Cov hom fiber ntau zog dua thermoplastics
Muab faib ua daim ntawv fais fab, cov thermoplastic composites tau ua raws li cov theem nram qab no: luv fiber ntau reinforced thermoplastic composites, ntev fiber ntau reinforced thermoplastic composites, thiab txuas ntxiv fiber ntau thermoplastic composites.
Luv Fiber Muaj Thermoplastic (SFT)
Feem ntau yog hais txog ib hom kev siv thermoplastic uas muaj qhov ntev ntawm qhov ntev dua 1 hli thiab qhov ntev ntawm 0.2-0.7 hli.
Cov phom ntev luv dua cov thermoplastic composites yog superior rau cov ntaub ntawv uas tsis muaj zog ntawm cov duab matrix nyob hauv lub zog, kev nruj, thiab qhov chaw dimensional. Siv dav hauv kev lag luam, kev ua lag luam, tshuab hluav taws xob / khoom siv hluav taws xob, nkoj, aerospace thiab lwm yam.
Cov kab mob ntev ntev siv zog thermoplastics (LFT los yog LFRT)
Yuav kom kov tau cov fiber ntau ntawm cov teeb meem nyob rau hauv luv-fiber-reinforced thermoplastics thiab ua rau cov tsis muaj mechanical zog, cov khoom tshiab tau tsim.
Cov tshuaj fiber ntau ntev dua yog thermoplastics xws li cov thermoplastics xws li polypropylene, polyamide (nylon), tus tsiaj, polyphenylene sulfide, polyether sulfone, thiab polyether ether ketone; iav fiber, carbon fiber, thiab aramid fiber ntau yog siv cov ntaub ntawv coj los siv. . Cov khoom ua tiav ib nrab yog ua ntawm fiber ntau nrawm thiab thermoplastics los ntawm extrusion, pelletizing los yog ntsim txoj kev, thiab ces txhaj los yog molded rau cov khoom.
Txoj kev loj hlob ntawm LFT yog tsuas yog tsav los ntawm lub tsheb kev lag luam. Tsis tas li ntawd, yuav muaj kev txhim kho zoo hauv cov neeg siv khoom thiab khoom lag luam. Raws li ib daim ntawv tshaj tawm tawm los ntawm lub tuam txhab muaj kev lag luam thoob ntiaj teb, lub ntiaj teb no siv LFT hauv 2017 mus txog 313,400 tons.
Daim iav lev reinforced thermoplastic thermoplastic ntawv (GMT)
Ib daim ntawv zoo li cov khoom siv muaj cov thermoplastic cob ua matrix thiab iav fiber ntau li cov pob txha.
Polypropylene yog siv los ntawm plastics thiab PET, PBT los yog polycarbonate kuj siv tau. GMT siv high-speed presses los yog presses rau cov khoom.
GMT cov ntaub ntawv yog siv rau hauv kev lag luam automotive vim lawv kev ua tau zoo dua cov ntaub ntawv thermosetting thiab cov nuj nqi zoo. Nyob rau tib lub sijhawm, lawv kuj siv rau kev tsim khoom ntawm kab npuas yas, kab kos dashboard, lub npog cav, thiab cov khoom suab nrov. Pob zeb tsheb npog, lub rooj ncej, roj teeb, lub qhov rooj, lub hau npog, khib phom thiab lub ru tsev thiab lwm yam tsheb.
Nruam Cov Fiber Ntau Cov Khoom Ntsuas Kub (CFRT)
CFRT cov khoom siv muaj xws li fiber ntau prepregs, prepregs npuag, txuam yarns, pultruded khoom, thiab lwm yam.
Cov iav fiber ntau thiab cov fibre fiber yog cov khoom siv rau cov cuab yeej ua kom tiav rau cov thermoplastics tas li. Cov tshuaj siv loj yog cov polyamide (PA), polypropylene (PP), polyetherimide (PEI), polyphenylene sulfide (PPS), thiab polyether. Ether ketones (PEEK) thiab lwm yam.
Txoj kev loj hlob ntawm cov kev lag luam aerospace yog ib qho kev tsav tsheb loj rau txoj kev loj hlob ntawm kev siv fais fab kev lag luam. Vim tias muaj cov thev naus laus zis muaj zog thermoplastics muaj kev siab tawv thiab kev puas tsuaj, thiab ua kom zoo tshaj qhov kub siab, qhov khoom no tau nthuav dav los ntawm txoj kev ua lag luam av sai sai thaum nws tawm los, thiab tau pib qhia qhov tseem ceeb hauv daim ntawv thov ntawm aircraft. Tsis tas li ntawd, kev siv cov thermoplastics tas li uas siv cov thev naus laus zis muaj zog siv lawv cov kev siv hauv cov tsheb, cov khoom siv ua si, kev thauj mus los, kev lag luam, kev kho mob, thiab cov lag luam marine rau xyoo tas los.
Ntxiv rau qhov saum toj-hais ntau lub ntsiab mainstream reinforced thermoplastics, thermoplastic composite sandwich structures kuj tau tawm nyob rau hauv xyoo tas los. Cov khoom siv no yog ib cov qauv nyuaj uas ua los ntawm kev ntxiv ib cov khoom siv hauv nruab nrab ntawm ob qho tib si thiab tuaj yeem txhim kho qhov kev ua tau zoo los ntawm kev ntxiv ib qho me me ntawm qhov hnyav, thiab yog li dav dav siv hauv cov tsheb, cov thawv, thiab cov tuam tsev.
