Unlike small aircraft, composite component forming technology is the key to manufacturing large aircraft. Composite material is a new type of material composed of high-strength and high-stiffness reinforced materials laid in a matrix. It has a series of advantages such as high specific strength, high specific modulus, good fatigue resistance, good stealth, and corrosion resistance.
The use of composite materials in aircraft means that the structural 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 use carbon laminates for the fuselage and wings of commercial large aircraft, and can even replace aluminum alloy for skinning the fuselage!
In addition, carbon fiber composite materials can also be used in brake wheels, carbon brake discs and carbon disc anti-oxidation coatings.
It can be said that mastering large-area new carbon fiber composite material forming technology is the focus of material technology in aviation manufacturing!
The new materials research base of Hongxin Group has issued a new proposal to China Commercial Aircraft Company, hoping to take over the new carbon fiber composite material construction and forming technology research project.
Affiliated to China Commercial Aircraft Corporation, it is a composite materials research base.
This materials research base has a history of more than 20 years and has researched and manufactured aviation materials for a variety of small aircraft, fighter jets, rockets and other aviation machinery and equipment.
The main person in charge of the new carbon fiber composite molding technology research group, Gao Wei, is fifty-five years old. He is an expert in the chemical industry and a master in the field of materials research.
"Team Leader Gao, look, the company just issued a notice that Hongxin's first technical cooperation is with us!" A researcher handed the document notice to Gao Wei.
"Huh? They didn't go to the sensor and aviation system research group, but they actually came to us first?" Gao Wei was a little surprised. He knew that Hongxin Group was the world leader in sensor and intelligent system research, so he thought that Hongxin Group would focus on these first. Technical support in the field.
"I've also looked for it, but our research group is a priority for cooperation, and they attach great importance to material research and development." said the researcher.
"That's it." Gao Wei pondered for a moment and said, "That's fine, let's see what the strength of this legendary 'black technology manufacturing factory' Hongxin Group is!"

China Commercial Aircraft Company, reception room.
The current CEO Peng Zhengge is negotiating with representatives of several foreign companies, and the reason for the negotiations is also because of the requirements put forward by Hongxin.
"Mr. Peng," an American corporate executive of Indian descent said in strangely pronounced Chinese, "Our large-area carbon fiber composite materials are the best in the world. More than 50% of the world's commercial large aircraft are The body is made of carbon fiber composite materials produced by our company.”
"Not only you, but companies such as Boeing, Lockheed, and United Airlines are all using our carbon fiber composite materials. I don't understand why China Commercial Aircraft has suspended its purchase plan for carbon fiber composite materials?"
This man’s name is Anderson Fogus, and he is the general manager of Honeywell International’s China region.
Honeywell International Corporation of the United States is one of the world's top 500 technology companies. Its core businesses are aerospace, automotive and engineering materials, as well as industrial control technology and automation products.
One of the main technical partners of China Commercial Aircraft Company is Honeywell International. Many materials for the aircraft fuselage are provided by Honeywell International.
When Peng Zhengge and other management initially cooperated with Honeywell International, they wanted to obtain certain technical support from Honeywell International. Who would have known that these Americans are very shrewd and will always be careless when it comes to technology.
In the end, Huaxia Commercial Aircraft Company can only purchase their company's aviation materials at high prices for the manufacture of aircraft.
"Mr. Fogus, 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 other materials according to the purchase plan." Peng Zhengge did not say the reason.
However, Anderson Fogus himself speculated on the reason. He said directly: "As far as I know, you want to manufacture this new carbon fiber composite material through Hongxin Group, right?"
Peng Zhengge nodded and said, "This is also one of the reasons."
Anderson Fogus shook his head repeatedly and said: "I think this sounds like a very bad decision. Mr. Peng, I kindly advise you to give up this idea. The carbon fiber composite materials used in large aircraft manufacturing are dozens of our company's It has been continuously researched and improved for many years and has passed a number of international aviation standards, guaranteed by decades of safe aviation history.”
"First of all, as far as I know, there are almost no research laboratories on aerospace materials in the research field of Hongxin Group - if we count the small drones."
"This shows that they have no historical experience, professional researchers and technical reserves. Carbon fiber composite materials can be manufactured by some high-tech companies in the world, but they must be spread into a large-area carbon fiber composite material network to withstand aviation encounters. Problems such as high temperature, cold, rain corrosion, etc. are the biggest technical problems. "
"Aerospace is not a research toy. Once there is a problem with the materials, it means that your aircraft will encounter serious safety problems. This is a disaster for the aerospace company!"
Anderson Fogus strongly emphasized the technology and safety of Honeywell International. Peng Zhengge smiled and said: "Mr. Fogus, of course we understand this. It's just that the result may not be as bad as you said."
"No, no, no!" Anderson Foggs continued to deny, saying: "You should know that all materials of large aircraft must be tested by international airworthiness standards, otherwise they will not be allowed to be used on commercial aviation aircraft."
"Even if Hongxin Group can help you speed up the problem of large-area laying of carbon fiber composite materials, it is unknown whether it can be inspected and how long it will take. And your company's large aircraft order must be delivered within the specified time limit. To sum up, we at Honeywell International are your best partner!”
Anderson Foggs' words made Peng Zhengge hesitate, and what he said made sense. At least for now, their company continues to produce a batch of carbon fiber composite materials for aircraft production to deliver the aircraft order from AVIC International Leasing Co., Ltd. that was previously obtained at the Beijing International Air Show.
"Let's do this, Mr. Fogus. Our company still needs to make adjustments when it comes to the procurement plan. If you are not busy, you can wait until we finish discussing it before we discuss it." Peng Zhengge said.
"I'm not busy. I plan to stay here these few days and make some arrangements for other materials." Anderson Fugus didn't plan to leave until this order was completed.
