Chapter 668

Professor Ali Khan's shock is not hypocrisy.

He knows about metal matrix composites. The simple thing is to use special fibers to strengthen metal materials. However, generally speaking, this kind of special fiber has strong performance and can make metal materials fly by.

For example, boron fiber, graphite fiber, carbon fiber, silicon carbide fiber and so on.

However, among many fibers, few people use glass fiber to strengthen metal materials. It's not that they haven't tried. The key is that the material characteristics of glass fiber are too general. Even if it is strengthened into the metal, the improvement effect on the metal is not very good, or even not as good as those alloy materials with good metallurgical technology.

Because of this, in many fiber-reinforced materials, glass fiber is quickly eliminated, so that up to now, it can only be combined with epoxy resin to make glass fiber material similar to FRP, which can be used in the non load bearing structure of aircraft interior.

However, Tengfei group not only combines glass fiber with aluminum to create a new super hybrid composite material no less than aluminum lithium alloy, but also has lighter weight and lower cost.

What this means is that Professor Ali Khan, who has worked in the aviation giant for half his life, knows too well.

as like as two peas, Professor Ali Khan is very puzzled. Even if glass fiber is low in cost, he can want to melt fiber into aluminum, the process should be similar to other reinforced fibers in metal, and the process complexity is almost the same. The only area is that glass fiber is different from other reinforcing fibers, so the time of processing is very long. Different.

However, the cost of the process is negligible.

Among other things, the most critical vacuum pressure furnace in the preparation of this kind of materials costs tens of thousands of US dollars at a time, and even tens of thousands of US dollars for a slightly larger one.

That's all. In order to ensure the quality of materials, the amount of materials prepared at one time should not be too much. If we share it like this, without mentioning the value of the materials themselves, the process cost will be very high. This is just a vacuum pressure furnace, and there are more than one kind of equipment in the whole process of fiber reinforced materials, at least more than ten.

Because of the complexity of the preparation process, although the fiber-reinforced composite can be industrialized, the output is always not up. If the output is not up, the cost can not be diluted. If the cost can not be shared equally, the price will be expensive.

Therefore, the internal logic of the high cost of composite materials is not a gimmick, but the inevitable result of its complex process and low production capacity. Otherwise, composite materials are so good, how dare the major giants not let go? No way. It's too expensive.

But Tengfei group's super hybrid composite materials even make the cost of ordinary aluminum alloy. How did they do it?

If other people don't turn the horn, such as Rahman and Zarif, they don't understand the materials, and they don't care how they do it.

As long as the cost is good and the performance is not bad, that's a good thing.

Anyway, they come to investigate the situation of the plane, not to learn how to build the plane. Why do they think so much? exhausted or not!

But Professor Ali Khan is different. He resigned from an aviation giant like Boeing and returned to Pakistan with great ambition to help Pakistan develop its aviation industry. Therefore, when he encounters problems that he can't understand, he wants to get to the bottom of the matter.

So after being surprised, Professor Ali Khan said to Zhuang Jianye and Lin Guanghua, "Mr. Zhuang, Mr. Lin, I'm very curious about the preparation of your ultra hybrid composites, I don't know..."

As a result, before Professor Ali Khan finished speaking, Zhuang Jianye put his hand on it and laughed with indifference: "if you want to see the production of this kind of material, other materials may be troublesome, but super hybrid composite materials are OK. No.7 workshop next to you produces this kind of material."

"Mr. Zhuang, is that true?" Professor Ali Khan couldn't believe his ears. He looked at Zhuang Jianye with a pair of eyes just like ox eyes.

We should know that the production process of materials is very important in any country. Although it does not reach the level of complete confidentiality, it is not easy to show to others under normal circumstances.

Professor Ali Khan is very clear about this. If not, he would not be able to use the word "curiosity" to test it. How could he think that Zhuang Jianye was so generous and agreed to it without hesitation.

Professor Ali Khan can't be surprised.

Zhuang Jianye looked at Professor Ali Khan, who had won the five million lottery prize. He said with a smile: "other people don't have this treatment, but you are guests from Pakistan. We and you are iron brothers.

There is an old Chinese saying that one family does not speak two languages. Since they are brothers, they have to do everything in their power. Otherwise, what are they called brothers? Don't say you want to see it, but if you want to take it back, our Tengfei group will pack it up and help you to pack it up and send it by mail. What's there to hide? Let's see, old fellow iron... Bah Dear old brothers, workshop 7 starts... "

What Zhuang Jianye said is full of pride. If the Pakistani military delegation moves the whole Xiping factory back the next moment, it won't frown. Brother, is it brother without such courage?The wrinkles on Professor Ali Khan's face trembled, and he said that the friendship between China and Pakistan will last forever. The Chinese people are really the most reliable friends of Pakistanis.

Rahman and Zarif agreed with each other excitedly. However, compared with Professor Ali Khan's simple gratitude, their thoughts are much more complicated. However, they are relieved. They thought Zhuang Jianye was a ghost, but they didn't expect that they were also a generous master. Instead of some high hats, they began to be poor and generous.

But it's also good. If they like anything in the back, they want it directly. It's all brothers!

Only Lin Guanghua took two puffs from the corners of his mouth. After that, these Pakistanis were fooled and lamed by Lao Zhuang. The whole family didn't speak two words, and then there were brothers to settle the accounts.

What is a brother, you have to do everything, but these Pakistan's iron Hans are not clear about the object of the knife is to pay attention to, with Lao Zhuang's urine, it's easy to get others!

Sure enough, when all the people came to workshop 7, the members of the Pakistan military delegation, including Professor Ali Khan, were shocked by the whole set of ultra hybrid material production equipment in front of them. When they were speechless, they heard Zhuang Jianye wave his hand to those equipment and said with high spirit: "we spent 220 million US dollars on the construction of this set of ultra hybrid composite material production equipment, If you want to, I won't say anything. Give me a half discount, make up the whole, and take all the $100 million! "
