Another way of thinking 3406
Both graphene and ultra-high molecular weight polyethylene fibers are relatively high-end materials, and they themselves have absolutely no problems.
And there is no conflict between the two in terms of chemical properties or physical properties.
They can be combined!
So the rest is the integration problem?
Is it the way of fusion?
Zhang Guodong quietly opened his eyes, staring at Qin Luo firmly: "Professor Qin, what do you mean, our way of fusion is wrong?"
"Sieve method, eliminate wrong answers, and the remaining answers must be correct."
"Since there is no problem with the material itself, then there is only a problem with the fusion method!"
"Professor Zhang, I have an idea. The hardness of graphene itself is relatively hard. Spraying it on the surface of ultra-high molecular weight polyethylene fibers will more or less affect the flexibility of ultra-high molecular weight polyethylene fibers. You said Could this be the reason for the break?" Qin Luo half-closed his eyes and said with a smile.
Zhang Guodong didn't speak, his mind was spinning rapidly, constantly thinking about Qin Luo's words.
He frowned, and kept gesticulating with his hands in the air, as if he wanted to catch something.
After a while, Zhang Guodong suddenly opened his eyes!
"It's possible!" Zhang Guodong snapped: "The graphene material is sprayed onto the surface of the ultra-high molecular weight polyethylene fiber to form a hard protective film."
"But because the protective film is too thin, the pressure bearing capacity is not strong enough."
"This is most likely the cause of the fracture!"
"Is there any solution?"
"We can spray the coating thicker to strengthen the pressure-bearing capacity of this protective film!" Zhang Guodong said.
Qin Luo: "!@#￥%..."
For some reason, he felt that Zhang Guodong was wrong.
Qin Luo had an illusion in his heart that this thing might not be a problem with the protective film!
"Professor Zhang, have you forgotten why we chose to use ultra-high molecular weight polyethylene fiber material as the main material of the parachute?" Qin Luo asked.
"Because the ultra-high molecular weight polyethylene fiber is relatively soft, this..." Zhang Guodong wanted to say something at first, but as he spoke, his voice became weaker and weaker.
In the end, there was no sound at all.
He realized it was wrong!
The reason why they chose ultra-high molecular weight polyethylene fiber as the main material is because of its softness.
And if the graphene coating is thickened, this property will be completely changed!
If it is equipped on the space shuttle, once the parachute cannot be opened during the landing process, the consequences will be disastrous.
The plane crashed and the people died!The loss is immeasurable!
At this moment, Zhang Guodong's face turned pale, and he was wrong again.
"Professor Qin, I, I'm sorry..." Looking at Qin Luo, Zhang Guodong really wanted to say something, but he couldn't say anything in the middle of the sentence.
In the end, all the words were reduced to three words: I'm sorry.
sorry?
At this moment, Qin Luo smiled.
Did Zhang Guodong do something wrong?
not at all.
It was just a failure of an experiment, so there was no need to say sorry!
"Professor Zhang, you are serious. You have not been sorry to anyone. Now it is just an experiment failure, which caused neither casualties nor losses."
"Why do you say sorry?"
"I……"
Qin Luo waved his hand, interrupted Zhang Guodong's words, and said, "Professor Zhang, I have an idea. We can mix graphene powder into the production process of ultra-high molecular weight polyethylene fibers. What do you think?"
