Monga chinthu chofunikira chopepuka chamagalimotokusintha chitsulo ndi pulasitiki,FRP/zipangizo zophatikizikazimagwirizana kwambiri ndi kusunga mphamvu zamagalimoto, kuteteza chilengedwe ndi chitetezo. Kugwiritsa ntchito mapulasitiki olimbikitsidwa ndi ulusi wagalasi/zipangizo zopangira zinthu zosiyanasiyana popanga zipolopolo za thupi la magalimoto ndi zina zokhudzana nazo ndi njira imodzi yothandiza kwambiri yopangira magalimoto kukhala opepuka.
Kuyambira pamene galimoto yoyamba ya FRP padziko lonse, GM Corvette, inapangidwa bwino mu 1953, zinthu zopangidwa ndi FRP/composite zakhala mphamvu yatsopano mumakampani opanga magalimoto. Njira yachikhalidwe yokonzera magalimoto ndi yoyenera kupanga magalimoto ang'onoang'ono okha, ndipo siyingakwaniritse zosowa za chitukuko chopitilira chamakampani opanga magalimoto.
Kuyambira m'zaka za m'ma 1970, chifukwa cha chitukuko chopambana chaZipangizo za SMCndi kugwiritsa ntchito ukadaulo wopangira zinthu pogwiritsa ntchito makina komanso ukadaulo wopangira zinthu pogwiritsa ntchito makina, kuchuluka kwa zinthu zopangira zinthu za FRP/composite pachaka m'magalimoto kunafika pa 25%, zomwe zinakhala zoyamba pakupanga zinthu za FRP zamagalimoto. Nthawi ya chitukuko chachangu;
Pofika kumayambiriro kwa zaka za m'ma 1990 m'ma 1920, chifukwa cha kufunika kowonjezereka kwa chitetezo cha chilengedwe, kupepuka, komanso kusunga mphamvu, zinthu zopangidwa ndi thermoplastic zomwe zimayimiridwa ndiGMT (magalasi opangidwa ndi ulusi wolimbikitsidwa ndi thermoplastic composite material) ndi LFT (ma fiber opangidwa ndi thermoplastic composite material yaitali)Zapezeka. Zakula mofulumira, ndipo zimagwiritsidwa ntchito kwambiri popanga zida zamagalimoto, ndi kukula kwa pachaka kwa 10-15%, zomwe zimapangitsa kuti pakhale nthawi yachiwiri yokukula mwachangu. Monga patsogolo pa zipangizo zatsopano, zipangizo zophatikizika pang'onopang'ono zikulowa m'malo mwa zitsulo ndi zipangizo zina zachikhalidwe m'zigawo zamagalimoto, ndipo zakhala ndi zotsatira zabwino komanso zotetezeka.
Zigawo zamagalimoto za FRP/composite zimagawidwa m'magulu atatu:ziwalo za thupi, ziwalo za kapangidwe kake ndi ziwalo zogwirira ntchito.
1. Ziwalo za thupi:kuphatikizapo zipolopolo za thupi, denga lolimba, madenga a dzuwa, zitseko, ma radiator grilles, zowunikira magetsi, ma bumpers akutsogolo ndi kumbuyo, ndi zina zotero, komanso ziwalo zamkati. Iyi ndiyo njira yayikulu yogwiritsira ntchito FRP/zipangizo zophatikizika m'magalimoto, makamaka kuti zikwaniritse zosowa za kapangidwe kosavuta komanso mawonekedwe apamwamba. Pakadali pano, kuthekera kopanga ndi kugwiritsa ntchito kukadali kwakukulu. Makamaka mapulasitiki opangidwa ndi ulusi wagalasi olimbikitsidwa ndi thermosetting. Njira zodziwika bwino zopangira zinthu zimaphatikizapo: SMC/BMC, RTM ndi kuyika/kupopera ndi manja.
2. Zigawo za kapangidwe kake:kuphatikizapo mabulaketi akutsogolo, mafelemu a bumper, mafelemu a mipando, pansi, ndi zina zotero. Cholinga chake ndikukweza ufulu wa kapangidwe, kusinthasintha komanso kukhulupirika kwa ziwalozo. Gwiritsani ntchito makamaka SMC, GMT, LFT ndi zipangizo zina zamphamvu.
3.Zigawo zogwirira ntchito:Mbali yake yayikulu ndi yakuti imafuna kukana kutentha kwambiri komanso kukana dzimbiri kwa mafuta, makamaka pa injini ndi mbali zake zozungulira. Monga: chivundikiro cha valavu ya injini, manifold a intake, poto yamafuta, chivundikiro cha fyuluta ya mpweya, chivundikiro cha chipinda cha giya, chivundikiro cha mpweya, mbale yoteteza mapaipi a intake, tsamba la fan, mphete yotsogolera mpweya wa fan, chivundikiro cha heater, magawo a thanki yamadzi, chipolopolo cha Outlet, turbine ya pampu yamadzi, bolodi loteteza mawu a injini, ndi zina zotero. Zipangizo zazikulu zogwirira ntchito ndi izi: SMC/BMC, RTM, GMT ndi nayiloni yolimbikitsidwa ndi ulusi wagalasi.
4. Mbali zina zokhudzana nazo:monga masilinda a CNG, zida zaukhondo zamagalimoto apaulendo ndi ma RV, zida za njinga zamoto, mapanelo oletsa kuwala pamsewu waukulu ndi zipilala zoletsa kugundana, zipilala zodzipatula pamsewu waukulu, makabati a denga la galimoto yoyendera katundu, ndi zina zotero.
