It's not that the backbones present don't want to say it, but they really don't know what to say, you must know that the operating table in front of Bai Yi is made of a whole steel plate, although it is not as hard as armor steel, but it is not a few pieces of cloth that can be hard after being coated with several layers of paste.

But as a result, Bai Yi held the rough adhesive, but it was like holding a sledgehammer in his hand, wantonly hammering towards the current steel console, making a muffled sound of "bang ~~", as a result, the adhesive in Bai Yi's hand was not only unharmed, but the steel panel in front of him was smashed out of a large depression.

Seeing that everyone present here was all surprised, and said in their hearts, what the hell is this, how can it compete with steel, not to mention, the weight is also very light, because everyone can see it, Bai Yi can easily lift the adhesive the size of the operating table with only one hand, raise it high, fall in the middle, and lift the weight effortlessly.

Strong as steel, light as a feather!

The people present are all veterans of the military industry, not much, just these two points are enough to shock the audience!

"This ...... This...... This should be the latest lightweight material! ”

I don't know how long it took, a backbone finally couldn't help it, and shouted excitedly, and this sentence was like a firework that exploded in the water, and everyone suddenly broke out into an irrepressible discussion, not only that, but some curious backbones rushed over, surrounding Bai Yi, or carefully touching, or carefully observing, or simply smashing with his fist twice without pity, or holding his eyes to seriously observe every detail of it, trying to find some clues from it.

At this moment, a female team member with two braids suddenly thought of something, looked at Bai Yi with a notebook, and asked timidly: "Team leader Bai, you just said that this thing is called fiberglass?" ”

"That's right, this thing is called fiberglass!" Bai Yi took the piece of glass fiber reinforced plastic that had just been prepared from the hands of a backbone, put it on the operating table with a "bang~~", looked at his work and nodded with satisfaction: "More precisely, it should be called epoxy resin fiberglass!" ”

"Epoxy?"

Feng Chong, who was at the back of the crowd, couldn't help but be shocked when he heard Bai Yi's words, and Zhang Yi, who was standing beside him, saw that something was wrong, and quickly asked, "Do you know epoxy resin?" ”

"I haven't seen the specific object, but I've seen it in the book, and it's a more advanced resin material than phenolic resin!"

"Phenolic? Shuo material? ”

Although Zhang Yi thinks he is honest, but he is not a lonely person, epoxy resin he may not know what it is, but phenolic resin he knows that this kind of proper noun that sounds very tall to others, in fact, there is a more understandable name, that is, Shuo material, but in chemical preparation, it needs a more professional expression, so the plastic is called phenolic resin.

Speaking of which, Zhang Yi knew that phenolic resin was also a very fortuitous opportunity, that was in 1921, when Zhang Yi was still a child, he followed his father to create a beach, and Zhang's father, who wanted to break out of the world, but because of bad luck, he achieved nothing, and entered a factory called Desheng Chemical Products as a worker by mistake.

It also happened that this Desheng chemical factory had just obtained a patent for the preparation of Shuo material from the United States, thus becoming the first manufacturer in China to produce Shuo material, because of this, Zhang Yi has been full of phenolic resin, Shuo material and other topics since he was a child, so when Feng Chong mentioned phenolic resin, Zhang Yi can get to the point at once.

Feng Chong naturally didn't know about Zhang Yi's past, and his friend knew the relationship between phenolic resin and Shuo material, although he was a little surprised, but he couldn't help but admire and give a thumbs up: "That's right, phenolic resin is Shuo material, and epoxy resin is a more advanced plastic product than phenolic resin, I remember when I was studying chemistry at Fu University, I saw the introduction of epoxy resin, and the western developed countries had just been successfully trial-produced at that time, and I only paid attention to it at that time, but I didn't expect it to ...... today."

As he spoke, Feng Chong's words suddenly stopped, and he looked at Bai Yi who was talking and laughing among the crowd in a daze, and at this time, Zhang Yi had long since stopped paying attention to Feng Chong, took out the notebook he carried with him, and recorded every word Bai Yi said......

"The lesbian just said is right, epoxy resin and phenolic resin are essentially the same, is a kind of material, but the chemical structure is completely different, of course, some people may ask, the same material, then this FRP can use phenolic resin as a binder?

The answer is naturally yes, but because of the chemical structure characteristics of phenolic resin, the internal molecular structure void is larger, which will lead to cavitation between the glass fibers, which requires a special press to extrude, but despite this, this kind of FRP can only be used for civilian use, if it is used in weapons and equipment, its mechanical properties are still somewhat unacceptable.

Epoxy resin is different, because of its unique molecular structure, can make the glass fiber completely closed, after solidification, whether it is hardness, tensile force or durability are very good, if amine chemicals are added to it, it can also play a flame retardant role, so, the glass fiber reinforced plastic processed by epoxy resin can be applied to weapons and equipment, so as to reduce the overall weight of the equipment at the same time, to ensure the reliability and durability of weapons and equipment! ”

"Phenolic resin we know, but epoxy resin is a new product developed in the United States in the 40s, according to the information, it is quite difficult to prepare, and countries with a weak foundation cannot produce it at all!"

As soon as Bai Yi's words were finished, before the people around him could focus their reverent eyes on him, the timid ponytail female backbone just now used her soft but sharp words to interrupt everyone's gaze......

"As far as I know, our country does not have the large-scale production capacity of epoxy resin, and it can be seen from the words of the team leader just now that epoxy resin is the core preparation material of military FRP, if you want to be applied on a large scale, it must be mass-produced, so as to reduce costs at the same time, batch become the core material of weapons and equipment.

Otherwise, only one or two samples will not be of great value, which can only show that we have mastered the preparation theory of this technology, which is still far from large-scale production and application...... Forehead...... Big guy, why are you looking at me like that, I ...... I...... Am I wrong? ”

The female backbone with a ponytail spoke very smoothly at first, although her voice was still not loud, but she could talk and speak, but she felt that something was wrong, because everyone, including Bai Yi, focused their indescribable eyes on her, which made the female backbone who was not good at words panic for no reason, but before she could finish her words, Bai Yi, who was standing opposite him, nodded without hesitation with a gentle smile: "That's right, you're right!" ”
