Chapter 272 Application Bottleneck of Carbon Fiber
As for material technology, Wu Hao is an outsider, but Gu Fan is a half-expert. It is necessary to consult with him.

Wu Hao called Gu Fan to the office.

"Gu Fan, do you know anything about the related products of graphene, a new material?" Wu Hao asked tentatively.

"You have to specify which aspect it is, whether it is electrical and thermal conductivity, or strength, or flexible and foldable electronic products. Graphene is used in a wide range of fields and cannot be generalized." Gu Fan is obviously much more professional.

"Applications in terms of strength, such as weight reduction of the car body, such as thermoforming various mechanical structures, such as the production of aviation turbine blades, electric ducted jet engines, and the like." Wu Hao gave a range.

"That is the processing technology of composite aviation materials, as well as the processing technology of body components. In this respect, graphene materials are not used much at present, and they are used in high-end bicycle frames. Now only carbon fiber is used in car frames, and the weight reduction is also important. It’s only a few hundred kilograms, and the processing cost is extremely expensive. In terms of composite aviation materials, there are more high-strength carbon fibers, and almost none use graphene. At the same time, they also face the problem of difficult processing. I am not optimistic about this market.”

Gu Fan knows about this aspect, but he doesn't understand the specific details, because he has never been in contact with related industries. After all, these industries are relatively cutting-edge, especially aviation materials, which are not something ordinary people can get involved in.

"Why is the processing of the frame expensive? Tell me the reason. I want to know about the graphene material project, which requires some industry knowledge." Wu Hao said.

"Wu Hao, don't you have any new ideas? I found that every October, you would come up with some strange ideas, and you would not give up if you didn't achieve your goals. Although you can succeed every time, you will develop Open up a new field, but if you want to touch graphene, a new material, I will not support you!"

Gu Fan immediately became vigilant. Although Wu Hao's previous ideas were outrageous in the eyes of ordinary people, they were still in the field of ordinary civilian use. Although they were whimsical ideas, they were still achievable.

This time Wu Hao suddenly expressed his interest in graphene, a new type of material, which is far beyond the scope of ordinary civilian use. In this high-tech material application field, huge losses will occur if one is not careful.

"Calm down! Just chat like an ordinary person, don't be so nervous." Wu Hao had thoughts in this regard, but he didn't dare to reveal it immediately. After all, he needed to research two key things first.

"Okay, let me just say it briefly."

"Weight reduction is an eternal topic in the automotive and aerospace fields. In order to pursue faster speed, more stable cornering, and more precise control, weight reduction design and craftsmanship have always been the ultimate pursuit of engineers. .Compared with traditional materials, carbon fiber materials have many advantages, but carbon fiber materials have not been popularized.”

"First of all, it is expensive. The price of high-strength carbon fiber T1000 is more than a thousand yuan per kilogram. Even if a frame is only a few hundred kilograms, it will cost 10,000+, which is simply unaffordable for ordinary users."

"Secondly, it may not be available for purchase. High-strength carbon fiber materials have always been monopolized by several companies. The production technology is now concentrated in the hands of Neon Country. Domestic manufacturers are now slowly rising, but the output and quality still need to continue to work hard."

"Then, the harshness of the carbon fiber material processing environment and process further increases production costs."

"For example, if the carbon fiber cloth is bonded with dust, its strength will decrease, so the carbon fiber construction molding room is a dust-free, constant temperature and humidity environment, and a constant difference in indoor and outdoor atmospheric pressure. A workshop like this is comparable to most Compared with ordinary factory buildings, the cost is so high."

"Furthermore, in the process of carbon cloth bonding, in order to ensure high precision between groups, pure manual grinding, robotic arm gluing, and pure manual bonding are used. Once there are more pure manual processes in the production process, time costs and manpower will be reduced. The cost will go up."

"The construction of low-temperature baking molding requires painting, and carbon fiber components require different painting processes than metal components, and the process is more complicated."

“Before painting, all welds and exposed positions need to be sealed with sealant, and then damping glue is used to seal after the sealing step is completed. After the sealing is completed, the entire structure will be polished by hand, and the structure will be polished with sandpaper It becomes a frosted surface, so that there is no reflection and no bottom exposed."

"After the sanding is completed, there are 4 layers of lacquer, all painted by hand, followed by primer, mid-coat, base coat and varnish."

"The whole process requires a lot of labor, the output is low, the degree of automation is difficult to improve, and the cost performance is not high."

"In the aviation industry, through the integrated forming technology, these shortcomings are not obvious, and the cost can be digested. After all, the profits of the aviation industry are there, but in the field of automobile manufacturing, every penny must be paid attention to. When digging, this material can only be used in high-end cars with very few production volumes, either F1 racing cars, limited-edition sports cars, or super luxury cars used by the boss.”

Gu Fan introduced the industrial status of new carbon fiber materials in one breath. His meaning is very simple, this muddy water is very deep, don't rush into it like a fool.

"Oh, so that's the case, what about graphene? In real life, I don't seem to have seen many applications. It was reported before that this is a new type of material with high strength, and it has very good applications in many aspects. Prospect." Wu Hao roughly understood the application bottleneck of carbon materials, and began to ask about the situation of graphene. At this time, he needed to collect more data to complete the tasks given by the system.

"The performance of graphene is excellent, but that is the data on paper. Some properties can only be possessed by very perfect graphene. In the existing preparation process, such requirements cannot be met."

"For example, the electrical and thermal conductivity is quite good, but a large current graphene will burn; the thermal conductivity is excellent, and it becomes no different from the thermal conductivity of graphite once laminated; the transparent electrical conductivity is amazing, and even several The company claims that it has mass-produced graphene touch screen mobile phones, however, the price is not comparable to OLED, and the durability is also worrying.”

"The relatively mature applications now have actual production applications in lubricating oil, conductive inks, and anti-corrosion coatings. In other areas, the production process needs to be further improved to obtain a larger area of ​​single-layer graphene before it can be applied. .”

Gu Fan mentioned the current situation of the graphene industry. It has a future, but under the current technical conditions, there are no mature products. It is just an illusion that people think it is awesome.
