"Uncle, you can't joke like that. I came to ask you if any rockets have used carbon fiber materials, and if so, which manufacturer makes them?"
"Your car also uses carbon fiber?"
Seeing Xing Baohua nod, his father-in-law said, "Go to Jilin City in the Northeast. There is a polyacrylonitrile research institute there."
They used carbon fiber production equipment and related testing instruments imported from Daying, achieving the localization of high-performance carbon fiber and breaking through related technologies. However, as far as I know, their products still lag far behind those of advanced countries.
Xing Baohua laughed and said, "No matter how big the gap is, as long as we have it, that's fine. I can't get those advanced materials. The Japanese have already sent people over, saying they have no stock. DuPont doesn't have any either. Damn it, I think they just don't want to sell to me!"
"Good to know. You have to rely on yourself for everything," the father-in-law replied.
"Oh dear, I forgot to tell you something. Didn't you tell me last time that you suggested using array antennas for motorcycles? I went to talk to their manager about it a while ago, and it took a lot of effort to get them to agree to change the plan." After Xing Baohua finished speaking, he wanted to see if his father-in-law was a little excited, but unfortunately, he didn't show any expression.
"Okay, not bad." He then smiled slightly.
"I've completed the mission. Can you tell me what the purpose was?" Xing Baohua asked like a curious cat.
"Some things are better left unsaid; knowing too much will keep you up at night!" With this reminder, Xing Baohua suddenly realized that it was indeed better not to ask questions that shouldn't be asked.
However, Xing Baohua's father-in-law still offered him a favor, saying that if he encountered any difficulties, he would try his best to help through his former employer.
This promise was probably conveyed to Xing Baohua through his father-in-law, and the relevant department owes Xing Baohua a favor.
Xing Baohua returned to the temporary office at the car factory from his father-in-law's place and arranged for someone to go to Jishi to deal with carbon fiber.
Carbon fiber is only one part of the outer shell; it needs to be bonded with other materials, which involves composite materials.
As a heavy industrial city, central Shandong also has several large chemical plants.
Among them, Luzhong No.1 Plastics is responsible for researching the resin composite material used for the outer shell, which will be used to bond carbon fiber.
Sports cars have very loud large-displacement engines, which requires soundproofing and fireproofing/heat insulation layers to be applied to the car body.
Initially, rock wool was considered, but Overeich rejected this, proposing instead the use of expanded aluminum.
Made of metal, it is not only soundproof and fireproof, but also lightweight and can be shaped using a hydraulic press.
The dense mesh-like space formed by foamed aluminum can effectively absorb kinetic energy.
In other words, it can absorb force after a collision.
Wei Laisong contacted Luzhong Aluminum Plant, and the chemical departments of No. 1 Plastics, No. 2 Plastics, and Luzhong Petrochemical cooperated in the research and development of foamed aluminum, a new type of material.
Look at how a car factory drives many downstream industrial chains.
Of the car builders that Shen Jie invited, only two came.
Upon seeing that it was about building sports cars, he simply said he didn't know how and left.
Since we can't get them to come, let's just keep making things delicious!
With ZF's chassis and transmission in place, the three basic components were complete.
It uses a DMC chassis, an AMG engine, and a ZF transmission.
With the basic preparations complete, installation and debugging began. Since it was now being handcrafted, the experienced master craftsmen also offered some advice.
Overrecht and his team also made the outer shell clay based on the appearance drawn by Xing Baohua.
This is equivalent to the shape of a mold, used for data processing.
The people from Lao Cao's glass factory came. But Lao Cao didn't come. Xing Baohua asked where Lao Cao had gone and learned that he was abroad on business and hadn't returned.
The clay model wasn't ready yet, so Xing Baohua asked the glass factory's sales representative to wait two days for the data to come out. He wanted to check the design first, and if they could make it, Xing Baohua would place an order.
The salesman from Lao Cao Glass Factory also patted his chest and said that there was no glass that their factory couldn't make.
Xing Baohua believed him. Old Cao's glass factory supplied glass to many car manufacturers around the world.
While the prototype was being prepared, Overeich presented Xing Baohua with a difficult problem.
"Xing, the car needs wind tunnel testing, so you need to book the testing site in advance."
Xing Baohua countered, "Cars also need wind tunnel testing."
Overrecht shrugged and said, "Of course. All Mercedes models need wind tunnel testing; I only make changes based on their experiments."
But we're a large, reputable manufacturer now, and we need the relevant tests and data. Without wind tunnel testing data, the cars we produce have a very high risk factor. They also wouldn't pass the safety certifications in Europe and America. So you can only sell cars domestically?
Xing Baohua didn't expect that getting a car would be so troublesome later on. But what Overeich said was right. If the certification of European and American systems is not recognized, how can he earn foreign exchange?
Which company has a professional wind tunnel laboratory?
“I knew Mercedes had one, and they’re currently the world’s largest. We can use theirs initially, but later on, I hope we can have our own,” Overecht said.
“Okay, I’ll inquire about it,” Xing Baohua nodded in response.
Our country doesn't yet have a professional wind tunnel testing facility for automobiles. However, we do have wind tunnels, but those are used for aircraft testing.
I just don't know if it can be used in cars.
Left with no other option, Xing Baohua went to see his father-in-law again.
"You're going to build a wind tunnel testing ground? I mean, you don't really want to add a booster to your car, do you?" Xing Baohua's father-in-law asked in surprise.
"I just heard that cars also need to go through wind tunnel testing. We don't have that in China, do we? Cars need to undergo rigorous testing after they are manufactured, otherwise they can't get international certification and won't be able to sell."
