Izinto ezilungileyo zokusebenza okuphezulu kwe-carbon fiber composite materials

Imathiriyeli edityanisiweyo ibhekisa kudidi olutsha lwemathiriyeli edityaniswayo ukusuka kwizinto ezahlukeneyo.Izinto zekhabhoni zefiber esihlala sithi ziyizinto ezidibeneyo kwaye zibizwa ngokuba "igolide elimnyama" kwizinto ezidibeneyo.Izixhobo zekhabhoni zefiber composite zenziwe nge-carbon fiber tow kunye nezixhobo zematrix.(Imathiriyeli yeMatrix efana nentlaka, iiseramikhi, isinyithi, njl.njl.) imathiriyeli edityanisiweyo, izibonelelo zokusebenza eziphezulu kakhulu zenza ukuvalwa kakuhle kwemathiriyeli yemveli.Eli nqaku liza kuthetha malunga neenzuzo eziphezulu zokusebenza kwezinto ze-carbon fiber composite.

1. Uxinzelelo oluphantsi kakhulu

Ubuninzi be-carbon E-dimensional composite material iphantsi kakhulu, ubuninzi bumalunga ne-1.5gcm3 kuphela.Xa kuthelekiswa nezinto zetsimbi, ezifana nentsimbi enobuninzi be-7.8gycm3 kunye ne-aluminium alloy ene-2.8glcm3 yoxinaniso, esi sibini sinokufumanisa ukuba izinto ze-carbon fiber composite zinobuninzi obuphantsi kakhulu, ubunzima obupheleleyo bemveliso eyenziwe ngolu hlobo. nayo ilula kakhulu, kwaye inesiphumo esihle kakhulu esikhaphukhaphu kwiinkalo ezininzi, nto leyo esebenza ngayo izinto zentsimbi zemveli ezingenayo.

⒉ amandla aphezulu kakhulu
Izinto zefiber ezaphukileyo zinomsebenzi onamandla kakhulu, onokufikelela kumandla obunzima be-350OMPa.Xa kuthelekiswa nentsimbi, amandla okuqina entsimbi yi-65OMPa, kwaye amandla okuqina e-aluminium alloy yi-42OMPa.Ngale ndlela, kunokufunyanwa ukuba ukusebenza kwamandla aphezulu e-carbon fiber kuhle kakhulu.Ephakamileyo, inokwenza ukusebenza kwamandla emveliso ihlangabezane ngokugqibeleleyo neemfuno zangaphambili zemveliso, nokuba i-carbon fiber i-anisotropic, iya kuhlala iphezulu kakhulu kunamandla emveliso yensimbi.

3. Ukumelana nokugqwesa okulungileyo

Imathiriyeli yeCarbon fiber inezibonelelo zokusebenza ezilungileyo kakhulu zokuxhathisa iasidi, ukuxhathisa kwealkali kunye nokumelana ne-oxidation, eyenza ukuba izinto zekhabhoni zefayibha zibe neengenelo zokusetyenziswa kokusingqongileyo okuninzi, okufana nokusingqongileyo okumanzi okanye iimveliso zecarbon fiber ezihlala zivezwa ngaphandle, akukho lula ukurusa. okanye ukubola kwefestile, kunye nokusebenza okuphezulu kakhulu kwesicelo.

4. Ukuchasana kwempembelelo elungileyo

Imathiriyeli yeCarbon fiber inefuthe elihle kakhulu lokuchasa.Emva kokuba yenziwe kwiimveliso zekhabhoni zefiber, inempembelelo entle kakhulu yokuxhathisa xa kukho ungquzulwano olukhulu.Ukuqinisekisa ukhuseleko lwemoto, kuba ngaphakathi kwemveliso ye-carbon fiber yi-carbon filament, edibeneyo ngokufanelekileyo kwizinto eziphathekayo ze-matrix, ukwenzela ukuba amandla ahlakazeke kakuhle xa kusetyenziswe amandla.

5. Ukusebenza kakuhle

Izinto zefayibha zekhabhoni zizuze ukuguquguquka kweentsinga kakuhle, nto leyo eyenza ukuba iimveliso zekhabhoni zefiber ezenziwe ngezinto zekhabhoni zefayibha zibe noyilo oluhle kakhulu, kwaye zinokuyilwa ngokuguquguqukayo ngokweemfuno zemveliso yabathengi, zenza ukusebenza kwayo yonke imveliso kube ngcono.Iyakwazi ukuhlangabezana neemfuno, kwaye inokuqhuba uyilo lwe-interlayer phakathi kwemveliso.Umzekelo, kukho uyilo lwesicelo olunjalo kwizixhobo zonyango kunye noololiwe ababaleka ngesantya esiphezulu.Inkwenkwezi ekhanyayo ibonakalisa ukusebenza ngcono, kwaye ikwanayo noyilo olufanelekileyo lomkhombandlela., ngoko ke kukulungele ngakumbi ukusetyenziswa kwangempela kwemveliso.

6. I-coefficient ephantsi yokwandiswa kwe-thermal

Izinto zekhabhoni zefiber zine-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, ekwanenzuzo yokusebenza kakuhle kakhulu kwezinye iimveliso ze-carbon fiber ezifuna ukuchaneka, ezifana neteleskopu, iirula ezichanekileyo, kuquka i-Xuan Renwei kwi-aerospace kunye nezinye iindawo.Iimveliso zinokwenza inzuzo yokusebenza iyonke ibe ngcono.
