Iav Mat Reinforced Thermoplastic (GMT) yog ib qho tshiab, txuag hluav taws xob, cov khoom siv sib xyaw nrog cov thermoplastic resin li matrix thiab iav fiber lev raws li lub cev pob txha.Tam sim no nws yog ib qho khoom siv sib xyaw ua ke tsim ntau yam hauv ntiaj teb thiab suav tias yog ib qho ntawm cov ntaub ntawv tshiab ntawm lub xyoo pua.
GMT feem ntau tuaj yeem tsim cov ntawv semi-tiav khoom.Nws yog tom qab ntawd ncaj qha ua tiav rau hauv cov khoom ntawm qhov xav tau.GMT muaj cov qauv tsim qauv zoo, muaj kev cuam tshuam zoo heev, thiab yooj yim rau kev sib sau thiab ntxiv.Nws yog khoom plig rau nws lub zog thiab lub teeb, ua rau nws yog qhov zoo tshaj plaws cov qauv siv los hloov cov hlau thiab txo qhov loj.
1. Qhov zoo ntawm GMT cov ntaub ntawv
1) Lub zog siab: Lub zog ntawm GMT zoo ib yam li cov khoom siv tes ua polyester FRP, thiab nws qhov ceev yog 1.01-1.19g / cm3.Nws yog me dua thermosetting FRP (1.8-2.0g / cm), yog li, nws muaj lub zog tshwj xeeb dua.
2) Lub teeb yuag thiab txuag hluav taws xob: Qhov hnyav ntawm lub qhov rooj tsheb ua los ntawmGMT cov ntaub ntawvtuaj yeem raug txo los ntawm 26 kg mus rau 15 kg, thiab lub thickness ntawm lub nraub qaum tuaj yeem txo kom nce qhov chaw tsheb.Kev siv hluav taws xob tsuas yog 60% -80% ntawm cov khoom siv hlau thiab 35% -50% ntawm cov khoom siv txhuas.
3) Muab piv nrog cov thermosetting SMC (cov ntawv molding compound), GMT cov khoom muaj qhov zoo ntawm lub voj voog molding luv, kev ua haujlwm zoo, rov ua dua, thiab lub voj voog ntev.
4) Kev cuam tshuam kev ua haujlwm: GMT lub peev xwm los nqus kev poob siab yog 2.5-3 zaug siab dua SMC.SMC, hlau, thiab txhuas txhua tus raug kev puas tsuaj los yog tawg nyob rau hauv kev cuam tshuam, tab sis GMT tseem tsis tau raug mob.
5) High rigidity: GMT muaj GF ntaub, uas tseem tuaj yeem tswj nws cov duab txawm tias muaj kev cuam tshuam ntawm 10mph.
2. Kev siv cov khoom siv GMT hauv Automotive Field
GMT cov ntawv muaj lub zog siab thiab tuaj yeem ua rau cov khoom sib sib zog nqus.Nyob rau tib lub sijhawm, nws muaj kev ywj pheej tsim siab, muaj zog sib tsoo lub zog nqus, thiab kev ua haujlwm zoo.Nws tau siv dav hauv kev lag luam tsheb txij li xyoo 1990.Raws li cov kev xav tau rau kev lag luam roj, kev rov ua dua tshiab, thiab kev ua kom yooj yim txuas ntxiv mus ntxiv, kev ua lag luam rau GMT cov ntaub ntawv rau kev lag luam tsheb yuav loj hlob tsis tu ncua.
Tam sim no, GMT cov ntaub ntawv tau siv dav hauv kev lag luam tsheb, feem ntau suav nrog lub rooj zaum ncej, bumpers, instrument panels, hoods, roj teeb brackets, ko taw pedals, pem hauv ntej kawg, pem teb, fenders, rear qhov rooj, lub ru tsev, lub hnab ntim khoom xws li brackets, hnub visors, spare tire racks, thiab lwm yam.
1) Rooj ncej
Qhov thib ob-kab seatback compression-molded tsim ntawm Ford Motor Company lub xyoo 2015 Ford Mustang (daim duab hauv qab) kev ua si tsheb yog tsim los ntawm Tier 1 tus neeg muag khoom / converter Continental Structural Plastics siv Hanwha L&C's 45% unidirectional iav-reinforced fiberglass lev thermoplastic Moulds rau cov ntaub ntawv sib xyaw ( GMT) thiab Century Tool & Gage, compression molding.Nws ua tiav raws li qhov nyuaj heev European kev ruaj ntseg cov cai ECE rau kev tswj lub hnab nqa khoom.
Ib feem yuav tsum tau ntau tshaj 100 FEA iterations kom tiav, tshem tawm tsib ntu los ntawm cov qauv hlau ua ntej.Thiab nws txuag 3.1 kilograms ib lub tsheb nyob rau hauv ib tug nyias muaj nyias qauv, uas yog tseem yooj yim rau nruab.
2) rear anti-kev sib tsoo beam
Lub teeb tiv thaiv kev sib tsoo nyob tom qab ntawm Hyundai Tucson tshiab (saib daim duab hauv qab no) hauv 2015 yog ua los ntawm GMT cov khoom.Piv nrog rau cov ntaub ntawv steel, cov khoom yog sib dua thiab muaj zog cushioning zoo dua.Nws txo cov tsheb hnyav thiab roj noj thaum ua kom muaj kev nyab xeeb.
3) Pem hauv ntej-kawg module
Mercedes-Benz tau xaiv Quadrant Plastic Composites GMTexTM fabric-reinforced thermoplastic composites li front-end module element in its S-Class (pictured below) khoom kim heev coupe.
4) Lub cev qis tiv thaiv vaj huam sib luag
Quadrant PlasticComposites siv cov kev ua tau zoo GMTex TM rau hauv qab hood tiv thaiv rau Mercedes Off-Road Special Edition.
5) Tailgate ncej
Ntxiv rau qhov zoo li niaj zaus ntawm kev sib koom ua ke thiab txo qhov hnyav, kev tsim ntawm GMT tailgate cov qauv kuj tseem ua rau cov khoom siv tsis tuaj yeem nrog hlau lossis txhuas.Siv rau Nissan Murano, Infiniti FX45, thiab lwm yam qauv.
6) Dashboard moj khaum
GMT tsim lub tswv yim tshiab ntawm dashboard thav duab npaj rau siv rau ntau yam Ford Group qauv: Volvo S40 thiab V50, Mazda, thiab Ford C-Max.Cov composites no ua rau muaj ntau yam kev sib koom ua ke.Tshwj xeeb tshaj yog los ntawm kev koom ua ke lub tsheb hla cov tswv cuab nyob rau hauv daim ntawv ntawm nyias steel hlab nyob rau hauv molding.Piv nrog rau cov txheej txheem ib txwm muaj, qhov hnyav tau txo qis yam tsis tau nce tus nqi.
