I-Carbon fiber inamandla athile aphezulu, i-modulus ethize ephezulu, ukumelana nokukhathala, ukumelana nokugqwala nezinye izakhiwo ezinhle kakhulu, ezisetshenziswa kabanzi ku-aerospace, imboni yezempi, imishini yezemidlalo neminye imikhakha. I-carbon fibre eqinisiwe i-polymerization

I-Carbon fiber inamandla athile aphezulu, i-modulus ethize ephezulu, ukumelana nokukhathala, ukumelana nokugqwala nezinye izakhiwo ezinhle kakhulu, ezisetshenziswa kabanzi ku-aerospace, imboni yezempi, imishini yezemidlalo neminye imikhakha. Izici zomshini zezinhlanganisela ze-polymer matrix ye-carbon fibre eziqiniswe kakhulu zincike kakhulu ezimpahleni zokuxhumanisa phakathi kwe-carbon fiber ne-matrix. Kodwa-ke, indawo ebushelelezi ye-carbon fiber, izici eziphezulu zemizwa kanye namaqembu ambalwa asebenzayo amakhemikhali kubangela ukuhlangana okubuthakathaka phakathi kwe-carbon fiber ne-matrix resin, futhi isigaba sokusebenzisana ngokuvamile siyisixhumanisi esibuthakathaka sezinto ezihlanganisiwe. I-interfacial microstructure ye-carbon fibre composite ihlobene eduze nezakhiwo ezihlangene. I-polarity yangaphezulu ye-carbon fiber ekugcineni ilele ku-morphology yangaphezulu ye-carbon fiber kanye nezinhlobo zamaqembu asebenzayo amakhemikhali. Kokubili ukwanda kwamaqembu asebenzayo kanye nokwanda kokuqina kwe-carbon fiber surface kusiza ekwandeni kwamandla e-carbon fibre surface. Izakhiwo ezingokoqobo ze-carbon fiber ikakhulukazi zihlanganisa i-surface morphology, ubukhulu be-groove engaphezulu kanye nokusabalalisa, ukuhwaqeka kwendawo, amandla angenawo angaphezulu nokunye. Ngokuphathelene ne-surface morphology, kunezimbotshana eziningi, ama-grooves, ukungcola kanye namakristalu ebusweni be-carbon fiber, enethonya elikhulu ezindaweni zokubopha izinto ezihlanganisiwe. I-chemical reactivity ye-carbon fiber surface ihlobene eduze nokugxila kwamaqembu asebenzayo, futhi la maqembu asebenzayo ikakhulukazi aqukethe i-oksijini yamaqembu asebenzayo njengeqembu elikhanyayo, iqembu le-spindle kanye neqembu le-epoxy. Inani lamaqembu asebenzayo ebusweni be-carbon fibre lincike endleleni yokwelapha ye-electrochemical engaphezulu kanye nezinga noma izinga lokushisa le-fiber carbonization. Isibonelo, ukwelashwa kwe-asidi kuzonikeza ifayibha amaqembu asebenzayo ahlukene kunokwelashwa kwe-alkali, futhi ezimweni ezifanayo zokwelashwa, izinga lokushisa eliphakeme le-carbonization, amaqembu asebenzayo ambalwa. I-modulus carbon fiber ephansi ngokuvamile inamaqembu asebenzayo kakhulu ngenxa yezinga layo eliphansi le-carbonization, ngakho-ke izosabela neqembu le-epoxy ekulungiseleleni izinhlanganisela ze-epoxy matrix, kuyilapho ukusabela kwe-high modulus carbon fiber system kungashaywa indiva, kanye ne-fiber ne-resin. ikakhulukazi abe nokusebenzisana okubuthakathaka. Ucwaningo oluningi lubonise ukuthi izakhiwo zokuhlanganisa zezinhlanganisela zingathuthukiswa ngempumelelo ngokulungisa i-interface microstructure yezinhlanganisela ngokuguqula indawo engaphezulu ye-carbon fibre, okungenye yezindawo ezithandwa kakhulu zocwaningo emkhakheni wezinto zokuhlanganisa i-carbon fibre cladding.
