Zonke iintlobo zemathiriyeli zisetyenziswa ekuprintweni kwe3D kwezi ntsuku, i-Kevlar kunye ne-fiberglass eqinise iinylon. njl. Kodwa ngelixa kuyinyani oko ukomelela kwezixhobo kubalulekile, kunjalo nakulwakhiwo lwangaphakathi lwento 3D eprintiweyo. Kutshanje, iqela labaphandi I-MIT iphuhlise enye yezona zinto zomeleleyo kunye nezona zikhanyayo Ngokucinezela kunye nokunyibilikisa amasuntswana egraphene.
Kude kube ngoku, abaphandi bekunobunzima ekuguquleni amandla ombini we-graphene abe ngamacandelo amathathu. Kodwa uyilo olutsha ukusuka kwi-MIT, a Ukucwangciswa kwe-graphene efanayo ne Isiponji, sinokuphindaphindeka kalishumi kunentsimbi, sinoxinano lweepesenti ezintlanu kuphela.
Iziphumo zeqela le-MIT zophando ziye zaxelwa kutshanje Kwiphephancwadi leNzululwazi. Inqaku lalibhalwe ngokubhaliweyo nguMarkus Buehler, McAfee uprofesa wobunjineli kunye nentloko ye-MIT yeSebe lezoBunjineli boLuntu nezoBunjineli (i-CEE); Umphandi wenzululwazi weCEE uZhao Qin; Umfundi ophumelele isidanga uGang Seob Jung; Kwaye uMin Jeong Kang Meng, udidi luka-2016.
Kwijometri yesakhiwo seGraphene ngundoqo
Iziphumo zabo, ngokwe-MIT, zityhila ukuba "eyona nto ibalulekileyo kwiimilo ezintsha ze-3D inento yokwenza nokuqwalaselwa kwayo okungaqhelekanga kwejiyometri Ngaphandle kwezinto ngokwazo, eziphakamisa ukuba iipropathi ezifanayo zinokufumaneka kwizinto ezahlukeneyo ukuba sisebenzisa iimpawu ezifanayo zejiyometri. »
Iqela livelise uzinzo kunye nesakhiwo esomeleleyo esifana nekorale kunye nezidalwa ezincinci ezaziwa njengeediatom, usebenzisa indibaniselwano yobushushu kunye noxinzelelo lokucinezela iiflakes ezincinci zegraphene. Iimilo eziphumela zinendawo enkulu yomhlaba ngokulingana nomthamo wazo, kwaye zomelele ngokungaqhelekanga. Zijongeka njengeebhola zeNerf - zizinto ezirhangqiweyo, kodwa zizele yimingxunya. Ezi ntlobo zintsonkothileyo zaziwa ngokuba zii-gyroids., Kwaye uBuehler wathi "mhlawumbi akunakwenzeka" ukuzidala zisebenzisa imveliso eqhelekileyo. Kuvavanyo lweelebhu, iqela lisebenzise iimodeli eziprintiweyo ze-3D zee-gyroids, zandisa amawaka amaxesha ubukhulu bendalo.
Iqela lifake iimodeli ze-3D kwiimvavanyo ezahlukeneyo zovavanyo kunye noxinzelelo, zisebenzisa iimodeli zazo ukubonisa impendulo yoomatshini phantsi komthwalo. Kwenye yeesampulu zethu bayifumana nge I-5% yensimbi yengxinano efunyenwe izihlandlo ezili-10 ukomelela kwezi zinto zithethiweyo«.
Imathiriyeli ye-3D yegraphene, eyenziwe yindawo egobileyo phantsi kwe-deformation, iphendula njengamaphepha. Eli phepha linokushwabana ngokulula, kuba alomelelanga kububanzi nobude balo. Kodwa xa iphepha liqengqelwe kwityhubhu, amandla kunye nobude betyhubhu mkhulu kakhulu. Ukucwangciswa kwejiyometri kweeflaphene flakes emva konyango kunokucwangciswa okufanayo.
Izicelo ezinokwenzeka
Phakathi kwezicelo ezinokubakho, kuyacaca ukuba Iimpawu zejiyometri ezifunyenwe kunye nezinye izinto zinokusetyenziswa, ezinjengeepolymers okanye isinyithi, ukwenzela ukuba fumana amandla afanayo ngexabiso eliphantsi lemveliso. Kukwakho nethuba lokusebenzisa iipolymer okanye amasuntswana esinyithi njengeetemplate, kusetyenziswa indawo yokugcina umphunga wamachiza ngaphambi kobushushu kunye noxinzelelo kunyango ukuwamboza ngegraphene. Emva koko, ipolymer okanye isinyithi sinokususwa ukuze kugcinwe i-3D graphene kwifom ye-gyroid. Le geometry yokungena inokusetyenziswa xa kusakhiwa izakhiwo ezinkulu, Njengebhulorho. Inokude ibonelele ngokugquma kakuhle kwebhulorho, ngenxa yemali yendawo evaliweyo.
