Reborn in Hong Kong: The Tycoon Grows Up

Miss Leihart, who had been holding back her energy, heard Bao Zixuan's roll call. I thought that it was finally my turn, and I must let the Americans see that they were able to win World War II not because of advanced technology and good basic materials. It's just that it has more advantages in terms of strategy, and it has nothing to do with personal ability or the technical strength of the company. Many people were unconvinced by Germany's defeat, especially engineers.

Mia von Leyhardt stood up and said: "Hello everyone, I am Mia von Leyhardt, Ph.D. in materials science; from Thyssen AG. It is a pleasure to work with you, and I hope this cooperation will not it disappointed me."

No one expected that this female engineer would be so arrogant. German women are really tough. At this time, everyone was curious and wanted to see what this woman was capable of; how dare she say this. However, since they can participate in this seminar, no one dares to look down upon it. Bao Zixuan doesn't care about anything. He won't let you in if he doesn't have the ability.

Mia von Leyhardt continued: "Based on the technical requirements of this military vehicle, Thyssen and Krupp decided to use K8 composite armor."

Composite armor is non-homogeneous tank armor composed of two or more layers of protective materials with different properties. Generally speaking, it is composed of one or several materials with different physical properties, compounded according to a certain layer ratio. Depending on the relationship between each layer The difference in physical properties between the projectiles interferes with the penetration of the incoming projectile, consumes its energy, and ultimately achieves the purpose of preventing the projectile from penetrating. This kind of armor is divided into three types: metal-metal composite armor, metal-non-metal composite armor, and spaced armor. They all have strong comprehensive protective properties.

Composite armor has multiple layers, and armor-piercing or armor-piercing bullets consume a certain amount of energy each time they penetrate one layer. Due to the different hardness of each layer of material, the core of the armor-piercing projectile or the metal jet of the armor-piercing projectile can be changed in direction, or even the core of the armor-piercing projectile can be broken. Therefore, the penetration resistance of composite armor is much higher than that of homogeneous armor. When the weight per unit area of ​​the armor is the same, the ability of composite armor to resist armor-piercing projectiles is twice as high as that of homogeneous steel armor.

The emergence of composite armor is a revolution in the history of tank protection technology. Its birth has led tanks to rely on new material technology instead of simply thickening armor to improve protection. To some extent, it has also made tanks less lethal than anti-tank weapons. He came out under the threat and regained the throne of the king of land warfare. It is no exaggeration to say that composite armor saved the tank as a weapon.

Many people are still skeptical about the ability to use composite armor. It has nothing to do with cognition. The main concern is that the weight of the car body is too heavy.

There have always been differing opinions on what materials to use. American engineers still hope to use traditional metal materials; special alloy materials with high strength and toughness. But German engineers insist on using composite armor materials, which they believe is an inevitable trend in the future development of military vehicles.

Special steel cannot effectively resist attacks, and composite armor can perfectly deal with direct attacks from bullets and small artillery shells.

David Bruce, the head of the assembly, asked directly: "Dr. Leihart, we have discussed this before. Composite armor materials are high in cost, complex to process, and most importantly, too heavy. It is difficult to meet the US military's requirements for new military vehicles. , is there anything different about the K8 composite armor?"

We are all smart people, so if someone dares to bring it up, they must have some confidence. No one is so stupid as to directly question other people’s scientific research materials without seeing anything.

Mia von Reinhardt: "K8 armor is the latest new ceramic composite armor successfully developed by Thyssen Company."

The structure of ceramic composite armor is similar to that of cream sandwich biscuits. The panel layer is made of very hard alloy steel, the base layer is made of very tough alloy steel, and the middle layer is composed of many small ceramic balls. The gaps between the balls are filled with glass. Fiber reinforced resin.

When a menacing armor-piercing bullet passes through the layer of the "sandwich biscuit", the warhead has become blunt and consumes a lot of energy. Then, the stronger ceramic balls in the middle layer decompose and dissipate the main impact force of the warhead. Finally, when the armor-piercing projectile that has lost most of its energy hits the high-tenacity inner base plate, it has no armor-piercing ability. This is the magic of "sandwich cookies".

It's incredible for everyone to hear this, as a vehicle manufacturing engineer. Of course, we know about ceramic composite armor, and many people have seen the British "Chopham" ceramic composite material. That can block an armor-piercing projectile fired by a 120mm cannon at a distance of 2,000 meters.

However, the weight and thickness of ceramic composite materials are simply not suitable for use as ordinary military vehicles. After all, the thickness of the tank is not comparable to that of ordinary vehicles.

Bao Zixuan: "Dr. Leihart, is there any difference between this K8 ceramic composite material and others!"

I don’t want my subordinates to ask questions at this time, and many people don’t dare to ask more questions. After all, constantly asking questions means ignorance. They don’t want to expose their weaknesses in front of their boss, especially when outsiders are around.

Mia von Reinhardt thought there is something you don’t know. Didn’t you always think you were a genius before? We can take advantage of this opportunity to let Bao Zixuan see the capabilities and technical strength of German engineers.

Bao Zixuan is the absolute authority when it comes to titanium alloys, and slightly less so when it comes to aluminum alloys; but everyone basically understands it, after all, these two materials are mainly used in the aviation field. As for other alloy materials, I just have a blank look and don't understand them at all. After all, I didn't graduate in a related field, and I didn't have much contact with them in my previous life.

Mia von Leihart: "K8 ceramic composite material is improved on the basis of tank armor. Compared with the ceramic composite armor material used in traditional tanks, it is lighter in weight and thinner."

"Although the corresponding anti-strike capability is weaker, it can fully meet the technical requirements of the US military for new military vehicles."

"Only 2 centimeters of K8 ceramic composite armor is needed to withstand direct attacks from 40mm caliber artillery. To be precise, it is designed for the Soviet 40 rocket launcher, which can definitely increase the survivability of the crew on the battlefield."

Hearing this, Bao Zixuan felt that the Germans had put in some effort. The materials were developed with large-scale applications in mind and are very targeted.

40 rocket launcher is definitely famous. People always refer to AK-47, RPG rocket launcher and 107mm rocket launcher as the three artifacts of guerrilla warfare in the world. The RPG rocket launcher generally refers to the RPG-7 40mm rocket launcher produced by the Soviet Union.

As a classic weapon produced by the Soviet Union, its structural principle is very simple and is very suitable for large-scale use.

The power device of the 40 rocket consists of two parts: the tail tube propellant and the main engine. The rocket launcher adopts a pinprick firing mechanism. The six small holes at the tail are the nozzle holes of the main engine. The rocket has a ignition hole at the bottom of the engine nozzle. It is equipped with detonating powder, and there is a positioning latch on the missile body. There is a positioning gap at the front end of the rocket launcher. When loading, the positioning latch of the rocket is inserted into the positioning gap of the barrel, and the firing pin of the firing mechanism can be used to aim. Ignition hole.

Bao Zixuan was still a little worried, so he asked directly: "Ceramic materials and metal materials have high hardness and low density. However, their tensile capacity is small, which means that armored ceramics cannot withstand large bending stress. Some special parts require How to solve it, please ask Dr. Leihart to give the answer.”

Hearing this, Mia von Leihart thought to herself that Bao Zixuan was very accurate in seeing the problem. Although I am not a person who studies basic materials, my knowledge is quite broad. Fortunately, I was prepared in advance, otherwise it would be embarrassing.

Mia von Lehardt said with a smile: "Mr. Bao's words are very reasonable. Ceramic materials do have this problem. However, ThyssenKong has developed a tough backsheet, which is designed to solve this problem. I think. You can process any shape of K8 composite armor, no need to worry at all.”

Since there is no problem with processing and the performance is so superior, only the price remains. As long as the price is reasonable, it should not be a big problem when it comes to cars.

Bao Zixuan: "What about the material cost? The price is too high and it is difficult to promote it."

Good materials mean rarity, otherwise other manufacturers would really have no way to survive. Although the U.S. military is wealthy, it is not that easy to fool. Taxpayers are always watching them, and they dare not do anything too much.

Regarding the cost of materials, Mia von Lehardt has absolute confidence. She led the research and development of K8 material to replace ordinary alloy materials. The price is really not expensive, at least most companies can accept it.

Mia von Lehardt: "The material cost is equivalent to that of ordinary special alloys, and the cost of the two materials is within 10 points."

I am quite satisfied with Bao Zixuan after hearing this; at least the price is acceptable. Time is running out, and we can only trust the Germans at this time. With the rigor with which they treat technology, they should not do anything fraudulent.
