1959: Carrying the achievement system, she rolled

"First of all, it must be resistant to high temperatures, have low density, high hardness, and be able to resist physical impact. Only such materials can maintain strength under high-temperature and high-speed impacts to withstand the energy of ammunition." Du Yimeng said. What she didn't mention was that it also had to maintain the advantage of light weight.

After saying this, not only she, but everyone fell into thinking, what kind of material can meet these requirements?

"Ceramics..." Qiao Gong and Du Yimeng said in unison. Ceramic materials are brittle and cannot withstand knocks and collisions, but carbonized ceramics are different.

It not only has the characteristics of super high hardness and high elastic modulus, but is also light in weight. Of course, its price is also amazing.

But no one cares about this issue. The new tank they are researching is a main battle tank. If they insist on considering the cost issue, then they will not be able to continue the research at all.

The domestic technological level is here, and they have already considered many issues. If they continue to save costs, they will not be able to do it at all.

"Xiao Du, come with me to the office." Engineer Qiao said to Du Yimeng, and then glanced at Qin Chulong who was standing between him and Du Yimeng. He felt that it didn't matter if there was a middleman because he was blocking his way.

Qin Chulong didn't say a word, but turned and left. His whole heart was on the engine, so he had no time to stay here.

After Du Yimeng followed Engineer Qiao to the office, the two began to discuss whether ceramics could effectively reduce the instability and yaw of ammunition.

First of all, we have to overcome the limitations of ceramic materials. In addition to being brittle, ceramics also have thickness effects and angle effects, which are all difficult problems.

The idea is good, but that doesn't mean it will necessarily have the effect they want.

Perhaps the thicker the ceramic, the lower the protection factor may be. These are all issues to consider.

Ceramics have high hardness, but their toughness is also very poor. Even if they are made into ceramic armor, they are very easy to break.

"Can we use the unique physical properties of ceramics to make it have a rebound effect?" Du Yimeng asked. After all, they wanted it to offset the energy of ammunition and play a protective role.

"What do you mean?" Upon hearing this, Qiao Gong frowned more and more, but he did not stop her. Instead, he let her continue.

"If the ceramics are re-fired into spheres and then the small spheres are bound together, it may have the effect of rebounding," said Du Yimeng.

To put it simply, the protective armor they are making now is equivalent to a target, and the ammunition attacking them is equivalent to the bullets of a gun.

Is it easier for a bullet to hit a target if it hits a flat surface or a spherical shape?

Of course it’s the former!

"But in this case, the back plate of the ceramic armor must be made of a metal with high toughness and strength." Du Yimeng couldn't help but frowned when he said this.

Without such metals, armor made of ceramics could become weapons that kill themselves once attacked.

It seems like a joke that the protective armor you make yourself turns into a weapon to kill yourself, but in today's technologically backward era, it may really happen.

Engineer Qiao frowned even more deeply. He was wondering whether this protective armor could really achieve the protective effect they wanted.

If what Du Yimeng said is true, then the alloy steel they had worked so hard to develop might be unusable.

Re-studying the materials would take a lot of time, but what he was most worried about was another outcome: failure again.

You have to know that they are also racing against time, even though the higher-ups have not given them a specific timeline. However, the higher-ups attach great importance to the new tanks, and people come to inspect them from time to time.

"I think we can give it a try." When Qiao Gong said this, his eyes were full of determination. It was just a new type of alloy steel, which was his strong point, so he was not afraid!

If what she said is true, the strength and hardness of this composite armor are higher than those of a single material, and it also has greater impact resistance.

It can also reduce its own weight, and most importantly, it is fire-resistant and high-temperature resistant. With so many advantages, why don’t they give it a try?

When he thought about being able to create the best protective armor, he felt his fatigue dissipate a little.

He felt that as long as he could wash his face, he could go back to the laboratory and stay up for two more nights.

No one expected that the origin of composite armor steel was because it was impossible to make armor steel with better protection capabilities.

Later, when someone asked Mr. Qiao where his inspiration for making composite armor steel came from, he quickly turned the topic to Du Yimeng.

He is just a worker, and she is the chief designer.

The reality is that he couldn't answer it. He could only say that he couldn't make armored steel with better protection. That's why he listened to Du Yimeng's suggestion with a try-it attitude!

……

When Du Yimeng walked out of the laboratory, it was already dark. She remembered that she was called away after lunch and couldn't help but sigh that time passed so quickly!

She moved her stiff shoulders. It turned out that using the brain was also a physical activity. Then she felt her chest swelling.

She subconsciously put her hand on her chest, and suddenly her eyes widened and she reacted.

Oh my god, her Fang Bao!

She reacted quickly and ran to Yu Lang's office. She ran very fast, which showed that all those years of morning exercises were not in vain.

It's been half a day, her Fang Bao must be starving, right?

When I ran there, I saw an incredible scene. Captain Hao was sitting on a chair holding Fang Bao and chatting with Fang Bao in a clip voice.

Fang Bao responded with "ah and oh", and the two of them seemed to be having a great chat!

Every time her little mouth opened and closed, saliva would flow down uncontrollably. Captain Hao didn't mind and wiped it carefully with a handkerchief.

He looked so cautious, as if he was treating a porcelain doll.

When Captain Hao saw that the person coming was Du Yimeng, his expression stiffened a little, and then returned to normal.

He had just heard the chaotic footsteps and guessed that it was Du Yimeng, the incompetent mother, who had come running. She finally remembered her daughter Fang Bao.

He wanted to hide his clapping voice, but Fang Bao was so cute that no matter what he said, she responded with "ah or oh".

Even though her parents were unreliable, she actually smiled at him. She was so silly and cute!

Especially those big, wet eyes, which were filled with his reflection, melted his heart.

He simply stopped pretending, and to hell with his personality!

He used to think that being single would allow him to better serve his country, but now he feels that getting married early doesn't seem to be a big deal.

"Where is Yu Lang?" Du Yi dreamed that Yu Lang was not in the office and asked subconsciously.

"There's something going on in the Security Department that needs him to go over and take care of it. He just left not long ago." Captain Hao said. Yu Lang asked him to go over and take care of it, but he refused to go.
