"Black Gold" Carbon Fiber: New Material Wang Guo Yao'S Eye Star
Recently, a number of military and technological powers have focused their attention on the "carbon fiber industry development" and other related fields. They are competing to launch the plan to accelerate the development of renewable carbon fiber materials and to set up innovative research institutions. They want to focus on promoting the rapid development of the 6 key technical fields, such as engineering nano technology and carbon fiber, and so on.
Scientific exploration of "black gold" carbon fiber
The origin of carbon fiber dates back to 1860. It was invented and patented by British Cerf Swan in making electric filament.
It is a fibrous carbon material. It is black and hard. It is a new material with higher strength than steel, smaller density than aluminum, corrosion resistance than stainless steel, high temperature resistance than heat resistant steel, and electrical conductivity, thermal and mechanical properties, and so on. Because of its difficult manufacturing technology and high practical value, it is known as "black gold" by the industry.
Carbon fiber "outer soft inside rigid", not only has the essential characteristics of carbon materials, but also has the softness and workability of textile fibers, it is a new generation of high performance reinforced fibers.
The carbon fiber, which is several times thinner than the hair, can be obtained through special compound molding technology. The carbon fiber composite material with excellent performance can be widely used in many fields such as aviation, aerospace, energy, pportation, military equipment and so on. It is an important material for national defense industry and civilian production and life.
Hard to make
Technology
Complex and meticulous
In 1950s, in order to solve the key technical problems such as high temperature and corrosion resistance of missile nozzle and warhead, the United States pioneered the development of viscose based carbon fiber.
In 1959, polyacrylonitrile based carbon fiber was invented by Kondo Akio, Japan.
Because of the outstanding performance of carbon fiber in the military field, it has attracted the attention of the military power.
Subsequently, some countries invested heavily in developing more high-performance and more variety of carbon fibers.
Japan has broken through a series of key technical problems such as high strength, high modulus and so on, making the developed carbon fiber composite material excellent.
Fatigue resistance
The overall level of environmental adaptability is ahead of schedule.
Carbon fiber appears to be simple, but its manufacturing process is very complex. It is a systematic project integrating multi-disciplinary, sophisticated and sophisticated technology, involving chemical industry, textile, materials,
Precision machinery
In many disciplines, the whole process includes high precision control over thousands of parameters such as temperature, humidity, concentration, viscosity and flow rate. A little carelessness will seriously affect the performance and quality stability of carbon fiber, so it is far from the common technology.
With the wide application of carbon fiber and composite materials, large-scale production has become a major bottleneck in its industrialization.
Although the production of each grade is the same, the difficulty of precise control of various process parameters is very different. The production line of ten ton and 100 ton can not be simply copied to 1000 tons. For example, polymerization produces a lot of heat, which makes it difficult to control the uniformity of temperature uniformity.
Because of this, only a handful of countries can produce high-performance carbon fiber at present, and the core technology is mainly in the hands of Japanese and American giants.
Among them, Japan's three companies accounted for 3/4 of the world's carbon fiber production capacity, becoming the industry's "Big Mac".
Strong and strong national defense equipment reborn
According to foreign media reports, one of the most important reasons for the first flight time of F-35 fighters is overweight.
In order to solve this problem, Lockheed Martin has taken many measures, and ultimately the use of up to 35% of carbon fiber composite material to greatly reduce the body weight.
So in a sense, CFRP has made F-35 fighter.
Nowadays, carbon fiber reinforced polymer (CFRP) is not only an indispensable basic material for achieving high stealth performance, but also an important symbol for measuring advanced performance of weapon system.
For example, X-47B, Global Hawk, global observers, westerly wind and other aircraft have higher proportion of carbon fiber composite materials, making their payload, endurance and viability have achieved a new breakthrough.
One of the most important features of active F-22 fighter is the good stealth performance, which is closely related to its use of carbon fiber composites.
In addition, F-117A fighters, B-2 stealth bombers and so on also use carbon fiber absorbing materials, including the Swedish "Weiss ratio" class patrol ships are all composite materials, and therefore have advanced stealth, high mobility, long life and other advanced operational performance.
The development of aerospace is even more important.
If the quality of solid rocket motor is reduced by 1 kilograms, the range can be increased by 16 kilometers.
Therefore, carbon fiber composite materials have been widely used in the "American Patriot" missile, "Trident" II, the German HVM supersonic missile, the French "Ariane" -2 rocket, the Japanese M-5 rocket and other engine shells, and the future carbon fiber is also an important foundation for developing advanced strategic weaponry with miniaturization, high mobility, high precision and high penetration capability.
The new high-performance carbon fiber composite has better stability and reliability. It is widely used in hypersonic vehicles, international space station, advanced satellites and other equipment systems.
The US defense department stressed in the "material research for defense demand in twenty-first Century" report that "by 2020, only composite materials will have the potential to equip 20-25% performance."
