Iqhaza lobuchwepheshe be-nanotube ethangi le-carbon fiber: izinzuzo zangempela noma i-hype nje?

Ukuqalisa

Ubuchwepheshe be-nanotube kube yisihloko esishisayo kwisayensi ethuthukisiwe yesayensi, kanti izimangalo lapho ama-carbon nanotubes (CNTs) angathuthukisa kakhulu amandla, ukuqina, kanye nokwenza umsebenziIthangi le-carbon fibers. Kodwa-ke, izinhlelo zokusebenza ezisebenzayo zivame ukukhombisa imiphumela exubile. Abanye abakhiqizi babika ukwanda kwezakhiwo zemishini, kanti ezinye, njengokuhlolwa kwakho kwelebhu, khombisa okuncane ukuthi akukho ngcono. Le ndatshana ihlola ukuthi ubuchwepheshe be-nanotube bufaka isandla kangcono ngempelaIthangi le-carbon fibers noma uma kuyi-hype nje yokuthengisa.

Ukuqonda ubuchwepheshe be-carbon nanotube

Ama-carbon nanotubes angama-molecule we-cylindrical aqukethe amashidi asongwe ama-athomu wekhabhoni elilodwa (i-grapheene). Bayaziwa ngamandla abo ahlukile, aphezulu kagesi nokwenziwa okushisayo, kanye nezakhiwo ezingasindi. Emthiyori, lapho ama-CNTs afakwa kwikhambi le-carbon fiber, angakhulisa amandla ashubile, athuthukise ukumelana nomthelela, futhi anwebe isikhathi sokuphila komkhiqizo wokugcina.

Ukuhlanganiswa kwama-nanotubes kanjaniIthangi le-carbon fibers

I-Nanotubes ingangezwa ku-resin matrix noma ngqo kwinqubo yokukhiqiza ye-carbon fiber. Umgomo ukudala ukwakheka okuqiniswe ngokwengeziwe ngokwenza ngcono ukubopha izibopho phakathi kwe-resin kanye ne-carbon fibers. Ezinye izinzuzo ezilindelwe zifaka:

• Ukwanda kwamandla ashukumisayo: Ama-nanotubes aqine kakhulu, futhi uma ahlakazeke kahle, kufanele athuthukise amandla aphelele wenhlanganisela.
• Ukuqina okuthuthukile: Ama-CNTs kulindeleke ukuthi anciphise ukungcola, okwenza ithangi limelane nokukhathala kanye nemijikelezo yengcindezi.
• Ukwehliswa kwesisindo: Ngokwenza ngcono amandla ezibonakalayo, amathangi acwebezelayo futhi akhanyayo angenziwa ngaphandle kokuyekethisa ukusebenza.
• Ukuqina okuthuthukile okushisayo: Ama-nanotubes anokumelana okuhle kakhulu kokushisa, okungasiza ekusetshenzisweni kwezinga lokushisa okuphezulu.

Kungani ezinye izivivinyo zibonisa okuncane ukungathuthuki

Naphezu kwalezi zinzuzo zethiyori, amalebhu amaningi nabakhiqizi - kufaka phakathi inzuzo yakho encane ebonakalayo ebonakalayo. Ezinye izizathu zalokhu zifaka:

1. Ukuhlakazeka okumpofu kwama-nanotubes
   • Ama-CNTs athambekele ekuhlanganiseni ndawonye, ​​okwenza kube nzima ukuwazisa ngokulinganayo e-resin. Uma ukuhlakazwa kungafani, izinzuzo ezilindelwe ezilindelwe zingahle zingasebenzi.
2. Izinkinga Zokubopha Ngezingcingo
   • Mane nje ungeze ama-nanotubes ku-resin noma i-fiber akuqinisekisi adhesion angcono. Uma isibopho phakathi kwama-CNTs kanye nezinto ezizungezile zibuthakathaka, azinasandla emandleni enhlaka.
3. Ukucubungula Izinselelo
   • Ukungezwa kwama-CNTs kungashintsha ukubonwa kwama-resins, okwenza inqubo yokukhiqiza ibe yinkimbinkimbi kakhulu futhi ibe nokunciphisa ikhwalithi yomkhiqizo wokugcina.
4. I-Marginal GAINS VS. Izindleko eziphakeme
   • Ngisho noma okunye ukuthuthukiswa kubhekwa, kungenzeka kungabalulekanga ngokwanele ukuzithethelela izindleko ezingeziwe nobunzima bokuhlanganisa ama-CNTsIthangi le-carbon fiberukukhiqiza.

Izicelo zangempela zomhlaba: lapho kungasebenza khona

Yize ama-CNTs kungenzeka angakhuliseki ngokwesikoIthangi le-carbon fiberIsetshenziswa eSCBA, eebd, noma izibhamu zomoya, basengase bebengaba nezicelo ze-niche:

• Izimo EziningiE-Aerospace kanye nasezisetshenzisweni zamasosha, ngisho nokuthuthuka okuncane ngamandla noma ukuncishiswa kwesisindo kungavumela ukusetshenziswa kwamathangi athuthukisiwe we-CNT.
• Ukuphikiswa Kokukhathala Okuphezulu: Uma kuhlanganiswe kahle, ama-CNTs anganciphisa ukugoqa, okungasizakala izimboni lapho amathangi athola khona imijikelezo ebeka phambili.
• I-future Research Engamandla: Njengoba amasu wokuhlakazeka nobuchwepheshe bobusuku bathuthukisa, ukusetshenziswa kwekusasa kwama-CNS ku-Carbon fiber Composites angathela imiphumela engcono.

Isiphetho: hype noma iqiniso?

Kususelwa kokutholakele kwamanje, ama-CNTs anamandla kodwa awakabi ngumguquki womdlalo weIthangi le-carbon fibers ezisetshenziselwa iningi lezimboni. Izinselelo zokuhlakazwa, ukubopha izibopho kanye nokusebenza kwezindleko zizenza zingenzeki abakhiqizi abaningi. Ngenkathi ucwaningo oluqhubekayo lungagcina luvule amandla abo aphelele, okwamanje, ubuchwepheshe be-nanotube kuIthangi le-carbon fiberAma-S abonakala ekhona ngokuthuthuka kokuhlola kunokuba abe nesici esinawo. Uma izivivinyo zakho zikhombisa inzuzo encane, kungahle kube ngcono kakhulu ukugxila ezindleleni ezifakazelwe ngokwengeziwe zokwenza ngcono ukusebenza kwamathangi esikhundleni sokutshala imali kakhulu ekuhlanganiseni kwe-CNT.
