Dab tsi yog thermoplastic ib cov khoom siv?
Nyob rau hauv xyoo tsis ntev los no, kev txhim kho fiberopastic composites raws li thermoplastic sau ua tau zoo, thiab kev tshawb fawb ntawm hom kev ua tau zoo no yog pib hauv lub ntiaj teb. Thermoplastic Composites Xa mus rau Thermoplastic polymers (Peek) li carbon fiber, xws li carbon fiber, fiber ntau, iav fiber ntau, Arylon Fiber, thiab lwm yam) ua cov ntaub ntawv lub zog.
Thermoplastic lipid-raws li composites tsuas yog suav nrog ntev fiber ntau fiberfercasted thermoplastic sib xyaw thermoplastic composites (cmt). Raws li kev siv sib txawv, lub resin matrix suav nrog peekpast, Pa thiab lwm yam tau flocodastic engeties engeties, Pa thiab lwm yam ua kom qhuav viscose aryl fiber ntau thiab boron fiber ntau. Nrog rau kev txhim kho cov thev naus laus zis ntawm thermoplastic Resin Matrix Composite thiab nws rov ua dua tshiab, kev txhim kho ntawm cov khoom siv sib xyaw no sai dua. Lub thermal supercompound tau suav rau ntau dua 30% ntawm tag nrho cov nyiaj ntawm tsob ntoo Matrix sib xyaw cov khoom hauv Tebchaws Europe thiab Amelikas.
Thermoplastic Matrix
Thermoplastic matrix yog ib hom ntawm thermoplastic cov khoom, nws muaj cov khoom siv kho kom zoo, tuaj yeem siv rau hauv kev tsim cov khoom siv ntau yam. Thermoplastic matrix yog tus cwj pwm los ntawm lub zog siab, muaj kub kub ua hauj lwm thiab zoo corrosion tsis kam.
Nyob rau tam sim no, Thermoplastic Resins thov rau cov teb aviation yog feem ntau siab resinant thiab siab ua haujlwm resin matrix, suav nrog peek, pps thiab pess. Ntawm lawv, Amorphous Pei yog cov qauv siv dav dav hauv lub dav hlau ntau dua li kev ua kom sov siab dua li ntawm nws qhov kub thiab txias thiab ua tiav.
Thermoplastic Resin muaj cov khoom siv hluav taws xob zoo dua, muaj zog ua kom zoo, muaj kev phom sij hauv cov khoom siv hnyav, vuam zoo dua, siv cov cwj pwm thiab kho cov yam ntxwv.
Cov khoom siv sib xyaw ua ke ntawm thermoplastic Resin thiab txhawb cov khoom siv muaj cov khoom siv ruaj khov, muaj kev tiv thaiv siab, siab ua rau muaj kev thev taus. Fiber ntau Prepreg tsis tas yuav tsum muab khaws cia ntawm qhov kub tsawg, tsis pub muaj lwm lub sijhawm khaws cia; Luv Txoj Kev Ncaj Ncees Me, Vuam, Kev Ua Haujlwm Siab, Yooj Yim Kho; Cov khib nyiab tuaj yeem rov ua dua tshiab; Cov khoom tsim kev ywj pheej loj yog qhov loj, tuaj yeem ua rau hauv cov qauv nyuaj, ua rau muaj kev yoog raws thiab ntau lwm yam zoo.
Txhawb nqa cov khoom siv
Cov yam ntxwv ntawm Thermoplastic Composites tsis tsuas yog nyob ntawm cov khoom ntawm Resin thiab txhawb cov fiber ntau, tab sis kuj tseem cuam tshuam nrog cov fiber ntau txhawb hom lub zog. Cov fiber ntau txhawb hom ntawm thermoplastic composites muaj peb daim ntawv cog lus: luv luv kev txhawb zog thiab kev txhawb nqa ntev ntev ntxiv.
Feem ntau, staple txhawb cov fibers yog 0.2 mus rau 0.6mm ntev, thiab vim tias feem ntau cov fibers tsawg dua 70μm inchers zoo dua li hmoov. Cov fiber ntau fiberfring thermoplectics feem ntau tsim los ntawm kev sib xyaw ua ke rau hauv tus molten thermoplastic. Cov fiber ntau thiab cov kev taw qhia random nyob rau hauv matrix ua nws yooj yim kom ua tiav kev ntub zoo. Piv rau ntev fiber ntau thiab nruam fiber ntau cov ntaub ntawv, luv luv fiber ntau yog qhov kev txhim kho yooj yim los tsim cov khoom siv tshuab. Staple fiber ntau composites nyiam ua moulded los yog extruded los ua cov khoom siv zaum kawg vim tias cov kab mob staple muaj tsawg dua ntawm fluidity.
Qhov ntev fiber ntau ntawm ntev fiber ntau txhawb kev sib xyaw yog feem ntau ntawm 20mm, uas feem ntau yog npaj los ntawm fiber ntau cov tshuaj txhuam los ntawm cov txhab thiab txiav mus rau qee qhov ntev. Cov txheej txheem ib txwm siv yog cov txheej txheem pultrusion, uas yog tsim los ntawm kev kos duab rov qab sib xyaw ntawm fiber ntau thiab thermoplastic resin los ntawm kev sib tuag tshwj xeeb tuag. Tam sim no, cov teeb meem ntawm cov fiber ntau txhawb peepoplastic mauv tuaj yeem ncav ntau dua 20gpa los ntawm fdm luam tawm, thiab cov khoom yuav zoo dua los ntawm kev txhaj tshuaj molding.
Cov fibers nyob rau hauv kev nruam fiber profearcites yog "nruam" thiab txawv nyob rau hauv ntev los ntawm ob peb meters rau ntau txhiab meters. Nruam fiber ntau cov composites feem ntau muab cov laminates, excregates, lossis cov qauv braided, thiab cov qauv los ntawm impegnating cov desircers nrog thermoplastic matrix.
Dab tsi yog cov yam ntxwv ntawm fiber ntau txhawb kev sib xyaw
Cov ntaub ntawv fiber ntau tam sim no yog ua los ntawm cov iav fiber ntau, carbon fiber ntau, thiab cov khoom siv matrix los ntawm winding, molding lossis pultrusion moulding txheej txheem. Raws li cov ntaub ntawv sib txawv sib txawv, cov fiber ntau cov roj fiberfed tuaj yeem muab faib ua cov fiber ntau (CFRP) thiab Aramid Fiber ReinferCed Composite (AGRP).
Fiber ntau txhawb cov khoom sib xyaw muaj cov yam ntxwv hauv qab no:
(1) Lub zog loj thiab cov khoom loj tshwj xeeb;
(2) Cov khoom siv khoom muaj cai tsim tau;
(3) Cov tshuaj corrosion zoo thiab kav ntev;
(4) Cov coefficient ntawm thermal expansion yog zoo li ntawm cov pob zeb.
Cov yam ntxwv no ua kom tau raws li cov kev tsim kho tshiab, yog li muaj ntau lub zog, txuas ntxiv, dej hiav txwv, cov qauv hydraulic thiab lwm thaj chaw.
Thermopopicastic Composites muaj kev txhim kho kev txhim kho zoo kawg nkaus
Raws li tsab ntawv ceeb toom, lub ntiaj teb thermoplastic Composites kev ua lag luam yuav tsum tau mus txog US $ 66.2 Billion los ntawm 2030, nrog cov lej sib txuas ntawm 7.8% thaum lub sijhawm kwv yees hauv lub sijhawm. Qhov nce no tuaj yeem yog los ntawm cov khoom lag luam cog hauv lub tshuab hluav taws xob thiab tsheb loj hlob thiab nthuav dav kev ua haujlwm. Thermoplastic Composites yog siv nyob rau hauv kev tsim kho cov tsev nyob, chaw nyob hauv tsev thiab dej. Cov khoom xws li muaj lub zog zoo, kev muaj zog zoo, thiab muaj peev xwm rov ua dua tshiab thiab ua kom rov qab ua cov ntawv thov thermoplastic ntau rau kev siv lub tsev.
Thermoplastic Composites yuav tseem siv los tsim cov hlau tso tsheb hlau luam, cov ncej xov tooj, cov tsheb nqaj hlau, cov kav dej, vaj huam sib luag thiab qhov rooj. Kev lag luam automotive yog ib qho ntawm cov ntawv thov tseem ceeb. Cov neeg tsim khoom yog tsom rau kev txhim kho roj kev ua haujlwm los ntawm kev hloov cov hlau thiab hlau nrog lub teeb ci ntsa iab thermoplastic ntau. Carbon fiber, nyhav ib-tsib ntau npaum li hlau, yog li nws pab txo qhov hnyav tag nrho ntawm lub tsheb. Raws li European Commission, cov carbon ntoos lub hom phiaj rau tsheb yuav raug tsa los ntawm 135 grams ib kilitaipastic sib xyaw hauv kev tsim kho tsheb lag luam.
Lub zeem muag ntawm Thermoplastic ntau cov khoom xyaw yog loj heev, thiab cov tuam ntxhab kev lag luam tau nqis peev ntau hauv kev tshawb fawb thiab kev txhim kho. Peb cia siab tias kev sib koom tes ntawm txhua tus neeg nyob rau yav tom ntej, domestic composite tshuab yuav ua tau nyob rau hauv txoj hauj lwm thoob ntiaj teb.
