Miss Leihart, who had been holding back her energy, heard Bao Zixuan's roll call. She thought that it was finally her turn, and she 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 not convinced 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. I am very happy to work with you. I hope this cooperation will not

Let me down."

No one expected that this female engineer would be so arrogant. German women are really tough. At this time, everyone was curious to see what this woman was capable of. She actually dared to say that. But since they can participate in this seminar

, no one dares to look down upon you. Bao Zixuan doesn’t care about anything, and there is no way he would 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 incoming projectiles, consumes their energy, and ultimately prevents projectiles from penetrating. This type 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 each layer of armor-piercing or armor-piercing bullets consumes a certain amount of energy. Due to the different hardness of the materials in each layer, the core of the armor-piercing bullet or the metal jet of the armor-piercing bullet can change the direction, and even the core of the armor-piercing bullet can be changed.

Break. Therefore, the anti-penetration ability 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 rather than simply thickening the armor to improve protection. To some extent, it has also enabled tanks to transform from the lethality of anti-tank weapons.

He came out under 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 use of composite armor. It has nothing to do with cognition, but is mainly concerned about the excessive weight of the vehicle body.

There have always been different 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. They believe this 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 k8 composite armor?"

We are all smart people, and we must have some confidence when others dare to bring it up. No one is so stupid that they directly question other people's scientific research materials without seeing anything.

Mia von Lehardt: "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 of the warhead. Finally, it loses its polarity.

When most of the energy of the armor-piercing bullet hits the high-tenacity inner base plate, it has no armor-piercing ability. This is the wonderful use of the "sandwich biscuit".

Everyone is surprised to hear this. As a vehicle manufacturing engineer, of course I know about ceramic composite armor, and many people have seen the British "Chopham" ceramic composite material. It can block armor-piercing projectiles fired by a 120 mm caliber cannon at a distance of 2,000 meters.

.

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

Bao Zixuan: "Dr. Leihart, how is this k8 ceramic composite material different from others?"

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

Mia von Reinhardt thought to herself that there are things you don’t know. Haven’t you always considered yourself a genius before? This is the perfect opportunity for Bao Zixuan to see the capabilities and technical strength of German engineers.

In terms of titanium alloys, Bao Zixuan is the absolute authority, and in terms of aluminum alloys, it is slightly worse; but everyone basically understands it, after all, these two materials are mainly used in the aviation field. As for other alloy materials, they just turn a blind eye and do not understand them at all. After all,

I didn’t graduate in a related field, and I didn’t have much in-depth contact with it in my previous life.

Mia von Leihart: "The K8 ceramic composite material is improved on the basis of tank armor. Compared with the ceramic composite armor materials 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 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. When developing materials, they had considered large-scale applications and were very targeted.

40 rocket launcher is definitely famous. People always refer to ak-47, rpg rocket launcher and 107 mm rocket launcher as the three artifacts of guerrilla warfare in the world. Among them, rpg rocket launcher generally refers to the rpg-7 40 mm 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 need to

How to solve it, please ask Dr. Leihart to give the answer."

Hearing this, Mia von Leihart thought to herself, Bao Zixuan is very accurate in seeing the problem. Although he is not a student of basic materials, he has a wide range of knowledge. Fortunately, he was prepared in advance, otherwise he would be embarrassed.

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, you don’t have to worry at all.”

Since there is no problem with processing and the performance is so superior, all that remains is the price. 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 will really have no way to survive. Although the U.S. military is rich and wealthy, it is not 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 leads the research and development of k8 materials, which are designed to replace ordinary alloy materials. The price is really not expensive, at least most companies can accept it.

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

After hearing this, Bao Zixuan is quite satisfied; at least the price is acceptable. Time is tight, and at this time, I can only trust the Germans. With how rigorous they are in treating technology, they should not do anything fraudulent.
