Carbon fiber inozivikanwa se "goridhe dema" mune yakakwirira-inoshanda zvinhu.Kubatsira kwekuita kwese kwakakwira zvakanyanya.Iyo intuitive data inosanganisira kusimba kwayo, simba rekukotama, nezvimwewo, nekuti density yaro zvakare yakadzikira zvakanyanya, saka zvichienzaniswa nezvimwe zvinhu Huyero hwese hwesimba uye hutete uye reshiyo yemhando nyeredzi zvakare yakanyanya kukwirira.Vanhu vazhinji havazive zvazvinoreva kana vakanzwa chaiyo simba uye chaiyo modulus.Ini ndichakuudza nezve ruzivo rwekabhoni fiber mune ino chinyorwa.
Simba chairo
Kududzirwa kwehunyanzvi kwesimba rakananga ndiko kuenzanisa pakati pekuenderana kwezvinhu uye kuwanda kwezvinhu.Kana iyo chaiyo kusimba kwechinhu chakanyanya kukwirisa, zvinoreva kuti zvinhu zvacho zvine huremu hwakanaka kwazvo, kunyanya kune zvigadzirwa zvinoda simba.Ipapo inogona kushandiswa kuminda yakadai semotokari, ndege, maroketi, uye ngarava.
Nei kune shoko rakadaro sesimba chairo?Nekuti kana tikatarisa chinhu, hatigone kungotarisa kushanda kwayo kwesimba.Semuenzaniso, kusimba kwese kwesimbi yako yezvinhu kunofanirwa kunge kwakakwira kupfuura iyo yezvigadzirwa zvepurasitiki, asi inoshandiswa kune zvakawanda zvigadzirwa.Iyo haigone kugutsikana, sezvakangoita indasitiri yemotokari, kana mota ichimhanya, kuchengetedzeka kwesimbi kwakakwira zvakanyanya, uye hazvisi nyore kukuvara nekudhumhana, asi kana mota yese yakagadzirwa nesimbi, ichaita. kutyaira kwemotokari kuita kwakanaka kwazvo.Kuderera kwesimba rekushandisa kuchave kwakakwira, ndosaka zvikamu zvakawanda pamotokari zvichisarudza zvinhu zvepurasitiki.Kunyangwe kusimba kwezvigadzirwa zvepurasitiki zvisina kunaka senge yemidziyo yesimbi, iyo nyeredzi yemhando yakareruka.Iyo chaiyo kusimba kwe fiber zvinhu yakakwira zvakanyanya, uye zvinhu zvepurasitiki zvinogona kubviswa muchiedza chinongedzo, uye yakakwirira kupfuura simbi zvinhu musimba rekubatanidza.Iyo kabhoni fiber zvinhu ine yakanyanya kusimba yakananga kuita.
Iyo unit yesimba chairo iMPa (g.cm3, zvinoreva kuti iyi ndiyo simba rezvinhu / density yezvinhu, uye iyo chaiyo simba rekabhoni fiber rakakwirira kwazvo, uye simba rekabhoni fiber rinogona kuderedzwa kusvika 350OMP?a. Density ingori 1.6gycm uye yakaverengerwa nenzira iyi, iyo yakazara chaiyo simba inogona kusvika 2200MPa/g.cm3, iyo inokwira zvakapetwa kazana kupfuura iyo aruminiyamu alloy mumidziyo yedu yesimbi. Naizvozvo, inogona kushandiswa muminda inoda zvose simba uye kuderedza uremu, ndicho chikonzero zvinonzi motokari, ndege, uye maroketi Kune nhamba dzakawanda dzinosarudza carbon fiber material samples kune zvigadzirwa zvakadai sezvikepe uye ngarava.
Specific modulus
Iyo pfungwa yeiyo chaiyo modulus ingori kuenzanisa pakati pesimba rekusimba rezvinhu uye density yezvinhu.Zvichitaurwa zviri nyore, iko kugona kukotama kwezvinhu zvatataura.Kune rumwe rutivi, zvinhu zvakajairika mukati mayo chiyero chezvigadzirwa zvepurasitiki kune simbi.Nyaya yacho yakakwirira kudarika yesimbi kupfuura iyo nyeredzi yemuenzaniso.Iyo chaiyo modulus yekabhoni fiber zvinhu zvakare yakanaka kwazvo.
Ipapo tinowanzo taura kuti kuomarara chaiko kwekabhoni faibha T30 kunogona kusvika 140GPa/g.cm3, izvo zvinoita kuti iyo chaiyo modulus yekabhoni faibha zvinhu zvigadzirwa zvive zvakanaka, izvo zvinoitawo kuti kabhoni yakaputsika faibha zvinhu zvine zvakanakira kuiswa kune zvakawanda zvigadzirwa, senge yakatyoka fiber Kushandiswa kweiyo yakatevedzana uye kabhoni fiber ganda kunogona kuita kuti simba rose rinoshandiswa ridzike, uye kana rakanganiswa, rinogona kuve nekugadzikana kwakanaka kwechigadzirwa uye haisi nyore kukuvadza nekukanganisa.
Izvo zviri pamusoro apa kududzirwa kwezviri mukati meiyo chaiyo simba reshiyo yekabhoni fiber zvinhu, chiri zvakare chikonzero chakakosha neicarbon fiber zvinhuinogona kushandiswa munzvimbo dzakawanda.Panguva ino, nekuenderera mberi nekuvandudzika kwekabhoni fiber tekinoroji, ndinotenda akawanda uye akawanda maindasitiri.Panguva ino, vagadziri vazhinji vachada kutsiva zvigadzirwa zvavo nebhora fiber zvinhu, saka vanofanirwa kuwana vagadziri vezvigadzirwa zvekabhoni vakakodzera kuti vashande navo.
Isu tiri mugadziri akabatanidzwacarbon fiber zvigadzirwakwemakumi emakore.Tine ruzivo rwakapfuma rwekugadzira.Isu tiri kuita mukugadzira uye kugadzirisa kabhoni fiber zvigadzirwa.Tine midziyo yekuumba yakakwana uye yakakwana yekugadzirisa michina.Tinogona kupedzisa kugadzirwa kwemhando dzakasiyana dzecarbon fiber zvigadzirwauye gadzirisa kugadzirwa zvinoenderana nemifananidzo.Iyo kabhoni fiber board zvigadzirwa zvinogadzirwa zvakare kure kure nemaindasitiri mazhinji, uye zvave zvichizivikanwa nekurumbidzwa.
