I-Carbon fiber inezimpawu zamandla aphezulu nesisindo esikhanyayo, kanye nezinto ezihlanganisiwe nge-polymer zilungele kakhulu i-aerospace, imboni yezimoto, ama-turbine ama-turbine kanye nempahla yezemidlalo. Kodwa-ke, lezo zinto ezinhlanganisela ezinjalo zizokwehluleka ngokwedlulele ngaphandle kwesixwayiso, ezifana nokuwa kwama-ceramics.

Muva nje, abacwaningi abavela kwelebhu ye-Oak Ridge National Laboratory neVirginia University bathuthukisa inqubo futhi bayishicilela kwiphephabhuku lezinhlanganisela zesayensi nobuchwepheshe. Ngokumane ungeze i-nano-tio2, kunganikeza isixwayiso sokuqala sokulahlekelwa ukusebenza kahle.

Izinto ze-Carbon fiber composite, ikakhulukazi izinto ezihlanganisiwe ezisuselwa ku-epoxy resin, zithambekele ekuhlelekeni lapho isibopho phakathi kwe-fiber ne-matrix sehluleka. Uma kungekho noma yiziphi izimpawu zesexwayiso zangaphandle, ukuqhekeka okungazelelwe kungenzeka, okuvimbela usizo kwalezi zinto ezihlanganisiwe kuzinhlelo zokusebenza zesakhiwo. Abantu bahlola izindlela ezahlukahlukene zokuqapha ubuqotho bezinhlekelele ze-carbon fiber composites, njengokufaka izinto zokufaka ama-piezoresive ezintweni ezibonakalayo, okushintsha ukumelana nosizi. Izinto zePiezoresurive zingaguqula ubunzima obusebenza emishini zibe amasiginali kagesi, angatholwa izinzwa zokubheka impilo yesakhiwo sezinto ezihlanganisiwe.

Abaphenyi bashumeka i-Tio2Nano titanium dioxideAma-nanoparticles ku-polymer coating noma ukulinganisa imicu ye-carbon ukwenza izinto ze-piezoresustive zisatshalaliswe ngokufanayo kuzo zonke izinto ezihlanganisiwe. Ukulinganisa kuvame ukusetshenziselwa i-carbonised carbon fiber, ukuze kube lula ukucubungula futhi kusetshenziswe futhi kuhlanganiswe ne-matrix, bese ekugcineni usungule ikhono lokuzwakala ubunzima kule nqubo. Lapho ingcindezi iqedwa, ukumelana kungu-zero, futhi lapho ingcindezi yenziwa, ukukhuphuka kwayo. Kuliqiniso, inani le-Tio2 Nanoparticles Engeziwe Izidingo ezizolawulwa, ziphezulu kakhulu ingxenye ezokwehlisa amandla ezinto ezibonakalayo, futhi ukungezwa kahle kuzothuthukisa ukusebenza okude (ukumuncwa kwethukile kanye nokusebenza kwama-buffering) kwezinto ezibonakalayo.

Inkampani yaseHongwe Yayinikela i-Nano Titanium dioxide kanje:

1. I-Anatase Tio2, usayizi 10nm, 30-50nm. 99% +

2. URutile Tio2, usayizi 10nm, 30-50nm, 100-200nm. 99% +

Sicela uzizwe ukhululekile ukuxhumana nathi nganoma yimiphi imibuzo.
