(Revised)
"Hello, my name is Cao Yuan, nice to meet you all."
Not long after Zhou Ji finished the call, a thin young man with glasses who seemed to have a sunny personality came to the activity room of the Xinghai research team.
"Hello."
"Welcome, welcome."
Xia Xu and others came out to greet them.
Since Cao Yuan was able to come, it meant that he had already agreed to join or had some intention to join their research group. Soon everyone warmly invited him to take a seat, intending to strike while the iron was hot and continue the discussion.
As Tang Youxin, Song Yu, Luo Lin and the others were pure information majors and couldn't help much at the moment, so they simply served tea and water and bought some fruits and snacks for everyone.
As for Xia Xu and his friends, in order to avoid interrupting their train of thought, they continued brainstorming after they became a little familiar with each other.
Of course, before this, Xia Xu also took a look at Cao Yuan's attributes, and the results also made him eyes light up.
Name: Cao Yuan
Life Level: 1
Fate potential: Physicist (4 stars)
Talent potential: Physics (4 stars); Materials Science (3 stars)
Special: None
Obsession: None
Favorability: 67
Four stars for physics.
This is a very broad talent.
Although it may not be as good as Victor's hanging wall, it is not easy to find a five-star level, especially a five-star physics level, which may not appear even after thousands of years.
With the addition of a four-star physicist like Cao Yuan, their Xinghai research team will definitely be more powerful in everything they do.
Especially in the design of passive exoskeletons, Cao Yuan, a physicist who also majored in materials science and is familiar with graphene, may be more useful than Zhou Ji and Walker.
"There is no problem in using graphene to make protective clothing, but I don't think it is necessary to give up the buffer layer. Instead, the structure of the entire passive exoskeleton can be improved on this..."
Amid the heated discussions among the crowd, Cao Yuan also felt a sense of mutual admiration and soon became part of the discussion. After listening to everyone's ideas, he came up with a new suggestion, or good news.
"Recently, Professor Gao from Zhejiang University has made a breakthrough in graphene research. They have produced a graphene sponge, which can also be called a carbon sponge..."
Cao Yuan is indeed a professional in graphene research, and he immediately revealed a shocking piece of information that has not yet been revealed.
Zhejiang University has now developed a graphene sponge, and although it is called a sponge, it is actually an aerogel.
Aerogel is mostly air, so light that it is almost negligible. It is also the lightest known solid in the world, with a density lower than that of air.
But this graphene sponge is more than just light.
Graphene sponge has super elasticity and can recover to its original shape after being compressed by 80%.
And the more it is compressed, the higher its density, just like a sponge becomes hard when squeezed. The stronger the impact, the higher the strength and hardness of the graphene sponge will become, eventually reaching a level close to that of a graphene sheet.
Therefore, its ability to resist compression and impact is extremely exaggerated, and it can withstand an impact force of more than 14,500 pounds per square inch.
This means that only a thin layer is needed, and by mixing materials such as carbon nanotubes as a skeleton, a bulletproof vest that is extremely light and thin and can easily defend against large-caliber armor-piercing bullets can be obtained.
No, it shouldn't just be called a bulletproof vest.
Because it can defend against both blunt and sharp weapons, and with a layer of graphene surface, it becomes a super protective clothing with countless performance advantages such as heat dissipation, sweat absorption, breathability, and sound absorption.
"With the graphene surface layer and this graphene carbon sponge, we only need to implant a certain amount of carbon nanotubes as a skeleton. I think we no longer need to design any additional passive exoskeleton..."
After hearing the news from Cao Yuan, Zhou Ji and Walker's eyes lit up and they became completely excited.
Is this graphene sponge only used for bulletproofing and reducing impact force
In their opinion, this is a bit too much of a waste of resources.
Sponge, as the name suggests, is a sparse and porous structure that absorbs impact and is compressed, and then rebounds after the impact is buffered.
Graphene sponge is the best among them, and it can return to its original shape even if it is compressed by 80%.
An object can absorb impact force, compress itself and then rebound. To put it simply, this is called a spring. To put it more advanced, this is some kind of energy storage structure.
Mechanical energy, like other energies such as thermal energy and electrical energy, can be stored and converted as long as there is a suitable method. For example, a clockwork watch stores the mechanical energy of twisting the spring and then releases it slowly.
To exaggerate a little more, by using any mechanical energy, including human power, to transport large amounts of stones to high places, these stones essentially serve as "batteries" for storing mechanical energy.
When needed, the mechanical energy can be utilized by throwing stones down to drive ropes, pulleys, etc., and then converted into electrical energy by using a rotary generator.
With a ready-made "spring" like graphene sponge, they no longer need to consider things like energy storage and conversion of mechanical energy. They only need to arrange it reasonably to make it a ready-made energy storage component.
Just like muscles contracting to store energy, storing up one's own strength and then releasing it naturally has the effect of increasing limb strength.
Through structural design, they may also be able to improve the conversion and transmission of mechanical energy.
Just like many martial arts and fighting skills say that power comes from the waist and the legs, they are truly able to transmit and concentrate the power of the legs, waist and abdomen to one point, thereby forming super explosive power.
And the stronger the impact on the graphene sponge, the harder it becomes.
If the design is reasonable and a layer of 'skeleton' is woven using graphene sponge, then the last link of the exoskeleton armor will be perfectly solved.
Under normal circumstances, this layer of skeleton is as soft as a sponge and will not affect movement at all. However, as long as it is subjected to gravity and impact, it will harden and form a real skeleton, playing the role of dispersing weight and impact like a spine.
To give a more vivid example, if a huge heavy object falls down, you will be knocked down if you reach out to lift it.
But if the arms, legs, and spine had a layer of skeleton that hardened quickly, the arms and spine would not bend due to the weight, and the impact force and gravity would be dispersed and eventually transmitted all the way to the ground.
In this way, not only the defensive capability is enhanced, but also the most core function of the passive exoskeleton, such as load-bearing capacity, is solved.
Bulletproof, puncture-proof, impact-resistant, enhancing limb strength and load-bearing capacity, more efficient transmission and utilization of physical energy to reduce loss, isn’t this the ultimate pursuit of passive exoskeletons
The most outrageous thing is that it can be as light as a piece of clothing and does not require any additional mechanical structure or accessories.
It can be said that if it is really manufactured in this way, it will be the most perfect passive exoskeleton armor, which is far more practical than the powered exoskeleton that can be made at this stage.
