Ikhabhoni ibalulekile ukuze zonke izinto eziphilayo ziphile, ngoba yakha isisekelo sawo wonke ama- molecule ephilayo, kanti ama- molecule ephilayo akha isisekelo sazo zonke izinto eziphilayo.Yize lokhu kukodwa kuhlaba umxhwele impela, ngokuthuthukiswa kwe-carbon fiber, muva nje kusanda kuthola izinhlelo ezintsha ezimangazayo ku-aerospace, ubunjiniyela bomphakathi kanye neminye imikhakha.I-carbon fiber inamandla, ilukhuni futhi ilula kunensimbi.Ngakho-ke, i-carbon fiber ithathe indawo yensimbi emikhiqizweni esebenza kahle njengezindiza, izimoto zomjaho kanye nemishini yezemidlalo.
Imicu ye-carbon ngokuvamile ihlanganiswa nezinye izinto zokwakha izinhlanganisela.Enye yezinto eziyinhlanganisela i-carbon fibre reinforced plastics (CFRP), edume ngamandla ayo aqinile, ukuqina kanye namandla aphezulu okulinganisa isisindo.Ngenxa yezidingo eziphakeme zezinhlanganisela ze-carbon fiber, abacwaningi benze izifundo ezimbalwa zokuthuthukisa amandla enhlanganisela ye-carbon fibre, iningi lazo eligxile kubuchwepheshe obukhethekile obubizwa ngokuthi "i-fiber oriented design", ethuthukisa amandla ngokwenza kahle imicu.
Abacwaningi baseYunivesithi yaseTokyo yesayensi basebenzise indlela yokuklama i-carbon fibre eyenza kahle ukuma nokuqina kwefayibha, ngaleyo ndlela ithuthukise amandla amapulasitiki aqiniswe ngefayibha futhi ikhiqize amapulasitiki alula enqubweni yokukhiqiza, okusiza ukwenza izindiza ezilula nezimoto.
Kodwa-ke, indlela yokuklama yokuqondisa i-fiber ayinakho ukushiyeka.Idizayini yomhlahlandlela wefayibha ithuthukisa isiqondiso kuphela futhi igcine ukujiya kwefayibha kugxilile, okuvimbela ukusetshenziswa okugcwele kwezakhiwo zemishini ze-CFRP.UDkt ryyosuke Matuzaki waseTokyo University of Science (TUS) uchaza ukuthi ucwaningo lwakhe lugxile ezintweni eziyinhlanganisela.
Kulo mongo, uDkt. Matsuzaki kanye nozakwabo u-Yuto Mori kanye no-Naoya kumekawa in tus bahlongoza indlela entsha yokuklama, engakwazi ngesikhathi esisodwa ukuthuthukisa ukuma nokujiya kwemicu ngokuya ngokuma kwayo esakhiweni esiyinhlanganisela.Lokhu kuvumela ukuba banciphise isisindo se-CFRP ngaphandle kokuthinta amandla ayo.Imiphumela yabo ishicilelwa kujenali yesakhiwo esiyinhlanganisela.
Indlela yabo inezinyathelo ezintathu: ukulungiselela, ukuphindaphinda, nokuguqulwa.Enqubweni yokulungiselela, ukuhlaziya kokuqala kwenziwa kusetshenziswa indlela yesici esinqunyiwe (i-FEM) ukuze kutholwe inani lezendlalelo, futhi ukuhlolwa kwesisindo sekhwalithi kubonakala ngomklamo womhlahlandlela wefayibha wemodeli yomugqa wokulinganisa kanye nemodeli yokushintsha ukushuba.I-fiber orientation inqunywa isiqondiso sokucindezeleka okuyinhloko ngendlela ephindaphindayo, futhi ubukhulu bubalwa ngethiyori yokucindezeleka enkulu.Okokugcina, lungisa inqubo ukuze uguqule ukubalwa kwezimali kokwenziwa, qala ngokudala indawo eyinkomba "inqwaba ye-fiber bundle" edinga amandla angeziwe, bese unquma isiqondiso sokugcina nokuqina kwenqwaba ye-fiber yohlelo, basakaza iphakheji nhlangothi zombili ze-fiber bundle. ireferensi.
Ngesikhathi esifanayo, indlela elungiselelwe inganciphisa isisindo ngaphezu kuka-5%, futhi yenze ukusebenza kahle kokudlulisa umthwalo kuphakame kunokusebenzisa i-fiber orientation kuphela.
Abacwaningi bajabule ngale miphumela futhi babheke phambili ekusebenziseni izindlela zabo ukuze baqhubeke nokunciphisa isisindo sezingxenye ze-CFRP zendabuko esikhathini esizayo.UDkt. Matsuzaki uthe indlela yethu yokuklama idlula ukwakheka kwenhlanganisela evamile ukuze senze izindiza ezilula nezimoto, okusiza ukonga amandla nokunciphisa ukukhishwa kwe-carbon dioxide.
