Izinto zangaphakathi ezitofotofo, iihoods ezibenyezelayo, ukugquma okothusayo...konke kubonisa ikratshi leemoto zemidlalo ebalaseleyo, ezibonakala zikude kubomi babantu abaqhelekileyo, kodwa uyazi?Ngapha koko, izinto zangaphakathi kunye neehood zezi moto zenziwe ngeemveliso zefiberglass.

Ukongeza kwiimoto eziphezulu, abantu abaninzi abaqhelekileyo baqhuba iimoto kunye neelori ezithutha iimpahla, zonke zenziwe nge-glass fiber.Kunokuthiwa ukusebenza kwesicelo sefiber yeglasi kunokwandiswa ngokungenasiphelo.

Okwangoku, i-glass fiber-reinforced i-automotive composite materials inokwahlulwa ibe ziindidi ezimbini: i-thermoplastic kunye ne-thermosetting.Iinkqubo zokuvelisa zombini zihlukile, kwaye ukusetyenziswa kwahlukile.Iimveliso zefayibha zeglasi ze-Thermosetting ze-LFT zisetyenziselwa ubukhulu becala kwiindawo zangaphakathi zeemoto, ezifana nezibiyeli zepaneli yesixhobo, iibhokisi zamatayara asecaleni, izibiyeli zangaphambili kunye nezinye iinxalenye zesakhelo se-auto;Thermoset SMC fiberglass iimveliso zisetyenziselwa ikakhulu iihoods zemoto, iibumpers, kunye nezahluli zeetanki zamafutha.Izigqubuthelo ze-Thermal kunye nezinye iindawo zesakhiwo semoto.
Ngophuhliso loshishino lweemoto kunye nokukhuthazwa kokugcinwa kwamandla kunye neengcamango zokukhusela indalo, iimoto ezilula ziye zaba yinto eqhelekileyo. Ukusetyenziswa kwamafutha emoto kuxhomekeke ekufudukeni kwe-injini kunye nobunzima obupheleleyo bemoto.Kwisiseko sokugcina umgangatho jikelele, ukusebenza kunye neendleko zemoto, ukunciphisa ubunzima bemoto kunokunyusa ngokufanelekileyo amandla okuvelisa kunye nokuphatha, ukunciphisa ukusetyenziswa kwepetroli, kunye nokunciphisa ukukhutshwa kokukhutshwa.Uphononongo lubonise ukuba yonke i-10% yokunciphisa ubunzima bezithuthi, ukusetyenziswa kwepetroli kunokuncitshiswa nge-6-8%.Ukutshintsha intsimbi yemveli ngefiber yeglasi kunokunciphisa kakhulu ubunzima bemoto.

Iimveliso ze-SMC ziyinxalenye ebalulekileyo yamalungu emoto.Indlela yokunciphisa ubunzima beemoto ngokuphucula ukusebenza kwayo ngumba ongxamisekileyo ukuba abenzi beemoto bawusombulule.
Okwangoku, eyona ndlela iyaziwayo kwishishini kukutshintsha iifayili zemveli kunye neentsimbi zeglasi ezingenanto, ngaloo ndlela ukunciphisa ubuninzi bephepha, ukufezekisa umphumo wokunciphisa ubunzima bemoto.Kodwa ingxaki oku kuzisa kukuba iipropathi zoomatshini zezinto nazo ziyancipha.Ngoko ke, ukwenzela ukuba kuqinisekiswe iipropati zomatshini phantsi kweemeko eziphantsi, iifayili zeglasi zingasetyenziselwa ukubonelela ngeemeko eziphezulu zoomatshini.Iimveliso ze-SMC ezikhankanywe ngasentla zenziwe ngefiber yeglasi, i-fiber kunye ne-resin.
Iimveliso zeglasi zefayibha ze-SMC ezinamandla aphezulu kunye neempawu zomhlaba.Imveliso inokuhlangabezana neemfuno zeempawu zemishini kunye ne-A-level surface properties ngexesha elifanayo, kwaye ifanelekile ukuveliswa kweengxenye zembonakalo yemoto kunye neengxenye zesakhiwo.Xa kuthelekiswa nabakhuphisana namashishini phantsi kweemeko ezifanayo, ukusebenza komatshini jikelele kuye kwanda nge-20%, ebonelela ngesisombululo kwingxaki ye-sMC-low-density mechanical performance degradation.
Njengazo iimoto zemidlalo ezinqwenelekayo, iimfuno zamandla kunye nenkangeleko ziphezulu kakhulu kuneemoto eziqhelekileyo, ngakumbi imbonakalo kunye nokuguda.I-SMC isebenzisa ifayibha yeglasi engu-456 njengodidi olutsha lwemveliso yeglasi yefayibha kumalungu emoto, anokudibana nomgangatho we-A womthengi, oko kukuthi, iimfuno zomphezulu wesipili, kunye nokukhanya kwayo kwanele ukuhambelana nokuma kweemoto ezinkulu.

Ukongeza kwiimveliso ze-SMC, i-glass fiber-reinforced thermoplastic materials inokudlala indima ebalulekileyo kwintsimi yokutshintsha intsimbi ngeplastiki kwiimoto.Umsonto we-LFT osebenza kakhulu ongu-362H usetyenziswa ikakhulu kwiindawo zemoto ezifana nezipili ezibonisa ngasemva, izigqubuthelo ezithintela isandi, izibiyeli zepaneli yesixhobo, njl.
Itekhnoloji ye-LFT ineemfuno eziphezulu zokusetyenzwa komsonto, ngakumbi ukuxhathisa ukunxiba komsonto.Ubunwele ngekhilogram ye-362H buphantsi kakhulu.UGqr. Fan Jiashu weZiko leR&D leMveliso ukuqinisekisile oku ngokuthelekisa umfuniselo.Xa ebeka ukufuma ukuya kwi-50%, ubunwele ngekhilogram ye-362H buphantsi kakhulu kunoko kwemveliso yokuthelekisa;xa umswakama ukhuphuka ukuya kuma-75%, ukunyuka kweenwele kuzo zonke iimveliso kukhula, okugqitywa yimpawu ze-agent yokulinganisa intambo ngokwayo.Kodwa into emangalisayo kukuba xa umswakama ungama-75%, ubunwele be-362H busephantsi kuneqela lokulawula, elibonisa ukuxhathisa kwe-abrasion ye-362H.
Akunjalo kuphela, iipropathi zemishini ye-362H nazo zinamandla aphezulu kunye nokuqina okuphezulu.Ngayo, imoto iya kukwazi ukumelana neengozi xa kwenzeka impembelelo enzima.Ayiyi kuba "i-brittle" njengentsimbi, kwaye ayiyi kuba lula "yenzakala".Oku kuyafana nomphezulu we-362H.Unyango olulodwa lwe-ejenti yokulinganisa ayinakwahlulwa.Ukuphuhliswa kokusebenza okuphezulu kunye nokusebenza okuphezulu kwe-LFT-intambo echanekileyo yokuphucula i-PP 362H iphucula ngakumbi inkqubo yemveliso yentambo ngqo ye-LFT.Ukusasazwa kwayo okuphezulu kunye nokuthambisa okuphezulu kuyahlangabezana neemfuno zomthengi zokuqhubekeka.
