Before returning to the college entrance examination, I became popular in the science circle

Chapter 257
"Give...drawing force!" Wu Tong reported a strength parameter again, in order to achieve the degree of orientation she wanted.

With Wu Tong as the absolute core, teamwork, and many runs-in, several core experimenters on the operating table have been able to cooperate with Wu Tong like an arm and a finger, strictly following Wu Tong's requirements, or under Wu Tong's instructions. Under the operating settings, the experiment continues step by step.

The anode electrode is oxidized and pulsed electricity treats the surface to form a better contact surface.

While gradually increasing the temperature to 50℃, the carbon wire is washed with water by dipping method to prepare for sizing, and then further sizing is performed to form a protective film on the surface of the carbon wire.

Carbon filament is a brittle material. Sizing changes the surface properties of carbon filament, increases the wear resistance of carbon filament, makes the carbon filament better bundled and enhances stability, which is also the key point to achieve the super performance of carbon fiber.

The sizing agent will be used by Tao Ran and Ruan Chengxu. While waiting for the pre-oxidation and carbonization process, under Wu Tong's instructions, the required strong oxygen resin was synthesized.

Wu Tong further confirmed that the test data matched the strengthening material she had deduced.

The progress so far is going smoothly, and the atmosphere in the laboratory is rigorous and accompanied by the pleasure of advancing bravely.

The prepreg process begins.Cheng Huanan watched the operation, followed up and assisted, and grasped the accuracy of the prepreg.The preparation of carbon fiber prepreg is one of the key steps in making carbon fiber products, which affects the performance and quality of the products.

The amount of prepreg and the degree of infiltration need to be carefully controlled. At this point in the experiment, more than 70.00% has been achieved, and nothing can be ignored.

“Keep storage cold!”

···········
Pre-oxidation treatment, high and low temperature carbonization take turns, various chemical reactions are intertwined, making people almost dizzy...

Finally, after some rewinding and unwinding, they got a 48K large wire harness carbon fiber material.

Holding it in hand, the extremely light and thin feel and weight made several experimenters stare intently at the material they prepared under the leadership of Mr. Wu.

Although they haven't used the testing equipment yet, whatever they do, they all have a background in materials for a long time. From the initial learning to now, it takes at least ten years.Whether the material is good or not depends on visual inspection.

"Mr. Wu, have we succeeded?" They successfully developed it. Tao Ran's voice was trembling, and he took a step back before speaking.Even though he knew that the strength of this thing might be enough for everyone present to stretch it at the same time, it might not be able to tear it apart, but the caution in the face of this new material made him involuntarily make a move.

"The preparation is successful. For specific parameter performance, go to the testing room to use the instrument!" Wu Tong could not easily determine the material parameters before the test results came out.Her deduction is based on various superior conditions.

Throughout the entire experimental process, they have been as meticulous as possible and more refined and stable.As for the performance, it all depends on the material itself!Her estimate would be above 6000. Whether it can be achieved depends on whether the materials they prepare are up to par!
The first item of mechanical testing is basically the testing of tensile strength.The material is fixed on the instrument and the stretching machine starts working.

The data on the display skyrocketed rapidly, reaching the mark of 4 MPa effortlessly. It had just started, and it had already surpassed many alloy materials.The data did not stop. When they had just a few thoughts, the two thousand mark passed again. "Sure enough, it is a carbon fiber composite material that is admired by the world!" In this moment, it has surpassed the T[-] titanium aluminum alloy that they had previously hailed as an epoch-making aviation material, which was also produced by Wu Tong.

Of course, the properties of these two materials are different, so there is no need to compare them together.Metal alloys and carbon fiber materials cannot be replaced and must exist.

The 3000MPa mark and the 4000MPa mark have also been crossed in the eyes of everyone with increasing expectations. The data has been pulled here, and it has caught up with the level of similar carbon fibers in the world.

The 5000MPa mark has been sold again, which is the internationally advanced level data. The carbon fiber composite materials they prepared have reached the international advanced level and have surpassed the data of all similar products in China.

"It's 6000MPa, it's 6000!" Ruan Chengxu stared closely at the data of the stretching machine, his heartbeat was beating rapidly, and he could hear his own heartbeat. Such an extremely nervous state was worse than when he was young and worried about the teacher asking him questions. I was so nervous that I felt like my heart would jump out of my mouth.

However, he is not ashamed. What does the data of 6000MPa represent? It means that it has surpassed the international advanced level and achieved the world's first-class materials. They have to witness the birth of a super-class material, which is also the birth of a super material in a major sector of aerospace and aviation.

At this time, in the testing laboratory, apart from the calm junior sister, even the teacher was not much better than him, just calmer than him.A few others, not like him, clenched their fists, twisted their chests, and stirred the clothes on their chests. Everyone's eyes were fixed on the stretching machine data that was still rising steadily.

After more than ten hours of experiments from morning to night, even though the night was already deep and the morning light was about to come, their spirits were as high as if they had drank a large glass of sobering potion, without any signs of sluggishness. Feeling sleepy, they all stared at the stretching machine display in high spirits.

Finally, the tensile machine data ended at 7780MPa.It has broken through 2000, but it is still infinitely close to the figure of [-].This is their first experiment. If they repeat the preparation process more skillfully and control the process more accurately in the future, is it possible to break through the [-] MPa barrier and directly surpass the international advanced level of more than [-] MPa!

Everyone was staring blankly at the shining data on the display screen, their hearts boiling with excitement. It took a long time to react, but they were basically jumping up into excited cheers.

"Mr. Wu, Mr. Wu, 7780MPa! 7780MPa! It's almost [-]MPa. We succeeded. We broke through the world's leading level. Our carbon fiber composite materials are super first-class!" One after another, suppressed and restrained excited voices sounded one after another.Ruan Chengxu and Tao Ran took the lead and looked at Wu Tong.

Is this data already expected by Mr. Wu? Mr. Wu is their true god!

"Mr. Wu, Mr. Wu, you are the best, you are the most powerful!"

"You are great, too!" Wu Tong and the others calmed down a bit in excitement before praising with a smile. "I previously estimated that I could break six and touch seven thousand. It is because of your concerted efforts and thanks to the teacher's experienced supervision that we have achieved this transcendent data!"

"Let's move on to the next tensile modulus test!"
