China's Carbon Fiber
Kev tshawb fawb txog kev lag luam carbon fiber hauv Suav teb tuaj yeem taug qab mus rau xyoo 1960.
However, until 2000, the industrialization of carbon fiber has not been realized, and due to the long-term development of carbon fiber preparation technology in China, various research units gradually began to have insufficient confidence. RD personnel from all walks of life have avoided the word "carbon fiber". At this time, it is the most difficult trough period for the localization and research and development of carbon fiber materials.
Tawm tsam keeb kwm yav dhau los no, Mr. Shi Changxu, tus kws tshawb fawb txog tswv yim thiab kev kawm ntawm Suav Academy ntawm Kev Tshawb Fawb thiab Suav Academy ntawm Kev Tshawb Fawb, tau ua tus thawj coj hauv kev sib tham txog kev lag luam ntawm carbon fiber hauv xyoo 2000.
At the beginning of 2001, the teacher sent a "request report on accelerating the development of high-performance carbon fiber" to the Party Central Committee. In October 2001, the Ministry of Science and Technology of the People's Republic of China decided to set up a special project on carbon fiber key technologies, code-named 304 special project.
Txij thaum ntawd los, Tuam Tshoj tau nkag mus rau txoj kab nrawm ntawm kev tshawb fawb ywj pheej thiab kev txhim kho ntawm carbon fiber ...
Yuav ua li cas carbon fiber tau nrov nyob txawv teb chaws?
Thaum kawg ntawm lub xyoo pua 19th, British Joseph Swan thiab American Thomas Edison tau tsim cov pa roj carbon filament hauv kev tshawb nrhiav cov teeb pom kev zoo dua qub. Txawm hais tias cov pa roj carbon filament no tau hloov los ntawm pheej yig dua tungsten filaments thaum lub sijhawm, cov khoom siv carbonized fiber ntau tam sim no suav tias yog cov khoom lag luam ntxov tshaj plaws ntawm carbon fiber.

Hauv kev txhim kho keeb kwm yav dhau los, cov pa roj carbon filament yeej ib txwm suav tias yog qhov ua tsis tiav ntawm filament optimization, thiab tsis tau txais kev saib xyuas hauv kev lag luam thiab kev tsim khoom.
Until that magical organization, NASA, appeared on the stage of history, this new type of aerospace material with high temperature resistance, corrosion resistance, high strength and low density was reconnected to modern civilization and was named "carbon fiber".
Just as diapers, air-cushioned shoes, and dehydrated vegetables have all moved from NASA to the civilian field, carbon fiber, as the "new love" found by NASA in the material industry, is naturally valued by various companies to see if it can be the first. A person who eats crabs is the first to seize the market and make a fortune.
As a result, the United Carbon Compound Company UCC entered the carbon fiber development industry, and in 1959 developed the world's first listed viscose-based carbon fiber material Thornel-25.
Lub sijhawm ntawd, thaum Tsov Rog Txias ntawm Soviet Union thiab Tebchaws Meskas, ntau yam riam phom sib tw tau tawm. Yog koj muaj dav hlau mas kuv yuav mus rau lub qab ntuj khwb, thiab yog koj mus rau lub qab ntuj khwb, kuv yuav mus rau lub hli. Raws li cov khoom siv nrog kev ua tau zoo hauv aerospace thiab tub rog teb, carbon fiber kuj tau siv dav.
Thawj tus txiv neej ntawm lub hli: Armstrong
Txij li thaum Tebchaws Meskas xav tau, ces muaj Nyiv ua.
At that time, Japan, as the largest "trophy" of the United States in World War II, also began active research on carbon fiber.
In fact, UCC's Thornel-25 is actually not perfect. The technological name of carbon fiber was synonymous with banknotes in the 1950s. According to the price of gold at that time, carbon fiber of the same quality was more expensive than gold. The high cost of proper black gold became the biggest pain point of carbon fiber at that time.
Xyoo 1961, Akio Shinto ntawm Osaka Industrial Laboratory tau ua tiav cov thev naus laus zis los npaj polyacrylonitrile (PAN)-raws li carbon fibers.
Shinto Akio
Yav dhau los, carbonization yield ntawm viscose-raws li fibers ntawm NASA kuj tsawg, tsuas yog 20 feem pua. Ntawd yog, tom qab 100 kg ntawm viscose-raws li fiber ntau yog carbonized, tsuas yog 20 kg ntawm carbon fiber yuav tau.
Raws li cov qauv molecular ntawm viscose, qhov feem ntawm carbon atoms yog kwv yees li 44 feem pua, tab sis nyob rau hauv tus txheej txheem ntawm carbonization, ib nrab ntawm cov pa roj carbon atoms reacts nrog oxygen, hydrogen thiab nitrogen. Qhov no kuj ua rau kev ua haujlwm qis dua ntawm viscose-raws li carbon fiber, uas tsis txaus siab.
Akio Jindo siv PAN kom muaj cov yam ntxwv ntawm thermal stability tom qab ua ntej -oxidation, uas yog hais tias, thaum lub sij hawm carbonization txheej txheem, cov tshuaj lom neeg kev ua si ntawm carbon atoms ntawm PAN fibers tsis siab, thiab cov pa roj carbon atoms yuav ua tau zoo. khaws cia.
Facts have proved that Kondo Akio's judgment is correct. The carbonization yield of the process route he developed is between 50-60 percent , and the performance is far superior to viscose-based fibers. The conversion rate has risen, and the price has naturally fallen. Since then, PAN has quickly replaced viscose-based carbon fibers. Now the share of viscose-based carbon fibers is less than 10 percent , while PAN-based carbon fibers account for more than 80 percent of the share.
Nrog thawj - tes npaj technology ntawm polyacrylonitrile precursor, Toray tau ua tiav nyob rau hauv pem hauv ntej ntawm carbon fiber npaj.
Subsequently, in 1971, Japan's Toray Company (Toray, English name 'Toray Industries, Inc) cooperated with United Carbon Compounds of the United States to produce T300 carbon fiber, and achieved mass production of 1 ton/month at that time.
Subsequently, Toray Company continued to upgrade the quality of carbon fiber along the T300, T800, T1000, and pioneered the addition of carbon fiber materials to sporting goods such as rackets, fishing rods, golf clubs, etc., which became a sought-after product in the sporting goods industry. Japan's Toray also rose to fame, becoming the world's largest manufacturer of carbon fiber materials.
