This is how black technology should be used

Chapter 97 Graphene Protective Armor

In fact, the engineers and experts who came to the [-] Institute have all heard of Li Future's name.

After all, the Science and Technology Alliance has been established for several months. On the day of its establishment, the superiors even specifically mentioned "Li Future Studio", and the studio representative Li Future met all the big guys present at the time.

After all, he is too special, everyone in the audience is over 40 years old, and he is a pink and tender college student in his 20s.

And being able to have a meeting with them is obviously not the usual pink.

It's just that some time ago, the Science and Technology Alliance has been coordinating resources within the Science and Technology Alliance. During this period, various science and technology projects did not grow much, so not many people contacted Lifuture Studio through the Practical Technology Group.

Of course, this is what coordination of resources is for.

After the resource coordination and overall planning is completed, there are some technical foundations provided by Li Future Studio, and various scientific and technological projects have developed rapidly.

This time, the [-] Institute is also here because of the original video. It shoulders the task of providing the army with advanced individual powered exoskeleton systems, and is very concerned about the information in this regard.

When the video came over, the top leader discovered that there was someone in it who happened to be Li Weiwei, whom he had met at the founding meeting of the Technology Alliance. After thinking about his relationship with Li Weiwei Studio, especially the studio's technological strength, he Contacted him.

Once you get in touch, you know you've found the right person.

After getting the technology, Li Future participated in several confidential video conferences, so more people in the exoskeleton technology team knew about Li Future.

Originally, Li Weilai was criticized by some experts and engineers because of his age, but after several meetings, they also agreed with Li Weilai.

Without him, it is a technical bullpup!
Not only is the technology of Li Future Studio excellent, but Li Future himself has a very solid grasp of technology.

It's just that they couldn't have imagined that the technology of Li Future Studio would be so awesome!
"Graphene batteries are really powerful. We even made a very small graphene battery before. Its energy density is amazing, and it is very safe. There is no risk of fire and explosion. It is light in weight. It is good everywhere, but it is too large. Expensive!"

Hearing someone say this, Li Weiwei was taken aback for a moment: "You really have made graphene batteries, can you let me see?"

"of course."

The two sides exchanged "hostages". Li Future showed them the general data about graphene batteries and mass-produced graphene he mentioned, while they showed Li Future the actual graphene batteries and test data they had made before.

After Li Weiwei got the battery, he found that it was similar to a No. 7 battery. He weighed it with his hands and found that the weight was about the same, about 10 grams.

He also looked at the actual data and found that the battery used a total of 9 grams of graphene.

The price of real graphene is more than a thousand yuan per gram, so the cost of these 9 grams of graphene is tens of thousands. Adding their technology, their labor, etc., this battery will cost at least tens of thousands.

However, its performance is really good. According to their measured data, its performance is 2.5 times that of the main lithium batteries on the market.

It may not be clear to say so, let's take electric vehicles as an example.

At present, most of the electric vehicles on the market can run 300-500 kilometers on a single charge, and some claim to be able to run further, but those are very few, and it is not sure whether they can run as far.

Take the median value of 400 kilometers as an example, its 2.5 times means that it can run 1000 kilometers on a single charge!

If you can run this kind of kilometers on a single charge, then the market share of pure electric vehicles will not only be 10%.

But there is no way, the current lithium battery is not very powerful, and it is in an embarrassing energy range.

But graphene is also "not powerful", or the price is too powerful!

A small No. 7 graphene battery costs tens of thousands of yuan, while a No. 7 energy-concentrating ring dry battery is only a few yuan, and a No. 7 lithium battery is only a few dozen yuan.

If graphene is used as a car battery, it must use hundreds of kilograms.

Then the cost of graphene alone has to be... Forget it, with this money, it is better to buy a J-20 fighter jet.

Of course, this is in the past. When the bigwigs in the meeting room read the information provided by Li Future, they will say: "Wait a minute, we can't just let it go, it's done, it's all done!"

Without him, the technology mentioned by Li Future is so amazing!
"This mass production technology is too strong!"

"Unbelievable! Incredible!"

"So you don't have to worry about graphene in the future, just use it casually?"

"Well, it's not for casual use. It's still more expensive than lithium batteries, but the effect is damn good!"

"The graphene battery technology of Lifuture Studio is also very high. Our energy density is only 2.5 times that of lithium batteries, but theirs can already reach 5 times that of lithium batteries!"

"Yeah, it doesn't matter if it is a little expensive to reach this level, it can already be commercialized on a large scale."

"In fact, it is not expensive when converted in equal proportions. Fortunately, major domestic battery manufacturers have joined the technology alliance. After resource coordination, other companies can also use the technology. Otherwise, the release of this technology... will definitely be a major earthquake in the field of energy storage."

"Anyway, foreign battery technology companies are about to run out. If this technology is operated by the higher authorities, it can basically be used as a strategic weapon."

"The matter of international strategy has little to do with us, but if graphene can really be mass-produced and the price is not too outrageous, then our powered exoskeleton design will have to be changed."

"How to change it? Isn't it enough to just change the battery?"

"Protection, the protection performance of graphene armor is so good that it explodes, and the weight is still very light! If it is made into armor and installed on the exoskeleton, what do you think will happen?"

"Hiss, how did I forget this..."

A few years ago, the Southern Highest University of the Freedom Federation conducted a microscopic ballistic test, shooting a tiny silicon particle at a single-layer graphene at a speed of 2000mph, and found that this honeycomb-shaped material can effectively disperse kinetic energy. 10 times stronger than steel!
In this experiment, the initial velocity of the silicon particles reached the level of a rifle. The test proved that graphene has a very strong bulletproof ability if applied at the macro level.

Electron microscopy showed that the graphene absorbed the energy of the impact, deformed itself into a conical shape, and diffused outward in multiple directions, fragmenting within a certain radius.

The researchers say this fragmentation process is the weakness of single-layer graphene, but even so it is 2 times stronger than Kevlar and 10 times stronger than steel!
Of course, this experiment did not get the theoretical value of "graphene is 200 times stronger than steel".

There is a reason for this though, as they were unable to use conventional methods such as barrels or gunpowder on a test of this scale.

After all, their "target" is single-layer graphene, which is only a little bit. If they really make a conventional rifle target, their funds will not be enough.

Although the entire process of the experiment requires an electron microscope to observe, it already exists in the electron microscope laboratory, so they don't need to spend money to buy it again.

So they used a laser to accelerate micron-sized silica spheres on a graphene target, and then the bullet was propelled into the graphene sheet at speeds of up to 2000mph via gases created by laser pulses that rapidly vaporized the gold film.

The researchers then calculated the difference in energy of the bullet before and after impact to determine how much energy was absorbed.

Later, researchers at the Free Federation Gotham City University created a new material, which is composed of two graphene sheets on a silicon carbide substrate.

Why use two slices?
This thing is also amazing. The research team said that when two sheets of graphene are aligned and stacked together, this material has a wonderful characteristic-hardening effect!
Under normal conditions, the material is as light and flexible as aluminum foil, but once subjected to sudden mechanical pressure, it will suddenly "harden" and become harder than diamonds!
Everyone knows that the Mohs hardness of diamond is 10, which is basically the hardest thing in the world, and this new material is harder than diamond when it is subjected to mechanical pressure.

Similar experiments have actually been done in some laboratories of Fanxing, but due to insufficient funds, all experiments are carried out on the "micro level", and no larger-scale experiments have been done.

The graphene battery experiment of their individual power exoskeleton team is somewhat "macro level". At least 9 grams of graphene rubbed out a No. 7 battery.

Of course, since their experiment was not complicated, the money they spent was not too much, only tens of thousands of dollars.

According to their understanding, with the same military background, another group that needs to study graphene applications will spend more money.

It's the same as the graphene armor they thought, the project team is also researching graphene armor, but the module is bigger and used in more places, and it is used on helicopters.

Research in that project has been going on for more than a decade, and the main problem was to develop a cheap and reliable fabrication process for ultrathin graphene sheets.

According to the product public information released by relevant institutes, the density of the bulletproof armor plate prepared by it is lower than 2.8 grams per cubic centimeter, which is only 30% of the density of bulletproof steel plate and 56% of that of bulletproof titanium alloy plate.

Compared with aviation aluminum alloy, it only increases by 3%.

After many actual target shooting tests, its bulletproof effect and ability to resist multiple strikes are significantly better than bulletproof titanium alloy plates of the same thickness.

It can effectively resist 100mm tungsten alloy armor-piercing projectiles with a muzzle velocity of 900m/s at a distance of 12m!

Tungsten alloy armor-piercing projectiles are the way Fanxing handles tungsten.

Well, one of a kind.

Powerful.

Of course, this material can block 12mm tungsten alloy armor-piercing bullets, because the graphene content of this material is about 1%, and the rest are cheap aluminum alloy and silicon carbide materials.

Cough cough, there is no way, graphene is too expensive.

To develop a cheap and reliable graphene application technology requires a lot of upstream and downstream resources. At present, only military research institutions are doing it. After all, many technologies were initially used for military purposes.

But now, there is no need to integrate upstream and downstream technologies across the country. Li Future directly brings cheap and reliable graphene technology.

Although this is not a cheap and reliable graphene application technology, graphene is "used casually". Doesn't this mean that there is no limit to future experiments?
Experiments are done casually, graphene tubes are enough, and application technologies will definitely spring up like mushrooms after rain!

Just like the graphene content studied by another group is only 1%, and the rest of the armor made of aluminum alloy and silicon carbide can block 12mm tungsten alloy armor-piercing bullets, so how about increasing the graphene content to... 2%?
Or even 5%, 10%?
Ahem, 100% graphene is still too expensive. It’s okay to make a small battery, but it’s still reluctant to make a large piece of armor.

Moreover, the 100% graphene protection effect is not necessarily the best. After the mass-produced graphene comes out, do experiments slowly, and you will definitely be able to find a ratio that is suitable (pian) suitable (yi) and easy to use.

For the powered exoskeleton team, with the lead of the armor part, other parts have also been enlightened.

"Since the strength of graphene is so good, we can also use it to make basic bones, which is light and strong, how wonderful!"

"Yes, I agree with this modification!"

"Heat dissipation, and the heat dissipation module!"

"Yes, graphene has very good thermal conductivity!"

"Indeed, I remember that pure, defect-free single-layer graphene has a thermal conductivity of up to 5300W/mK, the highest thermal conductivity of any carbon material so far, higher than the 3500W/mK of single-walled carbon nanotubes and multi-walled carbon nanotubes 3000W/mK. Even when it is used as a carrier, the thermal conductivity can reach 600W/mK!"

"There is also a detection module. Graphene can be made into a chemical sensor. This process is mainly completed through the surface adsorption properties of graphene. According to the research of some scholars, the sensitivity of graphene chemical detectors can be compared with the limit of single-molecule detection." Compare."

"Yes, graphene's unique two-dimensional structure makes it very sensitive to the surrounding environment!"

"In this case, it can still..."

Everyone, you said one by one, and the train of thought quickly opened up, and even took off directly!
Finally, I summed up my opinions, good guy, this is not an exoskeleton for individual soldiers, this frankly adds an arc reactor to make the Iron Man armor!
"Okay, okay, our current task is not to build Iron Man, but a simple general-purpose individual exoskeleton. We can write down these goals first, and then continue to study after completing the primary task."

"Don't think about the all-graphene exoskeleton. Although it is indeed cheap according to Comrade Li Future's information, the all-graphene exoskeleton is still too expensive, so the main material of the exoskeleton remains unchanged."

"Currently the most reasonable projects are graphene batteries and composite graphene material armor, making breakthroughs in the first place."

“As for the models, we need military and police types. The military type is also divided into several types such as simple, heavy, and assault. The police type is also divided into police types, such as public security, firefighting, special, forest, etc. "

Speaking of the powered exoskeleton used by the police, Li Future suddenly thought of some "fancy" operations, so he said, "I have some ideas..."

When they heard that Li Weiwei had new ideas, everyone present was very interested. At first, they looked calm and looked like they were listening carefully, but after a while, they were frightened by Li Weiwei's imagination.

Director Liu even shook his head again and again: "No, no, how can this work?"

　Thank you Yehuxu for your reward~~
