Kungani i-Carbon fiber iya ithandwa kakhulu embonini yezimoto?

i-carbon fibre (CF) iwuhlobo olusha lwe-fiber material enamandla amakhulu kanye ne-modulus ephezulu ye-carbon content engaphezu kwama-95%. Yakhiwe nge-flake graphite microcrystals kanye neminye imicu ye-organic enqwabelene eduze kwesiqondiso se-axial se-fiber futhi itholwe nge-carbonization kanye ne-graphitization yezinto ze-inki ze-microcrystalline. I-Carbon fiber iyimpahla entsha enezici ezinhle kakhulu zokusebenza. Ingxenye yayo ingaphansi kwe-1/4 yensimbi. Amandla aqinile we-carbon fibre resin composite ngokuvamile angaphezulu kuka-3500Mpa, okuyizikhathi ezingu-7~9 kunensimbi. Kodwa impahla ye-carbon fibre ehambisana ne-fiber axis direction ibonisa amandla aphezulu kakhulu, ukumelana kwayo komthelela kumpofu futhi kulula ukulimaza, ngakho-ke ukukhiqizwa kwezingxenye zesakhiwo kuvame ukusebenzisa inzuzo yakho yokukhanya okuqinile futhi kugweme ukuthwala ingxenye yomthelela oseceleni.

Ngocwaningo lwezemfundo olusuka kwi-short-fiber carbon fiber kuya ku-long-fiber carbon fiber, ubuchwepheshe, kanye nemikhiqizo esebenzisa i-carbon fibre ukwenza izinto zokufudumeza ingene kancane kancane emkhakheni wezempi kanye nowomphakathi. Izinhlanganisela ze-carbon fibre yezimoto zingasetshenziswa njengamashafu e-automotive drive, ama-plate springs, amafreyimu, nama-brake pads. Njengamanje, izinto zensimbi zibalelwa ku-3/4 wesisindo somzimba wemoto. Ukube zonke izingxenye zensimbi zemoto bezithathelwa indawo yi-carbon fibre composite materials, isisindo somzimba wemoto besingehliswa ngo-300kg, ukusebenza kahle kukaphethiloli bekuzothuthukiswa ngo-36%, futhi ukukhishwa kwe-carbon dioxide kuzokwehliswa ngo-17%.

1. Ukusetshenziswa komzimba wemoto kanye ne-chassis, ngenxa yokuthi i-carbon fibre eqiniswe i-polymer matrix eyinhlanganisela inamandla anele nokuqina, iyinto elula kakhulu yokukhiqiza izingxenye ezinkulu zesakhiwo njengemizimba yemoto kanye ne-chassis. KULINGANISELWA UKUTHI UKUSETSHENZISWA KOKUSEBENZA KWE-CARBON FIBBER COMPOSITE MATERIAL KUNGEHLISA UBUNINGI BOMZIMBA WE-Automobile kanye ne-chassis ngo-40% ~ 60%, okulingana no-1/3 ~ 1/6 wesisindo sesakhiwo sensimbi. Umzimba wemoto yomjaho ojwayelekile kanye nomzimba wemoto oshintshwe ingxenye konke kungokwale njongo, kanye nemiphumela yokubuka mihle kakhulu futhi ipholile kakhulu.

2. Ukusetshenziswa kwama-brake pads, i-carbon fiber iphinde isetshenziswe kuma-brake pads ngenxa yokuvikelwa kwemvelo kanye nezici ezingagugi, kodwa imikhiqizo equkethe izinto ze-carbon fibre composite iphezulu, ngakho lolu hlobo lwe-brake pad lusetshenziswa kakhulu izimoto ezisezingeni eliphezulu. Ama-Carbon fiber brake discs asetshenziswa kakhulu ezimotweni zomjaho, njengezimoto ze-F1. Iyakwazi ukwehlisa ijubane lemoto isuke ku-300 km/h iye ku-50 km/h ebangeni elingu-50 m, ngaleso sikhathi izinga lokushisa le-brake disc lizokhuphuka lifinyelele ngaphezu kuka-900 ℃, bese kuthi i-brake disc ibebomvu ngoba imunca amandla amaningi okushisa. Amadiski e-carbon fiber brake akwazi ukumelana namazinga okushisa afika ku-2 500 ° C futhi anikeze ukusimama okuhle kakhulu kwamabhuleki.

3, ukusetshenziswa kwehabhu lamasondo, ochwepheshe bokukhiqiza ihabhu lamasondo eJalimane bethule uchungechunge lwamasondo, bamukela umklamo wezingcezu ezi-2, indandatho yangaphandle yenziwe nge-carbon fiber material, kanti ihabhu elingaphakathi liyingxubevange engasindi, enezikulufu zensimbi engagqwali, uma kuqhathaniswa ne ubukhulu obujwayelekile besisindo sesondo cishe bungaphansi kwama-40%. Ihabhu elingama-intshi angu-20, isibonelo, linesisindo esingu-6 kg, kuyilapho ihabhu evamile inesisindo esingaba ngu-18 kg. Isondo elikhethekile lohlobo lwe-RX-X elenziwe uKahm waseBrithani esebenzisa i-CFRP linesisindo esingu-6 kg kuphela, elingagijima ngesivinini esiphezulu futhi linciphise amandla e-radial inertia esondo. Ithuthukiswe yi-DYMAG e-UK, isondo le-carbon fibre/magnesium elilula kunawo wonke emhlabeni linezingxenye ezimbili, i-carbon fibre wheel mesh, kanye ne-magnesium brake disc, exhunywe nge-hardware ekhethekile ye-titanium.

4, ukusetshenziswa kwe-shaft ye-drive shaft ye-automobile drive shaft kuyinkimbinkimbi kakhulu, ikakhulukazi kufanele kube ne-torque enkulu, kucatshangelwa ngokugcwele i-anisotropy ye-carbon fibre eqinisiwe, amandla aphezulu, kanye ne-modulus yezici eziphansi kakhulu, ngaleyo ndlela zisebenzisa i-carbon fiber. umshini wokudlulisela oyinhlanganisela oqinisiwe wokubuyisela imikhiqizo yensimbi, uhlangabezane nemfuneko yokusebenzisa. I-Carbon fiber driveshaft ayigcini nje ngokunciphisa isisindo ngo-60% kodwa futhi inokumelana nokukhathala okungcono nokuqina.

Inqobo nje uma ukusetshenziswa kwe-carbon fiber emotweni kuwukufeza isisindo esincane semoto futhi ihlangabezane nesidingo esiqinile semoto, ayikwazi ukuhlangabezana nesidingo somhlaba wonke sokonga nokunciphisa ukukhishwa kwamandla kodwa futhi ihlangabezane nenkinga yokonga uphethiloli. ihlobene neVolkswagen.
