. For now, the processing is too complicated, so we can only leave it for the future.

General Guan wrote down Gao Zhendong's entire design and was very happy: "Zhendong, if the test is successful, you will be the chief designer of this composite armor model, haha."

Gao Zhendong touched his head and said, "Hehe, that doesn't matter. In fact, I have another idea." Since they are already here, he might as well tell it all at once and give them a little shock.

Mr. Guan's eyes were dull. What? You still have ideas? Are you an idea machine that has turned into a spirit?
Mr. Guan reacted and turned another page in his notebook.

This time, Gao Zhendong took out the explosive reactive armor. In fact, this thing is not very suitable as the main armor, but it is very suitable for upgrading the protection capabilities of old equipment.

Gao Zhendong explained the principle, structure, and material selection of the explosive reactive armor to General Guan, and finally said: "The advantage of this type of armor is that it has the same anti-armor capability and is even lighter, but it also has disadvantages."

Mr. Guan was still shocked by Gao Zhendong's genius idea, and asked stupidly, "What are the shortcomings?"

He didn't even bother to think about it himself. Here's the genius. I should just ask directly.

　There is another chapter today.

　　The thickness of each layer of this composite armor target plate is actually now public and easy to find, but in order to avoid trouble, I still hide it. Please understand.

　　The units that produce tanks are not as simple as the Grassland Tractor Factory mentioned in the article, and the reason is the same as above.

　　I will not explain similar situations in the future in detail.
