Silicon carbide stacking multi-layer graphene technology is a scientific research project that Mu Yang attaches great importance to, and is also a top priority in the materials project.

If the mass production problem of graphene is solved, its importance will be equal to the company's metal 3D additive process technology.

Graphene is of great significance to lightweighting.

Like Kongtian-1, if graphene can be applied on a large scale, the weight of the fuselage can be reduced by more than 30%.

Xinghai Group has metal 3D additive process technology that can fuse graphene into each layer of metal to create ultra-high-strength composite materials.

Just adding a trace (01mm) of graphene is equivalent to adding 5mm Q235B steel plate, and the toughness is better.

Like the Future 01 car, after a few strands of graphene are attached to the steel plates and tires of the car, it is equivalent to adding ultra-thick steel plates to the surface of the car.

If some graphene is thickened, anti-machine sniper rifles will not be able to deal with such bulletproof vehicles.

If soldiers put on such body armor, it would not be a problem to freely shuttle through the hail of bullets, as long as they are not shocked to death or hit in non-graphene covered parts.

That's why the use of graphene in the military is too abnormal, and the monarchy definitely doesn't want this type of material technology to be acquired by other countries.

Mu Yang came to the experimental building with anticipation and excitement, and saw the project leader, Dr. Chen Liu, already waiting for him at the entrance of the experimental building.

"Let's take a look at the real thing first." Mu Yang waved his hand directly and said.

"Okay, Chairman, we have trial-produced 10 kilograms, and the number of layers in mass production is more than 10. Our current problem is that the smaller the number of layers, the more unstable the production." Chen Liu walked behind Mu Yanglue, walking as he did.

explain.

"This is normal. The thickness of graphene is too thin. How many layers can it be stably produced now?"

"Twenty layers or more, but I recommend stacking a hundred layers. If the number of layers is too few, the process and equipment requirements will be relatively high when applied in industry, and the production cost will increase dramatically. After all, we have already made graphene

The cost has come down, and adding several times more layers won’t actually increase the weight much.”

Mu Yang nodded, understanding the problem he was talking about.

In the industrial world, the more precise it is, the more difficult it is to manufacture, or in other words, even super large things are difficult to manufacture.

Generally, the thickness of a piece of facial tissue is about 08-12 mm.

A piece of tissue paper is made up of 3-4 sheets of tissue paper, that is, the thickness of a piece of tissue paper is about 02-03 mm.

Today, the thickness of one hundred layers of graphene is about 0.02 mm, and it would take one thousand layers of graphene to be as thick as a thin piece of paper.

The thickness of one hundred layers is equivalent to the strength of 7 mm ordinary steel, and the thickness of some automobile sheet metal is only 8-1 mm.

If graphene is attached to shoes and clothes, they can prevent being punctured by sharp objects and be durable.

After a while, Chen Liu took Mu Yang to change into dust-proof clothes and then went to the clean laboratory after dust removal.

It is now July, and the weather in Jiangnan Province is extremely hot. Fortunately, the temperature in the clean laboratory is controlled at around 20 degrees Celsius. Mu Yang feels very cool when he walks in.

In Xinghai Group, even if cooling systems are installed in factories, the working environment of workers in most factories is only slightly different from the office environment.

The graphene laboratory covers an area of ​​two to three thousand square meters, and there are about a hundred scientific researchers responsible for this project. The scientific researchers passed by Mu Yang, stopped and bowed slightly to say hello, and then left.

Mu Yang came to a room of thirty square meters. There were some experimental equipment in the room, such as microscopes and macro and micro observation equipment.

"This is a 20-layer sheet, 50 centimeters long and 50 centimeters wide. It is cut. We can produce it with a width up to 5 meters and no limit to the length."

Chen Liu pointed to the glass surface next to a microscope and said.

Mu Yang took a look and felt like he didn't see anything.

If you look closely, you can see a thin layer of gray and transparent sheets spread on the glass, with the four corners pressed by four plastic blocks.

Graphene itself is black, but if it is extremely thin and its structure is a hexagonal mesh, photons can pass through it, so it looks transparent.

Hold the graphene between your thumb and index finger, rub it gently and find that it is very elastic.

"Have the mechanical properties test and chemical composition been done?" Mu Yang asked.

Chen Liu replied: "We have done it, and it has met the design requirements required by you, Chairman. Now we have to solve how to apply it to products, which is also a big problem." When they developed the equipment for mass production of graphene,

, everyone is very excited, they know very well what this means.

In practical applications, graphene is best used in combination with other materials, rather than as a pure graphene material.

For example, fiberglass is a composite material that is mixed with glass fiber and resin, then cured and processed. The glass fiber provides strength and stiffness, while the resin provides resistance to chemical corrosion, heat resistance and plasticity.

If graphene replaces resin, it will become super fiberglass. Since there are not many graphene layers, this composite material still has transparent properties.

But how to mix them together is also a technical problem, and the technical problems of mixing different materials are also different.

In front of Mu Yang, Chen Liu had something to say and did not dare to hide it.

"Well, let's first find a way to mix it into titanium alloys and put it on space suits. Let's solve the aerospace problems first." Mu Yang thought briefly, "However, we will set up a separate graphene application department, and your department will focus on graphene research.

Just use ene. There is no need to focus on studying the application. It is not easy to do one thing well, so pay attention to confidentiality."

"Ok, I see."

Mu Yang thought for a moment, then called Zhou Chen and Wang Hai and asked them to come over.

After waiting for more than ten minutes, the two finally arrived.

Mu Yang summoned the core members of the graphene project team, plus Zhou Chen and Wang Hai, to a conference room. He solemnly said:

"Graphene has been successfully developed, and the next step is to apply it.

Being able to mass produce means that the material world will change, but it will also bring endless troubles. In the next few years, we will not announce its existence to the outside world, including relevant department personnel.

You organize reliable personnel to form an application department and find ways to apply it to multiple types of materials. Everyone must pay attention to confidentiality."

Everyone saw that the chairman took it so seriously and didn't even plan to report it to the relevant departments, so they probably understood what he meant.

Graphene, when used well, is a weapon of war, no less than the birth of Moguyun.

Like the company's aerospace plane, it's so big that it can't be hidden as long as it's in use.

As for the material graphene, as long as no one tells it, no one will know that Xinghai Group has developed it.

Like the graphene project members, they also know that the company has many secrets that they do not know. They cannot enter other laboratories of the company, and colleagues from other laboratories cannot enter their laboratories.

Xinghai Group is so big, with more than 150,000 formal employees, and most employees don't know what scientific research projects the group has.

Many laboratories are not named after the research subjects. For example, the Graphene Project Laboratory named it "Black Web Laboratory". When outsiders see this laboratory, they think it is engaged in network information.

Moreover, the detailed information of scientific researchers in each laboratory is confidential and cannot be inquired at will.

The meeting ended in a while. Mu Yang only needed to outline the general direction, and the management below would formulate specific plans.

At two o'clock in the afternoon,

After Mu Yang took a lunch break, he received a report from Han Li. At the Xingyue Base, scientific researchers had completed the module transportation work, and Kongtian-1 was returning to Earth.

The company is producing its second aerospace plane, which is customized by relevant departments. Xinghai Group has asked for a friendly price of 20 billion yuan.

Of course, the price of an aerospace plane is more than that. The price is over hundreds of billions of dollars, and some developed countries want it.

For these countries that develop aerospace aircraft, it is priceless. It is a black technology product. Hua State prohibits its sale to them, and even those with money cannot buy it.

Muyang decided to develop Kongtian-2, using graphene materials on a large scale.

At half past five in the afternoon, the company got off work.

At this time, the sun has not yet set, and the outdoor temperature is still over 30 degrees. Employees are staying in the office to blow on the air conditioner, and don't want to go home.

Mu Yang continued to blow on the air conditioner and drink tea in the office. Zhou Chen didn't go back either. After seeing him, he came in to drink tea and chat with him.

There are also iced drinks in the office, but Mu Yang prefers to drink less of them. Drinking too much is not good for your health. If you can, drink as little as possible.

"Someone at the subdistrict office is so shameless. They dug and rebuilt a good road. They are crazy and don't even look at what's going on here."

"Will it affect the traffic of our company's trucks?" Mu Yang knew what Zhou Chen was talking about. In some places, heating pipes are repaired in winter and water pipes are repaired in rainy days. He is not surprised to see such bad things happen often.

"There must be some influence. It's not a human affairs matter. I called Zhang Wei directly yesterday to criticize them. It's not a human affairs matter. Zhang Wei didn't know about it. He immediately sent someone to investigate. He gave me a reply in the morning and it has been dealt with.

I sent someone to approve the road and said that the road will be restored to its original state within three days." Zhou Chen said with a half-smile, he had a lot of experience, and his secretary reported this to him.

"The environment is much better now, but it is inevitable that there are still rat droppings. We can't control this kind of thing, we can only give feedback." Mu Yang Ruo pointed out that he didn't want to deal with such nonsense.

"I got it."

Zhou Chen talked to the chairman about the international situation. Xinghai Group is building a base on the moon. This is no longer a company's business, but a major international event. It even threatens some countries. How can Xinghai Group threaten them?

.

Now whenever we talk about Xinghai Group, it is an international incident.

But Mu Yang and Zhou Chen just don't go abroad and don't participate in disputes in that area. They just like to do whatever they want and can't control Xinghai Group. However, Xinghai Group can in turn control these countries and use various top technologies on them.

The road to cutting-edge technology in these countries is blocked, and it is difficult to bypass the technology patents of Xinghai Group.
