Ukusebenza okuphezulu kwe-carbon fiber material kuyenza ibe nokusebenza okuphezulu kakhulu kwesicelo ezimbonini eziningi.Lapho i-i-carbon fiberumkhiqizo usetshenziswa, kutholakala ukuthi intengo iyonke iphezulu.Indawo lapho intengo yomkhiqizo wefayibha ephukile iphezulu ihlobene nezindawo eziningi.Ithimba lethu lizokutshela ngombono we-carbon fiber.
Imikhiqizo ye-carbon fiber esiyibonayo empeleni ihluke kakhulu ezintweni zethu ze-carbon fiber, ngoba imicu ayikwazi ukukhiqizwa yodwa, futhi kufanele ihlanganiswe ne-resin matrix ukuze kuqedelwe ukukhiqizwa kwemikhiqizo.Esinye sezizathu ezenza intengo yemikhiqizo yefayibha ibize kakhulu ukuthi izindleko ze-carbon filaments ziphezulu uma kuqhathaniswa, ngakho-ke kufanele siqale siqonde i-carbon fiber tow material.
Kunezinhlobo ezintathu ze-fiber tow ephukile, okuhlanganisa i-polyacrylonitrile (PAN)-based carbon fiber, i-pitch-based carbon fiber kanye ne-gum-based carbon fiber.Ifayibha ye-carbon esekelwe ku-PAN evame kakhulu iyona evame kakhulu, futhi isabelo semakethe sonke singaphezu kuka-90%, ngakho-ke i-thermoplastic carbon fiber yamanje ibhekisela ku-PAN-based carbon fiber.
I-Polyacrylonitrile nayo yasungulwa ekuqaleni.Yasungulwa ngu-Akio Kondo eJapane ngo-1959, futhi yakhiqizwa ngobuningi eToray ngo-1970. Yonke i-polyacrylonitrile carbon filament inamandla amakhulu kakhulu kanye nezici zenkanyezi eyimodeli.I-fiber esekelwe ku-asphalt yathuthukiswa yi-Gunma University e-Japan ngo-1965. Le carbon fiber tow ine-conductivity ephezulu kakhulu ye-thermal ephakeme njenge-90OGPa, ngakho-ke isetshenziswa kakhulu ezintweni zokusebenza ezikhethekile.I-carbon fiber esekelwe ku-Viscose yayisetshenziswa ngokuyinhloko njengento eyinhlanganisela yezihlangu zokushisa zemikhumbi-mkhathi ngeminyaka yawo-1950, futhi iyimpahla ezosetshenziswa manje.Ngakho-ke sithole ukuthi ezimbili zokuqala zasungulwa amaJapane, yingakho izinga lokulinganisa ukusebenza kwe-carbon fibre tow lisekelwe ku-Toray carbon fiber material.
Yebo, ucwaningo nokuthuthukiswa kwe-carbon fibre tow precursors luqhubekile nokuthuthuka eminyakeni yamuva, kodwa umphumela uwonke awukasebenzi.Namuhla, i-PAN-based kuseyinsika.Ekukhiqizeni ama-carbon filaments, isivuno sekhabhoni yezandulela ezintathu singafinyelela ngaphezu kwe-B80%.Ngokwethiyori, intengo ye-carbon filaments enjalo izoba phansi, kodwa ukukhiqizwa kwe-pitch-based kudinga ukucwengwa futhi kulungiswe.Lolu hlelo luzonyusa kakhulu izindleko zokukhiqiza futhi lunciphise isivuno sibe ngama-30%.Ngakho-ke ezisekelwe ku-PAN zisathandwa kakhulu.
Ngakho-ke ake sibheke i-PAN carbon fiber esetshenziswa kabanzi.Intengo ye-PAN-based carbon fiber iphansi kakhulu kunaleyo ye-asphalt-based carbon fiber, futhi ingasetshenziswa emikhakheni eminingi.Intengo yefiber esekwe ku-PAN yamasathelayithi iphezulu ngokufinyelela ku-200 yen/kg, kanti intengo ye-carbon fiber ezimotweni iphansi njenge-2,000 yen/kg.
Bese sisasebenzisa i-Toray's carbon fiber material njengesisekelo.Lapha, imicu ephukile esekelwe ku-PAN ihlukaniswa ngamathowuzi amakhulu namancane.Isibonelo, izindleko ze-3K ezivamile zingama-50-70 US dollar/kg, kanti izindleko ze-6K zingama-4-50 US dollar/kg.Ngakho-ke, singaphinde siqonde ukuthi kungani amathowuzi amancane asetshenziswa kakhulu emikhakheni esebenza kahle kakhulu.
Ngakho-ke, sithi intengo ye-carbon fiber izobiza kakhulu.Akukhona ngaphandle kwesizathu ukuthi kuningi okwenzayo ngezinto zokusetshenziswa.Ngaphezu kwalokho, intengo yemikhiqizo ye-carbon fiber iphezulu uma kuqhathaniswa, futhi ihlobene kakhulu neqiniso lokuthi imikhiqizo yethu ye-carbon fiber idinga umsebenzi omningi kanye nemishini.
