Phakathi kwezixhobo ezininzi, i-carbon fiber composites (CFRP) ihlawulwe ngakumbi nangakumbi kumandla abo abalaseleyo, ukuqina okuthe ngqo, ukuxhathisa umhlwa, kunye nokumelana nokudinwa.
Iimpawu ezahlukeneyo phakathi kwee-carbon fiber composites kunye nezixhobo zetsimbi nazo zibonelela ngeenjineli ngeengcamango ezahlukeneyo zokuyila.
Oku kulandelayo kuya kuba luthelekiso olulula phakathi kwee-carbon fiber composites kunye neempawu zetsimbi zendabuko kunye nokungafani.
1. Ukuqina okuthe ngqo kunye namandla athile
Xa kuthelekiswa nezinto zetsimbi, izinto zekhabhoni zefiber zikhaphukhaphu, amandla athile aphezulu, kunye nokuqina okuthile.Imodyuli ye-resin-based carbon fiber iphezulu kune-aluminium alloy, kwaye amandla e-resin-based carbon fiber aphezulu kakhulu kune-aluminium alloy.
2. Ukuyilwa
Izinto zetsimbi zihlala zifana nesini esifanayo, kukho isivuno okanye isivuno esinemiqathango.Kwaye ifayibha yekhabhoni yomgangatho omnye inolwalathiso olucacileyo.
Iipropathi zoomatshini ecaleni komkhombandlela wefayibha zi-1 ~ 2 ii-odolo zobukhulu eziphezulu kunezo zisecaleni kwendlela yefayibha ethe nkqo kunye neempawu zokucheba ezinde kunye nezinqamlezayo, kwaye ijika loxinzelelo loxinzelelo lilastiki yomda phambi kokwaphuka.
Ke ngoko, i-carbon fiber material inokukhetha i-angle yokubeka, umlinganiselo wokubeka, kunye nokulandelelana kokubeka kwe-single-layer ngokusebenzisa ithiyori ye-lamination plate.Ngokweempawu zokusabalalisa umthwalo, ukuqina kunye nokusebenza kwamandla kunokufumaneka ngokuyila, ngelixa izinto zetsimbi zendabuko zinokuqiniswa kuphela.
Ngexesha elifanayo, ukuqina okufunekayo kwinqwelomoya kunye namandla kunye nokungaqhelekanga kwinqwelomoya kunye nokuqina kokudibanisa ngaphandle kwendiza kunokufumaneka.
3. Ukumelana nokubola
Xa kuthelekiswa nezinto zetsimbi, izinto zekhabhoni zefiber zineasidi eyomeleleyo kunye nokumelana nealkali.Ifayibha yeCarbon sisakhiwo se-microcrystalline esifana nekristale yegraphite eyenziwe yigraphitization kubushushu obuphezulu be-2000-3000 °C, enokumelana okuphezulu nokugqwala okuphakathi, ukuya kuthi ga kwi-50% ye-hydrochloric acid, i-sulfuric acid okanye i-phosphoric acid, imodyuli elastiki, amandla, kunye nedayamitha zihlala zingatshintshanga.
Ngoko ke, njengento yokomeleza, i-carbon fiber inesiqinisekiso esaneleyo kwi-corrosion resistance, i-resin ye-matrix eyahlukileyo ekuxhathiseni ukubola iyahluka.
Njenge-carbon fiber-reinforced epoxy eqhelekileyo, i-epoxy inokumelana nemozulu engcono kwaye igcina amandla ayo kakuhle.
4. Anti Fatigue
Ukunyanzeliswa koxinzelelo kunye nenqanaba eliphezulu loxinzelelo zizinto eziphambili ezichaphazela iimpawu zokudinwa kwee-carbon fiber composite.Iimpawu zokukhathala ngokuqhelekileyo zixhomekeke kwiimvavanyo zokukhathala phantsi koxinzelelo (R = 10) kunye noxinzelelo lwe-tensile (r = -1), ngelixa izinto zetsimbi zixhomekeke kwiimvavanyo zokukhathala phantsi koxinzelelo (R = 0.1).Xa kuthelekiswa neengxenye zetsimbi, ngakumbi iinxalenye ze-aluminium alloy, iindawo ze-carbon fiber zineempawu ezintle zokudinwa.Kwintsimi ye-chassis yemoto njalo njalo, i-carbon fiber composites ineenzuzo ezingcono zokusetyenziswa.Ngexesha elifanayo, akukho phantse isiphumo se-notch kwi-carbon fiber.Ijika le-SN lovavanyo lwe-notched lifana nelo lovavanyo olungabonakaliyo kubomi bonke be-carbon fiber laminates.
5. Ukubuyiswa kwakhona
Okwangoku, i-carbon fiber matrix evuthiweyo yenziwe nge-resin thermosetting, ekunzima ukuyikhupha kwaye isetyenziswe kwakhona emva kokunyanga kunye nokudibanisa.Ngoko ke, ubunzima bokubuyiswa kwe-carbon fiber ngenye yeebhotile zophuhliso lwamashishini, kunye nengxaki yezobuchwepheshe ekufuneka isonjululwe ngokukhawuleza kwisicelo esikhulu.Okwangoku, uninzi lweendlela zokurisayikilisha ekhaya naphesheya zineendleko eziphezulu kwaye kunzima ukwenziwa kwezoshishino.I-Walter carbon fiber ihlolisisa izisombululo ezinokuphinda zisetyenziswe, igqibe inani leesampuli zemveliso yovavanyo, umphumo wokubuyisela ulungile, kunye neemeko zemveliso yobuninzi.
Ukuqukumbela
Xa kuthelekiswa nezinto zentsimbi zemveli, izinto zekhabhoni zefiber zineengenelo ezizodwa kwiipropathi zoomatshini, zikhaphukhaphu, zinokwakheka, kunye nokumelana nokudinwa.Nangona kunjalo, ukusebenza kwayo kakuhle kwemveliso kunye nokubuyiselwa okunzima kuseyimiqobo yesicelo sayo esongezelelweyo.Kukholelwa ukuba i-carbon fiber iya kusetyenziswa ngakumbi nangakumbi kunye nokuveliswa kweteknoloji kunye nenkqubo.
