Monga zofunika opepuka zakuthupi kwamagalimotokusintha zitsulo ndi pulasitiki,FRP/zophatikizikazimagwirizana kwambiri ndi kupulumutsa mphamvu zamagalimoto, kuteteza chilengedwe ndi chitetezo.Kugwiritsa ntchito mapulasitiki olimbitsa magalasi / zida zophatikizika kupanga zipolopolo zamagalimoto ndi ziwalo zina zofananira ndi njira imodzi yothandiza kwambiri yopangira magalimoto kukhala opepuka.
Popeza galimoto yoyamba ya FRP padziko lonse lapansi, GM Corvette, idapangidwa bwino mu 1953, zida za FRP / zophatikizika zakhala mphamvu yatsopano mumakampani amagalimoto.Njira yachikhalidwe yokhazikitsira manja ndiyoyenera kupanga zinthu zazing'ono, ndipo sizingakwaniritse zosowa zamakampani opanga magalimoto.
Kuyambira mu 1970s, chifukwa cha bwino chitukuko chaZithunzi za SMCndi kugwiritsa ntchito makina akamaumba luso ndi mu nkhungu ❖ kuyanika luso, mlingo wa pachaka wa FRP/zophatikizika zipangizo mu ntchito magalimoto anafika 25%, kukhala woyamba pa chitukuko cha magalimoto FRP mankhwala.Nthawi yachitukuko chofulumira;
Pofika kumayambiriro kwa zaka za m'ma 1990 m'ma 1920, ndi kufunikira kowonjezereka kwa chitetezo cha chilengedwe, kupepuka, ndi kupulumutsa mphamvu, zipangizo zopangira thermoplastic zoyimiridwa ndiGMT (magalasi opangidwa ndi fiber mat amalimbitsa ma thermoplastic composite material) ndi LFT (zautali wautali wolimbitsa thermoplastic composite material)anapezedwa.Idakula mwachangu, ndipo imagwiritsidwa ntchito makamaka popanga zida zamagalimoto zamagalimoto, ndikukula kwapachaka kwa 10-15%, ndikuyambitsa nthawi yachiwiri yachitukuko chofulumira.Monga kutsogolo kwa zida zatsopano, zida zophatikizika zimasintha pang'onopang'ono zinthu zachitsulo ndi zida zina zamagalimoto, ndipo zapeza zotsatira zachuma komanso zotetezeka.
Zigawo zamagalimoto za FRP/composite zimagawidwa m'magulu atatu:ziwalo za thupi, zomangika ndi ziwalo zogwirira ntchito.
1. Ziwalo za thupi:kuphatikizapo zipolopolo za thupi, madenga olimba, denga la dzuwa, zitseko, magalasi a radiator, zowonetsera magetsi, kutsogolo ndi kumbuyo kumbuyo, ndi zina zotero, komanso mbali zamkati.Uwu ndiye njira yayikulu yogwiritsira ntchito zida za FRP/zophatikizika pamagalimoto, makamaka kuti zikwaniritse zosowa zamapangidwe osavuta komanso mawonekedwe apamwamba kwambiri.Pakali pano, kuthekera kwa chitukuko ndi ntchito akadali aakulu.Makamaka ulusi wagalasi umalimbitsa mapulasitiki a thermosetting.Njira zopangira zodziwikiratu ndi izi: SMC/BMC, RTM ndi kuyika mmwamba/kutsitsi.
2. Zigawo zamapangidwe:kuphatikiza mabulaketi akutsogolo, mafelemu okulirapo, mafelemu amipando, pansi, ndi zina zambiri. Cholinga ndikukweza ufulu wamapangidwe, kusinthasintha komanso kukhulupirika kwa magawo.Gwiritsani ntchito kwambiri mphamvu za SMC, GMT, LFT ndi zipangizo zina.
3.Zigawo zogwirira ntchito:Mbali yake yaikulu ndi yakuti imafunika kukana kutentha kwakukulu ndi kukana kwa dzimbiri la mafuta, makamaka kwa injini ndi mbali zake zozungulira.Monga: chivundikiro cha valve ya injini, zochulukirachulukira, poto yamafuta, chivundikiro cha fyuluta ya mpweya, chivundikiro cha chipinda cha giya, chivundikiro cha mpweya, mbale yolondera ya chitoliro, tsamba la fani, mphete yowongolera mpweya, chivundikiro cha heater, mbali za thanki yamadzi, chipolopolo cha Outlet, turbine yamadzi. , injini phokoso kutchinjiriza bolodi, etc. waukulu ndondomeko zipangizo ndi: SMC/BMC, RTM, GMT ndi galasi CHIKWANGWANI analimbitsa nayiloni.
4. Zina zofananira:monga masilinda a CNG, magalimoto onyamula anthu ndi zida zaukhondo za RV, mbali za njinga zamoto, mapanelo odana ndi glare ndi zipilala zolimbana ndi kugundana, ma piers odzipatula amisewu, makabati oyendera padenga lagalimoto, ndi zina zambiri.
