Carbon fiber ke lentsoe le akaretsang bakeng sa likhoele tse nang le khabone e fetang 90%, 'me e reheletsoe ka lebaka la khabone e phahameng.Carbon fiber e na le mefuta e fapaneng e metle ea khabone ea elemental, joalo ka matla a khoheli a manyane, ho hanyetsa mocheso, ho hanyetsa mocheso oa mocheso, ho hanyetsa lik'hemik'hale le conductivity, joalo-joalo E na le fiber entanglement le thepa e babatsehang ea mochine.Haholo-holo, matla a eona a khethehileng le modulus e khethehileng ea elastic e phahame, 'me e khona ho mamella mocheso o phahameng oa 2000 tlas'a boemo ba ho arola oksijene.Ke thepa ea bohlokoa ea indasteri ea fiberglass'me e loketse ho matlafatsa lisebelisoa tse kopantsoeng, lisebelisoa tsa ablation, le lisebelisoa tsa ho thibela mocheso.Ena ke boitsebiso bo bocha bo hlahisitsoeng mathoasong a lilemo tsa bo-1960 'me joale e se e le boitsebiso bo bocha ba bohlokoa sechabeng sa kajeno.
Har'a lihlahisoa tsa boikhathollo, ts'ebeliso ea pele ea PAN carbon fiber ke molamu oa ho tšoasa litlhapi.Hona joale, tlhahiso ea selemo le selemo ea carbon fiber fishing rods e ka ba limilione tse 12, 'me palo ea carbon fiber e sebelisoang ke lithane tse ka bang 1,200.Tšebeliso ea carbon fiber lihlopheng tsa kolofo e qalile ka 1972. Hajoale, tlhahiso ea selemo le selemo ea fibra de carbon.mekhatlo ea kolofo lefatšeng ka bophara e ka ba libotlolo tse limilione tse 40, 'me tekanyo ea carbon fiber e lekana le lithane tse 2,000.Ho sebelisoa ha li-racket tsa tenese ho qalile ka 1974. Hona joale, lefatše le hlahisitse li-racket tsa carbon fiber tse ka bang limilione tse 4,5 selemong se fetileng, 'me tšebeliso ea carbon fiber e hloka lithane tse ka bang 500.Har'a lintho tse ling, carbon fiber e boetse e sebelisoa haholo lipapaling tsa ho thellisa, liketsoana tsa lehloa, lithupa tsa ski, bo-'mankhane ba baseball, lipapali tsa 'mileng le lipapaling tsa metsing.
Ho lemoha boima bo bobebe, ho hanyetsa mokhathala, ho hanyetsa kutu le lisebelisoa tse ling tsa carbon fiber, e sebelisoa haholo indastering ea lifofane.Lefapheng la ho fofa sebakeng, li-high-modulus carbon fibers li 'nile tsa sebelisoa ka lisathelaete tsa maiketsetso ka lebaka la boima ba tsona bo bobebe (rigidity) le mocheso oa mocheso oa botsitso ba dimensional.Lilemong tsa morao tjena, li ’nile tsa sebelisoa ho lisathelaete tsa puisano tse kang iridium.

3.Boemo ba tlhahiso ea lihlahisoa tsa carbon fiber naheng ea heso
Tlhahiso le tšebeliso ea fiber ea carbon naheng ea heso e ntse e le boemong ba pele.Bokhoni ba tlhahiso ea khabone ea lehae ea faeba e etsa feela hoo e ka bang 0.4% ea kakaretso ea tlhahiso eaphahameng tshebetso carbon faeba leselalefats'eng, 'me ho feta 90% ea tšebeliso ea malapeng e itšetlehile ka thepa e tsoang linaheng tse ling.Boleng ba selelekela sa PAN esale e le tšitiso e thibelang tlhahiso e kholo ea indasteri ea fiber ea carbon naheng ea heso.Ho phaella moo, kaha carbon fiber haesale e nkoa e le thepa ea bohlokoa, linaha tse tsoetseng pele li koaletsoe linaheng tse ka ntle.Ka hona, litsebi tsa indasteri li lumela hore ho matlafatsa lipatlisiso tsa mantlha ke motheo oa boqapi le mokhoa oa mantlha oa ho nts'etsapele indasteri ea lehae ea carbon fiber.
Naha ea heso e ile ea qala ho ithuta carbon fiber ho tloha lilemong tsa bo-1960 ho isa lilemong tsa bo-1970, hoo e batlang e le ho tsamaisana le lefatše.Ka mor'a lilemo tse fetang 30 tsa mosebetsi o boima, Khamphani ea Toray ea Japane e hlahisitse lihlahisoa tsa carbon fiber haufi le boemo ba T300, empa tlhahiso le boleng li ke ke tsa finyella tlhokahalo ea lehae, e leng hole le linaha tse ling.Ha ho bapisoa le boemo bo tsoetseng pele ba machaba, mathata a hlahelletseng a k'habone ea lehae ke matla a tlase a khabone, ho se ts'oane hantle le botsitso, 'me boemo ba nts'etsopele bo batla bo le lilemo tse 20 ho isa ho tse 30 kamora tsa linaha tse tsoetseng pele,' me tekanyo ea tlhahiso e nyane, lisebelisoa tsa tekheniki. e saletse morao, 'me katleho ea tlhahiso e fokola.
Hajoale, tlhahiso ea lefats'e ea fibra de carbon pret e ka ba lithane tse 35,000, 'me tlhoko ea selemo le selemo' marakeng oa Chaena e ka ba lithane tse 6,500.Ke moreki e moholo oa carbon fiber.Leha ho le joalo, tlhahiso ea China faeba ka 2007 e ne e le lithane tse ka bang 200 feela, haholo-holo lihlahisoa tse sa sebetseng hantle.Boholo ba indasteri bo itšetlehile ka thepa e tsoang linaheng tse ling, 'me theko e theko e boima haholo.Mohlala, 'maraka o tloaelehileng oa T300 o haelloa ke ts'ehetso ea tekheniki e nang le litokelo tse ikemetseng tsa thepa ea mahlale,' me likhoebo tsa lapeng ha li so tsebe theknoloji e felletseng ea carbon fiber core.Boleng, thekenoloji le tekanyo ea tlhahiso ea carbon fiber naheng ea heso e fapane haholo le ea linaheng tse ling.Har'a bona, thekenoloji e phahameng ea carbon fiber e sebetsa e le monopolise le ho thibeloa ke Japane le linaha tsa Bophirimela.Ka hona, ho nka nako e telele ho lemoha sebaka sa carbon fiber.Ka lebaka la khaello ea 'maraka, ho bile le "carbon fiber fever" Chaena lilemong tsa morao tjena,' me mekhatlo e mengata ea lipatlisiso tsa saense le likhoebo li qalile lipatlisiso tsa carbon fiber le merero ea indasteri ea lithane tse likete.
