Chapter 1012 Mobile Office (Part 1)

Because of the plane collision incident, Guo Tailai even postponed the cooperation with Mr. Zhang of FAW for a month, allowing Mr. Zhang enough time and the company's marketing personnel to fully investigate the market demand.

The change of the bulletproof material this time is to add a one-centimeter-thick liquid bulletproof material and a composite armor mixed with double-layer graphene on the basis of the composite armor used in the T-head of Dahongqi. The bulletproof effect is even better, but the weight increase is not. not much. In addition, there is a pop-up grille armor that can usually be folded and hidden in the roof area.

The space of Dahongqi's car is limited, so it can only find a way to improve it. Compared with the armored bus, the space is much larger. The roof of the car with a height of at least four meters is enough to allocate a few tens of centimeters of space to install these grille armors.

The test of the armor material is very simple and rough. It is to shoot directly with standard equipment and ammunition. There is no skill, and it is a violent attack.

The 25mm armor-piercing projectile has no problem at all, and the 35mm armor-piercing projectile still cannot penetrate the thickened composite armor within 100 meters.

Next, is the appearance of a big guy, PGZ88 double-barreled 37mm self-propelled anti-aircraft gun, armor-piercing projectile, a distance of 100 meters. In the case of on-site observation and video recording by several staff members of the Central Security Bureau, the armor-piercing shells fired by twenty rounds of 37mm anti-aircraft guns only caused the deformation and protrusion of the bulletproof material, but still failed to penetrate the bulletproof plate.

Next, there seemed to be no intermediate-caliber weapons, and then the armor-piercing ammunition fired by a Type 59 57mm anti-aircraft gun directly penetrated the bulletproof material, leaving a small hole through it.

"Will our bus drive to a place where this weapon is aimed at?" Guo Tailai looked at the result speechlessly and asked the staff in charge of the test.

Obviously this is impossible, but those who do security work wish that the armor protection performance is as strong as possible, and wish that they can directly surpass tanks. Even though he knew he wouldn't be in that dangerous situation, he couldn't help but want better performance.

"Can't it be thickened again?" The leader of the working group asked hopefully.

"It's already 20 tons empty. Many ordinary bridges and roads can't bear this weight." The limit is that it is a 12-meter-long bus with a total of six sides of armor. If the windows are removed, the surface area will be more than 100 square meters. If it is thicker by one centimeter, it will add more than one cubic meter of material. Even if it is titanium alloy, it would cost four or five tons!

"Add another centimeter to the thickness." The team leader still demanded after pondering for a while: "Half a centimeter of liquid bulletproof material, half a centimeter of composite armor, the total weight will never increase by more than five tons, much lighter than those large vehicles, Ok?"

Adding one centimeter will add at least 30% more safety factor. Guo Tailai also understands the thoughts of the team leader and the others. Guo Tailai thought more about the performance of the car, the top speed must be close to 200 kilometers per hour, right? As a result, the team leader shook his head directly, no need, a maximum speed of 150 kilometers per hour is enough. And on the bus, pop-up grille armor can be installed on the top, and a few remote-controlled machine guns or howitzers for counterattack can be installed in other suitable parts for counterattack. This speed is enough.

Once you grit your teeth, there is nothing wrong with it, plus! Guo Tailai hurried back to the studio, spent another day processing a batch of armor plates for testing, and came to the shooting range to test again.

It is not so easy for these bulletproof materials to be tightly combined, and Guo Tailai's processing methods also played a big role in it. Both the support and the bonding required special techniques. Guo Tailai insisted on processing the 500-layer graphene bulletproof layer for the extra one-centimeter gap. Except for Guo Tailai, almost no one could do it.

The thickness of the thickened bulletproof plate has reached 5.5 centimeters, which is a full two centimeters thicker than the 3.5 centimeters on the big red flag. Among them, the liquid bulletproof material has been thickened by a full 1.5 centimeters, 1,500 layers The double-layer graphene is used as the skeleton. Just the addition of this non-Newtonian fluid makes some armor-breaking bullets that can only target homogeneous armor completely useless. The armor material vibrates to the point of shattering, but these shock waves are absorbed by several layers of liquid bulletproof material and do not generate enough waves to shatter the inner armor.

Of course, no matter what kind of ammunition, after the caliber exceeds a certain value, there is no such thing as whether it can be bulletproof. Caliber is justice!

During the test again this time, although the armor-piercing projectile fired by the 57mm anti-aircraft gun still successfully penetrated the bulletproof plate, it was firmly embedded in it and failed to continue to cause lethality.

Seeing this scene, the leader of the working group finally showed a smile, which made Guo Tailai shake his head endlessly.

The next step is to test the RPG's attack after adding the grille armor. Guo Tailai doesn't need to explain the principle of the grille armor against RPG attacks. With this thing, 50% to 60% of the RPG's attack can be caught by the grille. If the attack power is lost, the rest just hit the grille and the explosion emits a metal jet with a 50% probability that the jet will be deflected, and the grille armor is at least 30 centimeters away from the main armor, and the RPG's best The shooting height does not exceed the focal point by three to five centimeters. With such a long distance, the power is further reduced.

During the test, at least five RPG rounds were fired, four of which were caught in the grid, and one hit the grid to detonate, and the metal jet hit the armor plate. But this time, the 1.5-centimeter liquid bulletproof layer combined with the 1,500-layer graphene skeleton played an important role. The powerful metal jet only broke through the armor plate, but it didn't break through. It was also stuck in the bulletproof plate.

Seeing this result, everyone breathed a sigh of relief. When Guo Tailai looked at the leader of the working group again, the leader nodded for the first time: "It's ok!"

Now that the test has passed, the next step is naturally to start manufacturing. At the beginning, the leader of the working group wanted to estimate the cost of a car, but after seeing the materials and processing technology of those bulletproof plates, he stopped doing such futile things. It doesn't make sense to count them out. Except for Guo Tailai, no one else can make such bulletproof materials. To put it bluntly, this car is still a few unique cars, just like the T prefix of Dahongqi.

In the first half month, Guo Tailai didn't stop much. In addition to the purchases arriving one after another, Guo Tailai has already built some basic components, and now he is waiting for the final processing of the bulletproof plate.

When the eyes of the people of the whole country and the people of the world are focused on the gorgeous game of the South China Sea incident, Guo Tailai completely completed the production of three armored buses at the end of April.

Three black-painted armored buses lay quietly in the yard as soon as the studio entered the gate. The markers are shining brightly.
