"Hello, Lin Gong, hello, it's not carbon fiber, it's a polyimide film material sent to us by a new supplier."

Faced with the middle-aged man's inquiry, Xu Yan turned around and saw that it was Lin Bicheng, deputy chief engineer of Aviation Technology International Holdings Group, who came with Minister Zhao Lin, and then quickly replied.

Lin Bicheng raised his eyebrows and asked curiously: "Polyimide material? I heard right, did you just say that the elastic modulus of this material has reached 10gpa?"

The implication is that he has never heard of polyimide materials that can achieve 10gpa elastic modulus.

"Yes, this is the result of a test of a material R&D manager in my hands."

Xu Yan answered, wondering in his heart: "Is this strange?"

For a polyimide film material, which is commonly referred to as pi film, Xu Yan basically uses dielectric constant, low temperature resistance, high temperature resistance, radiation resistance, etc. The elastic modulus is not too much concerned, and naturally it is not sensitive, so it is not clear what is strange about the elastic modulus of 10gpa.

What he is strange about is that the fy-02 sent by Feiyang New Materials actually measured a dielectric constant of 2.0, which means that the insulation performance of this fy-02 is far superior to any PI film on the market.

Generally speaking, the dielectric constant of this material is about 3.0, and other chemical elements are added, such as fluorine. In this case, the insulation performance of the pi film is far greater than that of most materials on the market.

The lower the dielectric constant of a material, the better the insulation performance of this material.

The insulating capacity in a vacuum state, the dielectric constant is expressed as 1.

The closer the dielectric constant is to 1, the stronger the insulation capacity is.

The addition of fluorine into the pi film will lose the environmental protection characteristics of the pi film material. In most places, fluorine is not allowed. The pi film sent by Fy-02, Feiyang new material, has a dielectric constant of about 2.0, and the environmental protection standards also meets the standards, which means that the chemical element fluorine has not been introduced. It can be imagined how powerful the performance of fy-02 is, no wonder the material R&D manager under his command said that the performance is inferior to similar products.

"Can you show me the test report and the product?"

Lin Bicheng became interested and couldn't help asking.

Lin Bicheng is in charge of the position of deputy chief engineer. Xu Yan is not sure what he does, but he also knows the other party's energy and professionalism in the field of mechanical materials.

"OK."

Xu Yan agreed and thought to himself: "Is this elastic modulus an amazing performance?"

He sent a message and asked his material R&D manager to take a little FY-02 material over, then opened the test report and handed the phone to the other party.

Lin Bicheng took the phone and looked carefully.

As soon as he looked in, Xu Yan found that Lin Bicheng's eyes lit up, and then the expression on his face gradually changed from calm to surprise, and then to a little excitement and shock.

After a while, Lin Bicheng reacted and returned the mobile phone to Xu Yan.

"Mr. Lin, this is the material I mentioned fy-02."

Xu Yan handed him the materials.

Lin Bicheng couldn't wait to take it, looking at the golden fy-02 materials of the shop with a eager look, stroked his hands, and said at the same time: "Director Xu, if it is convenient, please send me a copy of the test report and send it to my email?"

Xu Yan was completely unlucky and immediately replied: "Okay, Mr. Lin, please provide your email address and I will send it to you later."

Lin Bicheng quickly gave him his email address and asked again: "Which company's material is this?"

Xu Yan said: "It was provided by Feiyang New Materials. Let us verify the manufacturer used in mobile phone glass."

Lin Bicheng was stunned: "Feiyang New Materials? Is that Feiyang Optical Company sanctioned?"

Xu Yan briefly explained: "The one who was sanctioned was Feiyang Optics, and Feiyang New Materials is the parent company."

"So that's how it is."

Lin Bicheng then suddenly realized and said with a smile: "It seems that Feiyang New Materials is indeed extraordinary. I heard that it was an optical material that was sanctioned. Now, their R&D strength is not only optical materials, but also in the field of special engineering materials. I think this material has great prospects, not only for the manufacture of mobile phone glass, but should also play a major role in other fields."

Xu Yan smiled: "That's not something I can know."

Afterwards, Lin Bicheng left with a small roll of fy-02 materials in his hand.

Looking at his back, Xu Yan couldn't help but ask the Executive Minister next to him: "Lao Wang, which engineering field is this Deputy Chief Engineer Lin in charge?"

Minister of Executive Wang Lei is a master of all things. He knows the personnel relationship between TIME Group and the leading Aviation Technology International Holding Group.

Xu Yan is a straight man in science, relatively pure, and rarely combines this kind of gossip, and there are no traces of people who are engaged in administration.

Wang Lei did not disappoint him, and replied in a low voice: "I heard that it was a big-name engineer who participated in the manufacturing of aircraft."

Xu Yan was stunned: "Building an airplane? Are you teasing me? Will the big guy who builds an airplane come to our company?"

Wang Lei glanced at him sideways, snorted and said, "You can read the name of our company!"

“Aviation Technology International Holdings…”

Before he finished reading, Xu Yan was stunned and murmured to himself: "I still can't believe that the plane builders will come to our company for inspection? Are they here to relax?"

Little did he know that he was really guessing half of his idea.

Lin Bicheng does have the idea of ​​relaxing, and of course, he is more about looking for inspiration.

A key technology is currently stuck. Lin Bicheng led the team to public relations for a long time but couldn't answer it, so he simply gave the team two days off and ran out for a walk. Sometimes, technical research cannot be done hard, and it also needs to be edifying.

"Boss, continue to do the next single-body test. Do I want to try it out if I get a sample?"

After accompanying him, Xu Yan returned to the office and found his material research and development manager to ask for details. After the introduction, the other party suddenly came up with such an idea.

Xu Yan was silent for a moment and fell into thinking.

Seeing his reaction, the material development manager continued: "This is the first time I have seen such a powerful pi film. I am confident that this material will surprise us."

Xu Yan nodded subconsciously, then made a decision and told him: "You are right, save some time, good materials will not wait for anyone. I believe Feiyang New Materials also recommend this material to other mobile phone glass manufacturers. In this way, Xiaomai's newly developed dual-hole screen is now arranged to use this material to verify it. It is used on the LCD screen, not on the OLED screen."

The LCD screen has now become a mid-to-low-end model. The wheat company will not be too confused if it is seizing the market through volume.

The real core must be oled.

Xu Yan would rather choose to be more conservative.
