Isiqubulo seOlimpiki-i-Citi us, i-Altius, i-Fortius-ithetha "phezulu", "yomelele" kwaye "ikhawuleza" ngesiLatini.La magama asetyenziswe kwiiOlimpiki zeHlobo kunye neParalympics kwimbali.Ukusebenza kwembaleki.Njengoko besanda abavelisi bezixhobo zemidlalo besebenzisa izixhobo ezidibeneyo, esi saci sisebenza ngoku kwizihlangu zemidlalo, iibhayisekile, kunye nazo zonke iintlobo zeemveliso kwibala lomdyarho namhlanje.Ngenxa yokuba izinto ezidibeneyo zinokunyusa amandla kwaye zinciphise ubunzima bezixhobo, ezinceda iimbaleki ukuba zisebenzise ixesha elifutshane kukhuphiswano kwaye zifumane iziphumo ezigqwesileyo.
Ngokusebenzisa i-Kevlar, i-aramid fiber esetyenziswa ngokuqhelekileyo kwiindawo ze-bulletproof, kwi-kayaks, inokuqinisekiswa ukuba isikhephe esakhiwe kakuhle sinokumelana nokuqhekeka nokuqhekeka.Xa izixhobo zegraphene kunye nekhabhoni fiber zisetyenziselwa amaphenyane kunye ne-hulls, azikwazi nje ukwandisa amandla okubaleka kwe-hull, ukunciphisa ubunzima, kodwa nokunyusa umgama wokutyibilika.
Xa kuthelekiswa nezinto zemveli, i-carbon nanotubes (CNTs) inamandla aphezulu kunye nokuqina okuthe ngqo, ngoko ke zisetyenziswa ngokubanzi kwizixhobo zemidlalo.Iimpahla zeWilson Sports (Wilson SportingGoods) zasebenzisa ama-nanomaterials ukwenza iibhola ze-tennis.Esi sixhobo sinokubangela ukulahlekelwa komoya xa ibhola ibetha, ngaloo ndlela inceda iibhola zigcine imilo yazo kwaye zivumele ukuba ziqhube ixesha elide.Iipolymers ezongeziweyo zeFiber zikwasetyenziswa ngokuqhelekileyo kwiirakethi zentenetya ukwandisa ukuguquguquka, ukuqina kunye nokusebenza.
Xa i-carbon nanotubes isetyenziselwa ukwenza iibhola zegalufa, zineenzuzo zamandla aphuculweyo, ukuqina kunye nokumelana nokugqoka.I-Carbon nanotubes kunye ne-carbon fibers nazo zisetyenziselwa kwiiklabhu zegalufa ukunciphisa ubunzima kunye ne-torque yeklabhu, ngelixa ukwandisa ukuzinza kunye nokulawula.
Abavelisi beklabhu yegalufa bamkela i-carbon fiber edityanisiweyo kunanini na ngaphambili, kuba izixhobo ezidibeneyo zinokufikelela ukulingana phakathi kwamandla, ubunzima, kunye nokubamba okuncinci xa kuthelekiswa nezixhobo zemveli.
Kule mihla, iibhayisekile endleleni zihlala zikhaphukhaphu kakhulu.Basebenzisa isakhiwo sesakhelo se-carbon fiber epheleleyo kwaye baxhotyiswe ngamavili e-disc ayenziwe ngeqhekeza elilodwa le-carbon fiber, elinciphisa kakhulu ubunzima bebhayisikile kwaye linciphisa ukunxiba kwamavili.Abanye abagijimi bade banxibe izicathulo ze-carbon fiber ukukhusela iinyawo zabo ngaphandle kokufumana ubunzima.
Ukongeza, i-carbon fiber iye yangena nakwiindawo zokuqubha.Umzekelo, inkampani yeempahla zokuqubha iArena isebenzisa i-carbon fiber kwiisuti zayo zomdyarho wetekhnoloji ephezulu ukunyusa ukuguquguquka, uxinzelelo kunye nokuqina.
Ibhloko yokuqala eyomeleleyo, engatyibilikiyo ibalulekile ukutyhala indadi ze-Olimpiki ukuba zirekhode isantya
Ukudubula
Imbali yezaphetha ezihlanganisiweyo ziphinda zilandelelwe emva kwamawaka eminyaka, xa iinkuni zazigqunywe ngeempondo kunye neembambo ukuxhathisa ingcinezelo kunye noxinzelelo.Isaphetha sangoku siqulathe umtya kunye nomqheba oxhotyiswe ngezixhobo ezijolisekileyo kunye nemivalo yokuzinzisa ethomalalisa ukungcangcazela xa utolo lukhutshwa.
Isaphetha kufuneka sibe namandla kwaye sizinze ukuvumela utolo ukuba lukhulule ngesantya esisondela kwi-150 mph.Izinto ezidibeneyo zinokubonelela ngolu bunzima.Ngokomzekelo, iHoyt Archery yaseSalt Lake City isebenzisa i-triaxial 3-D carbon fiber ejikeleze i-foam core yokwenziwa ukuphucula isantya kunye nokuzinza.Ukunciphisa ukungcangcazela nako kubalulekile.Umenzi waseKorea uWin&Win Archery utofa iresin ebotshelelwe kwimolekyuli ye-carbon nanotube kumalungu ayo ukunciphisa "ukuxhawula isandla" okubangelwa kungcangcazela.
Isaphetha asikuphela kwecandelo elihlanganisiweyo elenziwe ngobunjineli kakhulu kulo mdlalo.Utolo nalo lulungiswe kakuhle ukuze lufikelele usukelo.I-X 10 ye-arrowhead iveliswa yi-Easton ye-Salt Lake City ngokukodwa kwiMidlalo ye-Olimpiki, idibanisa amandla aphezulu e-carbon fiber kwi-alloy core.
ibhayisekile
Kukho imisitho yebhayisikile emininzi kwiMidlalo yeOlimpiki, kwaye izixhobo zomsitho ngamnye zahluke kakhulu.Nangona kunjalo, kungakhathaliseki ukuba umntu okhuphisanayo ukhwela ibhayisekile elandelwayo engabhulekiyo enamavili aqinileyo, okanye ibhayisekile yendlela eqhelekileyo, okanye iBMX eyomelele kakhulu kunye neebhayisekile zeentaba, ezi zixhobo zinento enye-isakhelo seCFRP.
Umkhondo olungelelanisiweyo kunye nebhayisekile yasendle ixhomekeke kwisakhelo se-carbon fiber kunye namavili ediski ukufezekisa ubunzima obuyimfuneko bokubaleka kwisekethe.
Abavelisi abafana ne-Felt Racing LLC e-Irvine, eCalifornia bachaza ukuba i-carbon fiber yinto ekhethiweyo kuyo nayiphi na ibhayisekile esebenza kakhulu namhlanje.Uninzi lweemveliso zayo, i-Felt isebenzisa imixube eyahlukeneyo yemodulus ephezulu kunye ne-ultra-high modulus unidirectional fiber materials kunye ne-nano Resin matrix yayo.
treka kwaye nendawo
Kwindawo yokuphumla, iimbaleki zixhomekeke kwizinto ezimbini ukuze zibatyhale ngaphezulu kwebha ethe tye kangangoko kunokwenzeka-indlela eyomeleleyo kunye nepali ebhetyebhetye.Iipali zeepali zisebenzisa iipali ze-GFRP okanye zeCFRP.
Ngokutsho kwe-US TEss x, umenzi we-Fort Worth, eTexas, i-carbon fiber inokunyusa ngokufanelekileyo ukuqina.Ngokusebenzisa ngaphezu kwe-100 iintlobo ezahlukeneyo zemicu kwi-design yayo ye-tubular, iyakwazi ukucokisa ngokuchanekileyo iimpawu zeentonga zayo ukufezekisa Ibhalansi yokukhanya okumangalisayo kunye nokubamba okuncinci.I-UCS, umenzi wepali zocingo eCarson City, Nevada, uthembele kwiinkqubo zeresin ukuphucula ukuqina kweepali zayo ze-prepreg epoxy unidirectional fiberglass.
