Iyo yekugadzira tekinoroji yeakakwira performance thermoplastic composites inonyanya kuisirwa kubva kune thermosetting resin composites uye simbi yekugadzira tekinoroji. Maererano nemichina yakasiyana-siyana, inogona kugoverwa mukugadzira, kuumbwa kwemafirimu maviri, autoclave molding, vacuum bag molding, filament winding molding, calendering molding, nezvimwewo. sumo, kuitira kuti iwe ugone kuve nekunzwisisa kwakadzama kwe thermoplastic kabhoni fiber composites.
1. Kugadzira firimu kaviri
Kaviri membrane molding, inozivikanwawo seresin membrane infiltration molding, inzira yakagadziridzwa neICI kambani kugadzirira zvikamu zvakasanganiswa ne prepreg. Iyi nzira inokodzera kuumbwa uye kugadziriswa kwezvikamu zvakaoma.
Mukuumbwa kwemafirimu maviri, iyo prepreg yakachekwa inoiswa pakati pematanho maviri eakaremara anochinjika resin firimu uye simbi firimu, uye periphery yefirimu yakavharwa nesimbi kana zvimwe zvinhu. Mukugadzira, mushure mekupisa kune tembiricha yekugadzira, imwe yekumanikidza yekugadzira inoiswa, uye zvikamu zvinoremara zvichienderana nechimiro chesimbi mold, uye pakupedzisira yakatonhodzwa nekuumbwa.
Mukuita kwemafirimu maviri ekuumba, zvikamu uye mafirimu zvinowanzoiswa mukati uye vacuumized. Nekuda kwekuremara kwemufirimu, kudzorwa kwekuyerera kweresin kudiki pane kweiyo yakaoma mold. Kune rimwe divi, firimu rakaremara pasi pevacuum rinogona kumanikidza yunifomu pazvikamu, izvo zvinogona kuvandudza kudzvanywa kwezvikamu uye kuve nechokwadi chekuumba mhando.
2. Pultrusion molding
Pultrusion inoenderera mberi yekugadzira maitiro eanosanganiswa profiles ane anogara achiyambuka-chikamu. Pakutanga, yaishandiswa kugadzira zvigadzirwa zviri nyore zvine unidirectional fiber yakasimbiswa yakasimba muchinjiko-chikamu, uye zvishoma nezvishoma yakagadziridzwa kuita zvigadzirwa zvine yakasimba, maburi uye akasiyana-siyana akaomarara. Uyezve, zvivakwa zveprofile zvinogona kugadzirwa kuti zvisangane nezvinodiwa zveakasiyana mainjiniya zvimiro.
Pultrusion molding ndeyekubatanidza iyo prepreg tepi (yarn) muboka re pultrusion molds. Iyo prepreg inogona kunge yakanyungudutswa uye prepreg, kana kuisirwa zvakaparadzana. Iyo yakajairika nzira yekumirisa ndeye faibha blending impregnation uye hupfu inonyungudutsa mubhedha impregnation.
3. Pressure Molding
Iyo prepreg sheet inochekwa zvinoenderana nehukuru hwe mold, inopisa muchoto chekudziya kusvika kune tembiricha yakakwira kupfuura tembiricha yekunyungudika yeresin, uye yozotumirwa kune hombe kufa kwekukurumidza kupisa. The molding cycle inowanzopedzwa mumakumi emasekonzi kusvika kumaminitsi mashoma. Mhando iyi yekuumba nzira ine yakaderera simba rekushandisa, yakaderera mutengo wekugadzira uye yakakwirira kubereka. Iyo ndiyo yakajairika nzira yekuumba mukuumbwa kweiyo thermoplastic composites.
4. Kugadzira mhepo
Musiyano uripo pakati pe filament winding ye thermoplastic composites uye thermosetting composites ndewekuti prepreg warn (tepi) inofanira kupisa kusvika pakupfava uye kupisa panzvimbo yekubata ye mandrel.
Idzo dzinozivikanwa nzira dzekupisa dzinosanganisira conduction heat, dielectric heat, electromagnetic heat, electromagnetic radiation heat, etc. Mukupisa kweelectromagnetic radiation, infrared radiation (IR), microwave (MW) uye RF kudziyisa zvakakamurwawo nekuda kwekusiyana kwewavelength kana frequency. ye electromagnetic wave. Mumakore achangopfuura, laser yekudziya uye ultrasonic yekudziya system yakagadziridzwa zvakare.
Mumakore achangopfuura, nzira itsva yekupetera yakave yakagadzirwa, kusanganisira imwe-nhanho yekuumba nzira, ndiko kuti, iyo fiber inogadzirwa kuva prepreg yarn (tepi) nekubikira liquefaction mubhedha we thermoplastic resin upfu, uye ipapo zvakananga ronda pamusoro mandrel; Mukuwedzera, kuburikidza nekupisa kwekugadzira nzira, ndiko kuti, carbon fiber prepreg yarn (tepi) yakanyatsogadziriswa magetsi, uye thermoplastic resin inonyungudutswa nemagetsi uye kupisa, kuitira kuti fiber yarn (tepi) inogona kukuvadzwa muzvigadzirwa; Yechitatu ndeye kushandisa robhoti kupeta, kuvandudza iko kurongeka uye otomatiki yezvigadzirwa zvemhepo, saka yakagamuchira kutariswa kukuru.
