Chapter 111 Ceramic Armor [Requesting for further reading]
“Old Wang, stop scratching.”
Gu Nan shouted and went out of the house to meet Wang Jinyang.
"Is there anything similar to ceramics in the house you cleaned?"
Wang Jinyang nodded: "Yes."
But he didn't scratch it. The ceramics in the cave were too ugly. He brought them back to the earth and sold them. No one bought them for a dollar each.
Gu Nan was overjoyed, this meant that there definitely was a kaolin mine in this village.
"While there is still time, go to the back to find the location of the kaolin mine."
After that, Gu Nan pulled Wang Jinyang and ran towards the back of the village.
After searching around, Gu Nan finally touched the white and delicate kaolin clay.
"It feels good!"
"Old Wang, dig a bag back quickly."
Hearing this, Lao Wang took out a new bag and started digging.
Soon, Gu Nan and Wang Jinyang each carried a bag of soil and a bag of loot and started running towards Donglin City.
At night, the world is dominated by monsters, and there are endless roars. Even if Gu Nan and Wang Jinyang did not run to the mountains and grass, they still felt that the roars were right next to them.
Although the neighing sounds continued, no monsters below the sixth level came to deliver food to them, and no monsters above the sixth level came to deliver food to them.
Soon, the two of them ran to the gate of Donglin City.
The soldiers guarding the city were stunned when they saw Gu Nan and Wang Jinyang carrying two large bags each.
If they remembered correctly, Gu Nan and Wang Jinyang went out in the afternoon, but came back in the evening carrying two large bags of things! ?
“What are you doing?”
Gu Nan waved his hand and said it was not worth mentioning: "I dug some soil."
"???"
Digged soil?
While everyone was confused, Gu Nan and Lao Wang carried their things into the city.
Wang Jinyang went straight to the logistics office with the scraped things, while Gu Nan returned to his place of residence carrying two large bags of soil.
As soon as he returned to his place of residence, Gu Nan rubbed his hands happily, and at the same time secretly greeted the people in the scientific research department.
I have never seen the kaolin clay in the caves in books, and I have never heard anyone talk about it.
Logically speaking, he has read a lot of cave books, but he has never seen one written like this.
"No wonder the technology in terms of blood and energy has collapsed." Gu Nan couldn't help but complain. Kaolin is a resource that can be used in national defense, including aircraft, armor, armor, etc. its shadow.
He didn't believe that no scientific researcher had discovered such things as cave ceramics after so many years of fighting between humans and caves.
If no one really finds out... then pretend he didn't say anything.
With kaolin, Gu Nan can make ceramic armor, and it is not just ordinary ceramic armor.
Ordinary ceramic armor is characterized by high hardness, but it is easy to break. When broken, it absorbs energy to reduce the damage of bullets to the human body. At the same time, this kind of ceramic armor needs to be restrained, otherwise the durability will decrease quickly after breaking.
But changing the internal structure of the ceramic makes the internal grains of the ceramic smaller and the bonding stronger, and the ceramic will become tougher.
Tough ceramics are also used to make knives, armor, engines, etc. It can be said to be a very important resource.
In addition to ductile ceramics, there is also a piezoelectric ceramic with energy conversion function.
If the two ceramics can be combined, the ceramic nails will be really awesome.
Moreover, the kaolin in the cave contains energy particles. Even if it is very small, it is definitely many times better than the kaolin on the earth. Gu Nan couldn't help but smile as he pictured the appearance of ceramic armor in his mind.
If ceramic armor can be achieved, it will be his most awesome invention so far.
Ceramic armor can block bullets. The power of bullets is at least higher than that of a second-grade warrior.
And the ceramics used in tanks can block missiles.
If the cave kaolin can be used to make tough ceramic and piezoelectric ceramic armor, then it is very possible to block attacks of the sixth and seventh grades.
Just do it, Gu Nan put the kaolin in the dormitory and ran to the logistics office.
When he came to the logistics office, Wang Jinyang had just finished changing things. When he saw Gu Nan coming, Lao Wang smiled happily.
"Gu Nan, we made hundreds of millions on this trip."
We made a lot from the energy stones alone. As for the energy heart, Gu Nan took them all.
Gu Nan stretched out his finger and waved it left and right: "You are short-sighted, we will make a lot of money."
"Oh? Tell me in detail." Lao Zhang puffed his head. With a smile, he also wanted to know how Gu Nan made so much money.
Gu Nan chuckled lightly and did not elaborate, but asked: "Is there a device for smelting ceramics here?"
Lao Zhangtou shook his head: "There is no such thing. If you want to make ceramics, you have to go to the surface."
Gu Nan nodded. It seemed that he needed to get out of the cave.
Unexpectedly, less than a day after going down to the underground cave, he would return to the surface again. It was too fast.
"Old Wang, let's go and carry the soil back to the surface. Anyway, we can go down to the cave at any time."
"Okay." Wang Jinyang guessed that Gu Nan was going to invent ceramics and do this. This kind of invention makes Gu Nan exhausted to death by himself, so he definitely needs his help.
To convert ceramics into tough or piezoelectric ceramics, they must first be fiberized.
Ceramic fiberization usually has two basic guiding ideas: one is to directly use the target ceramic material as the starting raw material, and form it by melting and spinning at high temperature in the glass state, cooling and solidifying, or spinning through the action of spinning aids. Fibers are obtained by sintering at high temperatures.
The second is to use a precursor that contains the target element and can be cracked to obtain the target ceramic (it can be an inorganic precursor or an organic polymer precursor), and the fibers are spun by dry or wet spinning at high temperature and cracked. become.
Gu Nan decided to take the first option, but the second option was a bit difficult.
After carrying the old soil, Gu Nan and Wang Jinyang returned to the surface.
After returning to the surface, Gu Nan called Guo Yan. If Guo Yan was not in Donglin City, he must be at the surface military camp.
“You want equipment to make ceramics?” Guo Yan was puzzled.
"Commander Guo, let me whisper, it's about armor. You will know after I make it."
As soon as he heard that it was about armor, Guo Yan became serious. He immediately sent someone to get the best equipment and materials for Gu Nan.
As soon as the equipment and materials arrived, Gu Nan was shocked.
With such good equipment, has no one thought of trying to get ceramic nails?
However, the high-efficiency application of piezoelectric ceramics and ductile ceramics is only 10 years away.
Gu Nan was not in a hurry, but bought a lot of books on ceramics and wrote down his thoughts in his notebook.
Wang Xueba Jin Yang explained theoretically, while Gu Nan did it by hand.
Ceramic armor definitely cannot just consist of ceramics, Gu Nan added technological fibers and alloy fragments to it.
Ordinary ceramic armor eliminates the energy of external attacks through partial fragmentation. However, after partial fragmentation, as long as the fragmented part is attacked again, the armor will be broken.
So Gu Nan stacked five or six layers of fibers, ceramics, alloy fragments, fibers, ceramics...
Don’t think that ceramics are so thick. The dimensions of ceramics that really should be used for national defense are nanometer-level technology.
Although Gu Nan's current ceramic armor cannot reach the nanometer level, it is still quite thin.
