"Leaders, there is something I have to say in advance, this helmet has an expiration date."

"Shelf life?" It's the first time I've heard this and I'm curious.

In the past, steel helmets had no shelf life, and when exposed to the sun and rain, at most the paint on the outside fell off, but aramid helmets are different!

"That's right, or the decay cycle, generally speaking, a five-year cycle." Qin Feng said: "The helmet that has just been manufactured now can only block 56 punches of direct fire in five years, but after five years, it can only block 79 punches of steel core bullets, and in another five years, it can only block 79 punch pistol bullets, and in another five years, it can only block 54 pistol bullets." ”

This must be made clear, otherwise five years later, when the troops come to find trouble for themselves, they will have to go in and squat or even eat peanuts.

Due to the material, aramid helmets cannot be used for a lifetime like steel helmets, let alone put into the war readiness warehouse as inventory, this thing has to be used after it is produced!

Pan Daqing's eyes lit up: "This can't be done!" Our troops are diligent and thrifty, and if they can't stop the bullets after five years, isn't it a waste? Your helmet is immature and must be improved! Our institute has rich experience, you can bring the technology to the institute, let's study it together, and strive to get it..."

"Make a hammer!" Li Runzhu interrupted him: "What's wrong with five years, if you put it for twenty years, won't you still be able to block 54 pistol bullets?" It's worth it, too! ”

The existing steel helmet is at most to block 54 pistol bullets, and the steel helmet made of this special material in front of you can prevent 56 rushes, and it can also prevent 54 after 20 years, what is there to be dissatisfied with?

"But..."

"But what? Our first-line troops will be issued with this kind of advanced helmet, after all, they are going to go to the battlefield, and after five or ten years, the helmet will be eliminated and worn by the second-line troops and used in turn, isn't it? Li Runzhu said: "If your research institute has the ability, you can research an advanced helmet by yourself, as long as it can block the 56 rush, we will purchase it in large quantities!" If you can't, don't compare here! ”

Pan Daqing's face turned red and he couldn't say anything.

"Now, the helmet problem has been solved, but, Xiao Feng, I remember you promised me that after this kind of helmet is developed, you will also study body armor, which can also block 56 straight shots?" Li Runzhu looked at Qin Feng with a pleasant face.

Body armor, blocking 56 straight shots? Are you kidding! Pan Daqing subconsciously wanted to speak again, but when the words came to his mouth, he didn't dare to say it.

Body armor was invented in the last century, and after witnessing the assassination of the mayor, the clergy at that time, Zigrin, was determined to develop a sacred equipment to protect the world: body armor, he tried various materials, and then made body armor out of silk, but unfortunately the sales failed repeatedly, otherwise the history of the world could be rewritten.

By the time of World War II, some people who did not need strenuous activity were also wearing body armor: simply placing steel plates on the front and back of the chest also saved many lives.

During the Cold War, countries were also developing advanced body armor, Lao Maozi was the most extravagant, and directly took out titanium alloy to make protective equipment, the effect was just, but the price was also high, and it could only be used by special forces.

When Kevlar material appeared, it became a trend to use this material to make soft body armor again, but at most, it was only to protect against pistol bullets, and it was only after the nineties that it was really able to resist rifle bullets.

At this time, hearing Li Runzhu's question, Qin Leader couldn't help but be curious there: "Is it also a helmet?" This material is really good, but the price is too expensive. ”

In fact, the country has also been developing body armor, in the fifties, in order to protect the safety of superior leaders, the relevant departments developed the first generation of body armor, using fiberglass, and in the sixties developed two kinds of body armor of fiberglass-chromium steel-boron carbide composite structure and aluminum alloy structure, which are used to equip car drivers who travel to and from the southern border.

In the 80s, a combination of aluminum alloy and nylon was used to create Type 81 body armor, which was relatively light and used to protect superior leaders.

However, none of these body armor can block 56 punches, and the helmet made of this special material in front of me is the first time to block bullets of this level, and now, the big guys can easily think that since they can make helmets, of course, they can also make body armor.

However, the price is certainly not low! Helmets are only 800 yuan, and body armor is not worth thousands?

"Yes, the price is too expensive, and we can't equip it in large quantities, and our research institute has developed two advanced bulletproof vests." Pan Daqing finally found a chance to speak: "These two are codenamed TF90-54 and TF90-79 respectively, using high-performance special bulletproof steel, which can block the shooting of 54 pistols and 79 submachine guns respectively. ”

"Can you block 56 punches?" Li Runzhu asked.

"This... Not yet. ”

"Then you talk about a hammer!" Li Runzhu glanced at him, and then looked at Qin Feng again: "Xiao Feng, when will this kind of body armor be made for us to open our eyes?" ”

"Once the equipment and raw materials are in place, it can be made in one day." Qin Feng said.

Equipment and raw materials? Leader Qin was a little curious: "Isn't it a helmet?" ”

"No, this material is too expensive, and we can reduce the cost of body armor to about four hundred yuan by using new materials."

"Really? That's great! Tell us what equipment you need, and we'll help coordinate! Leader Qin was very happy: "Xiao Feng, you have made great contributions to the troops, and the troops will always remember your contributions!" ”

"We are also for..."Qin Feng originally wanted to say that it was for the country, for the army, and for the soldiers to shed less blood on the front line, but when he glanced at Pan Daqing, he immediately changed his words again.

"In order to give outdoor sports more protection, when tourists go to climb the mountain, wear this kind of equipment, you don't have to be afraid of falling rocks on the mountain, your troops want to purchase it is your business, I have to declare, we are a civilian product."

It's outdoors again, it's mountaineering again! Wearing shoes to climb the mountain is reasonable, wearing a helmet to climb the mountain, are you not afraid of tiredness? It's better now, you actually have to climb the mountain in body armor! Pan Daqing was speechless.

Li Runzhu nodded on the side: "Xiao Feng, don't worry, if there is anyone shameless who dares to let you contribute these technologies in the name of the country and the army, you can call me and see that I don't have big ears to smoke him!" If you have the ability, you can do a research on yourself, you don't have the ability, and you want to rob others, Lao Tzu is the most disgusted by this kind of person! ”
