Different from small aircraft, composite material forming technology is the key to manufacturing large aircraft. Composite material is a new type of material made up of high strength and high stiffness reinforced material laid in the matrix. It has a series of advantages such as high specific strength, high specific modulus, good fatigue resistance, good stealth, corrosion resistance and a series of advantages.
Using composite material in aircraft means that the weight of the aircraft can be significantly reduced and the performance of the aircraft can be improved. The carbon fiber composite material proposed by Hong Xiaoxiao can be used to replace the carbon laminate in the fuselage and wings of commercial large aircraft. It can even replace aluminum alloy as the skin of the fuselage!
Other than that, carbon fiber composite material can also be used in the anti-oxidation coating of brake wheels, carbon brake discs and carbon discs.
It can be said that mastering the large scale new carbon fiber composite material forming technology is the key material technology in the aerospace manufacturing industry!
Hongxin Group's new material research base issued a new proposal to Huaxia Commercial Aircraft Corporation. They hope to take over the new carbon fiber composite material forming technology research project.
Huaxia Commercial Aircraft Corporation's composite material research base.
This material research base has a history of more than 20 years. It has researched and manufactured many kinds of aviation materials for many types of small aircraft, fighter jets, rockets and other aviation machinery equipment.
The person in charge of the new carbon fiber composite material forming technology research team, Gao Wei, 55 years old this year. He is an expert in the field of chemistry and a big name in the field of materials research.
"Leader Gao, look, the company just issued a notice. Hongxin Group's first technical cooperation came to us!" A researcher handed a document to Gao Wei.
"Huh? They didn't look for the sensor and aviation system research team but came to us first? " Gao Wei was a little surprised. He knew that Hongxin Group is the world leader in sensor and AI system research. He thought that Hongxin Group will focus on technical support in these areas first.
"They also looked for us, but our research team is the priority level. They put a lot of emphasis on materials research." The researcher said.
"I see." Gao Wei thought for a while and said, "That's good. Let's see what this legendary 'black technology factory' Hongxin Group has!"
…
Huaxia Commercial Aircraft Corporation's reception room.
The current CEO, Peng Zhengge, was negotiating with a few foreign company representatives. The reason for the negotiation was also because of Hongxin's request.
"President Peng." A Native American company executive said with a strange Chinese accent, "Our large scale carbon fiber composite material is the best in the world. More than 50% of commercial aircraft in the world use our company's carbon fiber composite material for the fuselage. "
"It's not just you. Boeing, Lockheed, and United Airlines are all using our carbon fiber composite materials. I don't understand why China's commercial aircraft suspended the purchase of carbon fiber composite materials. "
This person's name was Anderson Forges, and he was the head of the China region of Honeywell International.
Honeywell International Corporation of the United States, one of the top 500 technology companies in the world. Its core business is aerospace, automotive, and engineering materials. It also includes industrial control technology and automation products.
One of China Commercial Aircraft Corporation's main technical partners is Honeywell International. Many of the materials for the aircraft's body are provided by Honeywell International.
Back then, Peng Zhengge and the rest of the management had cooperated with Honeywell International in order to obtain a certain amount of technical support from the company. Who would have thought that these Americans were so shrewd? Whenever it came to technology, they would play dumb.
In the end, the Huaxia Commercial Aircraft Company could only purchase their aviation materials at a high price for the aircraft manufacturing.
"Mr. Forges, regarding the purchase of carbon fiber composite materials, our company has encountered some problems, so we have to suspend the purchase plan. However, we will still purchase the other materials according to the purchase plan." Peng Zhengge didn't say the reason.
However, Anderson Forges speculated the reason himself. He directly said, "As far as I know, you want to use Hongxin to manufacture this new type of carbon fiber composite material, right?"
Peng Zhengge nodded and said, "This is also one of the reasons."
Anderson Forges shook his head repeatedly and said, "I think this is a terrible decision. President Peng, I advise you to give up on this idea. The carbon fiber composite material used for large aircraft manufacturing is a technology that our company has continuously researched and improved for decades. Moreover, it has passed many international aviation standards and has decades of safe aviation history as a guarantee. "
"First of all, as far as I know, Hongxin's research field has almost no research laboratories on aviation materials — — if that little drone counts."
"This means that they have no historical experience, and no professional researchers and technical reserves. Some international high-tech companies can manufacture carbon fiber composite materials, but the biggest technical problem is to lay it into a large carbon fiber composite web that can withstand the high temperature, cold, rain corrosion and other problems encountered in aviation. "
"Aviation is not a research toy. Once there is a problem with the material, it means that your aircraft will encounter serious safety problems. This is a disaster for the airline company! "
Anderson Forges strongly emphasized the technology and safety of Honeywell International. Peng Zhengge smiled and said, "Mr. Forges, of course we understand this. But the result may not be as bad as you say. "
"No, no, no!" Anderson Forges continued to deny. He said, "You should know that all the materials for large aircraft must be tested according to international airworthiness standards. Otherwise, they will not be allowed to be used on commercial aircraft."
"Even if Hongxin can help you speed up the issue of large scale carbon fiber composite laying, it is unknown whether it can pass the test and how long it will take. And your company's large aircraft order has to be delivered within a specified time limit. To sum up, Honeywell International is your best partner! "
Anderson Forges's words made Peng Zhengge hesitate. What he said had a certain degree of truth. At least for now, their company continued to produce a batch of carbon fiber composite materials for aircraft production to fulfill the aircraft order from Air China International Leasing Limited at the Beijing International Air Show.
"How about this, Mr. Forges. Our company still needs to adjust the purchase plan. If you are not busy, you can wait for us to finish the discussion. "Peng Zhengge said.
"No, I plan to stay here for a few days and make some arrangements for other materials." Anderson Forges did not plan to leave before this order was completed.
