China's Carbon Fiber
Istraživanje industrije karbonskih vlakana u Kini može se pratiti do 1960-ih.
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.
U tom kontekstu, gospodin Shi Changxu, strateški naučnik i akademik Kineske akademije nauka i Kineske akademije nauka, preuzeo je vodeću ulogu u raspravi o industrijalizaciji ugljeničnih vlakana 2000. godine.
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.
Od tada, Kina je službeno ušla u brzu stazu nezavisnog istraživanja i razvoja karbonskih vlakana...
Kako karbonska vlakna postaju popularna u inostranstvu?
Krajem 19. stoljeća, Britanac Joseph Swan i Amerikanac Thomas Edison izumili su karbonsko vlakno u potrazi za poboljšanim nitima sijalica. Iako je ova karbonska nit u to vrijeme zamijenjena jeftinijim volframovim nitima, ovaj karbonizirani vlaknasti materijal se sada smatra najranijim proizvodom karbonskih vlakana.

U kasnijem istorijskom razvoju, ugljenični filament se uvek smatrao neuspehom optimizacije filamenta, i nije dobijao pažnju u industriji i proizvodnji.
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.
U to vrijeme, za vrijeme Hladnog rata između Sovjetskog Saveza i Sjedinjenih Država, razne utrke u naoružanju su uzele maha. Ako imaš avion, ja ću otići u svemir, a ako ti odeš u svemir, ja ću ići na Mjesec. Kao materijal sa odličnim performansama u vazduhoplovstvu i vojnim poljima, karbonska vlakna su takođe u širokoj upotrebi.
Prvi čovjek na Mjesecu: Armstrong
Pošto Sjedinjenim Državama treba, onda je tu Japanska proizvodnja.
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.
Godine 1961. Akio Shinto iz industrijske laboratorije u Osaki uspješno je izumio tehnologiju za pripremu karbonskih vlakana na bazi poliakrilonitrila (PAN)-.

Ranije je prinos karbonizacije NASA-ovih vlakana na bazi viskoze{0}} bio relativno nizak, samo 20 posto. Odnosno, nakon karboniziranja 100 kg vlakana na bazi viskoze-, može se dobiti samo 20 kg karbonskih vlakana.
Prema molekularnoj formuli viskoze, udio atoma ugljika je oko 44 posto, ali u procesu karbonizacije polovina atoma ugljika reagira s kisikom, vodikom i dušikom. Ovo također rezultira nižim performansama karbonskih vlakana-na bazi viskoze, što nije zadovoljavajuće.
Akio Jindo je koristio PAN da bi imao karakteristike termičke stabilnosti nakon pre-oksidacije, odnosno tokom procesa karbonizacije, hemijska aktivnost atoma ugljika u PAN vlaknima nije visoka, a atomi ugljika mogu biti dobri. održavan.
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.
Sa -tehnologijom pripreme iz prve ruke prekursora poliakrilonitrila, Toray je uspješno bio na čelu pripreme karbonskih vlakana.
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.
