So Song Yanan led the team to start the road of improving titanium aluminum alloy, and at first they didn't have any goal, but just went down by inertia in the direction of the alloy.

Fortunately, as an export-oriented enterprise, Tengfei Aviation Corporation attaches great importance to the collection and sorting of foreign technical data, especially the technical trends and core journals of Europe, America, Japan and other countries.

Therefore, although Song Yanan and others have no direction, they have enough references, and several articles briefly introducing metal matrix composites have given them great inspiration.

After a closer study, it is found that it is somewhat difficult for the Tengfei Aviation Technology R&D Center to take the direction of alloys, but it seems to be easier to try fiber-reinforced metal matrix composites.

This would be incredible in other materials research institutions, and if you don't have some metallurgical skills, you will still be engaged in any materials.

But in the serious Tengfei Aviation Technology R&D Center, metallurgy is precisely their weakness, even if the half-dead titanium aluminum alloy in their hands is still based on Japan's technical data, and it costs a lot of money to get it.

In other words, in addition to titanium and aluminum, the Ascendas Aviation Technology R&D Center has a very general grasp of other metal materials, which is tantamount to starting from scratch if it is alloyed, not to mention time-consuming and labor-intensive, and the investment will be multiplied.

But if you take the fiber-reinforced metal matrix composite, the advantage of Tengfei Aviation Technology R&D Center is obvious, because their old business is carbon fiber composite materials, and various carbon elements and their compounds are not generally thorough, not to mention, how to condense carbon fiber is Tengfei Aviation Technology R&D Center's unique work.

If metal elements can be integrated into carbon fiber to generate more excellent composite materials and improve the characteristics of titanium and aluminum alloys, will there be broad application prospects?

Since the general hardware is available in the Tengfei Aviation Technology R&D Center, the only thing that is poor is the fusion process of carbon fiber and metal elements, so there is nothing to say, just do it with your arms.

Of course, this time Song Yanan did not directly apply titanium and aluminum alloys, but started with simple aluminum, and tried to combine with aluminum elements with the best T300 carbon fiber to generate aluminum matrix composite fiber filaments, so as to confirm the theory they proposed.

This confirmation has been confirmed for more than a year, and finally after breaking through the chemical vapor deposition technology and fiber calcination technology, the aluminum-based fiber filament that meets the requirements has been made, and then the side-by-side superimposed filaments are made into carbon fiber reinforced aluminum matrix composite materials by using high temperature and high pressure, and after a series of practical tests and tests.

It was found that the performance of carbon fiber reinforced aluminum matrix composites was not generally good, so he hurriedly reported to Zhuang Jianye with a briefing situation, and at the same time introduced the new achievements of the aviation technology research and development center, it was suggested that the carbon fiber reinforced aluminum matrix composites should be applied to the main load-bearing structural parts of aircraft or the general parts of gas turbine engines.

Zhuang Jianye, who saw this briefing, was also surprised, others don't know about carbon fiber reinforced aluminum matrix composites, doesn't he, a person who has lived two lifetimes, not know?

I really didn't expect the Aviation Technology R&D Center to make such a big battle, and I was surprised and uncontrollable excited.

Because once the technology tree of this composite material is lit, the technological leap of the future aerospace is immeasurable, not to mention anything else, if the aluminum base is replaced with a carbon base, the resulting carbon fiber reinforced carbon matrix composite material will suddenly reach another new height.

How tall?

Decades later, the most mysterious X-37B low-earth orbiter of the U.S. military covered with thermal insulation tiles was made of carbon fiber-reinforced carbon matrix composite materials.

It is even more difficult if it is replaced with a ceramic base, because the natural high temperature resistance and high strength are excellent materials for the surface of the warhead of hypersonic attack weapons.

As the so-called all-in-one, as long as you go down this road, Tengfei Aviation Corporation will be able to walk sideways in the aerospace field even if it stands still in the future, looking at various composite materials made of carbon fiber.

What else is this, just throw money into it, so 20 million two without saying a word was allocated to the Aviation Technology Research and Development Center, specifically for the research of carbon fiber reinforced metal matrix composite materials, of which 10 of the funds are used as project incentive funds for rewards and subsidies for scientific research team personnel.

10 million of 20 million is 2 million, just out of the results, before the commercial transformation to get 2 million, Song Yanan and others who were already rushing to a small amount of money to not mention the excitement, the past year has been hard and tired feel that it is worth it, so while ensuring the progress of carbon fiber composite materials, quickly began the research of titanium matrix composites and other aluminum matrix composites.

The development of silicon carbide fiber reinforced titanium matrix composites and silicon carbide fiber aluminum matrix composites was quickly completed, but it encountered unprecedented difficulties in carbon fiber reinforced titanium matrix composites.

In this regard, Zhuang Jianye did not urge Song Yanan to them, because carbon fiber reinforced titanium matrix composite materials are a worldwide problem, as the best material for the fan blades of large bypass ratio turbofan engines in the future, the British Rolls-Royce company almost went bankrupt because of this.

General Motors of the United States was also almost exhausted because of this material, and it survived by continuous blood transfusions of the powerful financial system of the United States, and finally completed a breakthrough in this field.

Compared with the traditional titanium alloy material, the weight is reduced by more than 30, but the strength is more than doubled, so that after the high-speed impact of the 15-kilogram flying bird, the blade is not damaged at all, and continues to work normally, showing strong safety.

As soon as the performance of the GE90 engine came out, it became another popular model after the GF6 engine.

Even Rolls-Royce and GM are eager to die because of the carbon fiber reinforced titanium matrix composite materials, and the Tengfei Aviation Corporation, which is not as big as a fingernail, is even more afraid to let go, and can only ensure general investment, and dare not gamble at all.

In fact, I can't gamble if I want Tengfei Aviation Corporation, because the previous three metal matrix composites have almost exhausted the old foundation of Tengfei Aviation Corporation, so Zhuang Jianye looks like a nobody during this time, in fact, he thinks about how to make money all day long.

Whether it is the opinion of financial service support, or the attitude of disaster relief, to put it bluntly, it is Zhuang Jianye's means to seek funds and policies.

Needless to say, financial services are directly linked to funds; disaster relief looks like a loss, but the policies given by the superiors are indeed better than the other, as long as they are used well, these policies can be quickly transformed into substantial assistance and reduce the cost of enterprises.

Even now the purpose of the D-50 gas turbine power unit with the naval expert group to inspect the long power plant of Tengfei Aviation is this.

If the D-50 gas turbine power unit can be marketed, it is naturally good, if not, so many good materials are placed here, the navy and the second artillery have long-range missiles, which is a proper just need, is it to give some financial and policy support, and we can't let Tengfei Aviation Manufacturing Corporation go it alone, right?

I thought it was a very long and arduous process, but I never thought that I had just started, Director Zhao jumped out excitedly and helped him explain the basic situation of carbon fiber reinforced aluminum matrix composites, which saved Zhuang Jianye a lot of tongues, as for the effect, just look at Song Changzheng's expression, with shock in the dazedness, and indescribable excitement and excitement hidden in the shock.

Finally, he stared at Director Zhao and said in a trembling tone, "Old Zhao, what you said is true? The entire stage of the second-stage instrument bracket and the third-stage of the American Trident 2 submarine-launched missile are made of this carbon fiber reinforced aluminum matrix composite material?"
