Chapter 216 Bulletproof Test
The next day, New Year’s Day, the streets throughout the factory and the Workers’ Cultural Palace were decorated with lights and colors, and the scene was filled with joy everywhere.

Except for the workers on duty, most of the workers in the factory have already gone on holiday, but Xu Qiang came to the laboratory as usual.

After the successful development of aramid paper, Xu Qiang also had to test this batch of samples. He could have scheduled it until after New Year's Day, but in the end he couldn't contain his excitement and prepared to complete the testing work alone.

With the help of advanced instruments in the laboratory, Xu Qiang completed the preliminary testing of this batch of aramid paper in just one morning. The results showed that the performance basically met expectations.

However, compared with the indicators of the samples of the aramid paper project that Xu Qiang participated in later generations, there is still a certain gap. There are two main reasons. One is that the equipment performance is not as good as that of later generations. The other is that the short fibers used to support the aramid paper structure are not cut in place. Since there is no special machine, the short fibers are of different lengths, which affects the strength of the aramid paper to a certain extent.

Therefore, the aramid paper made by Xu Qiang this time is only equivalent to the first-generation product of DuPont in the United States. Compared with the third-generation product in later generations, its performance is exactly half as bad.

But even so, this first-generation aramid paper is still an advanced composite material in the world and its uses are very wide.

After completing the testing of basic projects in the morning, Xu Qiang took dozens of aramid paper samples, rode his scooter, and went directly to the security department of the factory.

"Xu Qiang? Why are you here during the holidays instead of staying at home?"

Seeing Xu Qiang riding a motorcycle directly into the security department's compound, the section chief on duty, Wu Zhijun, walked out of the house and asked in surprise.

"I came here to find you." Xu Qiang jumped off the motorcycle and said with a smile.

"Looking for me? Why are you looking for me?"

"I need your help with something..." Xu Qiang said, taking out a thick stack of aramid paper from his sidecar and said to Wu Zhijun, "I want to test the bulletproof ability of these papers. I wonder if Section Chief Wu is available..."

These days, the security department of a state-owned enterprise is equivalent to the "police station" of the entire factory. It has great power. The security personnel inside are all equipped with guns, and they can step in to resolve any trivial matter.

Because the Security Department is in charge of the security of the entire factory, it also has a special armory that stores pistols, bullets, rifles, grenades and other weapons.

As a large third-line arsenal with 10,000 employees, the Shengli Machinery Factory has even more equipment. It is said that it even has anti-aircraft guns. They are pulled out for training at fixed months every year, and can carry guns directly to the battlefield in case of war!

Although the control over military equipment has become slightly stricter in the past two years, as the deputy chief of the security department, Wu Zhijun still has the right to use firearms.

"Isn't this a waste? Such good paper was broken into pieces by just one shot. What a pity." Wu Zhijun said with a frown.

When he was young, Wu Zhijun was the deputy company commander of the local militia company. He had very strong military qualities and was familiar with the performance of various firearms. In his opinion, the protective ability of paper was basically slightly stronger than that of wood. If hit by a bullet, the powerful kinetic energy could penetrate it instantly.

"This is not ordinary paper. It can be used to make bulletproof vests." Xu Qiang took out a piece of aramid paper, handed it to Wu Zhijun, and said, "This is the new product I developed. One of the product tests includes bulletproof performance. The factory director also agreed to this..."

"Are you serious?" Wu Zhijun's face turned serious when he heard Xu Qiang say that.

The fact that Xu Qiang was developing new products was known to the entire factory, and during the meeting, Liu Biao did say that all workshops and departments should cooperate with Xu Qiang's project development. There is no doubt about this.

Besides, Xu Qiang is now the head of the department. Since he said so, the Security Department must cooperate.

"Why else would I be here during the holidays?" Xu Qiang smiled and continued, "Actually, the test method is very simple. You just need to design these papers with a pistol and a rifle. If you're quick, it will be done in a few minutes."

"Okay, wait a moment." Wu Zhijun said, then turned around and went back to his office.

After a while, when Wu Zhijun came out again, there was a holster on his waist.

“Test it here?”

"Get on your bike and I'll take you to a shooting range."

"Okay!" Xu Qiang nodded, then rode on his scooter, took Wu Zhijun with him, and quickly left the Security Department compound.

More than ten minutes later, under the leadership of Wu Zhijun, Xu Qiang came to an open space in the back mountain.

This is actually the place where the local militia trained in the past. There are warning signs all around, and you can vaguely see white lines drawn with lime. There is also a small hill in the distance, which can be used to shoot chest ring targets.

After the two men discussed it, Xu Qiang took out more than ten sheets of aramid paper, found a small tree, and then used string to tie the more than ten sheets of aramid paper firmly to the tree trunk.

The next moment, Wu Zhijun pulled out a black pistol from his holster.

This is a standard Type 1930 pistol, a replica of the former Soviet Union's TT1933/1954 pistol. It was finalized in and is the most produced and equipped pistol in China. In the s, almost all public servants were equipped with this type of pistol.

The Type 7.62 pistol uses bullets. The characteristics of this type of pistol are high kinetic energy, loud gunshot, and extremely strong bullet penetration, but poor stopping power. As a result, when the police are on duty, the robbers are often shot several times but still able to escape or even fight back. Moreover, the strong kinetic energy makes it easy for the bullets to ricochet, which is also very dangerous.

But this pistol is a very good choice for testing the bulletproof ability of aramid paper.

"Stand aside!" Wu Zhijun motioned Xu Qiang to stand further away, then opened the safety of his pistol. The next moment, he raised his gun and aimed, with Wu Zhijun's posture being quite standard.

"boom!"

The moment Wu Zhijun pulled the trigger, dazzling flames gushed out from the muzzle and a huge noise echoed throughout the valley.

The bullet hit the center of the paper almost exactly, and a faint white smoke rose up.

"Great!" Seeing this, Xu Qiang gave Wu Zhijun a thumbs up, and then the two of them quickly walked towards the paper target.

"Eh...this...this is impossible?"

Wu Zhijun saw the dent in the center of the paper target at a glance, but what shocked him was that the bullet was embedded in the dent and did not penetrate it!
Wu Zhijun was quite familiar with the performance of the Type 54 pistol. You know, this pistol had great kinetic energy and penetrating power. Not to mention this stack of papers, it could even penetrate a steel plate a few millimeters thick easily!
At this time, Xu Qiang untied the rope and checked the penetration position of the bullet.

"One, two, three, four, five... thirteen, fourteen!" Xu Qiang was surprised and said, "It's worthy of being a Type 54 pistol. It can actually penetrate eleven pieces of paper!"

Generally speaking, the inner interlayer of aramid bulletproof vests will overlap dozens of aramid paper or aramid cloth. The number of layers will vary depending on the level of protection. According to my country's police bulletproof vest standards, soft bulletproof vests can reach a maximum of level 4, which means that they can block most pistol and submachine gun shooting from 5 meters away.

Level 2 soft bulletproof vests generally have twenty-four layers of aramid material, level 3 has thirty-two layers, and level 4 has forty layers.

Xu Qiang's batch of aramid paper is actually thicker than standard aramid paper, and its bulletproof ability is naturally stronger. If it were based on the standard paper thickness, it should be able to penetrate more paper.

But in any case, there is no problem in using this kind of paper to make soft bulletproof vests, and it is very light and can be worn freely.

"Are you kidding me? How come it only penetrated eleven pieces of paper?" Wu Zhijun widened his eyes and began to check the position of the bullet.

Wu Zhijun separated the papers and took out the bullet. When he saw that the papers at the back were completely intact, he could not believe his eyes.

At this moment, Wu Zhijun realized that this paper was extraordinary.

"Let me try a few more shots!"

At this time, Wu Zhijun had obviously been struggling with the aramid paper. He really couldn't believe that this seemingly ordinary paper could actually block the bullets of the Type 54 pistol!
Afterwards, Xu Qiang tied the aramid paper to the tree again, and Wu Zhijun opened the safety of the pistol again.

"Bang! Bang! Bang!"

This time Wu Zhijun fired three shots in a row. The kinetic energy of the bullets was so great that the small tree began to tremble slightly.

This time, the bullet still did not penetrate all the paper. The bullet head was embedded in it, and there was not even any sign of burning on the edge!
Wu Zhijun has been playing with guns for more than ten years, but this is the first time he has seen such an outrageous thing.

Seemingly unwilling to give up, Wu Zhijun hesitated for a moment and then pulled the trigger again.

"Bang bang bang!"

After the entire magazine was emptied, the rope holding the aramid paper began to bear the weight and broke, and the paper instantly scattered all over the floor.

The several pieces of paper on the surface had been completely torn apart by the powerful impact of the bullet, but there was no trace of a bullet mark on the tree trunk, and the bullet was still embedded in the paper.

At this moment, Xu Qiang finally breathed a sigh of relief, and Wu Zhijun was completely convinced.

"This thing is quite interesting. It seems that it can really be used to make bulletproof vests." Wu Zhijun said to Xu Qiang with approval.

"If I meet someone as good at shooting as you, no matter how many bulletproof vests you wear, it will be useless." Xu Qiang said with a smile.

"Hahaha! That's for sure." Wu Zhijun laughed when he heard that.

"It's time for dinner. Let's go. I'll treat you to dinner today." Xu Qiang was in a good mood at this time and said to Wu Zhijun.

"No restaurants are open on New Year's Day, so why don't you just go back to our security department? I have a bottle of good wine here, and I'll cook two side dishes, and we can eat and chat."

Ever since Xu Qiang was admitted to university, Wu Zhijun had wanted to invite him to dinner. Since they happened to meet today, he simply extended an invitation.

"Okay! Let's celebrate New Year's Day together!" Xu Qiang nodded with a smile.

The next moment, the two of them got on their motorcycles and quickly left the shooting range with bursts of engine noise...
