Enkathini yanamuhla yokuthuthuka okusheshayo kwezobuchwepheshe, izinhlanganisela ze-carbon fiber zizenzela igama emikhakheni eminingi ngenxa yokusebenza kwazo okuphezulu. Kusukela ekusetshenzisweni okuphezulu ezindiza kuya ezidingweni zansuku zonke zezimpahla zemidlalo, izinhlanganisela ze-carbon fiber zibonise amandla amakhulu. Kodwa-ke, ukulungiselela izinhlanganisela ze-carbon fiber ezisebenza kahle kakhulu, ukwelashwa kokusebenza kwe-imicu yekhabhonikuyisinyathelo esibalulekile.
Isithombe se-microscope ye-electron ebusweni be-carbon fiber
I-carbon fiber, into esetshenziswa kakhulu yi-fiber, inezakhiwo eziningi ezikhangayo. Yakhiwe kakhulu yi-carbon futhi inesakhiwo eside se-filamentary. Ngokombono wesakhiwo sobuso, ubuso be-carbon fiber bubushelelezi futhi bunamaqembu ambalwa asebenzayo. Lokhu kungenxa yokuthi ngesikhathi sokulungiselela i-carbon fibers, i-carbonization yokushisa okuphezulu kanye nezinye izindlela zokwelapha kwenza ubuso be-carbon fibers bube nesimo esingenamsebenzi. Lesi sakhiwo sobuso siletha uchungechunge lwezinselele ekulungiseleleni i-carbon fiber composites.
Ubuso obubushelelezi benza isibopho phakathi kwe-carbon fiber nezinto ze-matrix sibe buthaka. Ekulungiseleleni izinto ezihlanganisiwe, kunzima ukuthi izinto ze-matrix zakhe isibopho esiqinile ebusweni be-i-carbon fiber, okuthinta ukusebenza okuphelele kwezinto ezihlanganisiwe. Okwesibili, ukuntuleka kwamaqembu asebenzayo asebenzayo kunciphisa ukusabela kwamakhemikhali phakathi kwezintambo zekhabhoni nezinto ze-matrix. Lokhu kwenza ukubophana phakathi kwezinto ezimbili kuncike kakhulu emiphumeleni yomzimba, njengokushumeka komshini, njll., okuvame ukungazinzile ngokwanele futhi okuthambekele ekuhlukaneni lapho kulawulwa amandla angaphandle.
Umdwebo weskimu wokuqinisa indwangu ye-carbon fiber phakathi kwezingqimba ngama-carbon nanotubes
Ukuze kuxazululwe lezi zinkinga, ukwelashwa kokusebenza kwe-carbon fibers kuyadingeka.imicu yekhabhonibonisa izinguquko ezibalulekile ezicini eziningana.
Ukwelashwa kokuvuselela kwandisa ubulukhuni bomphezulu wemicu yekhabhoni. Ngokusebenzisa i-oxidation yamakhemikhali, ukwelashwa nge-plasma nezinye izindlela, imigodi emincane kanye nemifantu kungaqoshwa ebusweni bemicu yekhabhoni, okwenza umphezulu ube nobulukhuni. Lo mphezulu obulukhuni wandisa indawo yokuxhumana phakathi kwe-carbon fiber kanye nezinto ezingaphansi komhlaba, okuthuthukisa isibopho somshini phakathi kwalokhu okubili. Lapho izinto ze-matrix ziboshelwe ku-carbon fiber, zikwazi kangcono ukuzishutheka kulezi zakhiwo ezilukhuni, zakha isibopho esiqinile.
Ukwelashwa kokuvuselela kungaletha inqwaba yamaqembu asebenzayo asabelayo ebusweni be-carbon fiber. La maqembu asebenzayo angasabela ngamakhemikhali namaqembu asebenzayo ahambisanayo ezintweni ze-matrix ukuze akhe izibopho zamakhemikhali. Isibonelo, ukwelashwa nge-oxidation kungaletha amaqembu e-hydroxyl, amaqembu e-carboxyl kanye namanye amaqembu asebenzayo ebusweni be-carbon fibers, angasabela nge-i-epoxyamaqembu ku-resin matrix nokunye ukuze akhe izibopho ze-covalent. Amandla alokhu kubopha kwamakhemikhali aphezulu kakhulu kunalawo okubopha ngokomzimba, okuthuthukisa kakhulu amandla okubopha phakathi kwe-carbon fiber nezinto ze-matrix.
Amandla angaphezulu e-activated carbon fiber nawo anda kakhulu. Ukwanda kwamandla angaphezulu kwenza kube lula ukuthi i-carbon fiber imanziswe yi-matrix material, ngaleyo ndlela kube lula ukusabalala nokungena kwezinto ze-matrix ebusweni be-carbon fiber. Enkambisweni yokulungiselela izinto ezihlanganisiwe, izinto ze-matrix zingasatshalaliswa ngokulinganayo eduze kwe-carbon fiber ukuze zakhe isakhiwo esiminyene kakhulu. Lokhu akugcini nje ngokuthuthukisa izakhiwo zemishini zezinto ezihlanganisiwe, kodwa futhi kuthuthukisa nezinye izakhiwo zayo, njengokumelana nokugqwala kanye nokuqina kokushisa.
Imicu ye-carbon esebenzayo inezinzuzo eziningi zokulungiselela izinhlanganisela ze-carbon fiber.
Ngokuphathelene nezakhiwo zemishini, amandla okubopha phakathi kwe-interfacial phakathi kwe-activatedimicu yekhabhonifuthi izinto ze-matrix zithuthukiswa kakhulu, okwenza ama-composite akwazi ukudlulisa kangcono ukucindezeleka lapho ebhekene namandla angaphandle. Lokhu kusho ukuthi izakhiwo zemishini zama-composite ezifana namandla kanye ne-modulus zithuthukiswa kakhulu. Isibonelo, ensimini yezindiza, edinga izakhiwo zemishini eziphezulu kakhulu, izingxenye zezindiza ezenziwe ngama-composite e-carbon fiber activated ziyakwazi ukumelana nemithwalo emikhulu yokundiza futhi zithuthukise ukuphepha nokuthembeka kwendiza. Emkhakheni wezimpahla zemidlalo, njengezinhlaka zamabhayisikili, amaqembu egalofu, njll., ama-composite e-carbon fiber activated anganikeza amandla nokuqina okungcono, ngenkathi enciphisa isisindo futhi ethuthukisa ulwazi lwabadlali.
Ngokuphathelene nokumelana nokugqwala, ngenxa yokwethulwa kwamaqembu asebenzayo asabelayo ebusweni bemicu ye-carbon esebenzayo, la maqembu asebenzayo angakha ukubopha kwamakhemikhali okuzinzile kakhulu nezinto ze-matrix, ngaleyo ndlela kuthuthukiswe ukumelana nokugqwala kwezinhlanganisela. Kwezinye izimo zemvelo ezinzima, njengemvelo yasolwandle, imboni yamakhemikhali, njll., i-activatedizinhlanganisela ze-carbon fiberingamelana kangcono nokuguguleka kwezinto ezigqwalisayo futhi yandise impilo yesevisi. Lokhu kubaluleke kakhulu kwezinye imishini nezakhiwo ezisetshenziswa ezindaweni ezinzima isikhathi eside.
Ngokuphathelene nokuzinza kokushisa, ukubopha okuhle phakathi kwe-activated carbon fiber kanye nezinto ze-matrix kungathuthukisa ukuzinza kokushisa kwama-composite. Ngaphansi kwendawo yokushisa okuphezulu, ama-composite angagcina izakhiwo zemishini ezingcono kanye nokuzinza kobukhulu, futhi awathambekeli kakhulu ekuguqukeni nasekulimeni. Lokhu kwenza ama-activated carbon fiber composite abe namathuba amaningi okusetshenziswa ekusetshenzisweni kwezinga lokushisa eliphezulu, njengezingxenye zenjini yezimoto kanye nezingxenye ze-hot end zenjini yezindiza.
Ngokuphathelene nokusebenza kokucubungula, imicu ye-carbon esebenzayo inomsebenzi ophezulu wobuso kanye nokuhambisana kangcono nezinto ze-matrix. Lokhu kwenza kube lula ngezinto ze-matrix ukungena nokuphola ebusweni be-carbon fiber ngesikhathi sokulungiselela izinto ezihlanganisiwe, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokucubungula kanye nekhwalithi yomkhiqizo. Ngesikhathi esifanayo, ukuklanywa kwezinhlanganisela ze-carbon fiber ezisebenzayo nakho kuyathuthukiswa, okuvumela ukuthi zenziwe ngokwezifiso zezinhlelo zokusebenza ezahlukene futhi zihlangabezane nezidingo ezahlukahlukene zobunjiniyela eziyinkimbinkimbi.
Ngakho-ke, ukwelashwa kokusebenza kwe-imicu yekhabhoniiyisixhumanisi esibalulekile ekulungiseleleni izinhlanganisela ze-carbon fiber ezisebenza kahle kakhulu. Ngokusebenzisa ukwelashwa kokuvuselela, isakhiwo sobuso be-carbon fiber singathuthukiswa ukuze kwandiswe ubulukhuni bobuso, kwethulwe amaqembu asebenzayo asebenzayo, futhi kuthuthukiswe amandla obuso, ukuze kuthuthukiswe amandla okubopha phakathi kwe-carbon fiber nezinto ze-matrix, futhi kubekwe isisekelo sokulungiselela izinhlanganisela ze-carbon fiber ezinezakhiwo ezinhle kakhulu zemishini, ukumelana nokugqwala, ukuzinza kokushisa kanye nokusebenza kokucubungula. Ngokuqhubeka kwesayensi nobuchwepheshe, kukholelwa ukuthi ubuchwepheshe bokuvuselela i-carbon fiber buzoqhubeka nokusungula izinto ezintsha nokuthuthukisa, bunikeze ukwesekwa okuqinile kokusetshenziswa kabanzi kwezinhlanganisela ze-carbon fiber.
