Kutheni le nto iCarbon fiber isiya ithandwa kakhulu kwishishini leemoto?

i-carbon fiber (CF) luhlobo olutsha lwezinto zefiber ezinamandla aphezulu kunye nemodyuli ephezulu yekhabhoni engaphezulu kwe-95%. Iqulunqwe ngeflake yegraphite microcrystals kunye nezinye iifiber eziphilayo ezibekwe ecaleni kwendlela ye-axial yefiber kwaye ifunyenwe ngecarbonization kunye negraphitization ye-microcrystalline inki materials. Ifayibha yekhabhoni yinto entsha eneempawu ezigqwesileyo zoomatshini. Umlinganiselo wayo ungaphantsi kwe-1/4 yentsimbi. Amandla e-tensile ye-carbon fiber resin composite ngokuqhelekileyo ingaphezulu kwe-3500Mpa, eyi-7 ~ 9 amaxesha entsimbi. Kodwa i-carbon fiber material kuphela ecaleni kwendlela ye-fiber axis ibonisa amandla aphezulu kakhulu, ukuchasana kwempembelelo yayo imbi kwaye kulula ukuyonakalisa, ngoko ke ukuveliswa kwezixhobo zesakhiwo kuhlala kusebenzisa i-acnefit yokukhanya kwayo kwaye kunqanda ukuthwala inxalenye yecala.

Ngophando lwezifundo olusuka kwifayibha emfutshane yefayibha yekhabhoni ukuya kwifayibha ende yefayibha, itekhnoloji, kunye neemveliso ezisebenzisa ifayibha yekhabhoni ukwenza izinto zokufudumeza ziye zangena ngokuthe ngcembe kwimimandla yasemkhosini neyasekuhlaleni. Iikhompositi zekhabhoni ze-automotive zinokusetyenziswa njengeeshafti zokuqhuba iimoto, iiplate springs, iifreyimu, kunye neebrake pads. Okwangoku, izinto zensimbi zithatha malunga ne-3/4 yobunzima bomzimba wemoto. Ukuba zonke iinxalenye zentsimbi zemoto zatshintshwa yi-carbon fiber composite materials, ubunzima bomzimba wemoto buya kuncitshiswa nge-300kg, ukusebenza kakuhle kwepetroli kuya kuphuculwa ngama-36%, kwaye ukukhutshwa kwe-carbon dioxide kuya kuncitshiswa nge-17%.

1. Ukusetyenziswa komzimba wemoto kunye ne-chassis, ngenxa yokuba i-carbon fiber eyomeleziweyo ye-polymer matrix imathiriyeli ehlanganisiweyo inamandla okwaneleyo kunye nokuqina, yeyona nto ilula kakhulu yokwenza iindawo ezinkulu zesakhiwo ezifana nemizimba yemoto kunye ne-chassis. KUTHEKELELWA UKUBA UKUSETYENZISWA KWE-CARBON FIBBER COMPOSITE MATERIAL KUNOKUNCIPHA UBUNZI BOMZIMBA WE-AutoMOBILE kunye ne-chassis ngama-40% ~ 60%, elilingana ne-1/3 ~ 1/6 yobunzima besakhiwo sentsimbi. Umzimba wemoto yomdyarho oqhelekileyo kunye nomzimba wemoto oguqulwe ngokuyinxenye zonke zezonjongo, kwaye iziphumo zokubonwayo zigqwesile kwaye zipholile kakhulu.

2. Ukusetyenziswa kwe-brake pads, i-carbon fiber nayo isetyenziswe kwi-brake pads ngenxa yokukhuselwa kwayo kwendalo kunye neempawu ezixhatshazwayo, kodwa iimveliso eziqukethe i-carbon fiber composite materials ziphezulu, ngoko ke olu hlobo lwe-brake pad lusetyenziswa kakhulu. iimoto zodidi oluphezulu. Iidiski zeCarbon fiber brake zisetyenziswa kakhulu kwiimoto zomdyarho, ezinjengeemoto zeF1. Inokunciphisa isantya semoto ukusuka kwi-300 km / h ukuya kwi-50 km / h kumgama we-50 m, ngelo xesha ubushushu be-disc ye-brake buya kunyuka bube ngaphezu kwe-900 ℃, kwaye i-disc ye-brake iya kuba bomvu ngenxa yokuba. ifunxa amandla amaninzi obushushu. I-carbon fiber brake discs inokumelana namaqondo obushushu ukuya kuthi ga kwi-2 500 ° C kwaye inike uzinzo olubalaseleyo lokuqhawuka.

I-3, ukusetyenziswa kwehabhu yevili, iingcali zokwenza ivili lehabhu eJamani ziphehlelele uthotho lwamavili, zamkela uyilo lweziqwenga ezi-2, umsesane wangaphandle wenziwa ngezinto zekhabhoni fiber, kwaye ihabhu yangaphakathi yialloy ekhaphukhaphu, enezikrufu zentsimbi, xa kuthelekiswa ne ubukhulu bevili bumalunga nama-40% ngaphantsi. I-hub ye-intshi engama-20, umzekelo, inobunzima be-6 kg, ngelixa i-hub eqhelekileyo inobunzima be-18 kg. Uhlobo lwe-RX-X ivili elikhethekileyo lemoto elenziwe nguKahm waseBritani esebenzisa iCFRP inobunzima obuyi-6 kg kuphela, enokuthi ibaleke ngesantya esiphezulu kwaye icuthe amandla e-radial inertia yevili. Iphuhliswe yi-DYMAG e-UK, ivili lekhabhoni elikhaphukhaphu kakhulu/ivili le-magnesium linamacandelo amabini, i-carbon fiber wheel mesh, kunye ne-magnesium brake disc, edityaniswe yi-hardware ekhethekileyo ye-titanium-plated.

I-4, ukusetyenziswa kwe-shaft ye-shaft yamandla e-automobile drive shaft inzima ngakumbi, ngakumbi kufuneka ithwale i-torque enkulu, inike ingqwalasela epheleleyo kwi-carbon fiber eyomeleziweyo yezinto ezidibeneyo i-anisotropy, amandla aphezulu, kunye nemodyuli yeempawu ezisezantsi, ngoko kusetyenziswa i-carbon fiber. ishafti eyomeleziweyo yothumelo lwecomposite ukuze ithathe indawo yeemveliso zetsimbi, ukuhlangabezana neemfuno zokusetyenziswa. I-Carbon fiber driveshaft ayinciphisi nje ubunzima ngama-60% kodwa ikwanokumelana nokudinwa okungcono kunye nokuqina.

Okoko nje ukusetyenziswa kwefayibha yekhabhoni kwimoto kukufezekisa ubunzima bemoto kunye nokuhlangabezana nemfuno engqongqo yemoto, ayinakuhlangabezana nemfuno yelizwe jikelele yokonga amandla kunye nokunciphisa ukukhutshwa kombane, kodwa ikwakhawulelana nengxaki yokonga amafutha. ezinxulumene neVolkswagen.
