Kule mihla yokuqhubela phambili kwezobuchwepheshe ngokukhawuleza, ii-carbon fiber composites zizenzela igama kwiindawo ezahlukeneyo ngenxa yokusebenza kwazo okuphezulu. Ukususela kwizicelo eziphezulu kwi-aerospace ukuya kwiimfuno zemihla ngemihla zezinto zemidlalo, ii-carbon fiber composites zibonakalise amandla amakhulu. Nangona kunjalo, ukulungiselela ii-carbon fiber composites ezisebenzayo, unyango lokuvuselelaiifayibha zekhabhonilinyathelo elibalulekileyo.
Umfanekiso we-electron microscope yomphezulu we-carbon fiber
I-carbon fiber, into esebenza kakhulu kwi-fiber, ineempawu ezininzi ezinomtsalane. Iquka ikakhulu i-carbon kwaye inesakhiwo esinde se-filamentary. Ngokwembono yesakhiwo somphezulu, umphezulu we-carbon fiber uthambile kwaye unamaqela ambalwa asebenzayo. Oku kungenxa yokuba ngexesha lokulungiselela i-carbon fibers, i-carbonization yobushushu obuphezulu kunye nezinye iindlela zonyango zenza umphezulu we-carbon fibers ube kwimeko engasebenziyo. Le propati yomphezulu izisa uthotho lwemingeni ekulungiseleleni i-carbon fiber composites.
Umphezulu ogudileyo wenza ukuba unxibelelwano phakathi kwe-carbon fiber kunye nezinto ze-matrix lube buthathaka. Xa kulungiswa izinto ezidityanisiweyo, kunzima ukuba izinto ze-matrix zenze unxibelelwano oluqinileyo kumphezulu we-ifayibha yekhabhoni, nto leyo echaphazela ukusebenza ngokubanzi kwezinto ezidityanisiweyo. Okwesibini, ukungabikho kwamaqela asebenzayo asebenzayo kuthintela impendulo yamakhemikhali phakathi kweefayibha zekhabhoni kunye nezinto zematrix. Oku kwenza ukuba ukudibana phakathi kwezi zimbini kuxhomekeke kakhulu kwimiphumo yomzimba, efana nokubethelwa koomatshini, njl.njl., okudla ngokungazinzi ngokwaneleyo kwaye kulungele ukwahlukana xa kuthotyelwa ngamandla angaphandle.
Umzobo wesicwangciso sokuqiniswa kwelaphu le-carbon fiber phakathi kweengqimba ngeetyhubhu ze-carbon nanotubes
Ukuze kusonjululwe ezi ngxaki, unyango lokuvuselela iifayibha zekhabhoni luyafuneka.iifayibha zekhabhonibonisa utshintsho olukhulu kwiinkalo ezininzi.
Unyango lokuvuselela lunyusa uburhabaxa bomphezulu weefayibha zekhabhoni. Ngokusebenzisa i-oxidation yamakhemikhali, unyango lwe-plasma kunye nezinye iindlela, imingxunya emincinci kunye nemingxunya inokukrolwa kumphezulu weefayibha zekhabhoni, okwenza umphezulu ube rhabaxa. Lo mphezulu urhabaxa unyusa indawo yoqhagamshelwano phakathi kwefayibha yekhabhoni kunye nezinto ezisetyenziswa kwisiseko, nto leyo ephucula uqhagamshelo loomatshini phakathi kwezi zimbini. Xa izinto ze-matrix zibotshelelwe kwifayibha yekhabhoni, zikwazi ngcono ukuzifaka kwezi zakhiwo zirhabaxa, zenze uqhagamshelo oluqinileyo.
Unyango lokuvuselela lunokungenisa ubuninzi bamaqela asebenzayo asabelayo kumphezulu we-carbon fiber. La maqela asebenzayo anokusabela ngokwekhemikhali namaqela asebenzayo ahambelanayo kwizinto ze-matrix ukuze enze iibhondi zeekhemikhali. Umzekelo, unyango lwe-oxidation lunokungenisa amaqela e-hydroxyl, amaqela e-carboxyl kunye namanye amaqela asebenzayo kumphezulu wee-carbon fibers, anokusabela ngei-epoxyamaqela kwi-resin matrix njl.njl. ukwenza ii-covalent bonds. Amandla ale khemikhali bonding aphezulu kakhulu kunalawo okubopha ngokwasemzimbeni, nto leyo ephucula kakhulu amandla okubopha phakathi kwe-carbon fiber kunye nezinto ze-matrix.
Amandla omphezulu we-activated carbon fiber nawo ayanda kakhulu. Ukwanda kwamandla omphezulu kwenza kube lula ukuba i-carbon fiber imanziswe zizinto ze-matrix, ngaloo ndlela kube lula ukusasazeka nokungena kwezinto ze-matrix kumphezulu we-carbon fiber. Kwinkqubo yokulungiselela izinto ezidityanisiweyo, izinto ze-matrix zinokusasazwa ngokulinganayo zijikeleze ii-carbon fibers ukuze zenze isakhiwo esixineneyo. Oku akuphuculi nje kuphela iimpawu zoomatshini zezinto ezidityanisiweyo, kodwa kukwaphucula nezinye iimpawu zayo, ezinje ngokumelana nokugqwala kunye nokuzinza kobushushu.
Iifayibha zekhabhoni ezisebenzayo zinezibonelelo ezininzi zokulungiselela ii-composites zekhabhoni.
Ngokuphathelele iipropati zoomatshini, amandla okubopha phakathi kwe-activatediifayibha zekhabhonikwaye izinto ze-matrix ziphuculwe kakhulu, nto leyo evumela ukuba ezi composites zikwazi ukudlulisa uxinzelelo olungcono xa ziphantsi kwamandla angaphandle. Oku kuthetha ukuba iimpawu zoomatshini zezinto ezidibeneyo ezifana namandla kunye ne-modulus ziphuculwe kakhulu. Umzekelo, kwicandelo leenqwelo-moya, elifuna iimpawu zoomatshini eziphezulu kakhulu, iindawo zeenqwelo-moya ezenziwe ngee-activated carbon fiber composites ziyakwazi ukumelana nemithwalo emikhulu yokubhabha kwaye ziphucule ukhuseleko kunye nokuthembeka kwenqwelo-moya. Kwicandelo leempahla zemidlalo, ezifana neefreyimu zebhayisekile, iiklabhu zegalufa, njl.njl., ii-activated carbon fiber composites zinokubonelela ngamandla angcono kunye nokuqina, ngelixa zinciphisa ubunzima kwaye ziphucula amava abadlali.
Ngokuphathelele ukumelana nokugqwala, ngenxa yokungeniswa kwamaqela asebenzayo asebenzayo kumphezulu weefayibha zekhabhoni ezisebenzayo, la maqela asebenzayo anokwenza ukubopha kweekhemikhali okuzinzileyo ngakumbi nezinto ze-matrix, ngaloo ndlela kuphucula ukumelana nokugqwala kwezinto ezidityanisiweyo. Kwezinye iimeko ezinzima zokusingqongileyo, ezifana nokusingqongileyo kolwandle, ishishini leekhemikhali, njl.njl., i-activatedii-composites ze-carbon fiberingakwazi ukumelana ngcono nokonakala kwezinto ezibangela ukubola kwaye yandise ubomi benkonzo. Oku kubaluleke kakhulu kwezinye izixhobo kunye nezakhiwo ezisetyenziswa kwiindawo ezinzima ixesha elide.
Ngokuphathelele uzinzo lobushushu, ukubopha okuhle phakathi kwe-activated carbon fiber kunye nezinto ze-matrix kunokuphucula uzinzo lobushushu lwee-composites. Phantsi kobushushu obuphezulu, ii-composites zinokugcina iipropati ezingcono zoomatshini kunye nozinzo olulinganayo, kwaye azinakwenzeka kangako ukuba ziguqulwe kwaye zonakale. Oku kwenza ukuba ii-activated carbon fiber composites zibe namathuba amaninzi okusetyenziswa kwizicelo zobushushu obuphezulu, njengeenxalenye zenjini yeemoto kunye neenxalenye ze-hot end zenjini yeenqwelo moya.
Ngokuphathelele ukusebenza kokucubungula, iifayibha zekhabhoni ezisebenzayo zinomsebenzi omninzi womphezulu kwaye zihambelana ngcono nezinto ze-matrix. Oku kwenza kube lula ukuba izinto ze-matrix zingene kwaye zinyangeke kumphezulu wefayibha yekhabhoni ngexesha lokulungiselela izinto ezidityanisiweyo, ngaloo ndlela ziphucula ukusebenza kakuhle kokucubungula kunye nomgangatho wemveliso. Kwangaxeshanye, uyilo lwee-composites ze-carbon fiber ezisebenzayo nalo luyaphuculwa, nto leyo evumela ukuba zenziwe ngokwezifiso kwiizicelo ezahlukeneyo kwaye zihlangabezane neemfuno ezahlukeneyo zobunjineli ezintsonkothileyo.
Ke ngoko, unyango lokuvuselelaiifayibha zekhabhonilikhonkco eliphambili ekulungiseleleni ii-composites ze-carbon fiber ezisebenza kakuhle. Ngokusebenzisa unyango lokuvuselela, ulwakhiwo lomphezulu we-carbon fiber lunokuphuculwa ukuze kwandiswe uburhabaxa bomphezulu, kungeniswe amaqela asebenzayo, kwaye kuphuculwe amandla omphezulu, ukuze kuphuculwe amandla okudibanisa phakathi kwe-carbon fiber kunye nezinto ze-matrix, kwaye kubekwe isiseko sokulungiselela ii-composites ze-carbon fiber ezineempawu ezintle zoomatshini, ukumelana nokugqwala, uzinzo lobushushu kunye nokusebenza kokucubungula. Ngenkqubela phambili eqhubekayo yesayensi kunye netekhnoloji, kukholelwa ukuba itekhnoloji yokuvuselela i-carbon fiber iya kuqhubeka nokuvelisa nokuphuhlisa, inika inkxaso enamandla yokusetyenziswa ngokubanzi kwee-composites ze-carbon fiber.
