Ts'ebetso e phahameng ea thepa ea carbon fiber e etsa hore e be le ts'ebetso e phahameng haholo ea kopo liindastering tse ngata.Ha thecarbon fibersehlahisoa se sebelisoa, ho fumanoa hore theko ea kakaretso e phahame.Sebaka seo theko ea sehlahisoa sa fiber e robehileng e leng holimo ho na le ho hong ho amanang le libaka tse ngata.Sehlopha sa rona se tla u bolella ho latela pono ea carbon fiber.
Lihlahisoa tsa carbon fiber tseo re li bonang li hlile li fapane haholo le lisebelisoa tsa rona tsa carbon fiber, hobane likhoele li ke ke tsa hlahisoa li le mong, 'me li tlameha ho kopanngoa le matrix a resin ho phethahatsa tlhahiso ea lihlahisoa.Le leng la mabaka a etsang hore theko ea lihlahisoa tsa faeba e be theko e boima haholo ke hore litšenyehelo tsa carbon filaments li batla li le holimo, kahoo re tlameha ho qala ka ho utloisisa thepa ea ho hula carbon fiber.
Ho na le mefuta e meraro ea fiber e robehileng, ho kenyelletsa polyacrylonitrile (PAN)-based carbon fiber, pitch-based carbon fiber le gum-based carbon fiber.Mokelikeli oa carbon fiber o tloaelehileng ka ho fetisisa oa PAN ke oona o tloaelehileng ka ho fetisisa, 'me karolo eohle ea mmaraka e feta 90%, kahoo thermoplastic carbon fiber ha e le hantle e bolela PAN-based carbon fiber.
Polyacrylonitrile le eona e qapiloe qalong.E qapiloe ke Akio Kondo oa Japane ka 1959, ebe e hlahisoa ka bongata Toray ka 1970. Polyacrylonitrile carbon filament eohle e na le matla a phahameng haholo le litšobotsi tsa naleli ea mohlala.Fiber e entsoeng ka asphalt e ile ea hlahisoa ke Univesithi ea Gunma Japane ka 1965. Leqhoa lena la carbon fiber le na le conductivity e phahameng haholo ea mocheso e phahameng ho feta 90OGPa, kahoo e sebelisoa haholo ho lisebelisoa tse khethehileng tse sebetsang.Fiber ea carbon e thehiloeng ho Viscose e ne e sebelisoa haholo-holo e le lisebelisoa tse kopantsoeng bakeng sa lithebe tsa mocheso oa sefofane ka bo-1950, hape ke thepa e tla sebelisoa hona joale.Kahoo re fumane hore tse peli tsa pele li qapiloe ke Majapane, ke ka lebaka leo tekanyo ea tekanyo ea ts'ebetso ea carbon fiber tow e thehiloeng ho Toray carbon fiber material.
Ehlile, lipatlisiso le nts'etsopele ea li-precursors tsa carbon fiber li ntse li tsoela pele lilemong tsa morao tjena, empa phello e akaretsang ha e so sebetse.Matsatsing ana, PAN-based e ntse e le eona ntho e ka sehloohong.Tlhahisong ea carbon filaments, tlhahiso ea carbon ea li-precursors tse tharo e ka fihla ho feta B80%.Ka khopolo, theko ea li-filaments tse joalo tsa carbon fiber e tla ba tlase, empa tlhahiso ea sekontiri se lokela ho hloekisoa le ho fetoloa.Ts'ebetso ena e tla eketsa haholo litšenyehelo tsa tlhahiso le ho fokotsa chai ho 30%.Kahoo tse thehiloeng ho PAN li ntse li tumme le ho feta.
Kahoo ha re shebeng fiber e sebelisoang haholo ea PAN carbon.Theko ea PAN-based carbon fiber e tlase haholo ho feta ea asphalt-based carbon fiber, 'me e ka sebelisoa masimong a mangata.Theko ea fiber e thehiloeng ho PAN bakeng sa lisathelaete e holimo ho 200 yen / kg, ha theko ea carbon fiber bakeng sa likoloi e tlaase ho 2,000 yen / kg.
Joale re ntse re sebelisa thepa ea carbon fiber ea Toray e le motheo.Mona, likhoele tse robehileng tse thehiloeng ho PAN li arotsoe ka lithapo tse kholo le tse nyane.Ka mohlala, litšenyehelo tsa 3K tse tloaelehileng ke lidolara tse 50-70 tsa US / kg, 'me litšenyehelo tsa 6K ke lidolara tse 4-50 tsa US / kg.Ka hona, re ka boela ra utloisisa hore na ke hobane'ng ha lithapo tse nyane li sebelisoa haholo libakeng tse sebetsang hantle haholo.
Ka hona, re re theko ea carbon fiber e tla ba theko e boima haholo.Hase ntle le lebaka hore e na le lintho tse ngata tse amanang le lihlahisoa tse tala.Ho phaella moo, theko ea lihlahisoa tsa carbon fiber e batla e phahame, 'me e amana haholo le taba ea hore lihlahisoa tsa rona tsa carbon fiber li hloka mosebetsi o mongata le lisebelisoa.
