Dab tsi yog cov ntawv thov ntawm fiberglass tws strand lev, cov khoom siv tseem ceeb rau tsheb sib tsoo?

Hauv kev lag luam automotive niaj hnub no, uas tau nrawm nws txoj kev hloov pauv mus rau kev txuag hluav taws xob, kev tiv thaiv ib puag ncig, kev nyab xeeb, thiab kev ua haujlwm zoo, lub teeb yuag tsis yog ib qho kev xaiv xwb, tab sis yog txoj hauv kev tseem ceeb rau cov neeg tsim khoom los txhim kho kev sib tw, ua tau raws li kev cai tswj hwm, thiab txo kev siv hluav taws xob. Los ntawm kev txo qhov hnyav thiab kev siv roj hauv cov tsheb siv roj rau kev txhim kho ntau yam thiab kev ua kom zoo ntawm cov tsheb tshiab, cov cuab yeej siv hluav taws xob sib zog ua rau tag nrho cov qauv tsim, R & D, thiab cov saw hlau ntau lawm. Ntawm cov khoom siv hnyav hnyav,chopped strand lev(CSM) tau dhau los ua ib qho tseem ceeb hauv substrate nyob rau hauv daim teb ntawm automotive composite cov ntaub ntawv vim nws kev ua tau zoo heev, ruaj khov zoo, thiab tus nqi siab -effectiveness.

 

I. Vim li cas automotive lightweighting inseparable ntawm iav fiber ntau cov ntaub ntawv?

 

Lub hauv paus ntsiab lus ntawm kev siv lub tsheb sib tsoo yog qhov yooj yim: kom txo lub tsheb hnyav kom ntau li ntau tau thaum ua kom muaj zog thiab kev nyab xeeb. Cov ntaub ntawv qhia tau hais tias rau txhua txhua 10% txo cov tsheb hnyav, kev siv hluav taws xob tuaj yeem txo tau los ntawm 6% mus rau 8%, qhov ntau ntawm lub zog tshiab tuaj yeem nce ntxiv los ntawm 5% mus rau 10%, thiab kev ncua kev ncua luv luv thiab tuav tau zoo dua.

 

Muaj peb txoj hauv kev tseem ceeb kom ua tiav qhov hnyav: kev ua kom zoo ntawm cov qauv, kev tsim khoom siab heev, thiab kev siv cov khoom siv tshiab. Ntawm cov no, kev hloov khoom siv yog qhov ncaj qha thiab nrawm tshaj plaws kom ua tiav cov txiaj ntsig.

 

Traditional steel has high density and is difficult to mold, while aluminum alloys and magnesium alloys are expensive, and carbon fiber, although possessing top-tier performance, is too pricey to be widely adopted. Cov iav fiber ntau, txawm li cas los xij, zoo kawg nkaus sib npaug kev ua tau zoo, tus nqi, thiab kev ua tiav, muaj cov txiaj ntsig hauv qab no:

 

- Tsawg ceev, muaj zog tshwj xeeb, thiab txo qhov hnyav;

- Kev tiv thaiv corrosion, kev laus ua haujlwm, thiab kev ua haujlwm ntev;

- Saj zawg zog molding, muaj peev xwm ntawm integrally molding complex qhov chaw;

- Ntau cov ntaub ntawv raw, tus nqi siab-kev ua tau zoo, haum rau loj- nplai ntau lawm.

 

Ntawm cov khoom siv iav fiber ntau, chopped strand lev (CSM) tau dhau los ua cov khoom siv tseem ceeb rau kev siv lub tsheb vim nws zoo heev uniformity, impregnation ceev, seem stability, thiab balanced mechanical zog.

 

II. Dab tsi yog chopped strand lev (CSM), thiab nws qhov zoo yog dab tsi?

 

Choped strand lev (CSM) yog ib daim ntawv-xws li cov khoom siv txhawb zog los ntawm kev txiav alkali-dawb iav fiber ntau filaments rau hauv qee qhov ntev, sib npaug sib npaug ntawm qhov tsis yog - kev taw qhia, thiab khi lawv nrog cov tshuaj binder. Nws yog ib qho ntawm cov khoom siv feem ntau siv rau fiberglass reinforced plastics (FRP) thiab cov ntaub ntawv sib xyaw. Hauv kev siv tsheb, nws cov txiaj ntsig tseem ceeb yog qhov zoo tshaj:

 

1. Sib npaug Mechanical Properties: Cov iav fiber ntau tsis yog - kev taw qhia kev faib ua kom muaj kev ntxhov siab zoo ib yam, ua rau cov khoom muaj kev cuam tshuam zoo heev, khoov, thiab qaug zog, ua tau raws li qhov yuav tsum tau muaj lub zog ntawm cov qauv tsheb thiab lub cev.

 

2. Fast Impregnation thiab High Production Efficiency: Cov kev xav tau nruab nrab bulkiness thiab zoo compatibility nrog polyester, epoxy resins, thiab lwm yam., tso cai rau kom ceev impregnation nrog ob peb pa npuas. Nws yog tsim rau ntau yam txheej txheem xws li molding, tes nteg-up, thiab txhaj tshuaj molding, thiab yog zoo - haum rau automotive sib dhos kab ntau lawm.

 

3. High Surface Smoothness: Cov khoom tiav lawm muaj ib tug du nto yam tsis muaj kev ntxhib los mos, tso cai rau kev pleev xim ncaj qha, txheej, thiab lwm yam kev tshaj tawm - ua, ua rau lub ntsej muag zoo.

 

4. Dimensional Stability thiab Resistance to Deformation: Qhov loj me me hloov pauv tshwm sim nyob rau hauv qhov kub thiab txias, tsis tshua muaj kub, thiab cov av noo siab, kom ntseeg tau tias cov khoom siv hauv tsheb tsis txhob sib tsoo lossis tawg thaum lub sij hawm siv ntev -.

 

5. Tus nqi zoo heev-Kev ua tau zoo: Piv nrog kev xav tsis tu ncua, kev sib xyaw ua ke, thiab cov pa roj carbon fiber ntau, cov hlua khi hlua khi tau tus nqi qis dua thiab yooj yim dua los ntsuas, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov neeg tsim tsheb nrhiav kev txo nqi thiab txhim kho kev ua haujlwm.

 

III. Core Application Scenarios ntawm Fiberglass Chopped Strand Mat hauv Tsheb

 

Nrog rau kev siv cov ntaub ntawv sib xyaw ua ke hauv tsheb, daim ntawv thov fiberglass chopped strand lev (CSM) tau nthuav dav los ntawm cov khoom siv sab hauv thiab sab nrauv rau cov khoom siv ua haujlwm, npog ntau yam xws li cov neeg caij tsheb, tsheb lag luam, thiab lub zog tshiab.

 

1. Automotive Sab hauv thiab sab nrauv Trim Cheebtsam

 

Qhov no yog ib qho ntawm feem ntau paub tab thiab dav siv rau CSM.

 

- Lub qhov rooj trim panels, ncej guards, dashboard thav ntawv;

 

- Lub rooj zaum rov qab, lub hnub visors, lub hau npog, cov log tsheb seem;

 

- Lub cav hood npog, roj teeb npog, ntau yam npog npog.

 

Siv fiberglass chopped strand lev cov ntaub ntawv sib xyaw tuaj yeem ua tiav qhov hnyav ntawm 20% ~ 40%, thaum muab lub suab zoo dua, rwb thaiv tsev kub, thiab kev poob siab, yog li txhim kho kev tsav tsheb.

 

2. Lub Cev Vaj Huam Sib Luag thiab Cov Txheej Txheem Txheej Txheem

 

Txiav-strand xav yog sib npaug rau cov cheeb tsam uas xav tau ntau zog thiab rigidity:

 

- Pem hauv ntej thiab nram qab bumper ncej, spoiler, fairings;

 

- Fenders, hood panels, roj teeb pob hauv qab vaj huam sib luag;

 

- Cab ru tsev, sab vaj huam sib luag, av nkos, thiab lwm yam, rau kev lag luam tsheb.

 

Cov khoom sib xyaw ua ke muaj kev cuam tshuam -tiv taus, khawb- tiv taus, thiab xeb- tiv taus, ua rau txo nqi kho tom qab kev sib tsoo thiab lub neej siab dua- lub voj voog tus nqi.

 

3. Cov Ntsiab Lus Tseem Ceeb rau Cov Tsheb Hluav Taws Xob Tshiab

 

Lub zog tshiab tsheb muaj qhov xav tau ceev dua rau lub teeb yuag, ua rau muaj kev loj hlob tawg hauv fiberglass chopped strand lev:

 

- Lub zog roj teeb ntim cov tsev nyob, npog, daim hlau tiv thaiv;

 

- Rwb thaiv tsev thiab hluav taws xob rwb thaiv tsev rau cov motors thiab hluav taws xob tswj tshuab;

 

- Cov chaw nres nkoj them, siab -voltage tivthaiv npog.

 

Cov ntaub ntawv fiberglass tsis yog -conductive, tshav kub-insulating, nplaim taws-retardant, thiab siab- lub zog, zoo txhim kho cov roj teeb pob kev nyab xeeb thiab kev ntseeg siab, ua rau lawv yog ib qho kev xaiv zoo tshaj plaws rau kev siv lub zog tshiab.

 

4. Automotive Chassis thiab cov khoom siv ua haujlwm

 

Nyob rau hauv cov cheeb tsam uas complex thiab xav tau chassis ib puag ncig:

 

- Chassis underbody panels, tshav kub tiv thaiv, tso cov yeeb nkab cua sov rwb thaiv tsev;

 

- Ntxuam hniav, cua lim vaj tse, cov khoom siv yeeb nkab, thiab lwm yam.

 

Chopted strand lev (CSM) cov khoom uas tiv taus qhov kub thiab txias, corrosion, thiab kev laus, tso cai rau kev ua haujlwm ntev - lub sij hawm ruaj khov thiab txuas ntxiv kev ua neej ntev.

 

IV. Yav Tom Ntej Trends: CSM Yuav Txuas Ntxiv Ntxiv Rau Nws Lub Luag Haujlwm hauv Automotive Lightweighting

 

Nyob rau hauv lub xyoo tom ntej, kev lag luam tsheb yuav pom peb txoj kev loj hlob ncaj qha rau txoj kev loj hlob ntawm CSM:

 

1. Kev nkag mus ntawm cov tsheb tshiab lub zog txuas ntxiv mus ntxiv, ua rau muaj kev xav tau ntawm cov khoom siv sib xyaw rau cov roj teeb thiab cov khoom siv lub cev;

 

2. Kev nruj dua ib puag ncig thiab kev siv hluav taws xob rau tsheb yog ua kom lub teeb yuag ib qho qauv;

 

3. Cov txheej txheem tsim khoom sib xyaw ua ke tau hloov kho tas li, nrog rau kev siv dav dav ntawm cov kab ntau lawm xws li molding, RTM, thiab winding, uas ua rau muaj kev ua haujlwm siab dua thiab qis dua rau CSM. Lub caij no, nrog kev nthuav qhia tas mus li ntawm cov khoom tshiab xws li siab - kev ua tau zoo adhesives, ultrafine iav fibers, qis -fuzz, thiab siab -permeability tws strand lev, iav fiber ntau tws strand lev yuav tau upgraded rau siab zog, qis ntom, ntau dua ib puag ncig kev phooj ywg rau automation, thiab zoo dua cov khoom siv hlau. siab - nqi sib tw alloys. Los ntawm cov tsheb roj av mus rau lub zog tshiab tsheb, los ntawm cov cuab yeej thauj mus los mus rau qhov chaw ntse mobile, txhua qhov kev txhim kho hauv kev lag luam tsheb yog sib cais los ntawm cov khoom siv tshiab.
