I-Carbon fiber iyi-fibrous carbon material ene-carbon content engaphezu kuka-90%.Ilungiswa ngokufaka i-carbonizing imicu ehlukahlukene yezinto eziphilayo ekushiseni okuphezulu kugesi engasebenzi.Inezici ezinhle kakhulu zemishini.Ikakhulukazi endaweni enezinga lokushisa eliphezulu elingaphezu kuka-2000 ℃, iyona kuphela into amandla ayo anganciphi.I-Carbon fibre coiled tube kanye ne-carbon fibre reinforced polymer (CFRP), njengezisetshenziswa ezintsha ekhulwini lama-21, zisetshenziswa kabanzi ezimotweni ngenxa yamandla azo aphezulu, i-modulus ephezulu yokunwebeka kanye namandla adonsela phansi akhethekile.
Ubuchwepheshe bokwenza ikhoyili ye-Carbon fiber yindlela yokwenza imikhiqizo eyinhlanganisela eyenziwe ngamaroli ashisayo e-carbon fiber prepreg ku-coiler.
Umgomo uwukusebenzisa amarola ashisayo emshinini wokusonta i-carbon fibre ukuthambisa i-prepreg futhi uncibilikise i-resin binder ku-prepreg.Ngaphansi kokushuba okuthile, ngesikhathi sokusebenza okujikelezayo kwerola, i-prepreg ilinyazwa ngokuqhubekayo kumongo weshubhu ngokusebenzisa ukungqubuzana phakathi kwe-roller ne-mandrel ize ifinyelele ubukhulu obufunayo, bese ipholiswa futhi ilolongelwe yi-roller ebandayo, kusukela ku-Susa. kusuka ku-winder bese uphulukisa kuhhavini ophilisayo.Ngemva kokuba ishubhu seliphulukisiwe, inxeba leshubhu elinezinto eziyinhlanganisela lingatholakala ngokususa umnyombo wangaphambili.Ngokwendlela yokudla ye-prepreg enqubweni yokubumba, ingahlukaniswa ngendlela yokondla okwenziwa ngesandla kanye nendlela yokudla eqhubekayo yomshini.Inqubo eyisisekelo imi kanje: Okokuqala, isigubhu siyahlanzwa, khona-ke isigubhu esishisayo sishiswa ekushiseni okumisiwe, futhi ukungezwani kwe-prepreg kulungiswa.Akukho ukucindezela ku-roller, bopha indwangu yokuhola esikhunjini esihlanganiswe ne-ejenti yokukhulula ukuphenduka oku-1, bese wehlisa i-roller yokucindezela, ubeke indwangu yekhanda lokuphrinta ku-roller eshisayo, ukhiphe i-prepreg, bese unamathisela i-prepreg ku-The Heated. ingxenye yendwangu yekhanda imboza ngendwangu yomthofu.Ubude bendwangu yomthofu bungaba ngu-800 ~ 1200 mm, kuye ngobubanzi bepayipi, ubude obudlulele bendwangu yomthofu kanye netheyiphu ngokuvamile i-150 ~ 250 mm.Lapho uhlanganisa ipayipi elinodonga oluwugqinsi, ngesikhathi sokusebenza okuvamile, phuthukisa ngokusesilinganisweni isivinini se-mandrel futhi wehlise ijubane.Ukuklama eduze nobukhulu bodonga, finyelela ubukhulu bomklamo, usike itheyipu.Khona-ke, ngaphansi kwesimo sokugcina ingcindezi ye-roller yokucindezela, i-mandrel ijikeleza ngokuqhubekayo emibuthanweni engu-1-2.Ekugcineni, phakamisa irola yokucindezela ukuze ulinganise ububanzi bangaphandle beshubhu elingenalutho.Ngemuva kokuphumelela ukuhlolwa, ikhishwa ku-carbon fibre coiler futhi ithunyelwe esithandweni somlilo ukuze ipholiswe futhi ibunjwe.
Iphedi yokushisisa isihlalo
I-Carbon fibre auto sheet heat pad iyimpumelelo ekusetshenzisweni kokushisisa kwe-carbon fibre embonini yezimoto.Ubuchwepheshe besici sokushisisa i-Carbon fiber buya ngokuya buthandwa kakhulu emakethe eyisiza yezimoto, bungena esikhundleni ngokuphelele sohlelo lokushisisa amashidi.Njengamanje, cishe zonke izimoto ezisezingeni eliphezulu neziwubukhazikhazi zabakhiqizi bezimoto emhlabeni zifakwe imishini yokushisa izihlalo, njengeMercedes-Benz, BMW, Audi, Volkswagen, Honda, Nissan nokunye.Umthwalo wokushisa we-Carbon fibre I-Carbon fiber iyimpahla ebamba ukushisa esebenza kahle kakhulu esebenza kahle ngokushisa efinyelela ku-96%, isatshalaliswa ngokulinganayo endaweni yokushisisa.
Ukusabalalisa okufanayo kuqinisekisa ukukhishwa kokushisa okufanayo endaweni yokushisa isihlalo, i-carbon fiber filaments kanye nokusabalalisa ukushisa okufanayo, kanye nokusetshenziswa kwesikhathi eside kwephedi lokushisa kuqinisekisa ukuthi isikhumba esisesikhundleni esiphezulu sibushelelezi futhi siphelele.Awekho amamaki omugqa nokushintsha kombala okwenziwe kwasendaweni.Uma izinga lokushisa lidlula ibanga elimisiwe, amandla azonqanyulwa ngokuzenzakalelayo.Uma izinga lokushisa lingakwazi ukuhlangabezana nezidingo, amandla azovulwa ngokuzenzakalelayo ukuze kulungiswe izinga lokushisa.I-Carbon fiber ifanele amaza amaza e-infrared amuncwa umzimba womuntu futhi inemiphumela yokunakekelwa kwezempilo.Kunganciphisa ngokugcwele ukukhathala kokushayela futhi kuthuthukise ukunethezeka.
Umzimba wemoto, chassis
Njengoba izinhlanganisela ze-polymer eziqiniswe nge-carbon fibre zinamandla anele nokuqina, zifanele ukwenza izinto ezilula zezingxenye eziyinhloko zesakhiwo njengomzimba kanye ne-chassis.Ukusetshenziswa kwe-carbon fiber composite materials kulindeleke ukuthi kunciphise isisindo somzimba wemoto kanye ne-chassis ngo-40% kuya ku-60%, okulingana ne-1/3 kuya ku-1/6 yesisindo sesakhiwo sensimbi.I-Materials Systems Laboratory yase-UK yafunda imiphumela yokuncipha kwesisindo yezinhlanganisela ze-carbon fiber.Imiphumela yabonisa ukuthi isisindo se-carbon fiber reinforced polymer material sasingu-172 kg kuphela, kanti isisindo somzimba wensimbi sasingu-368 kg, cishe u-50% wokunciphisa isisindo.Uma umthamo wokukhiqiza ungaphansi kwezimoto ezingu-20,000, izindleko zokukhiqiza indikimba eyinhlanganisela usebenzisa inqubo ye-RTM iphansi kuneyomzimba wensimbi.I-Toray isungule ubuchwepheshe bokubumba i-chassis yemoto (isitezi esingaphambili) kungakapheli imizuzu eyi-10 isebenzisa ipulasitiki eqiniswe nge-carbon fiber (CFRP).Kodwa-ke, ngenxa yezindleko eziphezulu ze-carbon fibre, ukusetshenziswa kwe-carbon fibre composite materials ezimotweni kunomkhawulo, futhi isetshenziswa kuphela kwezinye izimoto zomjaho i-F1, ezimotweni ezisezingeni eliphezulu, namamodeli anevolumu encane, njengemizimba I-BMW's Z-9 ne-Z-22, i-M3 series Roof nomzimba, umzimba we-G&M's Ultralite, umzimba we-Ford's GT40, umzimba othwala umthwalo we-Porsche 911 GT3, njll.
Ithangi lokugcina amafutha
Ukusetshenziswa kwe-CFRP kungafinyelela imikhumbi yengcindezi engasindi ngenkathi ihlangabezana nale mfuneko.Ngokuthuthukiswa kwezimoto zemvelo, ukusetshenziswa kwezinto ze-CFRP ukwenza amathangi kaphethiloli ezimoto ze-hydrogen fuel cell sekwamukelwe yimakethe.Ngokolwazi lweFuel Cell Seminar yeJapan Energy Agency, izimoto eziyizigidi ezi-5 eJapan zizosebenzisa ama-fuel cell ngo-2020. Imoto yase-American Ford Humerhh2h yase-off-road nayo isiqalile ukusebenzisa ama-hydrogen fuel cell, kanti kulindeleke ukuthi i-hydrogen fuel izimoto zamaselula zizofinyelela usayizi wemakethe othize.
Okungenhla okuqukethwe okuyinhloko kwesicelo sezingxenye ze-carbon fibre auto ezethulwe kuwe.Uma ungazi lutho ngakho, sicela uze uzobheka iwebhusayithi yethu, futhi sizoba nabantu abangochwepheshe abazokuchazela ngakho.
