    So Song Yanan led the team to start the road to improve titanium-aluminum alloys. At the beginning, they had no goals and just moved inertly in the direction of alloys.

    Fortunately, Ascendas Aviation Corporation, as an export-oriented enterprise, attaches great importance to the collection and compilation of foreign technical materials, especially aerospace technology trends and core journals from Europe, the United States, Japan and other countries. As long as nothing unexpected happens, they will be ordered through Hong Kong Island.  , transferred back to China.

    Therefore, although Song Yanan and others had no direction, they had enough references, including several articles briefly introducing metal matrix composite materials, which inspired them a lot.

    A closer look revealed that it is a bit difficult for the Ascendas Aviation Technology R&D Center to take the alloy direction, but it seems easier to try fiber-reinforced metal matrix composites.

    "This would be unbelievable in other materials research institutions. If those who work on materials don't have any metallurgical skills, what kind of materials will they work on?

    But at the Tengfei Aviation Technology R&D Center, which is very partial to science, metallurgy is exactly their weakness. Even the half-dead titanium-aluminum alloy they have is still made at a high price based on Japanese technical data.

    In other words, apart from titanium and aluminum, Ascendas Aviation Technology R&D Center has a very average grasp of other metal materials. If it were to use alloys, it would be like starting from scratch. It would be time-consuming and labor-intensive, and the investment would increase exponentially.

    But when it comes to fiber-reinforced metal matrix composites, the advantages of Ascendas Aviation Technology R&D Center are obvious, because their specialty is carbon fiber composites, and their understanding of various carbon elements and their compounds is not as thorough as usual.  Not to mention, how to condense carbon fiber is a unique task of Ascendas Aviation Technology R&D Center.

    If metal elements can be integrated into carbon fibers to produce better composite materials and improve the properties of titanium-aluminum alloys, will there be broad application prospects?

    Since the general hardware is available at the Ascendas Aviation Technology R&D Center, the only thing missing is the fusion process of carbon fiber and metal elements, so there is nothing to say, just roll up your arms and be done.

    Of course, Song Yanan and the others did not directly use titanium-aluminum alloy this time. Instead, they started with simple aluminum and tried to combine it with the aluminum element using their best t300 carbon fiber to generate aluminum-based composite fiber filaments in order to confirm their theory.

    This confirmation has been confirmed for more than a year. Finally, after breakthroughs in chemical vapor deposition technology and fiber calcination technology, aluminum-based fiber filaments that meet the requirements were made, and then high temperature and high pressure were used to make the side-by-side fiber filaments into carbon fiber reinforced aluminum.  matrix composite materials, after undergoing a series of actual inspections and tests.

    It was discovered that the performance of carbon fiber reinforced aluminum matrix composite materials was not generally good, so he quickly reported it to Zhuang Jianye in a briefing. While introducing the new achievements of the aviation technology research and development center, he suggested that the discovered carbon fiber reinforced aluminum matrix composite materials be applied to  On the main load-bearing structural parts of aircraft or general parts of gas turbine engines.

    Zhuang Jianye was also shocked when he saw this briefing. Others didn¡¯t know about carbon fiber reinforced aluminum matrix composites. Doesn¡¯t he, a person who has lived two lifetimes, not know about it?

    ????????????????????????????????????????????????????????????????

    Because once the technology tree of composite materials is lit up, the technological leap forward for future aerospace will be immeasurable. If nothing else, if the aluminum base is replaced with a carbon base, the resulting carbon fiber reinforced carbon-based composite material will suddenly  It was mentioned to another new level.

    How high is it?

    Decades later, the heat-insulating tiles covered by the U.S. military¡¯s most mysterious X-37B low-Earth orbit vehicle were made of carbon fiber-reinforced carbon-based composite materials.

    It would be even worse if it were replaced with a ceramic base, because it is naturally resistant to high temperatures and high strength, and is an excellent material for the surface of the warhead of supersonic attack weapons.

    As the saying goes, as long as it continues along this path, Ascendas Aviation Corporation will continue to stand still and see that various composite materials made of carbon fiber can move sideways in the aerospace field.

    What else can I say, just throw money in, so 20 million was allocated to the Aviation Technology Research and Development Center without saying a word, specifically for the research of carbon fiber reinforced metal matrix composite materials, 10% of the funds was used as project incentives  Fund, used for rewards and subsidies for scientific research team members.

    10% of 20 million is 2 million. Just after the results came out, and before commercial transformation, they got 2 million. Not to mention the excitement of Song Yanan and others who were originally going for small money. In the past year or so,  The hard work and hard work were all worth it, so while ensuring the progress of carbon fiber composite materials, we quickly started research on titanium-based composite materials and other aluminum-based composite materials.

    And soon completed the silicon carbide fiberThe development work of strong titanium matrix composite materials and silicon carbide fiber aluminum matrix composite materials has been carried out, but unprecedented difficulties have been encountered in carbon fiber reinforced titanium matrix composite materials.

    In this regard, Zhuang Jianye did not urge Song Yanan and the others, because carbon fiber reinforced titanium-based composite materials are a global problem. As the best material for future large bypass ratio turbofan engine fan blades, the British Rolls-Royce Company because of this  Almost bankrupt.

    ? ? American General Motors also almost ran out of money because of this material. It relied on the continuous blood transfusion of the powerful financial system of the United States to survive, and finally completed a breakthrough in this field.

    The fan blades on the GE90 high-bypass turbofan engines equipped on the Boeing 777 and Boeing 787 are made of this material. Compared with traditional titanium alloy materials, the weight is reduced by more than 30%, but the strength is increased.  More than double that after a 1.5kg bird hit it at high speed, the blades were not damaged at all and continued to work normally, showing extremely strong safety.

    Once the performance of the ge90 engine came out, it became another hit after the gf6 engine.

    Even Rolls-Royce and General Motors are excited about carbon fiber-reinforced titanium-based composite materials. Ascendas Airlines, which is not as big as a fingernail, dare not let go and can only guarantee general performance.  I don't dare to bet on my worth.

    In fact, even if Ascendas Airlines wants to take a gamble, it can¡¯t do so because the previous three metal matrix composite materials have almost exhausted Ascendas Airlines¡¯ old foundation. Therefore, Zhuang Jianye seems to be doing nothing during this period.  Yes, in fact, I am thinking about how to make money all day long.

    Whether it is putting forward opinions on financial service support or an attitude of all-out disaster relief, to put it bluntly, these are Zhuang Jianye's means of seeking funds and policies.

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

    Even now, a team of naval experts is being brought to inspect the D-50 gas turbine power plant with a long length of aviation power. The purpose is the same.

    It would be great if the D-50 gas turbine power unit can be marketed. If not, there are so many good materials here. The Navy and the Second Artillery both have long-range missiles, which are considered necessary. Can we provide some funds?  And with policy support, we can¡¯t let Ascendas Aviation Manufacturing Corporation go it alone, right?

    I thought this was a long and arduous process, but I never thought that as soon as I had started, Director Zhao jumped out excitedly and helped me explain the basic situation of carbon fiber reinforced aluminum matrix composite materials, which saved Zhuang Jianye.  There was a lot of talk. As for the effect, you can see it just by looking at Song Changzheng's expression. There was shock in the confusion, and indescribable excitement and excitement hidden in the shock.

    Finally, he stared at Director Zhao and said with a trembling tone: "Old Zhao, are you telling the truth? The second-stage instrument bracket and the entire third stage of the U.S. Trident 2 submarine-launched missile are made of this kind of carbon fiber reinforcement.  Made of aluminum-based composite materials?¡±
