Chapter 120

"The point to be emphasized here is that this sample is only a sample, and it is defective, which you will find in the process of testing. Therefore, he can only provide you with an idea. Our goal is to develop stealth coatings far beyond its performance, rather than simply copy them! Do you understand? "

Everyone nodded. Hearing what the boss said, we had a basic understanding of the source of this sample. There are only a few countries in the world that can develop stealth materials. The boss means that the material is defective, so we all know its origin.

We should know that the intelligence quotient that can work here is not low. The boss of domestic stealthy materials is absolutely unable to get them. Even if they do, they will not be so blatantly taken out to do research for you. It is unlikely that the iron emperor's country will come from the United States. In our hearts, as long as the capitalist countries give enough money, some things will still go black The market flows out. It is estimated that the boss got it from which black market channel.

"Boss, here is a question I want to ask. This sample is in powder form. What kind of adhesive is used for coating? Do you have a sample of adhesive? It is also very important to our research! " Asked one of the experts, shaking the jar in his hand.

Lei Tiantang was stunned for a moment, then patted his forehead and said, "if you don't say I forgot, there is a sample of this adhesive. I thought it was ordinary glue, so I didn't pay attention to it. You should study it first and I'll take it now!"

That is to say, but Lei Tiantang even made the powder samples of stealth coatings. He was also negligent. He thought that as long as there were materials, he didn't pay too much attention to how to paint on the plane. Now it seems that the role of the adhesive is not small.

Fortunately, it's not too late to know. It's good to make a copy from the new one. Anyway, he has all kinds of basic materials in his storage space, so he doesn't have to look for materials now. After leaving the laboratory, he took some time to copy the adhesive.

Although there may be something wrong with the board, there is no problem with the basic material composition. It is enough to make samples, because what he copied is decomposed from the aircraft which has been painted dry, so it is still a little different from what it looks like before painting, but there are all the ingredients that should be included. Just try to find out which component is the dissolving agent.

After returning to the laboratory and handing them the adhesive, all kinds of testing work can finally be carried out. To tell you the truth, Lei Tiantang is also very curious about this material. Although he has learned a lot of material science knowledge in this period of time, they are all knowledge from books, and they are certainly not the most advanced knowledge. Therefore, he is very interested in the process of the experiment, so he did not leave the laboratory.

Zhao Junxian and various experts got together to discuss their respective division of labor, and then each with their own researchers began to carry out a variety of performance testing of samples.

With the development of the experiment, the test results of some items will come out about lunch time. First of all, the results of the composition. After the research and detection of the powder, we are more sure that these samples are from the United States, because its composition is very consistent with the results obtained from public information.

The conductivity of silver metal is very strong, and the resistance is only 1.59 × 10-8 Ω· m at room temperature. This conductivity can perfectly guarantee the electromagnetic radiation circulating in the aircraft body, and there is no need to worry about the current. As a metal, silver is very soft, and can be easily broken into various shapes by hand. Liquid pure silver can be easily made into various shapes, while silver can be easily made into various shapes It is difficult to react with other metals and materials because of its inactive chemical properties. Undoubtedly, it is the most suitable metal material for stealth fighter coating.

The content of silver in the powder accounts for a large proportion, which is basically the same as the material on the stealth coating used by F22 stealth fighter, but the silver content is not more than one fifth, otherwise its weight will not be so light. After all, the self weight of the fighter is also related to its combat effectiveness. If the metal composition of the stealth coating is too much, the stealth fighter will be coated Its weight will increase significantly, which has a great impact on its bomb load, and its combat effectiveness will also shrink.

The other components are mainly some organic polymer resin composite materials, which are very small in weight, and the special material composition can also well absorb radar waves, so it accounts for the largest proportion. Of course, there are some other inorganic additives.

The specific situation of the adhesive has also been roughly analyzed. The experts in charge of the research also mixed it with the right additives, and then mixed the powder of a can of stealth coating. After the overall blending, the coating was applied to the detection plate.

The advantages of Lei Tiantang's wealth and boldness are finally shown. He purchased all the equipment required by experts all the way. Therefore, the laboratory equipment is very complete now. Therefore, the laboratory has all kinds of equipment for testing the stealth coating of the finished product. There is no need to wait. The test can be carried out immediately after the coating is dry.

We didn't have a rest at noon. We went to the canteen to have dinner, and then we came back to continue to carry out various tests. We had such good conditions and opportunities to contact such high-level experimental objects. If these experts and researchers were not for Lei Tiantang's words to let us go to dinner together, they would probably not want to eat.When testing the finished coating, in addition to the people who are busy with their hands, the rest of the people waiting for the test results of the equipment all gather around to find out what the performance of this stealth coating looks like at the first time.

As the experimental equipment sends out various detection waves, various sensors connected to the plate behind the coating will display all kinds of data in real time. Everyone is shocked by the number displayed on the computer in real time. All of us are knowledgeable, and the data can be seen clearly.

At room temperature, the performance of stealth coating is very excellent. The onlookers also gave out a variety of low voice exclamations. It is the first time that we have come into contact with such a top-level material. We admire its performance very much. We must know that if we want to develop such a top-level material, we must have gone through numerous experiments, and now we have achieved it It's amazing to see the products. It's conceivable that the research and development process is also very magical.
