Ifayibha yeCarbon ineempawu zamandla aphakamileyo kunye nobunzima obulula, kwaye izinto ezihlanganisiweyo ezinepolymer zifanelekile kakhulu kwi-aerospace, imboni yeemoto, i-wind turbine blades kunye nempahla yezemidlalo.Nangona kunjalo, izinto ezinjalo ezidibeneyo ziya kusilela ngokukhawuleza ngaphandle kwesilumkiso, kufana nokuwa kweekeramics.

Kutshanje, abaphandi abavela kwiLabhoratri yeSizwe ye-Oak Ridge kunye neVirginia Tech kunye neYunivesithi yeSizwe baphuhlise ubuchule kwaye bayipapasha kwiJenali yeComposites Science and Technology.Ngokudibanisa nje i-nano-TiO2, inokubonelela ngesilumkiso sangethuba sokuphulukana nokusebenza.

Izixhobo zekhabhoni zefiber composite, ngakumbi izinto ezidityanisiweyo ezisekwe kwi-epoxy resin, zithambekele ekubeni i-delamination xa ibhondi phakathi kwefiber kunye ne-matrix isilela.Xa kungekho naziphi na iimpawu ezilumkisayo zangaphandle, ukuphuka ngesiquphe kunokuthi kwenzeke, nto leyo ethintela ukusetyenziswa kwezi zixhobo zidibeneyo kwizicelo zesakhiwo.Abantu baphonononga iindlela ezahlukeneyo zokubeka iliso kwingqibelelo yesakhiwo se-carbon fiber composites, njengokufakela izixhobo ze-piezoresistive kwizinto eziphathekayo, ezitshintsha ukuxhathisa kunye noxinzelelo.Izinto ze-piezoresistive ziyakwazi ukuguqula ukunyanzeliswa komatshini kwiimpawu zombane, ezinokuthi zichongwe ngamava okuqonda ukujonga impilo yesakhiwo sezinto ezidibeneyo.

Abaphandi bafakela i-TiO2Nano titanium dioxideI-nanoparticles kwi-polymer coating okanye ukulinganisa kwe-carbon fibers ukwenza imathiriyeli ye-piezoresistive isasazwe ngokufanayo kuyo yonke into edibeneyo.Ubungakanani budla ngokusetyenziselwa i-carbonized fiber fiber, ukwenzela ukuba kube lula ukusetyenzwa kunye nokusetyenziswa kunye nokudibanisa kunye ne-matrix, kwaye ekugqibeleni kusekwe ukukwazi ukuva ubunzima kule nkqubo.Xa uxinzelelo luphelile, ukuchasana ku-zero, kwaye xa uxinzelelo lwenziwa, ukuchasana kuyanda.Ngokuqinisekileyo, inani le-nanoparticles ye-TiO2 eyongeziweyo kufuneka ilawulwe, umlinganiselo ophezulu kakhulu uya kunciphisa amandla ezinto ezidibeneyo, kwaye ukongezwa okufanelekileyo kuya kuphucula ukusebenza kokudambisa (ukutshatyalaliswa kwe-shock kunye nokusebenza kwe-buffering) yezinto eziphathekayo.

Inkampani yaseHongwu ibonelela ngeNano titanium dioxide ngolu hlobo lulandelayo:

1. Anatase TiO2, ubukhulu 10nm, 30-50nm.99%+

2. I-Rutile TIO2, ubukhulu be-10nm, 30-50nm, 100-200nm.99%+

Nceda uzive ukhululekile ukuqhagamshelana nathi ngayo nayiphi na imibuzo.
