Do I have any questions? Guo Tailai was confused. When did he say he wanted to ask materials experts for advice?

"Kevra Materials." Looking at Guo Tailai's puzzled expression, Zhao Xiangbei knew that this guy must have left the words behind him and hurriedly reminded him.

Oh!" Guo Tailai said oh, then he was still full of doubts. Did he say he wanted to find a material expert?

I asked you if you could optimize the bulletproof vest, you said it was difficult." Zhao Xiangbei recalled Guo Tailai, who knew that Guo Tailai must remember that this guy's memory was definitely at the abnormal level.

"That's what I said!" Guo Tailai nodded while kneading the dough: "I also said that I'm not a material expert. But I didn't say that I could optimize the body armor, right?"

"You said it was difficult." Zhao Xiangbei laughed: "I didn't say I couldn't do it."

Guo Tailai is about to collapse. What is the reason? It's too illogical, right?

Teacher Shi next to him looked at the two of them with a smile, but most of the time he still stared at Guo Tailai, as if he was very curious about him.

"Have you solved the quality control problem of your production?" Guo Tailai ignored the presence of Teacher Shi next to him and asked directly at Zhao Xiangbei.

"Thanks to the suggestion you made last time." Zhao Xiangbei was amused when he said this: "We went to the watch factory to find three masters, and the assembly accuracy has indeed improved. The factory has only produced large ones before, but has never made such small ones, and has no experience. He is still a master in the watch factory."

What about the group’s problem? Is it solved?" Guo Tailai asked again. Zhao Xiangbei seemed to answer Guo Tailai’s question just now, but if he didn’t know what was produced, Teacher Shi would definitely not understand a word.

"It's almost done. All those who should retire have completed the procedures, and those who should change their jobs have also completed the transfer. The rest is to make the run-in and smooth." Zhao Xiangbei has been busy these days, but he is also very happy."

That, Uncle Zhao and Kevlar's bulletproof vest, for the time being, can only look forward to improving the material attributes and enhancing the protection power." Guo Tailai did not continue this topic, but returned to the bulletproof vest: "At most, add some bulletproof boards with metal or ceramics, and add some bulletproof ability. Teacher Shi is an expert, and should understand."

"Indeed," Teacher Shi said in a timely manner: "At present, the bulletproof vests of various countries are basically the same idea. Of course, the differences in Kevlar materials in various countries have also led to different bulletproof effects. As for bulletproof boards, it also depends on the breakthroughs in materials between countries."

Kevlar's bulletproof vest is made of aramid organic fiber materials and was first developed by DuPont, the United States. This macromolecular organic fiber material is only a major category, but not a fixed one. It may belong to this category by various countries, but polymer molecules are definitely slightly different, which also leads to different bulletproof effects.

The application range of materials is very wide, military, and common for civil use. For example, Guo Tailai used it to make shoe puncture-proof pads. In the 1980s, when China imported DuPont products, the US government did not allow DuPont to export Kevlar brand products to China. Later, it was only after domestic research began to be conducted. "

If you want to have a high bulletproof level, you can only thicken and increase it." Zhao Xiangbei also did his homework: "The domestic troops have not been distributed in large quantities, but a small number of special forces can be used to improve their protection capabilities in some battles."

Guo Tailai understood, this was talking about Zhao Yanyan's side. It might have been distributed, but it may not be the best. So when he heard that Guo Tai said it was difficult, he pestered him and came to him to ask Guo Tailai to find a solution.

Guo Tailai was still happy to do it. But Guo Tailai was not sure. After all, the breakthrough in materials science cannot be solved by patting his head. It is hard to say how long it will take. However, after looking at Teacher Shi next to him, Guo Tailai suddenly had an idea in his mind.

Is there any problem with the domestic bulletproof vests now?" Guo Tailai asked naturally, while preparing chopping board rolling pins and other things. At the same time, he took out the corn starch and sprinkled it on the panel to prepare rolling noodles.

"A common issue." Zhao Xiangbei replied: "The bulletproof board is heavy, and the effect of not inserting the bulletproof board is not enough to prevent rifle bullets. It is not very comfortable to wear, and some angles are not fully protected."

"Mix this one portion of water and three portions of starch." Guo Tailai took a basin the size of a head and handed it to Zhao Xiangbei, asking him to go and talk: "Whike it evenly, the better the mixing."

"Tradition?" Zhao Xiangbei looked at the starch and asked, but did as Guo Tai said without waiting for Guo Tai to answer.

The teacher looked at Guo Tailai's skillful rolling noodles and kept smiling on his face.

Have Teacher Shi ever thought about changing his ideas?" Guo Tailai asked Teacher Shi: "For example, change to a material that can make people feel more comfortable to wear to make bulletproof vests?"

Just like you said, it's hard!" Teacher Shi shook his head and smiled bitterly: "I'm afraid everyone in the world is thinking this way, but if you want to have a good protective effect, you must have excellent mechanical and thermal properties, chemical properties, and resistance to acid, alkali and organic solvent erosion. This will inevitably lead to the material not being as soft as clothes, and it will definitely not be comfortable to wear. At present, it can only be called a bulletproof vest, but it cannot be considered a complete bulletproof vest." "

The first priority is to be able to save your life, and comfort can only be at the back." Zhao Xiangbei stirred the batter with chopsticks and walked over to interrupt.

"If the materials are suitable, they are lighter and thinner, and can also wrap around a larger body. This is the best, right?" Guo Tailai asked.

"Of course!" Zhao Xiangbei replied naturally for the obvious reason."

Then look for this kind of material!" Guo Tailai said with a smile: "Find the kind of material that is usually soft and comfortable, which becomes hard immediately when attacked by bullets or bayonets!"

It's not easy!" Teacher Shi smiled without saying a word, and Zhao Xiangbei criticized Guo Tailai directly: "You seem to really not know the hard work of material research. Is this new material so easy to find? Do you know how many people have to work hard in it, and you still have to have good luck. Do you think something like an iron meteorite can come out casually?"

Of course, Guo Tailai knew the complexity of materials and the hardships, but isn’t it for his girlfriend?

"Is this kind of material difficult to find?" Guo Tailai looked unbelieving and said, "Even if it is difficult to find specific ones, this big type is easy to find, right?"

Please find one for me!" Zhao Xiangbei was extremely despised by Guo Tailai's arrogant behavior, and felt that it was definitely a mistake to bring Teacher Shi over today.

"Here!" Guo Tailai snatched the corn starch paste that Zhao Xiangbei had mixed very well. He reached in and plucked it. A piece of cracks like tofu was grabbed, spread out his hands and immediately flowed away from the cracks in his fingers. Guo Tailai easily inserted one finger into the liquid paste: "This is very soft, right?"

Soft." Zhao Xiangbei nodded and said, "Your height is a little thick."

Guo Tailai ignored him, pulled out his hand and clenched it into a fist, and punched it. Bang, the liquid seemed to suddenly become extremely hard, and bounced Guo Tailai's fist back."

Is this hard?" Guo Tailai raised his head and looked at Zhao Xiangbei and asked.

What greeted Guo Tailai's eyes were two surprised faces, Zhao Xiangbei and Teacher Shi.js3v3
