Iyini i-carbon fiber eqoshiwe?

I-carbon fiber eqoshiwe iyi-carbon fiber enqanyulwa. Lapha i-carbon fiber iwushintsho nje lokwakheka, kusukela ku-carbon fiber filament kuya ku-short filament, kodwa ukusebenza kwe-short-cut carbon fiber ngokwayo akukashintshi. Pho kungani ufuna ukusika i-filament short enhle?
Okokuqala, kufanele siqale enkambisweni yokubumba izinto ezihlanganisiwe. Ngokuvamile i-carbon fiber filament kufanele ilukwe ibe yindwangu ye-carbon fiber noma yenziwe ibe yi-carbon fiber prepreg, bese idlulainqubo yokubumba, i-RTM, ukufaka izikhwama ze-vacuum, amathini okucindezela ashisayo nezinye izinqubozibe yimikhiqizo eyahlukahlukene ye-carbon fiber composite. Yiqiniso, kunezinye izinqubo zokubumba ezingadingi izinto eziphakathi nendawo, ngqo nge-carbon fiber filament ukuze kubumbanwe, njengokubumba kwe-pultrusion, ukubumba okugoqekayo njalo njalo.
I-carbon fiber elukiwe ibe yindwangu ye-carbon fiber noma yenziwe ibe yi-prepreg, uma kwenziwa imikhiqizo, kukhona ukungahleleki kwemvelo, akukuhle ukunamathela isikhunta. Ukuba khona kwesikhunta ukunikeza ukuma kwezinto ezihlanganisiwe, isikhunta sinohlobo luni lwesimo, izinto zokugcina ezihlanganisiwe nazo zinohlobo luni lwesimo. Kodwa-ke, uma indwangu ye-carbon fiber noma i-prepreg ingalingani kahle nesikhunta, ukuma kwezinto ezihlanganisiwe akuhambisani nesimo sesikhunta. Ngaphezu kwalokho, kwamanye amakhona, indwangu ye-carbon fiber kulula ukuyihlanganisa, yakha umgodi wendawo, okugcina kubangele ukwehla kokusebenza kwemikhiqizo ehlanganisiwe ye-carbon fiber.
I-filament ye-carbon fiber engaphakathi kwendwangu ye-carbon fiber noma i-prepreg iboshiwe futhi akulula ukuyihambisa. Ikakhulukazi uma kunengcindezi, ukuhamba kwe-resin kanye ne-carbon fiber filament kubi kakhulu, okuzogcina kubangele ubunzima bokubumba noma ukwehla kokusebenza.
Uma ubude bufushane, kulapho ukugeleza kwe-i-carbon fiber eqoshiweKufanele kwaziwe ukuthi ukubumba ngomjovo ubuchwepheshe obusetshenziswa kakhulu futhi obuvuthiwe enqubweni yokubumba ngepulasitiki. Uma kusetshenziswa ekukhiqizweni kwezinto ezihlanganisiwe, kuzoba ushintsho olukhulu.
Kodwa-ke, ubude be-carbon fiber emfushane abunakwehliswa, ngoba uma ubude be-carbon fiber emfushane bufushane, ukubopha kwe-resin ne-carbon fiber kuzoba buthakathaka. Ngenxa yokuthi ukubopha phakathi kwe-resin ne-carbon fiber kuhambelana ngqo nendawo yokuxhumana phakathi kwazo, uma ubude bufushane, khona-ke indawo yokuxhumana iyancipha nakanjani.
Bese kuba khona ukuphikisana lapha, okungukuthi, ukuphikisana phakathi kokusebenza kwefayibha emfushane kanye nokuhamba. Uma ubude befayibha bude, kulapho kulula khona ukuhlakazeka, ifayibha kanye nefayibha kulula ukufitha, kodwa uma inhlanganisela yefayibha kanye ne-resin iqina, ukusebenza kwezinto ezihlanganisiwe kuzoba phezulu. Uma ubude befayibha bufushane, kulula ukuhlakazeka, ngokuhamba kahle, kodwa isibopho sefayibha kanye ne-resin sibuthakathaka kancane. Indlela yokulinganisela lokhu kuphikisana, kudingeka ifundwe, ngokuvamile, ukwenza ama-pellet epulasitiki aqiniswe ngefayibha emfushane ye-carbon, ubude bungu-1-9mm.
Kukhona futhi indlela yokuthuthukisa amandla okubopha phakathi kwe-carbon fiber ne-resin, okuyi-ejenti yokulinganisa. Ngokuvamile, kuba ne-ejenti yokulinganisa ebusweni be-i-carbon fiberifektri, esetshenziselwa ukuvikela i-carbon fiber ekuqhekekeni enqubweni yokupakisha, ukudlulisa nokusebenza, kanti ngakolunye uhlangothi, isetshenziselwa ukuhlanganisa i-carbon fiber kanye ne-resin, futhi idlale indima yokuthuthukisa amandla okubopha.
Kodwa-ke, le agent yokulinganisa ngokuyinhloko yenzelwe i-thermosetting resin. Iningi lama-resin asetshenziselwa ukwenza ama-pellets ama-resin e-thermoplastic, ngakho-ke i-agent yokulinganisa kumele ilungiswe. Enye ukushisa i-agent yokulinganisa yokuqala bese wenza ungqimba olusha lwe-agent yokulinganisa. Enye ukushisa i-agent yokulinganisa yokuqala bese wenza ungqimba olusha lwe-agent yokulinganisa; enye ukubuyisela i-agent yokulinganisa ngesisekelo se-agent yokulinganisa yokuqala, ebizwa ngokuthi usayizi wesibili.
Ngaphezu kokwenza ama-granules okubumba umjovo,i-carbon fiber eqoshiweinezinye izindlela zokusebenzisa, njengokwenziwa ngomatilasi we-carbon fiber, noma okwenziwe ngephepha le-carbon fiber. Ubude obudingekayo be-carbon fiber eqoshiwe buzoba bude kunobude be-fiber eqoshiwe yama-granules.
Ngaphezu kwalokho, ngaphezu kwemicu yekhabhoni eqoshiwe ngokungahleliwe, kukhona nemicu yekhabhoni eqoshiwe ehlanganisiwe. Le micu emfushane ikwisiqeshana esifushane ngaphambi kokuba idonswe yi-carbon fiber yohlobo oluthile olunqunyiwe, bese inqunywa ku-fibre emfushane inezici ze-bundle, equkethe inani le-resin lizoba ngaphezulu kakhulu kuneminye imicu emfushane.
