Iyini i-carbon fiber eqoshiwe?

I-carbon fiber eqoshiwe i-carbon fiber enqanyuliwe. Lapha i-carbon fiber ingushintsho lwe-morphological kuphela, isuka ku-carbon fiber filament ibe i-filament emfushane, kodwa ukusebenza kwe-short-cut carbon fiber ngokwayo akukashintshi. Ngakho kungani ufuna ukusika i-filament enhle ibe mfushane?
Okokuqala, kufanele siqale inqubo yokubumba yezinto ezihlanganisiwe. Ngokuvamile i-carbon fiber filament izolukwa ibe yindwangu ye-carbon fiber noma yenziwe ibe yi-carbon fiber prepreg, bese ngokusebenzisainqubo yokubumba, i-RTM, i-vacuum bagging, amathini okucindezela ashisayo nezinye izinquboibe yimikhiqizo ehlanganisiwe ye-carbon fibre composite. Yiqiniso, kukhona nezinye izinqubo zokubumba ezingadingi izinto eziphakathi, ngokuqondile nge-carbon filament filament yokubunjwa, njengokubumba kwe-pultrusion, ukugoqa ukugoqa nokunye.
I-Carbon fiber elukiwe ibe yindwangu ye-carbon fibre noma eyenziwe yaba yi-prepreg, hamba uyokwenza imikhiqizo, kunobubi bemvelo, akulungile ukunamathela isikhunta. Ukuba khona kwesikhunta ukunikeza isimo sezinto ezihlanganisiwe, isikhunta sinohlobo olunjani lokuma, into yokugcina eyinhlanganisela nayo inaluphi uhlobo lokuma. Kodwa-ke, uma indwangu ye-carbon fibre noma i-prepreg ingalingani kahle nesikhunta, ukwakheka kwezinto eziyinhlanganisela akufani nokuma kwesikhunta. Ukwengeza, kwamanye amakhona, indwangu ye-carbon fiber kulula ukuyifaka ibhuloho, yakha umgodi wendawo, okugcina kubangela ukwehla kokusebenza kwemikhiqizo ehlanganisiwe ye-carbon fiber.
I-carbon fiber filament ngaphakathi kwendwangu ye-carbon fiber noma i-prepreg iboshiwe futhi akulula ukuyihambisa. Ikakhulukazi esimweni sokucindezela, ukuhamba kwe-resin ne-carbon fiber filament kubi kakhulu, okuzogcina kubangele ubunzima bokubumba noma ukuwohloka kokusebenza.
Ubude bufushane, bungcono ubumanzi be-i-carbon fiber eqoshiwe. Kufanele kwaziwe ukuthi ukubumba umjovo kuwubuchwepheshe obusetshenziswa kakhulu futhi obuvuthiwe kunqubo yokubumba ipulasitiki. Uma isetshenziswa ekukhiqizeni izinto ezihlanganisiwe, kuyoba ushintsho olukhulu.
Kodwa-ke, ubude be-short-cut carbon fiber abukwazi ukuncishiswa, ngoba ubude obufushane be-carbon fiber enqamulelayo, i-resin ne-carbon fiber bonding izoba buthakathaka. Ngenxa yokuthi isibopho phakathi kwe-resin ne-carbon fiber ilingana ngokuqondile nendawo yokuxhumana phakathi kwabo, uma ubude bufinyeziwe, khona-ke indawo yokuxhumana iyancishiswa nakanjani.
Khona-ke kukhona ukuphikisana lapha, okungukuthi, ukuphikisana phakathi kokusebenza kwe-fiber-cut short kanye nokuhamba. Uma ubude befayibha bude, mancane amathuba okuthi zihlakazeke, ifayibha kanye nefayibha kulula ukuhlanganisa, kodwa uma inhlanganisela yefiber neresin iqina, ukusebenza kwempahla eyinhlanganisela kuzoba phezulu. Lapho ubude be-fiber bufushane, kuba lula ukuhlakazeka, ngokugeleza okuhle, kodwa isibopho se-fiber ne-resin sibuthakathaka kancane. Indlela yokulinganisa lokhu kungqubuzana, kudingeka kufundwe, ngokuvamile, ukwenza i-short-cut carbon fiber reinforced plastic pellets, ubude be-1-9mm ububanzi.
Kukhona futhi indlela yokuthuthukisa amandla okubopha phakathi kwe-carbon fiber ne-resin, okuyi-ejenti yokulinganisa. Ngokuvamile, kukhona i-ejenti yokulinganisa phezu kwendawoi-carbon fiberifektri, esetshenziselwa ukuvikela i-carbon fiber ekufakweni ohlelweni lokupakisha, ukudlulisa nokusebenza, futhi ngakolunye uhlangothi, isetshenziselwa ukuhlanganisa i-carbon fiber kanye ne-resin, futhi idlale indima yokuthuthukisa amandla okubopha.
Kodwa-ke, le ejenti yokulinganisa ngokuyisisekelo ingeye-thermosetting resin. Iningi lama-resin asetshenziselwa ukwenza ama-pellets angama-thermoplastic resins, ngakho-ke i-ejenti yokulinganisa kufanele ilungiswe kabusha. Enye iwukushisa i-ejenti yokulinganisa yasekuqaleni futhi wenze isendlalelo esisha se-ejenti yokulinganisa. Enye iwukushisa i-ejenti yokulinganisa yasekuqaleni futhi wenze isendlalelo esisha se-ejenti yokulinganisa; enye iwukuba i-ejenti yokulinganisa futhi ngesisekelo se-ejenti yokulinganisa yasekuqaleni, ebizwa ngokuthi ukulinganisa okwesibili.
Ngaphezu kokwenza ama-granules okubumba umjovo,i-carbon fiber eqoshiweinezinye izinto ezisetshenziswayo, njengezenziwe nge-carbon fibre mat, noma ezenziwe ngephepha le-carbon fibre. Ubude obudingekayo be-carbon fiber eqoshiwe buzoba yinde kunobude be-fiber eqoshiwe yama-granules.
Ngaphezu kwalokho, ngaphezu kwezinhlayiya zekhabhoni eziqoshwe ngokunganaki, kukhona nemicu yekhabhoni eqotshiwe ehlanganisiwe. Le fibre enqamulelayo isendleleni enqamulelayo ngaphambi kwe-carbon fibre tow yohlobo oluthile olunqunywe kusengaphambili, bese inqanyulwa ku-short-cut fiber inezici zenqwaba, equkethe inani le-resin izoba ngaphezulu kakhulu kuneminye i-short-cut fiber.
