The fishing guy never thought that he would accidentally help the development of ancestral workers!
In the fishing industry, there is a well-known industry saying, fishing guys will never be in the air force.
The so-called "air force" refers to the situation where you don't catch a single fish and go home empty-handed, that is, you can't catch anything by laughing at your fishing skills.
However, it is estimated that many people do not know that there is another meaning in this sentence, the fishing guys are competing with the Air Force for key strategic resources.
This is not a groundless thing, the key is in the fishing rod.
Fishing rod with carbon fiber
Anyone who has ever fished knows that fishing is a high-tech thing.
Especially after the fish bites, the man and the fish will compete for a period of time, and the strength and toughness of the rod are particularly important.
If it is a rod with poor strength and toughness, the rod will break as soon as the big fish is strenuous and the rod will break.
And a good fishing rod is different, especially a fishing rod made of carbon fiber, which is much more powerful.
Not only can you catch hundreds of pounds of big fish, but you can even bend into a circle, oh yes, there is a word called rather bend than bend!
In order to meet the various needs of anglers to the greatest extent, the enterprises that produce fishing rods are also chasing me, and Fei Lao has a hard nose.
For example, there is a fishing tackle company called Guangwei in Shandong, which has invested heavily in research and technology to gnaw, which not only requires high strength limits, but also pursues the ultimate in lightweight.
Later, I don't know if any engineer is outstanding, but I really got it out anyway.
This is a great event, so much so that it is rumored that a certain military leader was amazed by its results after visiting the enterprise, and this thing is good!Brother, stop making fishing rods, let's do military industry.
Guangwei did not fail in its mission, and it did not take long to create a military-grade carbon fiber composite material, breaking the long-term monopoly of foreign countries in this regard.
For example, the J-20 fighter jet, its fuselage, main wing, vertical tail, flat tail and skin, a large number of carbon fiber composite materials are used, and the use rate has reached about 20%.
It uses pure domestic T700 grade carbon fiber, which is ahead of the T300 material technology level of the American F-22.
T stands for high-strength type, and the higher the number after it, the better the strength.
The data shows that the J-20 front fuselage section with composite material structure can reduce the weight by 31 compared with the metal structure5%, 61 fewer parts5% to reduce fasteners by 613%；Composite vertical stabilizers reduce mass3224%。
See, these numbers are quite scary.
There are also civil aspects, such as the domestic C919 large aircraft, 15% of the fuselage uses resin-based carbon fiber composite materials, which is the first time that a large civil passenger aircraft has used this material in a large area.
It is said that the strength of the material has reached the T800 level, which is too many benefits compared to traditional materials.
For example, under the premise of the same strength, it can be 80% lighter than ordinary traditional materials;
Its fatigue life is also longer, the service life of general metallic silver materials is 20 years or 60,000 flight hours, while it can reach 30 years or 90,000 flight hours, and the structural life can be increased by 50%.
The fishermen never thought that their own needs indirectly helped the military industry solve a big favor!
However, the boss of Guangwei put on a aggrieved face, "On carbon fiber, in essence, we want to solve the problem of fishing rods at the earliest, and we don't know whether the country needs it, we know the demand for fishing rods."
I have to say, this boss is really cute.
Despite this, those netizens who don't think it's a big deal to watch the excitement still found clues on Guangwei's official website.
For example, in its industry profile, there is such a paragraph: "Carbon fiber as the main body of the expansion fiber plate." Guangwei precision machinery plate with precision machinery and aerospace capsule as the main body".
Obediently, it can't be more straightforward if it's already straightforward, everyone who understands it understands it.
Carbon fiber history
So, what is the power of carbon fiber?
Carbon fiber is a very advanced material, also known as the "king of materials", which is seven to nine times stronger than ordinary steel, but only a quarter of the weight.
In addition, high temperature resistance and low temperature resistance are also its advantages, up to 3000, down to minus 180 can be carried, but also has oil resistance, acid resistance, corrosion resistance and other high-quality performance.
Let's put it this way, installing this thing on an airplane not only reduces weight, but also allows it to withstand more loads and stresses.
Less weight means lower fuel consumption and higher efficiency, and for airline bosses, of course, it's a grin.
However, carbon fiber is good, but how to produce it in large quantities has become a headache in front of us.
For example, setting up a carbon fiber production line requires a lot of investment, high equipment costs, complex production processes, and construction and commissioning cycles of up to several years.
The equipment alone will cost at least $25 million and could take up to two years to be operational.
For a long time in the past, the United States and Japan were two countries in the absolute monopoly in the field of carbon fiber.
China wants?Yes!Buy with a large amount of American knives, and even so, they say that the price will increase, and the supply will be cut off, that is, "notice price increase, reward supply".
There's no way, it's just bullying us and we can't produce it.
Around 2000, China began to make breakthroughs, and China's famous metallurgical and materials scientist Shi Changxu took the lead in proposing to the country that carbon fiber must be overcome.
The military industry department once thought that it would take great efforts to develop independently, but you said that it was a coincidence or not, Guangwei, which produces fishing rods for anglers, is also being developed.
In 2005, the domestic carbon fiber developed by Guangwei passed the national acceptance, breaking the foreign blockade in one fell swoop.
Later, Guangwei made a breakthrough in a number of models of carbon fiber, and has broken through the key technology of the third generation of carbon fiber represented by high-strength T1100 and high-strength, high-modulus and high-extension M40X, leading the country in China.
Nowadays, the whole industrial chain of carbon fiber and its composite material production and research and development can be completed by Guangwei alone.
Their products have been successfully applied to China's commercial aviation C919, amphibious aircraft Jiaolong AG600, launch vehicles, satellites and other major heavy weapons.
In terms of production capacity, in 2012, China's carbon fiber production capacity was 120,000 tons;And in 2017, that number rose to 260,000, making it the third after the United States and Japan.
In 2022, we have an internationally leading 10,000-ton production line, and our production capacity has soared to 1120,000 tons;
A comparable data is that the United States, as the world's second largest carbon fiber production capacity, will have a carbon fiber production capacity of 47,900 tons in 2022.
Therefore, it is said that it is far ahead in the world, and there is nothing wrong with it.
Look, it's all right!Sometimes it's not someone else who gets stuck in our neck, it's that we wear the sweater backwards.
Ending
Good guys, since the emergence of the giant blockade, this has triggered a big industrial investigation, and a lot of hidden kings have been found.
I don't know if I don't touch it, I develop it in seconds!
No wonder the fishing guy is in the Air Force every time, it turns out that it is really the Air Force.
Well, if we are poor, we will concentrate on doing great things, and if we are rich, we will concentrate on finding out the bottom of it!
Hell, how many dragon slaying black technologies do they have!
