By 2025, my country's new materials will achieve 10 trillion, and these three directions will definitely explode
Ib qho ntawm cov khoom siv tshiab: cov khoom siv hnyav
1. Carbon fiber ntau
Carbon fiber materials are used in aerospace, wind power, sports and leisure, automobiles and other fields with their excellent properties. They are the most widely used and market-oriented materials in the field of new materials, and are known as "the king of new materials". The global carbon fiber market demand has grown rapidly in recent years, and my country has also seized the opportunity to develop into the world's second largest carbon fiber producer.
However, compared with foreign countries, my country's carbon fiber industry still has the problems of low capacity utilization, few high-end products, and difficult application and development. The downstream industry still relies heavily on imported carbon fiber products. In the current international environment, realizing the dual autonomy of carbon fiber scale production and application development is the key to enhancing my country's national defense and manufacturing strength and ensuring the stability of the supply chain.
Carbon fiber is a carbon backbone structure inorganic fiber with a carbon content higher than 90 percent formed by the pyrolysis and carbonization of organic fibers such as polyacrylonitrile (PAN) (or pitch, viscose) in a high temperature environment, as a high-performance material. Produced in the 1960s.
Cov pa roj carbon fiber ntau muaj cov khoom siv zoo heev thiab tshuaj lom neeg ruaj khov: raws li cov fiber ntau uas muaj lub zog tshwj xeeb tshaj plaws (lub zog tshwj xeeb ntom) thiab qhov siab tshaj qhov nruj (modulus tshwj xeeb ntom) ntawm cov siab -kev ua haujlwm fibers uas tam sim no loj{{1 }}tsim, carbon fiber yog ib feem tseem ceeb ntawm aerospace, cua zog Cov ntaub ntawv zoo tshaj plaws rau cov hniav, lub zog tshiab tsheb thiab lwm yam kev lag luam nrog lub teeb yuag. Cov yam ntxwv ntawm corrosion kuj, kub tsis kam thiab me me expansion coefficient ua rau nws hloov rau cov ntaub ntawv hlau nyob rau hauv ib puag ncig hnyav; Tsis tas li ntawd, cov khoom siv hluav taws xob thiab thermal conductivity nthuav dav nws daim ntawv thov hauv kev sib txuas lus electronics.
Raws li tus naj npawb ntawm filaments nyob rau hauv txhua pob ntawm carbon fibers, carbon fibers feem ntau muab faib ua ob pawg: me me cab thiab loj cab. Cov cab me me muaj kev ua tau zoo dua tab sis tus nqi siab dua, thiab feem ntau yog siv hauv high -tech fields xws li aerospace thiab tub rog kev lag luam, nrog rau siab - khoom ntaus pob ncaws pob kawg; cov cab loj muaj tus nqi qis dua thiab feem ntau siv rau hauv kev lag luam yooj yim, suav nrog kev tsim kho pej xeem, kev thauj mus los thiab cov khoom siv hluav taws xob, thiab lwm yam.
Ntiaj teb no Peev xwm Scale thiab xav tau kev cia siab
In 2020, the global carbon fiber operating capacity is 171,650 tons, an increase of 16,750 tons compared with 2019, a growth rate of 10.8 percent . The United States, China, and Japan assumed the main production capacity, accounting for 21.7 percent , 21.1 percent , and 17.0 percent , respectively. At present, the major manufacturers still have about 80,000 tons/year of unfinished expansion plans, which also reflects the manufacturers' optimistic expectations for the industry's prospects.
Nyob rau hauv cov nqe lus ntawm kev thov, plaub daim ntawv thov loj industries ntawm lub lag luam carbon fiber yog aerospace, cua zog hniav, kev ua si thiab leisure, thiab tsheb. Xyoo 2020, plaub qhov kev lag luam qis qis yuav suav txog ntau dua 70 feem pua ntawm cov pa roj carbon fiber ntau thiab ntau dua 76 feem pua ntawm cov nqi tso tawm.
Since 2015, the industry estimates that the world's carbon fiber demand has maintained a growth of about 12 percent , but due to the impact of the epidemic, the global demand for carbon fiber in 2020 will total 107,000 tons, an increase of only 3 percent compared to 2019. The total sales amount was about 2.615 billion US dollars, a year-on-year decrease of 8.8 percent , mainly due to the slump in the aviation industry caused by the epidemic, which affected the sales of high-value high-performance carbon fiber. The wind power field has become the main driving force for the industry to maintain growth, and the demand for carbon fiber has maintained an annual growth of 20 percent despite the epidemic.
In the short term, the recovery of the world aviation industry and the large-scale laying of wind power equipment in 2021 can bring the carbon fiber market back to the channel of rapid growth. In the long run, the aviation industry needs to digest the excess capacity in 2020, and wind power will continue to be the main driving force for the growth of the carbon fiber market in the future. In October 2020, representatives of more than 400 wind energy companies around the world jointly issued the "Wind Energy Beijing Declaration", planning to add more than 50 million kilowatts of installed capacity in 2020-2025.
Nyob rau hauv cov ntsiab lus ntawm kev nthuav dav ntawm kev tsim khoom los ntawm cov tuam txhab cua fais fab loj, kev siv cov pa roj carbon fiber ntau hauv cov cua turbines tseem tsis tau dov tawm ntawm qhov loj, thiab tsuas yog lub ntiaj teb cua fais fab loj loj Vestas tau tsim ib qho loj - daim ntawv thov scale. Raws li lwm lub tuam txhab cua fais fab tsim cov ntawv thov rau carbon fiber composites, qhov kev thov rau carbon fiber nyob rau hauv lub tshuab fais fab kev lag luam yuav loj hlob exponentially. Nws kwv yees tias los ntawm 2025, tag nrho cov kev thov rau carbon fiber nyob rau hauv lub ntiaj teb no yuav ntau tshaj 200, 000 tons, sib npaug rau ib xyoos twg ntawm kev loj hlob ntawm 13.3 feem pua.
