Isikhokelo sokuLungiswa kweCarbon Fiber Composites
IiComposites zeCarbon Fiber: Isikhokelo sokuLungisa
Ukusetyenzwa kwekhabhon fiber (CF) composite lishishini elinenkohliso, kuthathelwa ingqalelo iinjineli ezininzi ezicinga ukuvelisa okanye ukuyila zivela kwimvelaphi yokuyila iinxalenye zesinyithi.ibizwa ngokuba yi-aluminiyam emnyama, kwaye ukuyilwa kwayo kunye nokwenziwa kwayo kuye kwachazwa njengobugcisa abamnyama.Yintoni, ngokwenene?
Injongo yesi sikhokelo soyilo kukubonelela ngolwazi oluphangaleleyo kunye neenkcukacha malunga nemathiriyeli ye-carbon fiber composite kunye nezikhokelo ezithile zokuyila iimveliso ezinobunzima obuphezulu kunye ne-carbon fiber composite.
Kutheni iCarbon Fiber
Imidibaniso yefayibha yekhabhoni ineepropathi ezikhethekileyo zoomatshini xa kuthelekiswa nesinyithi kunye neeplastiki ezilinganayo.Izinto eziphathekayo zomelele, ziqinile, kwaye zikhaphukhaphu.Ezi zidityanisiweyo ziyimathiriyeli yokuzikhethela kwizicelo apho ukukhanya kunye nokusebenza okuphezulu kuyeyona nto iphambili, njengezixhobo zesiphekepheke, inqwelomoya yokulwa, kunye neemoto zogqatso.
Yintoni iCarbon Fiber Composites
Izinto ezidibeneyo zenziwe ngokudibanisa ukuqiniswa (i-fiber) kunye ne-matrix (i-resin), kwaye le ndibaniselwano yefiber kunye ne-matrix ibonelela ngeempawu eziphakamileyo kunezinye zezinto zodwa.Kwimathiriyeli edibeneyo, ifayibha ithwala uninzi lomthwalo kwaye inegalelo elikhulu kwizinto eziphathekayo.I-resin inceda ukuhambisa umthwalo phakathi kweentsinga, ikhusela iintsinga ukusuka kwi-buckling, kwaye ibophe izixhobo kunye.
Ibiza malini?
Ngokwembali, i-carbon fiber composites iye yabiza kakhulu, ethintele ukusetyenziswa kwayo kwizicelo ezikhethekileyo kuphela.Nangona kunjalo, kwiminyaka elishumi elinesixhenxe edlulileyo, njengoko ukusetyenziswa kuye kwanda kwaye i-automation kwiinkqubo zokuvelisa inyukile, ixabiso le-carbon fiber composite liye lancipha.Umphumo odibeneyo wehlise ixabiso elipheleleyo leemveliso eziphezulu ze-aluminium.Namhlanje, i-carbon fiber composites iyasebenza ngokwezoqoqosho kwizicelo ezininzi ezinje ngempahla yezemidlalo, izikhephe zokusebenza, iimoto zokusebenza, kunye noomatshini abasebenza kakhulu kwimizi-mveliso.
Usetyenziso
Iimathiriyeli ezihlanganisiweyo zininzi kakhulu.Injineli inokukhetha kwiintlobo ezininzi zeentsinga kunye nee-resin ukufumana izinto ezibonakalayo ezifunwayo.Kwakhona, ubukhulu bezinto eziphathekayo kunye nokuqhelaniswa nefayibha kunokwandiswa kwisicelo ngasinye.
Iingenelo zekhabhoni fiber composite zezi:
1.Ukuqina okuthe ngqo okuphezulu (ukuqina okwahlulahlulwe ngoxinaniso)
2.Amandla athile aphezulu (amandla ahlulwe ngoxinaniso)
3.I-coefficient ephantsi kakhulu yokwandiswa kwe-thermal (CTE)
I-4.X-ray ecacileyo (ngenxa yobunzima bayo obuphantsi bemolekyuli)
Zeziphi izicelo ezisetyenziswa kwikharbhon fiber composites?
Ukubekwa okukhethekileyo kwe-carbon fiber composites enamandla athile aphezulu, ukuqina, kunye ne-CTE ephantsi ibanika indawo ekhethekileyo kwiindawo ezininzi zesicelo njengoko kuboniswe kwitheyibhile engezantsi:
Ukusetyenziswa okuqhelekileyo kweekhompositi ze-carbon fiber
Ulwazi loyilo
Imidibaniso yeCarbon Fiber ijongwa "njengezinto zomyili" kuba iinxalenye zinokuthi zilungelelaniswe ukuba zibe namandla kunye okanye ukuqina kumkhombandlela kunye neendawo eziyimfuneko.Oku kuphunyezwa ngokubeka ngobuchule imathiriyeli kunye nokuqhelanisa umkhombandlela wefiber ukuze ulungele iimfuno.Kwakhona, ukuyila kunye nokuguquguquka kwemveliso enikezelwa yi-carbon fiber composites ibonelela ngamathuba okuphucula uyilo, njengokudibanisa kunye nokubandakanya iimpawu ezininzi kwi-situ, ukuqhubela phambili ukunciphisa ixabiso elipheleleyo.
izixhobo
Ukungunda kusetyenziselwa ukuchaza imilo yamalungu adibeneyo.Inxalenye edibeneyo iya kuthatha zonke iimilo kunye neempawu zokubumba;ngoko umgangatho wenxalenye uphenjelelwa kakhulu ngumgangatho wokubumba.Umngundo unokuba yindoda okanye ibhinqa.Izibungu ezibhinqileyo zezona zixhaphakileyo kwaye ziya kuvelisa indawo enomgangatho ogudileyo wangaphandle ngelixa ukungunda kwendoda kuya kuvelisa umphezulu ogudileyo wangaphakathi.Umngundo ohambelanayo (inkunzi nemazi) uyafuneka ukuba inxalenye idityaniswe kusetyenziswa ucinezelo.
Isixhobo esinamacandelo amabini, esibizwa ngokuba yi "clamshell"
Iimbumba zingenziwa ngezinto ezidibeneyo, i-epoxy egcwele isinyithi okanye ifakwe kwi-aluminium okanye intsimbi.Uhlobo lokubumba kunye nezinto ezisetyenzisiweyo zixhomekeke kuhlobo lwenxalenye kunye nobuninzi bemveliso.
Inkqubo yokuVelisa
Imveliso yefayibha yekhabhoni ephucukileyo idla ngokuqhutywa kusetyenziswa ifayibha yekhabhoni efakwe ngaphambili kunye ne-thermoset resins.Iindlela ezimbini eziphambili ezisetyenziswayo zezi:
1. Ulungelelwaniso lwezandla
Ulungelelwaniso lwezandla lwemathiriyeli elukiweyo ngaphambi kokumiliselwa kuseyinxenye enkulu yeshishini lemveliso edibeneyo, efuna izakhono kunye namava abasebenzi bokusebenza ukwenza iiplies ezisicaba zibe ziimo ezintsonkothileyo.Iyakwazi ukuvelisa ukusebenza okuphezulu kunye namalungu anzima kodwa ingaba yinkqubo ebiza kakhulu kwaye eguquguqukayo kakhulu.
2. Ukufakwa kweFayibha eZisebenzelayo (AFP)
Izinto eziphambili ekufuneka ziqwalaselwe bububanzi befiber oyisebenzisayo kunye neradius roller compaction.
