Nyob rau hauv lub ntiaj teb kev lag luam automotive uas hloov pauv sai sai, kev sib tw mus raukev txav mus los ntawm hluav taws xob (EV)thiab kev siv roj tsawg tau hloov pauv qhov kev tsom mus rau kev ua haujlwm ntawm lub cav mus rau kev tshawb fawb txog khoom siv. Lub hauv paus ntawm kev hloov pauv no yog lub tswv yim ntawmKev Ua Kom Lub Tsheb Sib NqusTxawm hais tias cov hlau nplaum siab heev thiab cov carbon fiber feem ntau nyiag cov xov xwm tseem ceeb,fiberglass rovingtau tshwm sim los ua tus phab ej uas tsis tau muaj leej twg paub, muab kev daws teeb meem uas pheej yig thiab ua tau zoo rau kev tsim cov khoom siv tsheb tiam tom ntej.

Kev Hloov Pauv Tswv Yim: Vim Li Cas Fiberglass Roving?

Lub tuam txhab tsheb tam sim no tab tom ntsib ob qho teeb meem: txo cov pa roj carbon rau cov tsheb siv lub cav sab hauv (ICE) thiab nthuav dav cov roj teeb rau Cov Tsheb Hluav Taws Xob (EVs). Kev txo qhov hnyav yog qhov zoo tshaj plaws los rub ob qho tib si. Cov ntaub ntawv kev lag luam qhia tias aTxo qhov hnyav ntawm lub tsheb 10%tuaj yeem ua rau muaj ib qhoKev txhim kho 6–8% hauv kev siv roj tsawglossis kev nce ntxiv ntawm EV mais.

Fiberglass roving, tshwj xeeb tshaj yogkev rov qab ncaj qhathiabsib dhos roving, muaj cov khoom tshwj xeeb uas ua rau nws tseem ceeb rau cov neeg muab khoom Tier-1 niaj hnub no:

Qhov Sib Piv Zoo Tshaj Plaws Rau Lub Zog:Txawm hais tias nws sib dua li hlau lossis txhuas, cov khoom siv uas muaj iav fiber roving tuaj yeem tiv taus kev ntxhov siab loj heev.

Kev Tiv Thaiv Kev Xeb:Tsis zoo li cov hlau, fiberglass tsis xeb, ua rau lub chassis thiab cov khoom hauv qab lub cev ntev dua.

Kev Tsim Qauv Yooj Yim:Kev siv roving hauv cov txheej txheem zoo likev sib txhuamthiabSMC (Cov Ntawv Moulding Compound)tso cai rau cov geometries nyuaj uas tsis yooj yim sua kom ua tiav nrog cov hlau stamping ib txwm muaj.

Cov Ntawv Thov Tseem Ceeb hauv Cov Tsheb Next-Gen

Qhov ua tau ntau yam ntawmfiberglass rovingtau pom zoo tshaj plaws los ntawm nws cov ntawv thov sib txawv hauv cov qauv tsheb niaj hnub.

1. Cov Khoom Siv Rau Lub Roj Teeb EV

Raws li qhov hnyav tshaj plaws hauv lub tsheb fais fab, lub roj teeb xav tau lub tsev uas tsis yog tsuas yog sib dua xwb tab sis kuj tiv taus hluav taws thiab tiv thaiv hluav taws xob.Fiberglass roving, thaum ua ke nrog cov thermoset resins tshwj xeeb, tsim ib lub thawv sib xyaw uas tiv thaiv cov roj teeb thaum pab txhawb rau qhov kev ruaj khov ntawm lub tsheb.

2. Cov Nplooj Nplooj thiab Cov Tshuab Ncua

Cov nplooj ntoos hlav hlau ib txwm muaj hnyav thiab yooj yim qaug zog. Los ntawm kev siv cov fiberglass roving modulus siab hauv cov txheej txheem pultrusion, cov chaw tsim khoom tuaj yeem tsim cov nplooj ntoos hlav sib xyaw uas yog txog liSib dua 75%dua li lawv cov hlau counterparts, muab cov khoom zoo dua dampening thiab caij du dua.

3. Cov ntaub thaiv hauv qab lub cev thiab cov brackets tsim kho

Lub cev tsheb hauv qab raug cov khib nyiab thiab dej noo ntawm txoj kev. Cov thermoplastics uas muaj fiberglass (CFRTP) siv cov fiber ntev ua rau muaj kev tiv thaiv zoo dua, tiv thaiv cov "organ tseem ceeb" ntawm lub tsheb yam tsis ntxiv cov hlau hnyav.

Lub Luag Haujlwm ntawm Kev Siv Tshuab Roving Siab: E-Glass vs. High-Modulus Glass

Yuav kom ua tau raws li qhov xav tau ntawm kev lag luam tsheb, tsis yog txhua txoj kev fiberglass roving yog tsim sib npaug. Kev xaiv ntawm cov fiber txiav txim siab qhov kawg ntawm qhov ua tau zoo.

E-iav Roving:Tus qauv kev lag luam, muab kev rwb thaiv hluav taws xob zoo heev thiab cov khoom siv kho tshuab ntawm tus nqi sib tw. Nws tseem yog qhov mus-rau rau cov vaj huam sib luag sab hauv thiab sab nraud.

Kev Roving High-Modulus (HM):Rau cov khoom siv uas xav tau kev ruaj khov heev, xws li cov ncej ru tsev lossis cov thav qhov rooj, HM roving muab cov modulus uas txuas qhov sib txawv ntawm cov iav fiber ib txwm muaj thiab cov carbon fiber kim.

At [CQDJ], peb tshwj xeeb hauv kev tsim cov fiberglass roving nrog cov khoom siv siab heevcov txheej txheem ntsuas qhov loj me—cov tshuaj pleev xim siv rau cov fibers. Peb qhov kev ntsuas qhov loj me ua kom muaj kev sib txuas zoo meej ntawm cov fiber thiab cov resin matrix (txawm tias nws yog Epoxy, Polyester, lossis Polypropylene), uas yog qhov tseem ceeb rau kev tiv thaiv kev tawg thiab ua kom muaj kev ruaj khov ntev hauv cov chaw muaj kev co siab hauv tsheb.

Kev Ruaj Ntseg: Kev Lag Luam Txhua Lub Caij ntawm Cov Iav Fiber

Ib qho kev nkag siab yuam kev feem ntau yog tias cov khoom sib xyaw ua ke tsis zoo rau ib puag ncig. Txawm li cas los xij, qhov kev txav mus rauKev siv thermoplastic roving (TP)tab tom hloov zaj dab neeg. Tsis zoo li cov thermosets, thermoplastic-impregnated roving tuaj yeem yaj thiab rov ua dua tshiab, qhib lub qhov rooj rau kev rov ua dua tshiab ntawm cov khoom siv tsheb thaum kawg ntawm lub voj voog lub neej ntawm lub tsheb. Ntxiv mus, lub zog xav tau los tsim cov fiberglass roving qis dua li ntawm txhuas lossis carbon fiber, txo cov "carbon embedded" ntawm lub tsheb txij li hnub thawj.

Kev Nkag Siab SEO rau Cov Thawj Coj Kev Yuav Khoom

Thaum muab khoomfiberglass rovingrau cov ntawv thov tsheb, nws tsis txaus los saib "tus nqi ib tuj." Cov pab pawg yuav khoom tam sim no tsom mus rau:

1.Lub zog Tensile (MPa):Xyuas kom meej tias cov fiber tuaj yeem tuav tau lub nra hnyav.

2.Kev Sib Haum Xeeb:Puas yog qhov roving ua haujlwm nrog cov txheej txheem resin tshwj xeeb (PA6, PP, lossis Epoxy)?

3.Kev sib xws:Puas yog qhov roving muab kev sib zog sib npaug thiab tsawg kawg nkaus fuzz, tiv thaiv kev poob haujlwm hauv cov kab ntau lawm tsis siv neeg?

Xaus lus

Yav tom ntej ntawm kev lag luam tsheb yuav sib dua, muaj zog dua, thiab ruaj khov dua. Thaum peb mus tob dua rau hauv kaum xyoo, kev koom ua ke ntawmfiberglass rovingrau hauv cov qauv thiab cov khoom siv ntawm lub tsheb yuav tsuas yog ua kom nrawm dua. Los ntawm kev hloov cov hlau hnyav nrog cov khoom sib xyaw ua haujlwm siab, cov chaw tsim khoom tsis yog tsuas yog tsim cov tsheb xwb; lawv tab tom tsim lub neej yav tom ntej ntawm kev txav mus los.
