Unlike small aircraft, composite component forming technology is key to building large aircraft. Composite material is a new type of material composed of high-strength and high-stiffness reinforced materials laid in the matrix, which 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 is that the carbon laminate of the fuselage and wing parts of commercial large aircraft can be used, and the fuselage can even be skinned instead of aluminum alloy!

In addition, carbon fiber composites can also be used in brake wheels, carbon brake discs and carbon disc anti-oxidation coatings.

It can be said that mastering the large-area new carbon fiber composite forming technology is the focus of material technology in aviation manufacturing!

Hongxin Group's new material research base has issued a new proposal to Huaxia Commercial Aircraft Company, hoping to take over the research project of new carbon fiber composite material construction and forming technology.

Huaxia Commercial Aircraft Co., Ltd., 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, 55 years old this year, is an expert in the field of chemical industry and a master in the field of materials research.

"Team Leader Gao, you see, just now the notice issued by the company, the first technical cooperation on the side of Hongxin, has found us!" a researcher handed the document notice to Gao Wei.

Gao Wei was a little surprised, he knew that Hongxin Group was a world leader in sensor and intelligent system research, and thought that Hongxin Group would focus on technical support in these fields first.

"I also looked for it, but our research group is a priority cooperation level, and they attach great importance to material research and development. The researcher said.

"That's it. Gao Wei pondered for a moment or two and said: "That's okay, let's see what strength this legendary 'black technology manufacturing factory's Hongxin Group has!"

......

Huaxia Commercial Aircraft Company, reception room.

The current CEO, Peng Zhengge, is negotiating with representatives of several foreign companies, and the reason for the negotiation is also because of the requirements put forward by Hongxin.

"Mr. Peng. An American business executive of Indian descent said in oddly pronounced Mandarin, "Our large-area carbon fiber composite materials are among the best in the world." More than 50% of the world's large commercial aircraft use our carbon fiber composite materials on the fuselage. ”

"It's not just you, Boeing, Lockheed, United Airlines, these companies are using our carbon fiber composites. I don't understand, why Huaxia Commercial Aircraft is suspending the purchase plan of carbon fiber composite materials?"

This person's name is Anderson Fergus, and he is the general manager of Honeywell International in China.

Honeywell International Inc., one of the world's top 500 technology companies, has core business in aerospace, automotive and engineering materials, as well as industrial control technology and automation products.

One of the main technical partners of Huaxia Commercial Aircraft Company is Honeywell International, and many of the materials for the aircraft fuselage are provided by Honeywell International.

At the beginning, Peng Zhengge and other management cooperated with Honeywell International in the hope of obtaining some technical support from Honeywell International. Who knows that these Yankees are very shrewd, and when it comes to technical aspects, they are all sloppy.

In the end, Huaxia Commercial Aircraft Company could only purchase its aviation materials at a high price for the manufacture of aircraft.

"Mr. Fergus, regarding the purchase of carbon fiber composite materials, our company has encountered some problems, so we have to suspend the procurement plan, but we will still purchase other materials according to the procurement plan. Peng Zhengge did not say why.

However, Anderson Fergus himself speculated the reason, and he said directly: "As far as I know, you want to make this new carbon fiber composite material through Hongxin Group, right?"

Peng Zhengge nodded and said, "This is also one of the reasons. ”

Anderson Fergus shook his head and said, "I think it's a decision that sounds terrible. Mr. Peng, I kindly advise you to dispel this idea. Carbon fiber composite materials used in the manufacture of large aircraft are the technology that our company has been researching and improving for decades. It has passed a number of international aviation standards and has decades of safe aviation history as a guarantee. ”

"First of all, as far as I know, there are almost no research laboratories on aviation materials in the research field of Hongxin Group - if that small drone is counted. ”

"This shows that they have no historical experience, no professional researchers and no technical reserves. Carbon fiber composite materials can be manufactured by some high-tech enterprises in the world, but it is the biggest technical problem to lay it into a large-area carbon fiber composite network, which can resist the problems of high temperature, cold, rain and corrosion encountered in aviation. ”

"Aerospace is not a research toy, and if there is a problem with the material, it means that your aircraft will have serious safety problems. This is a disaster for the aviation aircraft company!"

Anderson Fergus strongly emphasized the technology and safety of Honeywell International, and Peng Zhengge smiled: "Mr. Fergus, of course we understand this. It's just that the results aren't necessarily as bad as you say. ”

"No, no, no!" Anderson Fergus continued, saying, "You should know that all materials for large aircraft must be inspected according to international airworthiness standards, otherwise they will not be allowed to be used in commercial airlines. ”

"Even if Hongxin Group can help you accelerate the large-scale laying of carbon fiber composite materials, it is unknown whether it can be tested and how much time it will take. Your company's large aircraft orders are to be delivered within the specified deadline. In summary, we at Honeywell International are your best partner!"

Anderson Fergus's words made Peng Zhengge hesitate, and what he said also had some truth. At least for now, the company continues to produce a batch of carbon fiber composite materials for the delivery of the aircraft order from AVIC International Leasing Co., Ltd., which was previously received at the Beijing International Air Show.

"So be it, Mr. Fergus. When purchasing the plan, our company also needs to adjust. If you're not busy, you can wait until we're done talking. Peng Zhengge said.

"I'm not busy, I'm going to stay here for the next few days and make some arrangements for other materials. "Anderson Fergus doesn't plan to leave until this order is finalized.
