"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, the team collaborated and worked together many times. Several core experimental personnel on the operating table have been able to cooperate with Wu Tong like an arm and a finger. The experiment continues step by step strictly according to Wu Tong's requirements or under Wu Tong's operating settings.
Anodic electrode oxidation and pulse electrification process the surface to form a better contact surface.
While gradually heating to 50°C, the carbon filaments are washed with water by the dipping method to prepare for sizing, followed by further sizing to form a protective film on the surface of the carbon filaments.
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 more compact and enhances stability. It is also the key to achieving 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, they will synthesize the required strong oxygen resin under Wu Tong's instructions.
Wu Tong further confirmed the test data and found that it matched the reinforcement material she had deduced.
So far, the progress has been smooth. The rigorous atmosphere in the laboratory is accompanied by the joy of forging ahead.
The prepreg process begins. Cheng Huanan oversees the operation, providing support and ensuring the precision of the prepreg. The preparation of carbon fiber prepreg is a key step in the production of carbon fiber products, impacting their performance and quality.
The amount of prepreg and the degree of impregnation 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 negligence.
"Keep it cold!"
············
Pre-oxidation treatment, high and low temperature carbonization take turns, and various chemical reactions are intertwined, making people almost dizzy...
Finally, after some winding and unwinding processing, they obtained a 48K large-bundle carbon fiber material.
Holding it in their hands, the extremely light and thin feel and weight made several experimenters stare intently at the material in front of them, which was prepared by them under the leadership of General Manager Wu.
Although they haven't yet used testing equipment, they all have a long history in materials science, having spent at least ten years studying it. Visual inspection is one way to determine if a material is good or not.
"Boss Wu, have we succeeded?" Tao Ran's voice trembled as he took a step back before speaking. He knew the material was so strong that even if everyone present stretched it simultaneously, they wouldn't be able to tear it apart. However, the caution he felt towards this new material compelled him to act with caution.
"The preparation was successful. Let's go to the testing room and test the specific parameters!" Wu Tong couldn't easily determine the material parameters before the test results came in. Her deduction was based on various favorable conditions.
Throughout the entire experimental process, they've strived for meticulous refinement and stability. As for the performance, it all depends on the material itself! Her estimate is over 6,000, but whether or not they can achieve that depends on the quality of the material they produce.
The first mechanical test is basically a tensile strength test. The material is fixed on the instrument and the tensile machine starts working.
The data on the display screen soared and jumped rapidly, effortlessly crossing the 1,000 MPa mark. Just starting out, it had already surpassed many alloy materials. The data didn't stop, and in the time it took them only a few thoughts to cross the 2,000 MPa mark again.
"It is indeed the carbon fiber composite material 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 two materials have different properties, so there's no need to compare them. Metal alloys also have their own unique qualities that carbon fiber materials can't replace.
The 3000MPa and 4000MPa marks were also crossed amid the increasingly expectant eyes of the crowd. At this point in the data, it has caught up with the level of similar carbon fibers in the world.
The 5000MPa mark was sold again. This 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 available in China.
"6000MPa, 6000!" Ruan Chengxu stared at the data of the stretching machine, 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 about 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 and aviation industry.
In the testing lab, besides the calm and composed junior sister, even the teacher wasn't much better, just a bit calmer. The others, like him, clenched their fists, twisted their chests, and ruffled their clothes. Everyone's eyes were fixed on the steadily rising data from the stretching machine.
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 break, their spirits were as high 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.
Ultimately, the tensile test machine reached a reading of 7780 MPa. It surpassed 7,000 MPa and was still incredibly close to 8,000 MPa. This was their first experiment, and if they become more proficient in the preparation process and more precise in their approach, they might be able to break through the 8,000 MPa barrier and surpass the internationally advanced level of over 2,000 MPa.
Everyone stared blankly at the flashing data on the display screen, their hearts boiling with excitement. It took them a while to react, and most of them jumped up and cheered excitedly.
"Mr. Wu, Mr. Wu, 7780 MPa! 7780 MPa! Almost 8,000 MPa! We succeeded! We've surpassed the world's leading level. Our carbon fiber composite materials are top-notch!" One after another, suppressed yet restrained voices echoed in succession. Ruan Chengxu and Tao Ran took the lead and looked at Wu Tong.
Was this data already expected by Mr. Wu? Mr. Wu, they are really a god!
"Boss Wu, Boss Wu, you are the best, you are the most powerful!"
"You guys are amazing, too!" Wu Tong and the others, their excitement having calmed down a bit, smiled and praised. "I had estimated we could break six, perhaps even touch seven thousand. It's thanks to your concerted efforts, and thanks to the experienced teacher's supervision, that we've achieved this transcendent figure!"
"Let's move on to the next tensile modulus test!"
