Chapter 643

"Aviation materials?" Schumann's face was even more dazed. Unexpectedly, Tengfei group also set foot in aviation materials.

"Nomex, Kevlar and T700!" Yodel sighed and said two proper nouns.

Schumann was stunned for a moment, and then widened his eyes. He opened his mouth a few times and wanted to say something, but he didn't know why. He moved his lips for a long time and couldn't say a word.

Nomex material is the name of DuPont company in the United States. It is called Aramid 1313 in China. In Tengfei group, it is called honeycomb aramid. Because of its light weight and strong toughness, it is generally used to make reinforced honeycomb structure, that is, the so-called aramid paper honeycomb composite.

In fixed wing aircraft, this material is generally used as the movable control surface of the wing, leading edge flap, aileron, hatch and other main structures.

Moreover, it is widely used in the main cabin structure of private aircraft and business aircraft, so as to reduce the total structure of the whole machine, enhance the air tightness of the aircraft, and reduce the cabin noise.

However, compared with large aircraft and private aircraft, the most widely used material is helicopter.

From the honeycomb of the main support structure in the helicopter rotor, to the composite material of the fuselage and cabin door for weight reduction, to the reinforced structure at the bottom of the fuselage for heat and cold insulation and anti damage, almost every key large part has the shadow of Nomex material.

Aside from that, this material is widely used in the "Black Hawk" helicopter made in the United States.

Kevlar material is also produced by DuPont in the United States. Its Chinese name is Kevlar, and its domestic name is Kevlar 1414. Tengfei group is more used to call it reinforced Kevlar.

Because the role of different brands of materials is not the same, some can be used as the main material of bulletproof vest or helmet, while some can bear the external strengthening protection layer of optical fiber. Only a few reinforced aramid fibers can be applied to the aviation field, as one of the basic reinforced materials, so as to improve the performance of the whole machine.

Among them, T700 is the most widely used carbon fiber composite.

However, whether it is Nomex, Kevlar or T700, each of them is the most cutting-edge aerospace materials in the world. Several times over the whole earth, only the United States and Japan can produce these three kinds of materials at the same time.

Even the Soviet Union, which claims that it has a very strong material capability, can't do it. As for Europe, although it has been working hard for so many years, it can't stand the dumping of such high-end aviation materials by the United States and Japan, resulting in the rapid collapse of the European industry, which can only be imported from the United States and Japan.

Of course, it's imported from the United States and Japan. In fact, it can only look at the face of the Americans, because Japan is also a tool man strangled by the Americans in its arrogance.

If the Americans want to make the Japanese get up, they can make Japan get up. If they want to see Japan surpass the United States, they don't have to look back and slap them in the face. Moreover, Japan can't have any temper, so they must bow to the American master politely and say thank you: "Sir, you slap me so much!"

Because of this, although in the international market, these three types of high-end aerospace materials are the related enterprises of Japan and the United States. It seems that the two sides are still fighting fiercely. In fact, all resources are in the hands of the Americans, forming a de facto monopoly.

Therefore, the high price of these three types of aerospace materials is outrageous.

Not to mention that, because of the important application of such materials in aviation and aerospace, the United States has also listed them on the list of strategic controls. In terms of exports, the United States has made a set of classification similar to fantasy novels, with one price for its core allies and another price for its peripheral allies. Friendly countries have a lot to say, and other countries may not be able to buy them even with more money The people of China are under direct embargo.

Therefore, one of these three types of materials can be counted as one in the international market. They are all sky high prices. Even if they start with the price of their core allies, they are too expensive to make people vomit blood.

However, the major aviation manufacturing giants in the United States vigorously promote and apply these materials, which not only makes the aircraft prices continue to rise and earn more profits, but also makes the costs of major aviation maintenance companies rise sharply.

That is why some airlines with poor strength, even if they buy a large airliner, will abandon it in a few years. They would rather buy a new one than try to repair the old one, because the cost of repairing the old one may be higher than that of buying a new one.

On the contrary, this has pushed up the sales of aircraft models of US aviation manufacturing giants.

People in other countries in the world are not idiots. Naturally, they can see that this is the absolute weapon for the United States to engage in monopoly, but they dare not to be angry. If you don't have this thing, how can you treat the Americans? It's cool to vent your temper. If you go back to the United States and give up your confession, you can beat your face and make you lie on the ground and call dad.

Hold your breath and engage in independent research and development?

It's a good choice, but before you can get it out, the Americans unite with Japan to start large-scale sales promotion activities. All kinds of discounts can make you doubt your life and let you produce as much as you want, until they consume you to death. Other people's materials have been upgraded, and the high prices continue to drive you to death.

Over the years, the European aviation industry, including Airbus, has been held by the Americans like eggs. They are stubborn and do not want to get down, but it is very difficult to stand up. They can only bow like shrimps and let the American aviation manufacturing giants slap in the face. One of the key reasons is this.Boeing and McDonnell Douglas both use these materials on a large scale to improve their performance. If Airbus does not use them, it will fall behind and be beaten if it falls behind. However, if they use them, the cost will be higher than that of Boeing and McDonnell Douglas. They can only maintain a balance carefully and torture European aviation engineers almost into mental illness.

Schumann, as a member of the European aviation industry, naturally knows the dilemma faced by Europe in this field. So when he heard that Tengfei group could produce these three kinds of materials, he was surprised. At the same time, he really understood why the two aviation maintenance giants were so eager to meet Zhuang Jianye.

It doesn't matter what the market is. If you can get low-cost high-end materials, that's the way to go. You should know that American aviation manufacturing giants are eating alone with the eggs of high-end materials, which has seriously affected the interests of these aviation maintenance giants.

It's cheaper to buy a new plane than to repair an old one. If it goes on, who will repair an old one and buy a new one? What will they do with the aviation maintenance business? Are you going to drink the northwest wind?

So no matter Donald Wayne or Moston, they don't care much about the market encroachment of Tengfei group. What they want is to get low-cost aviation materials, so as to reduce their own costs and survive better.

Realizing this, Schumann's blank eyes turned to Yodel's, and he said, "why don't you report such an important thing earlier?"

Yodel shrugged helplessly: "even if I report, do you think the bastards in the headquarters can believe it?"

Schuhmann's old face was red. When he did not hear it, he took a hand and uncovered the topic. Then he was somewhat impatient. "This plan has changed. Compared with seeking technical support, I hope to get the European agency of these three kinds of high-end materials."
