Pakati pezvinhu zvakawanda, kabhoni fiber composites (CFRP) yakabhadharwa zvakanyanya uye yakawedzera kutariswa kune yavo yakanakisa simba rayo, kuomarara kwakananga, corrosion resistance, uye kuneta kuramba.
Iwo akasiyana hunhu pakati pekabhoni fiber kompositi uye simbi zvinhu zvinopawo mainjiniya neakasiyana dhizaini mazano.
Inotevera ichave iri nyore kuenzanisa pakati pekabhoni fiber composites uye yechinyakare simbi maitiro uye mutsauko.
1. Kuomarara kwakananga uye kusimba chaiko
Zvichienzaniswa nezvinhu zvesimbi, kabhoni fiber zvinhu zvine huremu, simba rakananga, uye kuomarara chaiko.Iyo modulus yeresin-yakavakirwa kabhoni fiber yakakwira kupfuura iyo yealuminium alloy, uye kusimba kweresin-based kabhoni fiber yakakwira zvakanyanya kupfuura iyo yealuminium alloy.
2. Designability
Metal zvinhu zvinowanzova zvakafanana zvepabonde, pane goho kana mamiriro egoho chiitiko.Uye iyo single-layer kabhoni fiber ine pachena inotungamira.
Iwo ma mechanika ezvivakwa pamwe nefiber direction ndeye 1 ~ 2 maodha ehukuru akakwira kupfuura ayo ari padhuze nefiber direction uye longitudinal uye transverse shear zvivakwa, uye kushushikana-kurovera macurves ane mutsara elastic isati yatyoka.
Naizvozvo, iyo kabhoni fiber zvinhu inogona kusarudza yekuisa kona, iyo yekuisa reshiyo, uye yekumisikidza kutevedzana kweimwe-layer kuburikidza nelamination plate theory.Zvinoenderana nehunhu hwekugovewa kwemutoro, kuomarara uye kuita kwesimba kunogona kuwanikwa nekugadzira, nepo zvechinyakare simbi midziyo inogona chete kukora.
Panguva imwecheteyo, iyo inodiwa mu-ndege kuoma uye simba pamwe chete nekusiyana-siyana mu-ndege uye kunze-kwe-ndege kubatanidza kuoma kunogona kuwanikwa.
3. Corrosion resistance
Zvichienzaniswa nezvinhu zvesimbi, kabhoni fiber zvinhu zvine asidhi yakasimba uye alkali kuramba.Carbon fiber is a microcrystalline chimiro chakafanana ne graphite crystal inoumbwa ne graphitization pane yakakwirira tembiricha ye 2000-3000 ° C, ine yakanyanya kupikisa kune yepakati corrosion, inosvika 50% hydrochloric acid, sulfuric acid kana phosphoric acid, iyo elastic modulus, simba, uye dhayamita zvinoramba zvisingachinjiki.
Naizvozvo, sechinhu chinosimbisa, kabhoni faibha ine garandi yakakwana mukupokana necorrosion, akasiyana matrix resin mukupokana kwekupokana kwakasiyana.
Kufanana neyakajairwa kabhoni fiber-reinforced epoxy, iyo epoxy ine nani mamiriro ekunze uye ichiri kuchengetedza simba rayo zvakanaka.
4. Anti Fatigue
The compression strain uye yakakwirira strain level ndizvo zvinhu zvikuru zvinopesvedzera kuneta zvimiro zvekabhoni fiber composites.Izvo zvekuneta zvimiro zvinowanzoiswa pasi pekuyedzwa kwekuneta pasi pekumanikidzwa (R = 10) uye tensile kudzvanywa (r = -1), nepo zvigadzirwa zvesimbi zvinoiswa pasi pekunetseka kuneta kuyedzwa pasi pekumanikidzwa (R = 0.1).Zvichienzaniswa nesimbi zvikamu, kunyanya aruminiyamu alloy zvikamu, kabhoni fiber zvikamu zvine zvakanakisa kuneta zvimiro.Mumunda wemotokari chassis uye zvichingodaro, kabhoni fiber composites ine zvirinani mabhenefiti ekushandisa.Panguva imwecheteyo, pane inenge isina notch effect mu carbon fiber.Iyo SN curve yemuyedzo wenotched wakafanana neiyo yebvunzo isina kunyorwa muhupenyu hwese hweakawanda kabhoni fiber laminates.
5. Recoverability
Parizvino, iyo yakakura kabhoni fiber matrix inogadzirwa ne thermosetting resin, iyo yakaoma kubviswa uye kushandiswa zvakare mushure mekurapa uye kuyambuka-kubatanidza.Naizvozvo, kuomerwa kwekabhoni fiber kudzoreredza nderimwe remabhodhoro ekusimudzira maindasitiri, uye zvakare idambudziko rehunyanzvi rinoda kugadziriswa nekuchimbidza kune yakakura-scale application.Parizvino, nzira zhinji dzekudzokorodza zvakare kumba nekune dzimwe nyika dzine mutengo wakakwira uye dzakaoma kugadzirwa.Walter kabhoni faibha ari kushingaira kuongorora zvigadziriswe zvigadziriswe, apedza akati wandei masampuli eyedzo kugadzirwa, kudzoreredza mhedzisiro yakanaka, ine misa yekugadzira mamiriro.
Mhedziso
Zvichienzaniswa nemidziyo yechinyakare yesimbi, kabhoni fiber zvinhu zvine zvakasarudzika mumakanika zvivakwa, huremu, dhizaini, uye kuramba kuneta.Nekudaro, kugona kwayo kugadzira uye kudzoreredza kwakaoma zvichiri mabhodhoro ekuwedzera kwayo kushandiswa.Zvinotendwa kuti kabhoni fiber ichashandiswa zvakanyanya uye zvakanyanya pamwe nekuvandudza tekinoroji uye maitiro.
