Chapter 722 Northwest Coal Chemical Plant
Yang Dongsheng has always wanted to get involved in the carbon fiber industry.

The use of carbon fiber is too great, rocket manufacturing needs, aircraft manufacturing needs, wind power needs!
Not to mention others, but his own drones will definitely need carbon fiber in the future.

However, the current international carbon fiber production and research and development are highly concentrated in the hands of a few companies in Japan and the United States, and manufacturers are highly concentrated in North America, Europe, and Japan.

Japan, in particular, holds the world's top carbon fiber production technology and occupies more than half of the world's carbon fiber production capacity.

In 1971, Toray began to produce T300 carbon fiber, but until more than 30 years later, we still cannot get T300 carbon fiber.

The reason is very simple. Until the past two years, when Yang Dongsheng was investigating in China, there was no laboratory in China that could produce T300 grade carbon fiber.

It usually takes five to ten years for a product to be researched in the laboratory to find out the production process in the factory.

According to the data, Toray had already developed the T1967 in 300, and it only took four years to figure out the production process, which is considered fast.

This is not the end yet. The factory still needs to continuously improve the production process and increase the yield rate. It will take several years to stabilize production.

However, our laboratory has not achieved T300 carbon fiber in the past two years, so one can imagine how big the gap is!

In the past few years, the coal and iron ore markets were not good, and Yang Dongsheng devoted all his efforts to public relations about semiconductor-related technologies, and he did not have extra funds and experience to devote himself to carbon fiber, so this matter was temporarily shelved.

I didn't expect Vice President Zhao to keep his heart!

"Get in the car and talk!" Yang Dongsheng winked at Vice President Zhao.

It wasn't until the car drove out of the campus that Yang Dongsheng asked, "Are the eyebrows you're talking about domestic or foreign?"

Carbon fiber is different from semiconductors. The United States has not suppressed Japanese carbon fiber companies in the same way it treats the semiconductor industry.

At this time, the world's annual carbon fiber production is only [-] to [-] tons, and there are only a few manufacturers that can produce it.

Not to mention running over to engage in production technology and poaching researchers, even if you want to steal a kilogram of samples and bring them back to China for research, the police will probably surround you as soon as the transaction is completed.

If it's from abroad, Yang Dongsheng is very worried that Vice President Zhao will be caught in the fishing law enforcement!

Fishing law enforcement is legal in the Anglo-American legal system. Vice President Zhao has no experience of living abroad, so he doesn't know about it!

Vice President Zhao said, "Domestic! The Northwest Coal Chemical Institute has successfully conquered the T300-grade carbon fiber related technology not long ago, and is currently researching the T700-grade carbon fiber!"

T300 and T700 are the carbon fiber product grades of Toray Corporation in Japan.

Toray is the leading carbon fiber production giant in the world. It not only masters the world's most advanced carbon fiber production technology, but also accounts for [-]% of the world's carbon fiber production.

Many companies in the industry are used to taking Toray's product brand as the standard, and based on their own product test results, they can figure out what level their products have reached.

"Northwest Coal Chemical Plant?" Yang Dongsheng recited silently.

Yang Dongsheng knew about this research institute located in Jinyang, the capital of Jin Province, which is a research institute under the Academy of Sciences.

In 1976, they built the first PAN-based carbon fiber expansion test production line in China, and the carbon fiber produced was named high-strength type I.

Although it is still only a test production line, the high-strength type I carbon fiber is not as good as T300, but it has successfully narrowed the gap between carbon fiber technology and the international advanced level to about 10 years.

"Is it PAN-based, viscose-based, or asphalt-based?" Yang Dongsheng asked.

The first step in carbon fiber manufacturing is to select raw materials. PAN base, viscose base, and pitch base refer to three different raw materials for manufacturing carbon fibers. These are also the three main research directions on carbon fibers in the world.

PAN is polyacrylonitrile. Many people may be confused by this name, but polyacrylonitrile has a common name called "artificial wool".

Those cheap wool sweaters and wool coats on the market are actually made of polyacrylonitrile.

Viscose-based carbon fiber is a carbon fiber made from natural fibers such as wood, hemp and cotton.

The bitumen base is simply bitumen, and both petroleum pitch and coal pitch are fine.

The difference of raw materials directly affects the final performance of carbon fiber!

"Their main research direction is PAN-based carbon fiber. The T300 grade carbon fiber that has been researched so far is PAN-based, and pitch-based carbon fiber is also researched, but it has not been successful yet!" Zhao Vice President said.

Yang Dongsheng nodded.

Due to its advantages in production, PAN-based carbon fiber accounts for more than 90% of the world's total carbon fiber production.

Toray mainly produces PAN-based carbon fiber.

However, viscose-based and pitch-based carbon fibers also have their own advantages and have not been completely abandoned.

Viscose-based carbon fiber is made of natural materials, no catalyst is used in the production process, and it does not contain metal ions. It is an ideal material for artificial joints and wound protection cloth.

At the same time, due to the low degree of graphitization of viscose-based carbon fiber and low thermal conductivity, it can be used to manufacture the heat insulation layer of the satellite return cabin.

The pitch-based carbon fiber has a higher modulus than the other two carbon fibers. Simply put, the material is less prone to deformation after molding, and is suitable for rocket engine nozzles, windmill blades and other fields.

Of course, this is not absolute. Toray has made high-modulus M40 and M50 carbon fibers on the basis of PAN-based raw silk.

Toray's daring to do this is due to their years of technology accumulation. Let's honestly do a good job of asphalt-based high-modulus carbon fiber first!

"Ask someone to book a train ticket to Jinyang, let's go and see!" Yang Dongsheng couldn't wait for the private jet to apply for the route.

"This..." Vice President Zhao hesitated and said, "We have already called them here!"

"Really?" Yang Dongsheng was slightly taken aback, "You can arrange it right away. I'll meet them. Where is the hotel?"

For such high-tech talents, Yang Dongsheng naturally had to show due respect.

"The place to live has been arranged!" Vice President Zhao hesitated, "It's just that there is still one problem that has not been resolved yet!"

"What's the problem?" Yang Dongsheng was stunned for a moment, and then he immediately reacted. He patted Vice President Zhao on the shoulder and said, "Don't worry, if the carbon fiber can be made this time, it will be placed under the banner of our northern branch."

Over the years, Yang Dongsheng has been continuously appropriating funds from Dongsheng Mining to Dongsheng Semiconductor, Dongsheng Heavy Industry and other companies, which made Dongsheng Mining dissatisfied.

The prosperity of the South Branch investing in Dongsheng Technology's development has stimulated Vice President Zhao's desire to strive for strength.

For this kind of healthy competition, Yang Dongsheng is encouraging!
"No, not this!" Vice President Zhao quickly waved his hands, "They want the house!"
