Ubuchwepheshe bokwakha bezinhlanganisela ze-thermoplastic ezisebenza kahle kakhulu butshalwa kabusha busuka ku-thermosetting resin composite kanye nobuchwepheshe bokwenza insimbi.Ngokusho kwemishini ehlukene, ingahlukaniswa ibe ukubumba, ukubumba ifilimu kabili, ukubumba kwe-autoclave, ukubumba kwesikhwama se-vacuum, ukubunjwa kwe-filament, ukubunjwa kwe-calendering, njll. Kulezi zindlela, sizokhetha izindlela ezimbalwa zokubumba ezisetshenzisiwe ukuze sikunikeze kafushane isingeniso, ukuze ube nokuqonda okuphelele kwezinhlanganisela ze-thermoplastic carbon fibre.
1. Ukwenza ifilimu kabili
Ukubumba ulwelwesi oluphindwe kabili, okwaziwa nangokuthi ukubumba kokungena kwe-resin membrane, kuyindlela eyakhiwe yinkampani ye-ICI yokulungisa izingxenye eziyinhlanganisela nge-prepreg.Le ndlela ivumela ukubunjwa nokucubungula izingxenye eziyinkimbinkimbi.
Ekwakheni ifilimu ephindwe kabili, i-prepreg enqunyiwe ifakwa phakathi kwezingqimba ezimbili zefilimu ye-resin eguquguqukayo eguquguqukayo nefilimu yensimbi, futhi i-periphery yefilimu ivalwe ngensimbi noma ezinye izinto.Enqubweni yokubunjwa, ngemva kokushisa ekushiseni okwakhayo, ingcindezi ethile yokwakha isetshenziswa, futhi izingxenye zikhubazekile ngokuvumelana nokuma kwesikhunta sensimbi, futhi ekugcineni zipholile futhi zibunjwe.
Enqubweni yokwakhiwa kwefilimu ephindwe kabili, izingxenye namafilimu kuvame ukupakishwa futhi kufakwe vacuumized.Ngenxa yokukhubazeka kwefilimu, ukuvinjelwa kokugeleza kwe-resin kuncane kakhulu kunokwesikhunta esiqinile.Ngakolunye uhlangothi, ifilimu ekhubazekile ngaphansi kwe-vacuum ingakwazi ukufaka ingcindezi efanayo ezingxenyeni, ezingathuthukisa ukuhlukahluka kokucindezela kwezingxenye futhi kuqinisekiswe ikhwalithi yokwenza.
2. Ukubunjwa kwe-pultrusion
I-Pultrusion iyinqubo yokukhiqiza eqhubekayo yamaphrofayili ayinhlanganisela anezigaba ezihlukene.Ekuqaleni, yayisetshenziselwa ukukhiqiza imikhiqizo elula ene-unidirectional fiber reinforced solid cross-section, futhi kancane kancane yathuthukiswa yaba imikhiqizo eneziphambano eziqinile, ezingenalutho neziyinkimbinkimbi.Ngaphezu kwalokho, izakhiwo zamaphrofayili zingaklanywa ukuze zihlangabezane nezidingo zezakhiwo ezihlukahlukene zobunjiniyela.
I-pultrusion molding iwukuhlanganisa itheyiphu ye-prepreg (umucu) eqenjini lesikhunta se-pultrusion.I-prepreg i-pultruded futhi i-prepreg, noma ikhuleliswa ngokuhlukana.Izindlela zokumilisela ezijwayelekile ukumilela okuxutshwa kwefayibha kanye nokumiliselwa kombhede okuyimpushana.
3. I-Pressure Molding
Ishidi le-prepreg lisikwa ngokulingana nobukhulu besikhunta, lishiswe esithandweni sokushisa liye ezingeni lokushisa elingaphezu kwezinga lokushisa elincibilikayo le-resin, bese lithunyelwa kufayizi elikhulu ukuze licindezelwe ngokushesha.Umjikelezo wokubumba uvame ukuqedwa emashumini amasekhondi kuya emaminithini ambalwa.Lolu hlobo lwendlela yokubumba lunokusetshenziswa kwamandla okuphansi, izindleko zokukhiqiza eziphansi kanye nokukhiqiza okuphezulu.Kuyindlela ejwayelekile kakhulu yokubumba enqubweni yokubumba yezinhlanganisela ze-thermoplastic.
4. Ukwakheka kwamawindi
Umehluko phakathi kokusonteka kwe-filament yezinhlanganisela ze-thermoplastic nezinhlanganisela ze-thermosetting ukuthi intambo ye-prepreg (i-tape) kufanele ishiswe endaweni yokuthambisa futhi ishise endaweni yokuxhumana ye-mandrel.
Izindlela zokushisa ezivamile zihlanganisa ukufudumeza kwe-conduction, ukufudumeza kwe-dielectric, ukufudumeza kwe-electromagnetic, ukufudumeza kwe-electromagnetic radiation, njll. Ekushiseni kwemisebe ye-electromagnetic, imisebe ye-infrared (IR), i-microwave (MW) kanye nokufudumeza kwe-RF nakho kuhlukaniswe ngenxa yobude obuhlukile noma imvamisa. we-electromagnetic wave.Eminyakeni yamuva nje, ukufudumala kwe-laser kanye nesistimu yokushisa ye-ultrasonic nayo yakhiwe.
Eminyakeni yamuva, inqubo entsha yokujiya iye yathuthukiswa, kuhlanganise nesinyathelo esisodwa sokubumba indlela, okungukuthi, i-fiber yenziwe ibe yintambo ye-prepreg (i-tape) ngokubilisa umbhede we-liquefaction we-thermoplastic resin powder, bese ulimaza ngokuqondile i-mandrel;Ngaphezu kwalokho, ngokusebenzisa indlela yokushisa yokwakha, okungukuthi, intambo ye-carbon fiber prepreg (i-tape) ifakwe ugesi ngokuqondile, futhi i-resin ye-thermoplastic iyancibilika ngokufaka ugesi nokushisa, ukuze intambo ye-fiber (i-tape) ingalimala ibe yimikhiqizo;Okwesithathu ukusebenzisa irobhothi ekujikeni, ukuthuthukisa ukunemba kanye ne-automation yemikhiqizo yokusonta, ngakho-ke ithole ukunakwa okukhulu.
