Carbon fiber e na le litšobotsi tsa matla a phahameng le boima bo bobebe, 'me thepa e kopantsoeng e nang le polymer e loketse haholo bakeng sa sefofane, indasteri ea likoloi, li-blades tsa moea le thepa ea lipapali.Leha ho le joalo, lisebelisoa tse joalo tse entsoeng ka motsoako li tla hlōleha ka mokhoa o kotsi ntle le temoso, ho tšoana le ho oa ha lirafshoa.

Haufinyane tjena, bafuputsi ba Oak Ridge National Laboratory le Virginia Tech le State University ba ile ba qapa mokhoa 'me ba o phatlalatsa ho Journal of Composites Science and Technology.Ka ho kenyelletsa nano-TiO2 feela, e ka fana ka temoso ea pele ea ho lahleheloa ke katleho.

Lisebelisoa tsa motsoako oa carbon fiber, haholo-holo lisebelisoa tse entsoeng ka motsoako o thehiloeng ho epoxy resin, li atisa ho senyeha ha maqhama pakeng tsa fiber le matrix a hlōleha.Ha ho se na matšoao leha e le afe a lemosang a ka ntle, ho ka 'na ha robeha ka tšohanyetso, e leng se fokotsang molemo oa lisebelisoa tsena tse nang le likarolo tse ngata ha ho etsoa moralo.Batho ba ntse ba hlahloba mekhoa e fapaneng ea ho lekola bots'epehi ba sebopeho sa li-composites tsa carbon fiber, joalo ka ho kenya lisebelisoa tsa piezoresistive ka har'a thepa, e fetolang khanyetso ka khatello.Lisebelisoa tsa piezoresistive li ka fetola khatello ea mochini hore e be lipontšo tsa motlakase, tse ka bonoang ke li-sensor ho lekola bophelo bo botle ba sebopeho sa lisebelisoa tse kopaneng.

Bafuputsi ba kentse TiO2Nano titanium dioxidenanoparticles ka har'a polymer kapa boholo ba likhoele tsa khabone ho etsa hore thepa ea piezoresistive e ajoe ka mokhoa o ts'oanang ho thepa e kopaneng.Sizing hangata e sebelisoa bakeng sa fiber ea carbonized carbon, e le hore e be bonolo ho e sebetsa le ho e sebelisa le ho kopana le matrix, 'me qetellong ho thehoe bokhoni ba ho utloa khatello ea kelello ts'ebetsong ena.Ha khatello e felisoa, ho hanyetsa ke zero, 'me ha khatello e hlahisoa, ho hanyetsa hoa eketseha.Ha e le hantle, palo ea li-nanoparticles tsa TiO2 tse kenyelletsoeng li hloka ho laoloa, karolo e phahameng haholo e tla fokotsa matla a thepa e kopantsoeng, 'me ho eketsoa ka mokhoa o nepahetseng ho tla ntlafatsa ts'ebetso ea damping (ho ts'oaroa ha ts'oaetso le ts'ebetso ea buffering) ea thepa.

Khamphani ea Hongwu e fana ka Nano titanium dioxide ka tsela e latelang:
