Glass Mat Reinforced Thermoplastic (GMT) ndi buku, lopulumutsa mphamvu, lopepuka komanso lopepuka lopangidwa ndi thermoplastic resin ngati matrix ndi galasi fiber mat ngati mafupa olimbikitsidwa.Pakalipano ndi gulu lachitukuko lazinthu zambiri padziko lonse lapansi ndipo limatengedwa ngati chimodzi mwazinthu zatsopano zazaka za zana lino.
GMT imatha kupanga zinthu zomwe zatha.Kenako amakonzedwa mwachindunji muzopangidwa ndi mawonekedwe omwe akufuna.GMT ili ndi mawonekedwe apamwamba kwambiri, kukana kwamphamvu kwambiri, ndipo ndiyosavuta kusonkhanitsa ndikuwonjezera.Ndi yamtengo wapatali chifukwa cha mphamvu zake komanso kupepuka kwake, zomwe zimapangitsa kuti zikhale zofunikira kwambiri kuti zilowe m'malo mwazitsulo ndi kuchepetsa misa.
1. Ubwino wa Zida za GMT
1) Mphamvu yayikulu: Mphamvu ya GMT ndi yofanana ndi ya polyester yopangidwa ndi manja FRP, ndipo kachulukidwe kake ndi 1.01-1.19g/cm.Ndi yaying'ono kuposa thermosetting FRP (1.8-2.0g/cm), chifukwa chake, ili ndi mphamvu zapadera.
2) Zopepuka komanso zopulumutsa mphamvu: Kulemera kwa chitseko chagalimoto chopangidwa ndiZithunzi za GMTimatha kuchepetsedwa kuchokera ku 26 kg mpaka 15 kg, ndipo makulidwe ammbuyo amatha kuchepetsedwa kuti awonjezere malo agalimoto.Kugwiritsa ntchito mphamvu ndi 60% -80% yokha yazitsulo ndi 35% -50% yazitsulo zotayidwa.
3) Poyerekeza ndi thermosetting SMC (pawiri yopangira ma sheet), zinthu za GMT zili ndi maubwino ozungulira pang'ono, magwiridwe antchito abwino, kubwezeretsedwanso, komanso kusungirako kwakanthawi.
4) Kuchita kwamphamvu: Kutha kwa GMT kuyamwa kugwedezeka ndi 2.5-3 nthawi zambiri kuposa SMC.SMC, zitsulo, ndi aluminiyamu zonse zidawonongeka kapena kung'ambika, koma GMT idakhalabe yosavulazidwa.
5) Kukhazikika kwakukulu: GMT ili ndi nsalu ya GF, yomwe imatha kukhalabe ndi mawonekedwe ake ngakhale pali kukhudza kwa 10mph.
2. Kugwiritsa Ntchito Zipangizo za GMT M'gawo Lamagalimoto
Mapepala a GMT ali ndi mphamvu zambiri ndipo amatha kupangidwa kukhala zigawo zopepuka.Nthawi yomweyo, ili ndi ufulu wopanga, kugunda mwamphamvu kwamphamvu, komanso magwiridwe antchito abwino.Zakhala zikugwiritsidwa ntchito kwambiri mumakampani opanga magalimoto kuyambira 1990s.Pomwe zofunikira pazachuma chamafuta, kubwezeretsedwanso, komanso kusavuta kukonza zikupitilira kukula, msika wa zida za GMT zamagalimoto oyendetsa magalimoto ukupitilira kukula.
Pakali pano, zipangizo GMT chimagwiritsidwa ntchito makampani magalimoto, makamaka monga mipando mafelemu, bumpers, mapanelo zida, hoods, mabatire batire, zopondaponda, malekezero kutsogolo, pansi, fenders, zitseko zakumbuyo, madenga, katundu Zigawo monga bulaketi, dzuwa. ma visor, zotchingira matayala, etc.
1) Mpando chimango
Mzere wachiwiri wopangidwa ndi mpando wachiwiri pagalimoto ya Ford Motor Company ya 2015 Ford Mustang (chithunzi pansipa) idapangidwa ndi Tier 1 supplier/converter Continental Structural Plastics pogwiritsa ntchito Hanwha L&C's 45% unidirectional glass-reinforced fiberglass mat thermoplastic mat thermoplastic GMT) ndi Century Tool & Gage, compression molding.Imakwaniritsa bwino malamulo achitetezo aku Europe ovuta kwambiri a ECE pakusunga katundu.
Gawoli linkafuna kubwerezabwereza kwa 100 FEA kuti amalize, kuchotsa magawo asanu pamapangidwe achitsulo oyambirira.Ndipo imapulumutsa ma kilogalamu 3.1 pagalimoto imodzi mwanjira yocheperako, yomwe ndiyosavuta kuyiyika.
2) Kumbuyo kwa anti-kugunda mtengo
Mtengo wotsutsana ndi kugunda kumbuyo kwa Tucson yatsopano ya Hyundai (onani chithunzi pansipa) mu 2015 imapangidwa ndi zinthu za GMT.Poyerekeza ndi zida zachitsulo, mankhwalawa ndi opepuka komanso amakhala ndi zinthu zabwino zotsamira.Amachepetsa kulemera kwa galimoto ndi kugwiritsa ntchito mafuta pamene akuwonetsetsa kuti ntchito ikuyenda bwino.
3) Gawo lakutsogolo
Mercedes-Benz yasankha Quadrant Plastic Composites GMTex TM nsalu zolimbitsa ma thermoplastic composites monga zigawo zam'tsogolo mu S-Class yake (chithunzi pansipa) coupe yapamwamba.
4) Gulu loyang'anira pansi la thupi
Quadrant PlasticComposites imagwiritsa ntchito magwiridwe antchito apamwamba a GMTex TM poteteza hood pansi pa Mercedes Off-Road Special Edition.
5) Chimango cha mchira
Kuphatikiza pazabwino zanthawi zonse zophatikizika zogwirira ntchito komanso kuchepetsa kulemera, mawonekedwe a GMT tailgate amathandiziranso mawonekedwe azinthu osatheka ndi chitsulo kapena aluminiyamu.Imagwiritsidwa ntchito ku Nissan Murano, Infiniti FX45, ndi mitundu ina.
6) Dashboard chimango
GMT imapanga lingaliro latsopano la mafelemu a dashboard omwe amagwiritsidwa ntchito pamitundu ingapo ya Ford Group: Volvo S40 ndi V50, Mazda, ndi Ford C-Max.Ma composites awa amathandizira kuphatikizika kosiyanasiyana kogwira ntchito.Makamaka pophatikizira mamembala amtundu wagalimoto ngati machubu achitsulo opyapyala mukamawumba.Poyerekeza ndi njira zachikhalidwe, kulemera kumachepetsedwa kwambiri popanda kuonjezera mtengo.
