Chapter 412

Zhuang Jianye pulled out his face for a moment. He did not expect that the snakeskin bag contained the most cutting-edge aircraft manufacturing materials in the world aviation field, honeycomb sandwich structure components.

He quickly and carefully picked it up from his desk, opened the snake skin bag, and took out a metal plate about 20 cm thick, the size of a washbasin.

Although you can feel that it is made of metal and the thickness is considerable, the overall weight is very light, even lighter than the real enamel basin.

Two palms clamped the plate and squeezed it inward. As a result, Zhuang Jianye made a lot of effort. The light plate on his hand was not damaged, not to mention the slightest deformation.

Zhuang Jianye nodded with satisfaction, and then put the honeycomb component on the table again. Then he asked song Yanan, "did the forest worker see it? What do you say? "

Not to mention that Lin Guanghua is OK, song Yanan complained angrily: "what else can I say? I still think the cost is too high. Let me try to continue to reduce the cost. I have replaced the two sides of the plate from t500c carbon fiber composite material with relatively cheap aluminum lithium alloy. The cost has been reduced by one third. He is not satisfied. If I reduce it again, I can only reduce the cost The composite material of aramid paper honeycomb is changed into aluminum honeycomb, which can be reduced by half

After hearing this, Zhuang Jianye also had a headache.

If the structure and materials of the old yun-5 continue to be used in the improved yun-5, the range and carrying capacity will be reduced.

This is a disaster for the improved yun-5.

Therefore, how to achieve leapfrog performance improvement without affecting the original flight quality of the improved Y5 is an unavoidable problem for Tengfei aviation manufacturing corporation.

If we put it in other aviation manufacturing enterprises, we will be blind. We should know that safe and reliable lightweight aviation materials are much more difficult than pressurized cabin.

Even if this enterprise can get relevant technology from other channels, it is very troublesome to do it, because a new material involves too many things.

First of all, it's a problem to make; second, it's a variety of analysis of new materials to see if other materials on hand can match the new materials; second, it's an attempt in various aspects of technology to see if the existing equipment is suitable for the processing of new materials; and then

Anyway, all kinds of things are complicated and boring. It's hard to fully understand the properties of new materials in two or three years. It's really moving to make such progress.

However, other factories can not solve the hard bone, Tengfei head office, this alternative enterprise in the supercharged cabin, has no difficulty.

The reason is that the aviation technology R & D center has been established for many years.

Although the name sounds frightening, in fact, this R & D center mainly does one thing, that is, the preparation, production and terminal processing of carbon fiber composite materials and all kinds of aviation materials derived from it.

Starting from the imitation of T300 composite materials provided by Toray company of Japan, Tengfei aviation technology research and development center first improved the processing technology of T300 composite materials, and then successfully imitated t500 carbon fiber composite materials provided by H company.

On the basis of these two kinds of composite materials, Tengfei aviation technology R & D center continues to explore carbon fiber composite materials with higher performance. At the same time, it also develops several derivative material projects of composite materials.

One of them is the aerial stealth material that even the Qin Red Army did not know much about.

This is a kind of fiber braiding method for radar wave mirror effect that song Yanan accidentally discovered when he was developing the subsequent reinforced version of t500 carbon fiber composite.

At that time, song Yanan didn't think much about it. It was just an experiment. It was far away from a higher level of carbon fiber composites. Therefore, he took it as a daily experiment and reported it to Zhuang Jianye in the form of a briefing.

At a glance, Zhuang Jianye knew that this was a great thing. While increasing investment, he actively contacted the army, hoping to share some pressure in terms of funding.

Although the troops are also short of funds, they feel that the materials that can be used for radar stealth are of great military significance. In addition, Tengfei factory will share the research and development expenses, so they do not hesitate to agree.

As a result, the originally unimportant R & D center of Tengfei aviation technology has become even more unimportant.

So that in addition to Zhuang Jianye and several other core executives of take-off airlines, the general staff are not clear what this organization does.

As for the stealth materials, even fewer people know about it, and only Zhuang Jianye knows about the top management of the whole head office.

Of course, stealth materials are only one aspect, and there are many other derivatives, among which the composite honeycomb sandwich structure is the most practical one.

As early as when T300 carbon fiber composite was put into production, song Yanan and others began to try composite honeycomb sandwich structure. However, at that time, the strength of T300 carbon fiber composite was average, and the internal sandwich had defects, so there was no large-scale application.

Only by changing to t500 composite, the aramid paper honeycomb based on composite material has also made a breakthrough, which can complete the second generation of carbon fiber composite honeycomb structure.But at this time, Tengfei factory is undergoing three transformations. It's very happy to fight with H company abroad, and it's also hard to fight with all kinds of big men in China. In addition, the aramid paper honeycomb based on composite materials newly produced by Tengfei aviation technology research and development center is not mature and has insufficient production capacity, so it's not over soon.

It was not until March this year that song Yanan and others developed t500c carbon fiber composite with more excellent performance, and solved the stability and production capacity of aramid paper honeycomb based on composite materials, and the third generation of carbon fiber composite honeycomb components had use value.

It was just at this time that Tengfei factory began its fourth transformation, and officially entered the development of manned aircraft. The third generation of carbon fiber composite honeycomb components coincided with the meeting, and could be applied to the improved yun-5.

However, the good news didn't make Zhuang Jianye and others happy for long. They were almost crying because of the cost reported by song Yanan. There's no way. The cost of carbon fiber composite is too expensive.

Although the price is not as exaggerated as gold, it is not far away from this level.

If this is just for the sake of witnessing a miracle, it's just for someone to make a debut regardless of cost, which is the peak. The problem is that the improved Yun 5 of Tengfei factory has to be put into the market to make a small profit.

Good quality and low price is the positioning of the improved Yun 5. It's like luxury jewelry. Few people can afford it. What kind of money can they earn?

You know, China is not rich enough to spend a lot of money, so it is imperative to cut costs.

So there is a simplified honeycomb component on the desk, which is made of aluminum lithium alloy and composite aramid paper.
