I-Carbon Fiber Composites: Umhlahlandlela Wokucubungula
Ukucubungula izinhlanganisela ze-carbon fiber (CF) kuyibhizinisi elikhohlisayo, uma kucatshangelwa ukuthi onjiniyela abaningi abacabanga ukukhiqiza noma ukuklama bavela ngemuva kokuklama izingxenye zensimbi.ibizwe nge-aluminiyamu emnyama, futhi ukwakheka kwayo nokwakhiwa kwayo kuye kwachazwa njengobuciko obumnyama.Kuyini ngempela?
Inhloso yalo mhlahlandlela wokuklama ukuhlinzeka ngolwazi olujwayelekile kanye nokucaciswa kwezinto eziyinhlanganisela ye-carbon fibre neminye imihlahlandlela yokuklama imikhiqizo engasindi esebenza kahle kakhulu enezinhlanganisela ze-carbon fibre.
Kungani i-Carbon Fiber
Izinhlanganisela ze-carbon fibre zinezakhiwo ezihlukile zomshini uma kuqhathaniswa nezinsimbi namapulasitiki afanayo.Impahla iqinile, iqinile, futhi ilula.Lezi zinhlanganisela ziyizinto ezikhethwayo ezinhlelweni zokusebenza lapho ukusebenza okungasindi & okuphakeme kubaluleke kakhulu, njengezingxenye zemikhumbi-mkhathi, izindiza zokulwa, nezimoto zomjaho.
Iyini i-Carbon Fiber Composites
Izinto ezihlanganisiwe zenziwe ngokuhlanganisa ukuqinisa (i-fiber) ne-matrix (i-resin), futhi le nhlanganisela ye-fiber kanye ne-matrix inikeza izici eziphakeme kunezinye zezinto zodwa.Entweni eyinhlanganisela, ifayibha ithwala iningi lomthwalo futhi inegalelo elikhulu ezimpahleni ezibonakalayo.I-resin isiza ukudlulisa umthwalo phakathi kwamafayibha, ivimbele imicu ukuthi ingabhibhi, futhi ibophe izinto zokwakha ndawonye.
Ibiza malini?
Ngokomlando, izinhlanganisela ze-carbon fiber ziye zamba eqolo, okunciphise ukusetshenziswa kwazo ezinhlelweni ezikhethekile kuphela.Kodwa-ke, kule minyaka eyishumi nesikhombisa edlule, njengoba ukusetshenziswa kunyukile futhi i-automation ezinqubweni zokukhiqiza kwenyukile, intengo ye-carbon fiber composite yehlile.Umphumela ohlangene wehlise izindleko zizonke zemikhiqizo ye-aluminium ephezulu.Namuhla, izinhlanganisela ze-carbon fibre ziyasebenza ngokwezomnotho ezinhlelweni eziningi ezifana nezimpahla zezemidlalo, izikebhe zokusebenza, izimoto ezisebenza kahle, kanye nemishini yezimboni esebenza kahle kakhulu.
Izinhlelo zokusebenza
Izinto ezihlanganisiwe ziguquguquka ngokwedlulele.Unjiniyela angakhetha ezinhlobonhlobo zemicu nama-resin ukuze athole izinto ezibonakalayo azifunayo.Futhi, ukujiya kwempahla kanye nokuma kwefiber kungathuthukiswa kuhlelo lokusebenza ngalunye.
Izinzuzo ze-carbon fibre composite yilezi:
1.Ukuqina okuqondile okuphezulu (ukuqina kuhlukaniswe ukuminyana)
2.Amandla athile aphezulu (amandla ahlukaniswe ukuminyana)
3.I-coefficient ephansi kakhulu yokwanda kwe-thermal (CTE)
4.X-ray esobala (ngenxa yesisindo sayo samangqamuzana aphansi)
Kukuziphi izinhlelo zokusebenza lapho izinhlanganisela ze-carbon fibre zisetshenziswa?
Ukuma okuyingqayizivele kwezinhlanganisela ze-carbon fiber enamandla akhethekile aphezulu, ukuqina, kanye ne-CTE ephansi kuzinikeza indawo eyingqayizivele ezindaweni eziningi zohlelo lokusebenza njengoba kukhonjisiwe kuthebula elingezansi:
Izicelo ezijwayelekile zezinhlanganisela ze-carbon fibre
Ulwazi Lomklamo
Izinhlanganisela ze-Carbon Fiber zibhekwa "njengezinto zomklami" ngoba izingxenye zingalungiswa ukuze zibe namandla kanye noma ukuqina emikhondweni nasezindaweni ezidingekayo.Lokhu kufezwa ngokubeka izinto ngendlela ehlelekile futhi kuqondiswe i-fiber direction ukuze ihambisane kangcono nezidingo.Futhi, ukuklama nokuguquguquka kokukhiqiza okuhlinzekwa yizinhlanganisela ze-carbon fiber kunikeza amathuba okuthuthukisa idizayini, efana nokuhlanganisa nokuhlanganisa izici eziningi endaweni, ukuze kuqhutshekwe nokunciphisa inani lengxenye ephelele.
Amathuluzi
Isikhunta sisetshenziselwa ukuchaza ukuma kwezingxenye eziyinhlanganisela.Ingxenye ehlanganisiwe izothatha zonke izimo nezici zesikhunta;ngakho-ke izinga lengxenye lithonywa kakhulu izinga lesikhunta.Isikhunta kungaba owesilisa noma owesifazane.Isikhunta sesifazane yisona esivame kakhulu futhi sizokhiqiza ingxenye enengaphandle elibushelelezi kuyilapho isikhunta sesilisa sizokhiqiza indawo yangaphakathi ebushelelezi.Kudingeka isikhunta esihambisanayo (owesilisa nowesifazane) uma ingxenye ihlanganiswa kusetshenziswa umshini wokucindezela.
Amathuluzi ezingxenye ezimbili, okuvame ukubizwa ngokuthi "i-clamshell"
Izibunjwa zingenziwa ngezinto eziyinhlanganisela, i-epoxy egcwele insimbi noma yenziwe ngomshini nge-aluminium noma insimbi.Uhlobo lwesikhunta nezinto ezisetshenziswayo zincike ohlotsheni lwengxenye kanye nenani lokukhiqiza.
Inqubo Yokukhiqiza
Ukukhiqizwa kwe-carbon fiber okuthuthukisiwe kuvame ukwenziwa kusetshenziswa i-pre-impregnated carbon fibre ene-thermoset resins.Izindlela ezimbili ezibalulekile ezisetshenziswayo yilezi:
1. Ukuhleleka kwezandla
Ukwakheka kwezandla kwempahla eyalukiwe ngaphambi kokumiliselwa kuseyingxenye enkulu yemboni yokukhiqiza eyinhlanganisela, edinga amakhono nolwazi lwabasebenzi ukuze bakhe ama-plies ayisicaba abe yizimo eziyinkimbinkimbi.Iyakwazi ukukhiqiza ukusebenza okuphezulu kanye nezingxenye eziyinkimbinkimbi kodwa ingaba inqubo ebizayo futhi eguquguqukayo kakhulu.
2. Ukubekwa Kwe-Fiber Okuzenzakalelayo (AFP)
Izinto eziyinhloko okufanele uzicabangele ububanzi befiber oyisebenzisayo kanye nerediyasi ye-roller ehlanganisiwe.
