Musanganiswa (composite material) zvinoreva rudzi rutsva rwezvinhu zvakasanganiswa kubva mumhando dzakasiyana-siyana.Iyo kabhoni fiber zvinhu yatinowanzo taura ichinhu chakaumbwa uye inonzi "goridhe dema" mune zvakaumbwa zvinhu.Carbon fiber composite zvinhu zvinoumbwa nekabhoni fiber tow uye matrix zvinhu.(Matrix zvinhu zvakaita seresin, ceramics, simbi, nezvimwewo) zvakasanganiswa zvinhu, zvakanyanyisa kunaka kwekuita kunoita kuti ive kurambidzwa kwakanaka kwezvinhu zvechinyakare.Ichi chinyorwa chichataura pamusoro pepamusoro-kuita zvakanaka zvekabhoni fiber composite zvinhu.
1. Kunyanya kuderera
Kuwanda kwekabhoni E-dimensional composite material yakaderera zvikuru, density inongova 1.5gcm3.Zvichienzaniswa nezvinhu zvesimbi, zvakaita sesimbi ine density ye7.8gycm3 uye aruminiyamu alloy ine density ye2.8glcm3, vaviri ava vanogona kuona kuti carbon fiber composite zvinhu zvine density yakaderera, huremu hwese hwechigadzirwa chakaitwa nechinhu ichi. zvakare yakareruka, uye ine yakanaka kwazvo lightweight mhedzisiro muminda yakawanda, inova mashandiro ayo echinyakare simbi zvinhu haana.
⒉ kusimba kwakanyanya
Iyo yakatyoka fiber material ine yakanyanya simba kuita, iyo inogona kusvika pakusimba kwe350OMPa.Kuenzaniswa nesimbi, kusimba kwesimbi i65OMPa, uye kusimba kwealuminum alloy ndeye 42OMPa.Nenzira iyi, zvinogona kuwanikwa kuti iyo yakakwira simba kuita kwekabhoni fiber yakanaka kwazvo.Yakakwirira, inogona kuita kuti kushanda kwesimba kwechigadzirwa kukwane zvakakwana zvinodiwa zvekare zvechigadzirwa, kunyange kana carbon fiber iri anisotropic, ichange ichiri yakakwirira kudarika kusimba kwechigadzirwa chesimbi.
3. Good corrosion resistance
Carbon faibha zvinhu zvine mabhenefiti akanaka ekuita acid, kuramba alkali uye oxidation kuramba, izvo zvinoita kuti kabhoni faibha zvinhu zvive nemabhenefiti ekushandisa kwakawanda kwezvakatipoteredza, senge nharaunda yakanyorova kana kabhoni fiber zvigadzirwa zvinogara zviri pachena kunze, zvisiri nyore kuita ngura. kana kupera kwehwindo, ine yakakwira kwazvo application performance.
4. Good impact resistance
Carbon fiber zvinhu zvine yakanakira kukanganisa kuramba.Mushure mekugadzirwa kuita kabhoni fiber zvigadzirwa, ine yakanaka kwazvo yekukanganisa kupikisa muchiitiko chekudhumhana kukuru.Kuchengetedza kuchengetedzwa kwemotokari, nokuti mukati meiyo carbon fiber chigadzirwa i carbon filament, iyo yakanyatsobatanidzwa kuburikidza nematrix zvinhu, kuitira kuti simba rigone kupararira zvakanaka kana simba rinoshandiswa.
5. Good machinability
Carbon fiber zvinhu zvakagara nhaka kuchinjika kwefibers zvakanaka kwazvo, izvo zvinoita kuti kabhoni fiber zvigadzirwa zvakagadzirwa nekabhoni fiber zvinhu zvive nedhizaini yakanaka, uye inogona kugadzirwa inochinjika zvichienderana nezvinodiwa nevatengi chigadzirwa, zvichiita kuti kuita kwese kwechigadzirwa kuve nani.Inogona kusangana nezvinodiwa, uye inogona zvakare kuita interlayer dhizaini pakati pechigadzirwa.Semuenzaniso, kune madhizaini akadaro ekushandisa pamidziyo yekurapa uye zvitima zvinomhanya.Iyo chiedza nyeredzi kuratidza kuita kuri nani, uye zvakare ine yakanaka simba rekutungamira dhizaini., saka zviri nyore kune chaiyo kushandiswa kwechigadzirwa.
6. Low coefficient of thermal kuwedzera
Carbon fiber zvinhu zvine yakaderera coefficient yekuwedzera kwekupisa, iyo zvakare ine yakanaka kwazvo performance application mukana mune zvimwe kabhoni fiber zvigadzirwa zvinoda kunyatsoita, semateresikopu, chaiwo vatongi, kusanganisira Xuan Renwei mune aerospace uye mamwe minda.Zvigadzirwa zvinogona kuita kuti huwandu hwekuita basa huve nani.
