The body armor that Xiao Yao intends to make is made of combined fiber fabrics, which has bulletproof functions.

Of course, there must be a difference between military body armor and Xiao Yao's own, Xiao Yao doesn't have to go to the battlefield, all body armor is not high, just be able to resist the Mauser 98k sniper rifle, which has played a good role in protection, and the only thing that can approach Xiao Yao may be a pistol, and small guns are easy to hide.

Military body armor may have to add some special steel or the like, at least it can carry large-caliber bullets on the body, although it is bulky compared to Xiao Yao's body armor, but the protective function is much higher, but Xiao Yao has found a material that is both light and harder, and since it is done, it is necessary to do the best to protect our military comrades.

In addition to nylon fibers and ultra-high molecular weight polyethylene fibers, Xiao Yao found other special fibers in space.

However, there is no plan to understand its practicability in depth, and Xiao Yao explained in the laboratory what aspects to start the experiment and what are the specific steps.

Pointing out these research directions allows researchers to go in this regard, due to the success of the research and development of the first few materials, now every researcher is like a chicken blood, and is full of enthusiasm to listen to Xiao Yao's command

Because of the existence of reference materials, it is not as difficult to develop as imagined, and these materials must be developed separately before they can start to make this kind of body armor.

"Now let's start brewing with a special liquid, and conduct experiments separately to see the final result, and we will use that method if the effect is better."

Xiao Yao commanded

"Got it, Professor Xiao." The cadets replied

Looking at the material that was about to be formed, Yan Xudong admired it very much, and said while recording the data: "Teacher, you have worked really hard for the cause of scientific research, you have not had a good rest since the beginning of the project, you are really a model for us to learn." ”

Xiao Yao coughed embarrassedly, he was as great as Yan Xudong said, but he just wanted to make a contribution to the scientific research of the motherland, so that these materials would not have to pay patent fees in the future.

Looking at Yan Xudong's adoring eyes, Xiao Yao still didn't explain, so as not to spoil a young man's beautiful fantasy.

After nearly three months, according to the trial and error guidance explained by Xiao Yao, the special D3O material was finally successfully researched.

D3O material in the normal state to maintain a relaxed state, soft and elastic, once violently hit or squeezed, the molecules immediately lock each other, quickly tighten and harden to digest the external force, forming a protective layer, when the external force disappears, the material will return to its original relaxed soft elastic state.

It can react differently to different shock situations in nanoseconds.

In fact, this is a non-Newtonian fluid substance with a viscosity completely different from that of liquids in Newtonian physical models, such as water and gasoline.

After testing and directing, it was proved that the change of the material after an impact is determined by the force of the impact.

That is, the harder the impact, the harder it becomes

This is the special bulletproof material that Xiao Yao wants, and the D3O material will be combined with nylon fiber and ultra-high molecular weight polyethylene fiber to make a composite combination and eventually become an ideal body armor.

None of the researchers in the Special Materials Project could believe that they had made such a thing.

They are just graduate students who have just left their studies, and they never dared to imagine that there is such material in the world.

Now they're getting it out of the way.

hugged each other and cried, and the special materials beyond the times became a reality with their efforts, and everyone was so excited that they could only express their feelings at the moment with tears.

After the first composite body armor was made, Xiao Yao made a difficulty, how to test its hardness without a gun.

"What's wrong with the teacher, are you dissatisfied?" Yan Xudong looked at Xiao Yao's expression and asked

"No, I want to test the hardness but I don't have a gun." Xiao Yao said embarrassedly

Before proving success, Xiao Yao didn't want to report it, so don't rejoice.

"Teacher, have you forgotten where we are, there may be nothing else, but there are still fewer guns."

Yan Xudong reminded

Xiao Yao was really busy with a pat of his head, there were basically guns here, and he was looking for a bicycle.

The trainees walked out of the laboratory together and walked towards the security department, which startled the comrades on duty, what is going on, intellectuals can't be something lost.

"What's wrong with Professor Xiao?" Captain Zhang Jie ran forward quickly, he was Xiao Yao's guard captain, responsible for Xiao Yao's life safety, he was also the captain here in the laboratory, everyone saw Xiao Yao and they walked towards the security department and hurriedly asked.

"Captain Zhang, that's it, we have developed a new type of body armor, and we want to test it with your gun." Xiao Yao pointed to the body armor he had just made and said.

Zhang Jie didn't dare to underestimate Xiao Yao's invention, and immediately arranged for two snipers to follow Xiao Yao and them to the shooting range for actual combat testing.

A stake dummy put on body armor and conducted a pistol shooting test at a distance of five meters, and after a bang, the trainees walked to the dummy to check, and there was no trace left on the body armor, and the bullet fell under the stake.

Yan Xudong clenched his fists very excitedly, and he couldn't stop the smile on his face, but the test had to continue.

Twenty meters away from the assault rifle for point firing, after a clattering sound, the inspection was carried out again, seeing that the students nodded again, Zhang Jie couldn't sit still, and quickly left to call the military region to report what kind of body armor they had done.

"We will be there soon to strengthen the security work, and we will protect all the safety issues of scientific research personnel, and there must be no problems." The voice on the other end of the phone said excitedly

"Yes." Zhang Jie stood upright and acted quickly, with five steps, one post, ten steps and one sentry, and the institute carried out martial law like an iron bucket.

The old chief received a call from the military region and said, "Are you sure?" ”

"The old chief is true, Comrade Zhang Jie saw it with his own eyes."

"Hahaha, good Xiao Yao, let's go to see the effect of this body armor immediately."

The old chief walked out of the office with a ruddy face, got into a military vehicle and went to the Fifth Research Institute.

Because it belongs to military supplies, this matter naturally also let several old generals know about it.

The Fifth Research Institute welcomed a number of generals in half an hour.

Seeing that the body armor made by the research institute was light and thin, and it was comfortable to wear on the body, they all looked at each other and didn't believe that it could be bulletproof.

"Practice tests the truth, and we will know if we test it ourselves." The old chief was the first to speak

The body armor was put on the body of the stake dummy again, and the old chief picked up the pistol and fired seven shots in a row, and then everyone surrounded him, one by one, dumbfounded, since there were no bullet marks left, his face turned from cloudy to sunny, and he stroked it gently, and his face began to get excited.
