The spring cold is approaching, and a sudden late spring cold makes everyone put on the cotton-padded jackets they just took off again.
These days, down jackets are not as popular as they were later, and the main clothing for most people to keep out the cold is still heavy, thick cotton-padded jackets.
Qian Siming wrapped some of his dark green military coat tightly around his body and breathed into his palms to warm them.
"Why don't you come, Lao Su!"
I have been waiting for him at the bus stop for almost twenty minutes! Qian Siming thought in his heart.
"Old money!"
"here!"
Su Che poked his head out from a black Santana and called Qian Siming, standing in the cold wind.
"boom!"
Qian Siming closed the car door forcefully and asked in confusion:
"Lao Su, where are you taking me? And where did your car come from?"
Su Che, who was sitting in the driver's seat, smiled and said:
"This car was borrowed from the school. We are on a business trip today!"
When Su Che said this, Qian Siming became more curious, but he did not continue to ask, but waited for Su Che to give an explanation.
As Su Che drove the car, he looked at Qian Siming sitting behind him through the rearview mirror.
When he found that the other party did not continue to ask questions, he felt that he was bored, so he stopped hanging on to the other party and said:
"Go to the Aerospace Research Institute in the north. I heard that they have developed a new material."
Qian Siming became even more confused after hearing this. The Rocket Research Institute is not ranked high in the domestic materials industry. What is so good about the new materials they have produced?
"What amazing new material they have come up with is worthy of your fanfare."
Qian Siming asked with some confusion after touching the leather seats of Santana 2000.
It's not easy to borrow a school car. If Su Che didn't attach great importance to this visit, it would be impossible for Su Che to borrow this car.
"They have prepared a new carbon-based composite material, which is said to have excellent performance at high temperatures."
Su Che turned a corner and then spoke.
"How good can the performance be? At most, it can perform well at 1,200 degrees."
Qian Siming was a little disdainful. He knew very well how much materials the Aerospace Research Institute had.
When Su Che heard the unruly Qian Siming's contempt for the Aerospace Research Institute, he couldn't help but say:
"I'll scare you to death if I tell you! Their material performance is more than twice that of Yingjiang!"
"And it's the latest data from Taikajia Mingsuni's laboratory. The data from the Rocket Research Institute is twice as high as theirs!"
"This is impossible!" Qian Siming couldn't help but retort immediately.
"If you say that they have reached the domestic advanced level, it is more credible than this! Old Su, don't joke about these things!"
Su Che did not argue too much with Qian Siming because he understood that there was no point in arguing about it now.
As long as he sees the actual objects produced by the Aerospace Research Institute, Qian Siming will be honest.
Santana ran all the way and soon arrived at Qingjiang District, where the Rocket Research Institute is located. The area around the Rocket Research Institute is currently undeveloped.
Most of the area is still farmland, and of course these farmlands will gradually disappear during the urbanization process in the following decades.
Su Che parked his car on the side of the road outside the institute. This car belonged to the Aerospace University. According to the confidentiality guidelines of the Rocket Institute, it would be more troublesome to drive in.
He took Qian Siming to the gate of the institute.
After handing the letter of introduction to his unit to the security personnel at the door, Cheng Wu, with an expressionless expression, looked at the letter of the Aerospace University and the steel seal above that could not be forged, before letting them enter the institute.
Su Che walked over according to the location of the Rocket Research Institute's dean's office in his memory.
Walking to the door of the office and looking through the office window, there was no figure of Zhang Xingyang in the office.
"Professor Su, Professor Qian? What are you doing here?"
Holding a thick stack of drawings, Geng Bo pushed up his glasses and asked with some confusion.
Su Che turned around and saw that the visitor was Geng Bo, and said a little happily:
"It's Geng Bo!"
"Let's come find Zhang Xingyang. Do you know where he is? He doesn't seem to be in the office?"
Geng Bo looked inside the office through the bluish glass, and sure enough, Zhang Xingyang was not there.
"Xingyang, if he is not in the office, he is probably in the materials laboratory."
"If you are not in a hurry, I will take you there when I go to the drawing room to deliver the drawings."
Qian Siming nodded, indicating that he was not in a hurry, and said:
"We are not in a hurry. You can go and deliver the things first. We will wait for you here."
Geng Bo nodded and did not continue to say anything, but quickly walked to the drawing room on the second floor.
Su Che and Qian Siming watched him leave. Qian Siming turned to look at Su Che and asked:
"Lao Su, what are the details of their materials? Do you understand them?"
Su Che no longer concealed anything at this time and said straight to the point:
"I also know about this material from my daughter Xiaoxiao, who is now interning in the materials laboratory of the research institute. According to her, this material is a carbon-carbon composite material. Its high-temperature performance reaches its maximum at 3200 degrees, and its strength It can reach 412MPa!”
Qian Siming interrupted Su Che without waiting for him to continue, narrowed his eyes and said:
"Are you telling me a science fiction story here? If they made a material with such strength, I would eat the material on the spot!"
"Lao Su, don't be deceived by your daughter!"
Su Che smiled and was not annoyed by Qian Siming's words. Anyone familiar with Qian Siming knew that this guy liked to bet with others, but he never seemed to win a bet.
"Old Qian, I won't bet with you anymore, I'm afraid you can't afford to lose!"
When it came to betting, Qian Siming immediately became interested and said with confidence:
"I won't lose this time! I'll put my words here. If they really make it, I'll eat it on the spot!"
Geng Bo just came back from delivering the drawings at this time. When he heard that Qian Siming was betting with others again, he suddenly became interested:
"Professor Qian, count me in, I bet you lose!"
Qian Siming was naturally open to anyone who came, and he was even more excited when someone was willing to play with him.
"good!"
When Geng Bo heard that Qian Siming agreed to the bet, he looked at each other and laughed with Su Che.
Several people went directly to the materials laboratory without wasting too much time.
Just after entering the materials laboratory, Zhang Xingyang was fishing out a stack of carbon fiber cloth that exuded a faint blue light from a pool of liquid in the hot furnace.
The few people who came in after pushing open the door were all attracted to the material as soon as they saw it.
"Is this the lining to be used in the combustion chamber?" Geng Bo asked first.
Zhang Xingyang, who was still carefully shaking off the liquid on the material, looked up at the people standing around him and said casually.
"This is to be used on the nozzle. The combustion chamber lining material has not yet been developed, and we do not have the preparation conditions in the research institute."
Qian Siming carefully looked at the pool of liquid he had just soaked and asked:
"Is this a silicone-based antioxidant coating solution?"
Only then did Zhang Xingyang turn away from the materials in his hand and took a closer look at the person standing in front of him.
Unexpectedly, there are people who know a little bit, Zhang Xingyang thought in his heart, and said:
"That's right, but there is also a trace amount of nano-metal nickel in it, as well as other things."
After Zhang Xingyang's hard work all night, the coating of carbon-carbon composite material was finally completed. Only then was the preparation process completed.
"This means that the preparation is completed, and the next step is to conduct performance testing."
Zhang Xingyang looked at everyone who was looking at him expectantly and said a little speechlessly.
"Can you let me come?" Qian Siming looked at Zhang Xingyang's young face and asked seriously.
Someone wanted to help him, but it was too late for Zhang Xingyang to be happy. He was almost exhausted after working all night.
Moreover, as a professor of materials science, Qian Siming had no problem at all doing some material performance testing.
Zhang Xingyang slumped in his chair and looked at the three people busy in front of the thermal/mechanical high-temperature tester that day.
Enjoying his rare rest time, Zhang Xingyang was about to fall asleep.
An exclamation suddenly sounded, interrupting Zhang Xingyang's chance to enjoy his beauty.
"This is impossible!"
"How can this be!"
Zhang Xingyang rubbed his face and managed to cheer himself up a little.
He walked to the tester and looked at the experiment record sheet in Qian Siming's hand.
3200 degrees, 537MPa; 3600 degrees, 541MPa; 4000 degrees, 531MPa.
Compared with the previous semi-finished product, it is a complete product that has been graphitized and coated on the surface.
Not only the high temperature resistance has been improved to a higher level, but the strength performance has also been enhanced by about 20%.
"It's not much different from what I predicted. There may be some issues with the purity. What a pity!"
Zhang Xingyang sighed and said a little helplessly.
The purity of materials in this era is a difficulty that Zhang Xingyang cannot avoid. Unless he improves the production of raw materials himself, this is already the limit.
Faced with Zhang Xingyang's Versailles remarks, Qian Siming was instantly annoyed:
“Do you know what this data means!!”
However, the next second, Qian Siming remembered that the Versailles man in front of him was the person who made this material.
"Of course I know what it means. This means that our engine tail nozzle can withstand the impact of greater intensity and higher temperature, which can greatly increase the thrust of the engine."
Seeing the sleepy and yawning young man in front of him, Qian Siming suddenly felt that he seemed to have witnessed the rise of a genius.
This young man, who has not yet reached his thirties, is like a rising star that is about to light up the dim sky of the material world of Dragon Kingdom.
