Chapter 506: Mobile office (on)

Because of the collision incident, even the cooperation of FAW Zhang was pushed forward by Guo Tai for a month, so that Zhang had enough time and the company's market personnel to fully investigate the market demand.
This time, the bulletproof material was changed by adding a one-centimeter thick liquid bulletproof material and a double-layered graphene-composite composite armor to the composite armor used in the T-head of the Dahongqi. The bulletproof effect is even better, but the weight increase is not much. In addition, it is usually able to fold the pop-up grille armor hidden in the roof area.
The red flag has limited space, so it can only be improved. The space of the armored bus is mostly compared. At least four meters of the car roof is enough to divide the space of tens of centimeters to install these grille armor.
The testing of armor materials is very simple and rude. It is directly armed with standard equipment and ammunition. There is no skill, it is completely violent.
25mm armor-piercing projectile, no problem at all, 35mm armor-piercing projectile, still can not penetrate the thick composite armor within one hundred meters.
Next, it is the appearance of a big guy, PGZ88 double-tube 37mm self-propelled artillery, armor-piercing projectile, 100m distance. In the case of several central guards' staff observations and video recordings, the armor-piercing projectiles fired by twenty 37mm anti-aircraft guns only caused the deformation of the bulletproof material, but still failed to penetrate the bulletproof board.
Next, it looks like there is no medium-calibre weapon, and then a 59-type 57mm anti-aircraft armor-piercing ammunition directly penetrates the bulletproof material, leaving a small hole to penetrate.
"Our bus will drive to where there is such a weapon?" Guo Tailai looked at the result silently and asked the staff responsible for the test.
Obviously this is impossible, but to do the security work, the better the armor protection performance, the better, hate can not directly exceed the tank. Although I know that I will not be in that dangerous situation, I still can't help but want better performance.

Can't you thicken it any more?
the team leader asked with full enthusiasm.
"This is already 20 tons of empty cars. Many ordinary bridges and roads can't bear this weight." Guo Tailai is also no way. As long as they work with them, they hope that the thicker the armor, the better. Limit, it is a 12-meter-long bus, a total of six armor, add up to remove the window can not hate more than 100 square meters of surface area, thicker one centimeter will add more than one cubic meter of material, Even if it is a titanium alloy, it has to be four or five tons!
"Add another centimeter." After the team leader pondered it, he still asked: "Half-centimeter liquid bulletproof material, half-cm composite armor, the total weight increase will never exceed five tons, which is much lighter than those big cars. Ok?"
Adding at least one centimeter will add at least 30% of the safety factor. Guo Tailai also understands the idea of ​​the team leader. Guo Tailai thinks more about the performance of the car. The highest speed can run to nearly 200 kilometers per hour. As a result, the team leader shook his head directly, no need, and a speed of up to 150 kilometers per hour was enough. And on the bus, the top can be equipped with pop-up grille armor, and other suitable parts can also be equipped with some remote control machine guns or howitzers for counterattack, which is enough speed.
A bite, nothing can't do, plus! Guo Tailai quickly rushed back to the studio, and spent another day processing a batch of test armor plates, again to the shooting range test.
The combination of these bulletproof materials is not so easy, and Guo Tailai's processing methods have played a big role in it. Support and fit require special craftsmanship. With a gap of one centimeter, Guo Tailai is hard to process a layer of graphene bullet-proof layer with 500 layers. Apart from Guo Tailai, almost no one can do it.
The thickness of the thickened bulletproof board has reached 5.5 cm, which is two centimeters thicker than the 3.5 cm on the red flag. The liquid bulletproof material is thicker and has a thickness of 1.5 cm and 1,500 layers. The double-layered graphene is used as the skeleton. The addition of this kind of non-Newtonian fluid makes the attack of some of the shrapnel that can only be used for homogeneous armor completely useless. The armor material oscillates to break, but these shock waves are absorbed by several layers of liquid ballistic material and do not produce enough fluctuations to break the internal armor.
Of course, no matter what ammunition, after the caliber exceeds a certain value, there is no such thing as bulletproof. The caliber is just right!
When the test was carried out this time, the armor-piercing projectile fired by the 57mm anti-aircraft gun still succeeded in breaking through the bulletproof board, but it was firmly embedded in it and failed to continue to cause lethality.
Seeing this scene, the team leader of the working group was only a smile, and Guo Tailai shook his head.
The next step is to test the RPG attack after adding the grill armor. The grille armor resists the attack principle of RPG. Guo Tailai does not need to explain. With this thing, 50 to 60 of the RPG attacks can be clipped by the grille. Living with loss of attack, the remaining 50% probability of hitting the grille exploding a metal jet will cause the jet to deflect, and the grille armor is at least thirty centimeters from the main armor, and the RPG is best. The height of the shot does not exceed the focus of three to five centimeters. With such a long distance, the power is further reduced.
At the time of the test, at least five RPGs were fired, four of which were caught by the grille, one hitting the grille and the metal jet was centered on the deck. But this time, a 1.5 cm liquid bulletproof layer and a 1,500 layer graphene skeleton played an important role. The tough metal jet only broke the armor plate, but it did not break down, and it was stuck in the bulletproof board.
Everyone was relieved to see this result. When Guo Tailai once again looked at the leader of the working group, the team leader nodded for the first time: "Yes!"
Now that the test has passed, then naturally, it is natural to start making it. The team leader at the beginning thought about estimating the cost of a car, but after seeing the materials and processing techniques of the ballistic panels, they would not do this futile work. It doesn't make sense to count it. Except Guo Tailai, there is no way for other people to make such bulletproof materials. This car is a white one or a few unique cars, just like the big red flag T head.
Guo Tailai did not stop in the first half of the month. In addition to the purchase of goods, Guo Tailai has already built some basic components, and now waits for the final processing of the bulletproof board.
At the end of April, Guo Tailai completely completed the production of three armored buses.
Three black painted armored buses, so quietly squatting in the courtyard of the studio, all the fierce atmosphere converges in the square car, only the T head in the center of the car The mark is shining.
