Qhov txawv ntawm Cov Txheej Txheem
Cov pa roj carbon fiber ntau yog ua los ntawm pultrusion, winding thiab dov.
Cov txheej txheem no muaj lawv tus kheej qhov zoo thiab qhov tsis zoo: pultrusion molding yog ib qho yooj yim kom ua tiav fiber ntau txuas ntxiv, tab sis tsis tuaj yeem ua tiav qhov kev hloov pauv ntawm lub kaum sab xis ntawm cov fiber ntau.
Cov txheej txheem winding tuaj yeem tsim raws li cov khoom lag luam kev ntxhov siab winding txoj cai, tuaj yeem muab kev ua si tag nrho rau lub zog ntawm cov fiber ntau, qhov siab tshaj plaws lav ntawm cov khoom siv uas xav tau los ntawm cov yeeb nkab, tab sis kev hloov pauv ntawm winding molding yog me me, tsis tuaj yeem qhwv. nyob ib ncig ntawm txhua yam qauv ntawm cov khoom.
Cov txheej txheem dov muaj qib siab ntawm kev siv tshuab automation, cov yeeb nkab tiav yog siab dua hauv cov txheej txheem pultrusion, thiab cov tsos kuj tseem tuaj yeem ua 3k weaving qauv, uas yog siv rau ntau yam, thiab tus nqi kuj yog siab dua.
Kev xaiv cov khoom siv raw
Lub zog ntawm cov pa roj carbon fiber ntau yog txiav txim siab los ntawm cov khoom siv fiber ntau, cov khoom sib txawv ntawm cov pa roj carbon fiber ntau hauv cov khoom siv thiab cov nqi sib txawv kuj tseem loj heev, thiab thaum kawg txiav txim siab qhov kev ua tau zoo thiab tus nqi ntawm cov roj carbon fiber ntau.
Kev xaiv ntawm resin yuav tsum tsis txhob raug ignored, lub luag hauj lwm tseem ceeb ntawm cov resin yog lo cov carbon fibers ua ke, faib cov load ntawm cov carbon fibers, thiab tiv thaiv cov carbon fibers los ntawm ib puag ncig influences, kev xaiv ntawm resin matrix yuav tsum ua raws li cov qauv ntawm yooj yim kho, muaj zog nplaum quab yuam, tsawg shrinkage, thiab zoo mechanical zog.
Khoom siv ntawm mandrel
Cov pwm tseem ceeb ua los ntawm cov khoom sib txawv muaj qhov cuam tshuam rau qhov raug thiab ua haujlwm ntawm cov yeeb nkab.
Qee qhov qis kawg carbon fiber ntau ntau lawm siv polyvinyl cawv-xuab zeb, ntoo-fiberglass thiab lwm yam ntaub ntawv los ua winding core pwm. Txawm li cas los xij, cov ntaub ntawv no tsis tuaj yeem tiv taus qhov kub thiab txias siab tshaj 150 degree thiab qib ntawm kev ua haujlwm yog ntxhib dhau los ua cov roj carbon fiber ntau zoo.
Hlau thiab duralumin yog ob feem ntau siv cov ntaub ntawv tseem ceeb. Hlau yog denser thiab nyuaj dua duralumin, tab sis nws coefficient ntawm thermal expansion tsis siab li ntawm duralumin. Cov pa roj carbon zoo siab yuav tsum tau kho ntawm qhov kub thiab txias, thiab cov tshuab epoxy resin tuaj yeem kho tau mus txog 170 degree. Lub sab hauv curing siab generated los ntawm lub thermal expansion ntawm duralumin yog ib txoj hauv kev zoo los txhim kho qhov ntom ntom thiab cov khoom siv ntawm cov pa roj carbon raj.
Technical cov ntsiab lus ntawm demolding
Txhawm rau kom yooj yim demolding, tus neeg sawv cev tso tawm feem ntau yog siv rau saum npoo ntawm mandrel ua ntej winding. Txawm li cas los xij, nyob rau hauv kev tsim cov pa roj carbon fiber ntau cov raj, cov organic-raws li cov neeg ua haujlwm tso tawm tuaj yeem nkag mus rau hauv cov resin thaum lub sijhawm kho, ua rau muaj kev puas tsuaj rau cov raj tiav thiab cuam tshuam rau lawv cov kev ua tau zoo.
Txhawm rau zam qhov no, xaiv tus neeg sawv cev uas muaj fluorine tso tawm tuaj yeem txo qhov tsis xws luag.
Mandrels yuav tsum tau siv ntau zaus, yog tias koj siv tig los yog clamping kom tshem tawm lub taub hau thaum demolding, nws yuav ua rau muaj kev puas tsuaj rau saum npoo ntawm mandrel.
Koj yuav tsum tau siv cov nplaum kub kub los kho qhov txhab los yog siv vuam, thiab tom qab ntawd sib tsoo rau hauv qhov chaw, txwv tsis pub, nws yuav cuam tshuam ncaj qha rau cov khoom ntawm cov khoom ntawm cov pa roj carbon fiber ntau tom ntej.
Cov pa roj carbon fiber ntau muaj qhov ua tau zoo dua li cov yeeb nkab hlau, xws li lub zog siab, corrosion kuj, me me coefficient ntawm thermal expansion, creep resistance, self-lubricating, qaug zog tsis kam, ntev kev pab cuam lub neej, tab sis kuj muaj zog nqus thiab seismic, tseem ceeb tshaj. yog qhov ceev ntawm qhov zoo me me thiab lub teeb yuag, tuaj yeem ua tib yam li cov yeeb nkab steel qhov hnyav txo ntau dua 80%.
Tab sis los ntawm daim ntawv thov ntawm qhov teeb meem no, carbon fiber tubes muaj peev xwm tiag tiag muaj kev cuam tshuam cov saum toj no kev ua tau zoo zoo, los yog los ntawm qhov tseeb zus tau tej cov ntau yam technical.
