China's Carbon Fiber
Rechèch sou endistri fib kabòn nan Lachin ka remonte nan ane 1960 yo.
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.
Kont sa a background, Mesye Shi Changxu, yon syantis estratejik ak akademisyen nan Akademi Syans Chinwa a ak Akademi Syans Chinwa a, te pran plon nan diskite sou endistriyalizasyon nan fib kabòn nan lane 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.
Depi lè sa a, Lachin te ofisyèlman antre nan liy rapid rechèch endepandan ak devlopman fib kabòn...
Ki jan fib kabòn vin popilè aletranje?
Nan fen 19yèm syèk la, Britanik Joseph Swan ak Ameriken Thomas Edison envante filaman kabòn pou chèche amelyore filaman anpoul. Malgre ke filaman kabòn sa a te ranplase pa filaman tengstèn pi bon mache nan moman sa a, se materyèl fib carbonized sa a kounye a konsidere kòm pwodwi a pi bonè nan fib kabòn.

Nan devlopman istorik ki vin apre, filaman kabòn te toujou konsidere kòm yon echèk nan optimize filaman, epi li pa te resevwa atansyon nan endistri ak pwodiksyon.
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.
Nan epòk sa a, pandan Lagè Fwad ant Inyon Sovyetik ak Etazini, divès kalite kous zam te pran. Si ou gen yon avyon, mwen pral ale nan linivè a, epi si ou ale nan linivè a, mwen pral ale nan lalin nan. Kòm yon materyèl ki gen pèfòmans ekselan nan domèn ayewospasyal ak militè, fib kabòn tou te lajman itilize.
Premye moun sou lalin lan: Armstrong
Depi Etazini bezwen, lè sa a gen Japon te fè.
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.
An 1961, Akio Shinto nan Laboratwa Endistriyèl Osaka te envante avèk siksè teknoloji pou prepare fib kabòn ki baze sou polyacrylonitrile (PAN)-.
Shinto Akio
Anvan sa, rannman karbonizasyon nan viskoz-fib NASA yo te relativman ba, sèlman 20 pousan. Sa vle di, apre yo fin carbonize 100 kg fib viskoz-, sèlman 20 kg fib kabòn ka jwenn.
Dapre fòmil molekilè viskoz la, pwopòsyon atòm kabòn se apeprè 44 pousan, men nan pwosesis karbonizasyon, mwatye atòm kabòn yo reyaji avèk oksijèn, idwojèn ak nitwojèn. Sa a tou rezilta nan pèfòmans ki pi ba nan fib kabòn ki baze sou viskoz-, ki pa satisfezan.
Akio Jindo te itilize PAN pou gen karakteristik estabilite tèmik apre pre-oksidasyon, sa vle di pandan pwosesis karbonizasyon, aktivite chimik atòm kabòn fib PAN pa wo, ak atòm kabòn yo ka byen. kenbe.
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.
Avèk premye -teknoloji preparasyon men nan polyacrylonitrile précurseur, Toray te avèk siksè nan forefront nan preparasyon fib kabòn.
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.
