    ¡°The cost of composite materials is low?¡±

    After Professor Ali Khan listened to Lin Guanghua's words, his slightly cloudy gray eyes under his square glasses subconsciously narrowed. Without any other words, just such a repetitive question already showed the meaning without reservation.  come out.

    As for the members of the Pakistani military delegation such as Rahman and Zarif, at this time, they all set their sights on the people of Ascendas Group. They were like X-rays, eager to see clearly the hearts, livers, spleens, stomachs and kidneys of Zhuang Jianye, Lin Guanghua and others.

    How can something as advanced as composite materials be low-cost?

    That thing is completely representative of the cutting-edge technology. The direction of future technological development. If it is not expensive, how can it be worthy of high-end? There are actually low-cost ones. Is your Ascendas Group bullying us because Pakistan is ignorant? Where are you fooling the devil?

    Lin Guanghua had already guessed the reaction of Professor Ali Khan and others. He turned his head and looked at Zhuang Jianye beside him. Zhuang Jianye nodded. Lin Guanghua showed a knowing smile and immediately shouted to a workshop worker not far away.  : "Xiao Gao, bring two boards over here."

    "OK!"

    Seeing that it was Chief Engineer Lin who called him, Xiao Gao quickly responded and then took two keyboard-sized metal plates from his processing table.

    Lin Guanghua took it in his hand, padded it and handed it to Professor Ali Khan: "Professor, look at this."

    Professor Ali Khan took the plate in his hand. The plate was very thin, about 1.5mm thick. It exuded a metallic luster. It was light and airy in his hand, but it looked nothing special.

    "This seems to be an ordinary aluminum alloy material. I can't tell the specifics now, but judging from my experience, it must be aluminum alloy." After looking carefully for a long time, Professor Ali Khan finally came to a conclusion.  .

    Lin Guanghua smiled and without saying anything, handed the other piece to Professor Ali Khan again: "Professor, look at this."

    Professor Ali Khan took another metal plate of the same size into his hand. The next moment his wrinkled face suddenly shook, and he immediately looked up at Lin Guanghua with a face full of disbelief: "How is this possible?"

    No wonder Professor Ali Khan was like this, because the moment he bought the second plate, he clearly felt that the weight of the two plates of the same size was obviously different. The first one was much lighter than the second one.

    It was obvious that the first plate that he judged to be an ordinary aluminum alloy was a specially treated lightweight aviation metal material, and the second plate was a real aluminum alloy.

    As a veteran of aviation technology who has worked in giant manufacturers such as Lockheed, Airbus, and Boeing for half his life, he may not be familiar with other metal materials, but if aluminum alloy, the most widely used material in aviation manufacturers, cannot  It would be embarrassing to know.

    The result was good, I hunted geese all day long, and still got pecked in the eye by the geese.

    "The second piece is an aluminum-lithium alloy, and the first piece is our newly developed super-hybrid composite material. It is not only 15% lighter than ordinary aluminum-lithium alloys, but is also stronger than aluminum-lithium alloys in terms of material strength and fatigue resistance.  It¡¯s 2% to 5% higher.¡±

    Just when Professor Ali Khan was trapped in the shadow of misjudgment and couldn't extricate himself, Lin Guanghua's words slowly came and penetrated into his ears. However, Professor Ali Khan did not completely come back to his senses until Lin Guanghua's next words.  , Professor Ali Khan immediately felt as if he had been baptized by divine oil. He began to tremble inexplicably, so much that his eyes almost bulged out.

    ¡°Of course the most critical thing is the cost of this material, which is on average about two-thirds of that of aluminum-lithium alloy, which is basically the same as the cost of slightly better ordinary aluminum alloys.¡±

    "How can it be?"

    This time Professor Ali Khan was not incredulous because of his wrong judgment, he was truly shocked.

    Professor Ali Khan has not seen composite materials before, but has used them himself. He is very aware of the complexity of the technology and the difficulty of preparation. Otherwise, the cost of composite materials would not be so high.

    But the so-called ultra-hybrid composite material in front of us is not much better than the commonly used aviation high-end aluminum alloy in terms of performance. At most, it is only a little lighter.

    But the core thing in the field of aviation manufacturing is the weight reduction of aircraft. 1% lighter is a major improvement, not to mention that ultra-hybrid composite materials are 15% lighter. Not to say it is disruptive, it also creates a new field.

    You must know that the weight reduction effect of aircraft using this material will be very obvious, and the improvement in efficiency will be even more obvious.

    The cost of such high-quality materials has to reach sky-high prices, and the result is almost the same as slightly better aluminum alloy.

    Professor Ali Khan only feels that?The aeronautical materials science system that has been in Europe and the United States for half a lifetime has collapsed. It feels like I have entered a dream and I don¡¯t know what year it is today.

    "Mr. Lin, are you kidding? It is 15% lighter than aluminum-lithium alloy, and the material properties are 2% to 5% better, but the cost is only two-thirds of the latter. How can this sound like a dream?  Same."

    I don¡¯t know how long it took for Professor Ali Khan to finally come to his senses. Although his dark face was still trembling, he did not say anything perfunctory or prevaricating because of face or anything else, but spoke out his true feelings.  .

    Lin Guanghua nodded: "To be honest, when we were developing the Haidongqing A-type, I felt the same as you when we got this super-hybrid composite material. I never expected that a composite material would be so cheap.  , but this really happened, and it took me a long time to get used to it."

    "Then how did you do it?" Professor Ali Khan asked curiously.

    "It's very simple. We just replaced the aramid fiber in the aramid-reinforced aluminum matrix composite material with lower-cost glass fiber, and then we have this kind of material with the same properties as aluminum alloy material, but lighter in quality.  Low-cost composites.¡±

    When Lin Guanghua said this, he had a smile on his face, but he was filled with emotions in his heart.

    In fact, this ultra-hybrid composite material is one of the many fiber-reinforced metal matrix composite materials at the Ascendas Aviation Technology R&D Center. It was experimented many years ago. However, this low-cost material was not mature at the time. It can only be said to be aluminum.  It's just an alternative variant of alloy.

    Until Zhuang Jianye found out that the cost was not in place when he reviewed the Haidongqing project, if the unit price of mass production would exceed that of Yun8, who would buy it then.

    So we ordered to turn around the house and use all available means to reduce costs. At this time, the Ascendas Aviation Technology R&D Center found this glass fiber reinforced aluminum matrix composite material in its own technology accumulation.

    Then using the latest metal matrix composite material production technology, the weight of the material is greatly reduced, and the cost is extremely controlled.

    But Lin Guanghua naturally couldn't tell Professor Ali Khan these details, but even so, Professor Ali Khan opened his mouth in surprise: "Oh my God, glass fiber and aluminum, oh, it's really unimaginable, these two materials combined  Together they have such an amazing effect!¡±
