Chapter 256 is released

"Apply... stretching force!" Wu Tong once again reported a force parameter, in order to achieve the orientation degree she wanted.

With Wu Tong as the absolute core, team collaboration, and multiple runs-in, several core experimental personnel on the operating table have been able to cooperate with Wu Tong like an arm or a finger. Strictly following Wu Tong's requirements, or under Wu Tong's operating settings, the experiment continues step by step.

The anodic electrode is oxidized and the pulsed current is applied to treat the surface to form a better contact surface.

The carbon filaments are washed with water by the dipping method while gradually heating to 50°C to prepare for sizing, followed by further sizing to form a protective film on the surface of the carbon filaments.

Carbon filaments are brittle materials. Sizing changes the surface properties of carbon filaments, increases their wear resistance, improves their bundling properties, and enhances their stability. It is also the key to achieving the superb 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, they will synthesize the required strong oxygen resin under the instructions of Wu Tong.

Wu Tong further confirmed the test data and found that it matched the reinforced materials she had deduced.

So far, the progress is going smoothly. The rigorous atmosphere in the laboratory is accompanied by the joy of forging ahead.

The prepreg process begins. Cheng Huanan watches the operation, follows up and assists, and controls the precision 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 wetting need to be carefully controlled. At this point in the experiment, more than 70% of the process has been completed, and there is no room for any negligence.

"Keep it cold!"

············

Pre-oxidation treatment, high and low temperature carbonization, and various chemical reactions interweave and interweave, making people almost dizzy...

Finally, after some wire-winding and wire-releasing processing, they obtained a 48K large-bundle carbon fiber material.

Holding it in the hand, the extremely light and thin feel and weight made several experimenters stare intently at the material in front of them that they had prepared under the leadership of General Manager Wu.

Although they haven't used any testing equipment yet, they all have been working in materials for a long time. From the initial learning to now, it has been at least ten years. In fact, the quality of materials can be judged by naked eye observation.

"Boss Wu, have we succeeded?" They have successfully developed it, Tao Ran's voice trembled a little, and he took a step back before speaking. Even though he knew that the strength of this thing might not be able to be torn apart even if everyone present stretched it at the same time, he still couldn't help but take action when faced with this new material.

"The preparation was successful. Let's go to the test room to test the specific parameters!" Before the test results came out, Wu Tong couldn't easily determine the material parameters. Her deduction was based on various favorable conditions.

Throughout the entire experimental process, they have tried their best to make it as precise and stable as possible. As for the performance, it depends on the material itself! Her estimate is that it will be above 6,000. Whether it can be achieved depends on whether the materials they prepare are up to standard!

The first item of mechanical testing is basically the tensile strength test. The material is fixed on the instrument and the tensile machine starts working.

The data on the display screen jumped up and down quickly, and the 1,000 MPa mark was easily passed. It had just started and had already surpassed many alloy materials. The data did not stop, and in the time it took them to think about it, the 2,000 MPa mark was passed again.

"It is indeed the carbon fiber composite material that is highly praised by the world!" In just a moment, it has surpassed the T4 titanium-aluminum alloy that they had previously praised as a groundbreaking aviation material, 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 also have their own needs that cannot be replaced by carbon fiber materials.

The 3000MPa and 4000MPa marks were also crossed amid everyone's increasingly expectant eyes. At this point in the data, it has caught up with the level of similar carbon fibers in the world.

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

"6000MPa, 6000!" Ruan Chengxu stared at the data of the stretching machine closely, his heart beating so rapidly that he could even hear his own heartbeat. This extremely nervous state was several times more stressful than when he was a child and worried about the teacher asking him questions. He felt like his heart was going to jump out of his 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 world-class material. They are about to witness the birth of a world-class material, a super material that is crucial to the aerospace industry and a major sector.

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

From morning till night, they endured more than ten hours of experiments. Even though it was late at night and the dawn was about to come, their excited spirits at this moment were as if they had drunk a large glass of stimulant. Without any lethargy or sleepiness, they all stared at the stretching machine display with alertness.

Finally, the tensile machine data ended at 7780MPa. It broke through 7,000, and was still infinitely close to 8,000. This was their first experiment. If they were more proficient in repeating the preparation process and more precise in the process, would they be able to break through 8,000 and directly surpass the international advanced level of more than 2,000 MPa?

Everyone stared blankly at the flashing data on the display, their hearts boiling with excitement. It took them a long while to react, and most of them jumped up and cheered excitedly.

"Mr. Wu, Mr. Wu, 7780MPa! 7780MPa! Almost 8,000MPa, we succeeded, we broke through the world's leading level, our carbon fiber composite materials are top-notch!" One after another, suppressed and restrained excited voices rang out one after another. Ruan Chengxu and Tao Ran took the lead and looked at Wu Tong.

Is this data? It was already expected by Mr. Wu. Mr. Wu, they are really gods!

"Boss Wu, Boss Wu, you are the best, you are the best!"

"You are also great and amazing!" Wu Tong and the others smiled and praised after their excitement calmed down. "I had estimated that we could break six and touch seven thousand. It is because of your concerted efforts and the teacher's experienced supervision that we have achieved this transcendent data!"

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