Theknoloji ea ho theha ea lisebelisoa tse phahameng tsa thermoplastic e fetisetsoa haholo ho tsoa ho metsoako ea resin ea thermosetting le theknoloji ea ho etsa tšepe. Ho ea ka lisebelisoa tse fapaneng, e ka aroloa ka ho bōpa, ho bōpa filimi habeli, ho bopa ha autoclave, ho bopa mokotla oa vacuum, ho bopa ha filament, ho etsa calendering, joalo-joalo. selelekela, e le hore o ka ba le kutloisiso e felletseng ea li-composites tsa thermoplastic carbon fiber.
1. Ho etsa filimi habeli
Double membrane molding, e tsejoang hape e le "resin membrane infiltration molding" ke mokhoa o ntlafalitsoeng ke k'hamphani ea ICI ho lokisa likarolo tse kopaneng ka prepreg. Mokhoa ona o loketse ho bōptjoa le ho sebetsa ha likarolo tse rarahaneng.
Ha filimi e etsoa habeli, prepreg e sehiloeng e behiloe lipakeng tsa likarolo tse peli tsa filimi ea resin e feto-fetohang le filimi ea tšepe, 'me karolo ea filimi e tiisitsoe ka tšepe kapa lisebelisoa tse ling. Ha ho etsoa mokhoa, ka mor'a ho futhumatsa mocheso oa ho theha, ho sebelisoa khatello e itseng ea ho etsa, 'me likarolo li holofala ho ea ka sebōpeho sa hlobo ea tšepe,' me qetellong li pholile 'me li bōpehile.
Nakong ea ho etsoa ha lifilimi tse peli, likarolo le lifilimi li atisa ho phutheloa le ho tlosoa. Ka lebaka la ho holofala ha filimi, thibelo ea ho phalla ha resin e tlase haholo ho feta ea hlobo e thata. Ka lehlakoreng le leng, filimi e holofetseng tlas'a vacuum e ka fana ka khatello e tšoanang likarolong, e ka ntlafatsang phapang ea khatello ea likarolo le ho netefatsa boleng ba ho theha.
2. Ho bopa ha pultrusion
Pultrusion ke ts'ebetso e tsoelang pele ea tlhahiso ea li-profile tse kopaneng tse nang le likarolo tse fapaneng. Qalong, e ne e sebelisetsoa ho etsa lihlahisoa tse bonolo tse nang le fiber ea unidirectional e matlafalitsoeng ka mahlakoreng a mabeli, 'me butle-butle ea fetoha lihlahisoa tse nang le likarolo tse tiileng, tse se nang letho le tse fapaneng tse rarahaneng. Ho feta moo, thepa ea profil e ka raloa ho fihlela litlhoko tsa meaho e fapaneng ea boenjiniere.
Pultrusion molding ke ho kopanya theipi ea prepreg (khoele) sehlopheng sa hlobo ea pultrusion. Prepreg e ka ba pultruded le prepreg, kapa e kenngoe ka thoko. Mekhoa e akaretsang ea ho emola ke faeba e kopanyang bethe le phofshoana e mokelikeli oa bethe.
3. Khatello Molding
Letlapa la prepreg le khaoloa ho ea ka boholo ba hlobo, le futhumatsoa ka sebōping sa ho futhumatsa ho mocheso o phahameng ho feta mocheso o qhibilihisang oa resin, ebe o romeloa ho lefu le leholo bakeng sa ho hatella ka potlako ho chesang. Potoloho ea ho bopa hangata e phethoa ka metsotsoana e mashome ho isa metsotsong e seng mekae. Mofuta ona oa mokhoa oa ho bōpa o na le tšebeliso e tlaase ea matla, theko e tlaase ea tlhahiso le tlhahiso e phahameng. Ke mokhoa o atileng haholo oa ho bopa ts'ebetsong ea li-composites tsa thermoplastic.
4. Ho theha mapheo
Phapang pakeng tsa filament matsoelintsoeke ea metsoako thermoplastic le metsoako thermosetting ke hore khoele prepreg (theipi) lokela ho futhumatsoa ho ea ho nolofatsa ntlha le ho futhumatsoa ka ntlha ya kopana ea mandrel.
Mekhoa e tloaelehileng ea mocheso e kenyelletsa mocheso oa conduction, mocheso oa dielectric, mocheso oa motlakase, mocheso oa mahlaseli a motlakase, joalo-joalo Ha ho futhumatsa mahlaseli a motlakase, mahlaseli a mahlaseli a kotsi (IR), microwave (MW) le mocheso oa RF le tsona li arotsoe ka lebaka la maqhubu a fapaneng a maqhubu kapa maqhubu. leqhubu la motlakase. Lilemong tsa morao tjena, tsamaiso ea ho futhumatsa ka laser le ultrasonic heatsist system le eona e 'nile ea ntlafatsoa.
Lilemong tsa morao tjena, tshebetso e ncha matsoelintsoeke e 'nile ea ntshetswa pele, ho akarelletsa le mohato oa ho bōpa mokhoa, ke hore, faeba e entsoe ka khoele prepreg (theipi) ka a phehile liquefaction bethe ea thermoplastic resin phofo, ebe ka ho toba leqeba ka mandrel; Ho phaella moo, ka mokhoa oa ho futhumatsa, ke hore, khoele ea carbon fiber prepreg (theipi) e kenngoa motlakase ka ho toba, 'me resin ea thermoplastic e qhibiliha ka ho futhumatsa le ho futhumatsa, e le hore khoele ea fiber (tape) e ka kenngoa lihlahisoa; Ea boraro ke ho sebelisa roboto ho etsa matsoelintsoeke, ho ntlafatsa ho nepahala le ho iketsetsa lihlahisoa tsa mapheo, kahoo e fumane tlhokomelo e kholo.
