I-Glass Mat Reinforced Thermoplastic (GMT) yinto entsha, eyonga amandla, nekhaphukhaphu edityanisiweyo ene-thermoplastic resin njenge-matrix kunye ne-glass fiber mat njenge-skeleton eqinisiweyo. Okwangoku luhlobo olusebenzayo kakhulu lophuhliso lwezinto ezidityanisiweyo kwihlabathi liphela kwaye luthathwa njengenye yezinto ezintsha zenkulungwane.
I-GMT ngokubanzi inokuvelisa iimveliso ezigqityiweyo ngamaphepha. Emva koko icutshungulwa ngqo ibe yimveliso yesimo esifunekayo. I-GMT ineempawu zoyilo ezintsonkothileyo, ukumelana okugqwesileyo kwempembelelo, kwaye kulula ukuyihlanganisa nokuyidibanisa. Ixabiswa ngamandla ayo kunye nokukhanya kwayo, okwenza ukuba ibe yinxalenye efanelekileyo yokwakha endaweni yentsimbi kunye nokunciphisa ubunzima.
1. Iingenelo zezixhobo ze-GMT
1) Amandla aphezulu: Amandla e-GMT afana nalawo eemveliso ze-polyester FRP ezibekwe ngesandla, kwaye uxinano lwayo yi-1.01-1.19g/cm. Incinci kune-thermosetting FRP (1.8-2.0g/cm), ngoko ke, inamandla athile aphezulu.
2) Ilula kwaye iyonga amandla: Ubunzima bocango lwemoto olwenziweIzinto ze-GMTingancitshiswa ukusuka kwi-26 kg ukuya kwi-15 kg, kwaye ubukhulu bomqolo bunokuncitshiswa ukwandisa indawo yemoto. Ukusetyenziswa kwamandla yi-60%-80% kuphela yeemveliso zentsimbi kunye ne-35%-50% yeemveliso ze-aluminium.
3) Xa kuthelekiswa ne-thermosetting SMC (i-sheet molding compound), izinto ze-GMT zineengenelo zomjikelo omfutshane wokubumba, ukusebenza kakuhle kwempembelelo, ukuphindeka kwakhona, kunye nomjikelo wokugcina ixesha elide.
4) Ukusebenza kwempembelelo: Amandla e-GMT okufunxa ukutshayiswa aphindwe ka-2.5-3 kune-SMC. I-SMC, intsimbi, kunye ne-aluminium zonke zifumene ukuqhekeka okanye imifantu phantsi kokutshayiswa, kodwa i-GMT ayizange yonakale.
5) Ukuqina okuphezulu: I-GMT inelaphu le-GF, elisenokugcina imo yalo nokuba kukho impembelelo ye-10mph.
2. Ukusetyenziswa kwezixhobo ze-GMT kwicandelo leemoto
Iishiti ze-GMT zinamandla aphezulu kwaye zinokwenziwa zibe zizinto ezilula. Kwangaxeshanye, inenkululeko ephezulu yoyilo, ukufunxwa kwamandla okungqubana okunamandla, kunye nokusebenza kakuhle kokucubungula. Isetyenziswe kakhulu kwishishini leemoto ukusukela ngeminyaka yoo-1990. Njengoko iimfuno zokonga amafutha, ukuphinda kusetyenziswe, kunye nokulula kokucubungula ziqhubeka zisanda, imakethi yezixhobo ze-GMT kwishishini leemoto iya kuqhubeka ikhula ngokuthe chu.
Okwangoku, izixhobo ze-GMT zisetyenziswa kakhulu kwishishini leemoto, ikakhulu kubandakanya iifreyimu zezihlalo, iibhampa, iiphaneli zezixhobo, iihoods, iibrakethi zebhetri, iipedali zeenyawo, iziphelo zangaphambili, imigangatho, iifenda, iingcango zangasemva, uphahla, imithwalo. Izinto ezifana neebrakethi, ii-visors zelanga, iirakhi zamatayara ezingasetyenziswa, njl.
1) Isakhelo sesihlalo
Uyilo lwesihlalo olungasemva olune-compression-molded kwimoto yezemidlalo yeFord Motor Company ka-2015 iFord Mustang (eboniswe ngezantsi) luyilwe ngumthengisi/uguquleli weTier 1 Continental Structural Plastics esebenzisa iHanwha L&C's 45% unidirectional glass-reinforced fiberglass mat thermoplastic Molds for composite materials (GMT) kunye neCentury Tool & Gage, i-compression molding. Ihlangabezana ngempumelelo nemigaqo yokhuseleko yaseYurophu i-ECE yokugcina imithwalo yemithwalo.
Le nxalenye ifune ukuphinda-phinda kwe-FEA okungaphezulu kwe-100 ukuze igqitywe, isusa iindawo ezintlanu kuyilo lwesakhiwo sentsimbi sangaphambili. Kwaye igcina iikhilogram ezi-3.1 kwisithuthi ngasinye kwisakhiwo esincinci, okulula nokusifaka.
2) Umqadi wangasemva wokulwa nokungqubana
Umqadi wokulwa nokungqubana ngasemva kweTucson entsha yeHyundai (jonga umfanekiso ongezantsi) ngo-2015 wenziwe ngezinto zeGMT. Xa kuthelekiswa nezinto zentsimbi, imveliso ikhaphukhaphu kwaye ineempawu zokuthambisa ezingcono. Inciphisa ubunzima besithuthi kunye nokusetyenziswa kwepetroli ngelixa iqinisekisa ukusebenza okukhuselekileyo.
3) Imodyuli yangaphambili
IMercedes-Benz ikhethe iiQuadrant Plastic Composites GMTexTM thermoplastic composites eziqiniswe ngelaphu njengezinto zemodyuli engaphambili kwi-S-Class yayo (eboniswe ngezantsi) ye-luxury coupe.
4) Iphaneli yokukhusela umzimba esezantsi
I-Quadrant PlasticComposites isebenzisa i-GMTex TM esebenza kakuhle ukukhusela i-underbody hood kwiMercedes Off-Road Special Edition.
5) Isakhelo sesango langasemva
Ukongeza kwiingenelo eziqhelekileyo zokudibanisa ukusebenza kunye nokunciphisa ubunzima, ukwakheka kwezakhiwo ze-GMT tailgate kukwavumela iifom zemveliso ezingenakwenzeka ngentsimbi okanye i-aluminium. Isetyenziswa kwiNissan Murano, kwi-Infiniti FX45, nakwezinye iimodeli.
6) Isakhelo seDashboard
I-GMT ivelisa ingcamango entsha yeefreyimu zedeshibhodi ezenzelwe ukusetyenziswa kwiimodeli ezininzi zeFord Group: iVolvo S40 kunye neV50, iMazda, kunye neFord C-Max. Ezi zidityanisiweyo zenza uluhlu olubanzi lokudibanisa okusebenzayo. Ingakumbi ngokufaka amalungu anqamlezileyo esithuthi ngendlela yeetyhubhu zentsimbi ezibhityileyo ekubumbeni. Xa kuthelekiswa neendlela zemveli, ubunzima buncitshiswa kakhulu ngaphandle kokunyusa iindleko.
