LFT Fiber Automotive Thermoplastic Solutions
Tawm tsam keeb kwm yav dhau los ntawm kev txuag hluav taws xob thoob ntiaj teb, txo qis emissions thiab kev loj hlob sai ntawm lub zog tshiab tsheb, tsheb lub teeb hnyav tau dhau los ua ib qho tseem ceeb hauv kev lag luam. Qhov no tsis yog tsuas yog kev txhim kho kev siv hluav taws xob xwb, tab sis kuj yog txoj hauv kev tseem ceeb rau kev ua tiav lub hom phiaj ntawm carbon neutrality. Tawm tsam qhov keeb kwm yav dhau no, ntev - fiber ntau ntxiv cov khoom sib xyaw, nrog rau lawv qhov kev ua tau zoo tshwj xeeb, yog ntsiag to hloov cov khoom siv hauv kev tsim tsheb, muab kev sib tw zoo rau cov khoom siv hlau tsoos.
Long fiber reinforced materials are composite materials formed by embedding continuous or long-cut fibers (usually with a length >10mm) rau hauv thermoplastic (xws li polypropylene PP, nylon PA) los yog thermosetting resins (xws li epoxy resin) raws li matrix. Piv nrog luv luv- fiber ntau cov ntaub ntawv, cov fibers ntev tsim ib qho kev ua tiav network ntau dua hauv matrix, yog li txhim kho cov khoom siv kho tshuab ntawm cov khoom.
Dab tsi yog qhov zoo ntawm cov khoom siv fiber ntau ntev?
Zoo heev mechanical zog:Siab zog thiab siab tawv, Muaj zog bearing muaj peev xwm.
Kev cuam tshuam zoo:Ntev fibers tuaj yeem tiv thaiv kev tawg tawm.
Zoo heev corrosion kuj thiab durability:Ntev- fiber ntau ib puag ncig muaj ntuj tiv taus qee qhov chaw tshwj xeeb thiab tsis tshua muaj kev xeb thiab lwm yam mob.
Hnav tsis kam:Nyob rau hauv dynamic loads (xws li cov khoom ncua kev kawm ntawv), nws lifespan ntev dua li cov hlau.
Lub teeb yuag:Qhov ceev yog qis dua li cov khoom siv hlau.
Siab tsim kev ywj pheej:Muaj peev xwm ntawm integrally tsim complex qauv.
Environmental Protection thiab Sustainability:Ntev fiber ntau pellets tuaj yeem rov ua dua tshiab, uas yog raws li lub tswv yim ntawm kev tiv thaiv ib puag ncig.
Thaum lub fiber ntev mus txog qhov tseem ceeb ntev, nws qhov kev txhawb zog muaj peev xwm ua tau ob npaug los yog ntau zaus ntau zaus. Qhov no tau pab txhawb kev ua tau zoo ntawm cov khoom siv fiber ntau ntev. Cov khoom siv fiber ntau ntev ntawm LFT®-G tau zoo- paub rau ntau tus neeg siv khoom. Raws li cov ntaub ntawv peb muab, cov ntsiab lus tsim nyog tshaj plaws ntawm cov ntaub ntawv tuaj yeem pom muaj qhov tsim nyog thiab ua tau zoo. Tam sim no, peb yuav qhia thiab xa mus rau cov ntaub ntawv technical ntawm LGF40 PA6 (nylon 6) cov khoom ua tus sawv cev.

Lub tsheb twg tuaj yeem ua los ntawm cov khoom siv fiber ntau ntev?
Structure Cheebtsam:pem hauv ntej -end module, lub rooj ncej, bumper beam, roj teeb bracket
Sab hauv qhov chaw:dashboard, qhov rooj sab hauv panels, center console brackets
Lub zog thiab chassis Cheebtsam:roj teeb vaj tsev, cav hood, roj lauj kaub, ncua kev tswj tuav caj npab
Cov khoom tshwj xeeb rau lub zog tshiab
Roj teeb qhov system:Roj teeb vaj tsev (nplaim retardant, electromagnetic shielding yuav tsum)
Hydrogen roj cia tank:Cov pa roj carbon fiber ntau lub qhov txhab ua kom muaj zog, siab tiv taus thiab tiv thaiv -permeation
Saib cov khoom siv fiber ntau ntev los ntawm qhov sib txawv
Los ntawm qhov kev xav ntawm cov ntaub ntawv tshawb fawb, qhov paub tsis meej ntawm ntev -fiber reinforced composites nyob hauv lawv cov qauv tsim tshwj xeeb. Cov khoom no tau tsim cov cuab yeej cuab tam deb tshaj li ntawm ib qho khoom siv los ntawm cov organically sib txuas siab - lub zog fibers nrog lub polymer matrix. Thaum cov khoom raug rau sab nraud quab yuam, cov fibers dais lub ntsiab load, thaum lub matrix yog lub luag hauj lwm rau kho txoj hauj lwm ntawm fibers thiab xa cov kev ntxhov siab. Hauv kev siv tswv yim, cov khoom siv no ua rau pom cov khoom muaj txiaj ntsig zoo, muaj lub zog siab thaum tswj xyuas qhov ntom ntom.
Hauv kev lag luam kev tsim tsheb, kev siv cov khoom siv fiber ntau ntev - nthuav dav los ntawm ib tus neeg cov khoom mus rau tag nrho lub tsheb architecture. BMW tau pib siv cov pa roj carbon fiber reinforced yas los tsim cov neeg nrog caij tsheb, ua kom muaj qhov hnyav txo. Kev tsim kho tshiab txuas ntxiv ntawm cov txheej txheem tsim khoom tau ua rau txoj hauv kev rau kev siv dav dav ntawm - cov khoom siv fiber ntau. Cov kev siv thev naus laus zis no niaj hnub tawg los ntawm cov fwj hauv cov khoom loj thiab kev siv cov khoom sib xyaw.
Los ntawm cov kev xav ntawm kev lag luam thiab ib puag ncig cov txiaj ntsig, ntev - cov khoom siv fiber ntau tau pom tias muaj kev sib tw muaj zog. Txawm hais tias tus nqi ntawm cov khoom siv thawj zaug yuav siab dua me ntsis, xav txog lub sijhawm ntev - lub zog -txuag cov txiaj ntsig los ntawm kev txo qhov hnyav, nws cov nqi sib tw tau maj mam tshwm sim. Kev ntsuam xyuas lub neej qhia tau hais tias hom khoom siv no siv lub zog tsawg dua thaum lub sijhawm tsim khoom, muaj qhov cuam tshuam loj ntawm emission txo thaum lub sijhawm siv, thiab tseem muaj txiaj ntsig zoo hauv kev rov ua dua thiab siv.
Los ntawm kev xaiv cov khoom tsim nyog, kev ua kom zoo dua qub thiab kev tsim kho tshiab, ntev - cov ntaub ntawv fiber ntau tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv tsheb thiab txo cov nqi tag nrho lub neej. Ntau qhov kev xav tau qhia tias kev xaiv ntev - cov ntaub ntawv fiber ntau ua cov khoom siv raw rau cov khoom siv tsheb yog qhov tsim nyog thiab kev xaiv tsav tsheb.
