Ikhabhoni ibalulekile ukuze zonke izinto eziphilayo ziphile, kuba yenza isiseko sazo zonke iimolekyuli eziphilayo, kwaye iimolekyuli zezinto eziphilayo zenza isiseko sezinto zonke eziphilayo.Nangona oku kukodwa kunomtsalane, ngophuhliso lwefayibha yekhabhoni, kutsha nje kufumene usetyenziso olutsha olumangalisayo kwi-aerospace, ubunjineli boluntu kunye nezinye iinkalo.Ifayibha yeCarbon yomelele, ilukhuni kwaye ikhaphukhaphu kunentsimbi.Ngoko ke, i-carbon fiber ithathe indawo yentsimbi kwiimveliso eziphezulu zokusebenza ezifana neenqwelo-moya, iimoto zokugijima kunye nezixhobo zemidlalo.
Iintsinga zekhabhoni zidla ngokudityaniswa nezinye izinto ukwenza imidibaniso.Enye yezinto ezidibeneyo yi-carbon fiber reinforced plastics (CFRP), edume ngamandla ayo obunzima, ukuqina kunye namandla aphezulu kumlinganiselo wobunzima.Ngenxa yeemfuno eziphezulu ze-carbon fiber composites, abaphandi baye baqhuba izifundo ezininzi zokuphucula amandla e-carbon fiber composites, uninzi lwazo lugxile kwitekhnoloji ekhethekileyo ebizwa ngokuba "yi-fiber oriented design", ephucula amandla ngokwandisa i-orientation. imicu.
Abaphandi kwiYunivesithi yaseTokyo yesayensi baye bamkela indlela yokuyila i-carbon fiber eyenza ukuqhelaniswa kunye nobukhulu befayibha, ngaloo ndlela iphucula amandla eplastiki eyomeleziweyo kunye nokuvelisa iiplastiki ezilula kwinkqubo yokuvelisa, inceda ukwenza iinqwelomoya ezikhaphukhaphu kunye neemoto.
Nangona kunjalo, indlela yoyilo yokhokelo lwefiber ayikho ngaphandle kweentsilelo.Uyilo lwesikhokelo sefayibha lukhulisa kuphela isalathiso kwaye lugcine ubungqingqwa befayibha buzinzileyo, nto leyo ethintela ukusetyenziswa ngokupheleleyo kweepropathi zoomatshini zeCFRP.UGqr ryyosuke Matuzaki weYunivesithi yaseTokyo yeSayensi (TUS) uchaza ukuba uphando lwakhe lugxile kwizinto ezidibeneyo.
Kulo mxholo, uGqr. Matsuzaki kunye noogxa bakhe uYuto Mori kunye noNaoya kumekawa kwi-tus bacebise indlela entsha yoyilo, enokuthi ngaxeshanye ikhulise ukuqhelaniswa kunye nobukhulu bemicu ngokwendawo yabo kwisakhiwo esidibeneyo.Oku kubavumela ukuba banciphise ubunzima beCFRP ngaphandle kokuchaphazela amandla ayo.Iziphumo zabo zipapashwa kwijenali yesakhiwo esiyintlanganisela.
Indlela yabo inamanyathelo amathathu: ukulungiselela, ukuphindaphinda, kunye nohlengahlengiso.Kwinkqubo yokulungiselela, uhlalutyo lokuqala lwenziwa ngokusebenzisa indlela ye-finite element (FEM) ukumisela inani leeleya, kunye novavanyo lobunzima bomgangatho lufezekiswa ngoyilo lwesikhokelo sefiber yemodeli yomgca yomgca kunye nemodeli yokutshintsha ubukhulu.I-fiber orientation inqunywe ngulwalathiso loxinzelelo oluyintloko ngendlela yokuphindaphinda, kwaye ubuninzi bubalwa ngowona mbono woxinzelelo oluphezulu.Okokugqibela, guqula inkqubo yokuguqula i-accounting ye-manufacturability, dala kuqala ireferensi "yesiseko sefiber bundle" indawo efuna ukomelela okongeziweyo, kwaye emva koko umisele isalathiso sokugqibela kunye nobukhulu belungiselelo le-fiber bundle, basasaza ipakethe kumacala omabini isalathiso.
Ngexesha elifanayo, indlela ephuculweyo inokunciphisa ubunzima ngaphezu kwe-5%, kwaye yenze ukuba ukuhanjiswa komthwalo kusebenze ngokufanelekileyo kunokusebenzisa i-fiber orientation yodwa.
Abaphandi bayachulumanca zezi ziphumo kwaye bajonge phambili ekusebenziseni iindlela zabo zokunciphisa ngakumbi ubunzima beenxalenye zeCFRP zemveli kwixesha elizayo.UDkt. Matsuzaki uthe indlela yethu yokuyila idlulela ngaphaya koyilo lwendalo oludibeneyo ukwenza iinqwelomoya ezilula kunye neemoto, ezinceda ukugcina amandla kunye nokunciphisa ukukhutshwa kwekhabhoni dioxide.
