Magalasi owonjezera a thermoplastic (otchedwa GMT) amatanthawuza zinthu zophatikizika, zopulumutsa mphamvu komanso zopepuka zokhala ndi utomoni wa thermoplastic ngati matrix ndi magalasi fiber mat ngati chigoba cholimbitsidwa;GMT ili ndi ntchito zovuta kupanga, ndipo kukana Kwabwino Kwambiri, ngakhale kukhala kosavuta kusonkhanitsa ndi kukonzanso, nthawi zambiri kumapanga mapepala omaliza, omwe amatha kusinthidwa mwachindunji kukhala mawonekedwe omwe mukufuna.
一,Ubwino wa zida za GMT
1. Mphamvu zapamwamba
Mphamvu za GMT ndizofanana ndi zopangidwa ndi polyester yoyika manja pa FRP, kachulukidwe kake ndi 1.01-1.19g/cm, ndipo ndi yaying'ono kuposa thermosetting FRP (1.8-2.0g/cm), kotero ili ndi mphamvu zambiri.
2. Kukhazikika kwakukulu
GMT ili ndi nsalu ya GF kotero imasunga mawonekedwe ake ngakhale itawonongeka ndi 10mph.
3. Zopepuka komanso zopulumutsa mphamvu
Kulemera kwa chitseko cha galimoto chopangidwa ndi zinthu za GMT kumatha kuchepetsedwa kuchokera ku 26Kg kufika ku 15Kg, ndipo makulidwe a kumbuyo amatha kuchepetsedwa, kotero kuti malo a galimoto akhoza kuwonjezeka, komanso kugwiritsa ntchito mphamvu ndi 60% -80% yokha. zitsulo zopangidwa ndi zitsulo ndi 35% -50% za aluminiyamu.
4. Kuchita bwino
Kuthekera kwa GMT kuyamwa kugwedezeka ndikokwera 2.5-3 kuposa kwa SMC.Pansi pa mphamvu yamphamvu, madontho kapena ming'alu amawonekera mu SMC, chitsulo ndi aluminiyamu, koma GMT ndi yotetezeka.Ili ndi ubwino wobwezeretsanso komanso nthawi yayitali yosungirako.
二,Kugwiritsa ntchito zida za GMT m'munda wamagalimoto
Tsamba la GMT liri ndi mphamvu zambiri ndipo limatha kupangidwa kukhala magawo opepuka, ndipo nthawi yomweyo lili ndi ufulu wodzipangira, kuyamwa kwamphamvu kwamphamvu, komanso magwiridwe antchito abwino.Msika wa zida za GMT zamagalimoto oyendetsa magalimoto upitilira kukula pang'onopang'ono pomwe zofunikira pakuchulukira kwamafuta, kubwezanso komanso kusavuta kukonza zikupitilira kukula.
Pakadali pano, zida za GMT zimagwiritsidwa ntchito kwambiri pamafakitale amagalimoto, makamaka kuphatikiza mafelemu a mipando, mabampu, ma dashboards, ma hoods, mabatani a batire, zopondaponda, zomangira zakutsogolo, pansi, zotchingira, zitseko zakumbuyo, madenga, Mabulaketi akatundu, zowonera dzuwa, tayala lopatula. ma racks, etc.
Kugwiritsa ntchito kwa GMT pamagalimoto kumaphatikizapo:
1. Mpando Frame
Mpando wachiwiri kumbuyo kwa Ford Motor Company 2015 Ford Mustang Roadster adapangidwa ndi Tier 1 supplier/fabricator Continental Structural Plastics pogwiritsa ntchito Hanwha L&C's 45% unidirectional glass fiber reinforced fiberglass mat thermoplastic thermoplastic composite & Century Tooling (GMT) , kuponderezedwa, kukwanitsa kukwaniritsa malamulo ovuta kwambiri a chitetezo ku Ulaya a ECE onyamula katundu.
2. Mtsinje wakumbuyo wotsutsa kugunda
Mtengo wotsutsa kugunda kumbuyo kwa Tucson yatsopano ya Hyundai ya 2015 ndi zinthu zomwe GMT imagwiritsidwa ntchito.Poyerekeza ndi zitsulo zopangidwa ndi zitsulo, zimakhala zopepuka komanso zimakhala ndi ntchito yabwino yotsamira.Amachepetsa kulemera kwa galimoto ndi kugwiritsa ntchito mafuta pamene akuonetsetsa kuti chitetezo chikugwira ntchito.
3. Gawo lakutsogolo
Mercedes-Benz yasankha Quadrant Plastic Composites GMTex TM nsalu zolimbitsa ma thermoplastic composites monga zinthu zakutsogolo zam'mbuyo mumpikisano wake wapamwamba wa S-Class.
4. Thupi lotetezedwa
Chitetezo cha underbody hood chopangidwa ndi Quadrant Plastic Composites mu GMTex TM yochita bwino kwambiri chimayikidwa pamtundu wapadera wa Mercedes off-road.
5. Mafupa a Tailgate
Kuphatikiza pa ubwino wanthawi zonse wa kugwirizanitsa ntchito ndi kuchepetsa kulemera, mawonekedwe a GMT tailgate amathandizira kuti GMT ipangidwe kuti ikwaniritse mawonekedwe azinthu zomwe sizingatheke ndi chitsulo kapena aluminiyamu, ndipo amagwiritsidwa ntchito mu Nissan Murano, Infiniti FX45 ndi zitsanzo zina.
6. Dashboard Framework
Lingaliro latsopano la GMT lopanga mafelemu a dashboard likugwiritsidwa ntchito kale pamitundu ingapo ya Ford Group.Zida zophatikizikazi zimathandizira kuphatikizika kosiyanasiyana kogwira ntchito, makamaka pophatikiza crossmember yagalimoto mu mawonekedwe a chubu chochepa kwambiri chachitsulo mu gawo lowumbidwa, komanso ndi chikhalidwe Poyerekeza ndi njirayo, kulemera kumachepetsedwa kwambiri popanda kuwonjezera mtengo.
GMT imayamikiridwa kwambiri chifukwa cha mphamvu zake komanso kupepuka kwake, ndikupangitsa kuti ikhale gawo loyenera lopanga m'malo mwachitsulo ndikuchepetsa misa.Pakalipano ndi gulu lachitukuko lazinthu zambiri padziko lonse lapansi ndipo limatengedwa ngati chimodzi mwazinthu zatsopano zazaka za zana lino.
