Kuita kwepamusoro kwekabhoni fiber zvinhu kunoita kuti ive nekuita kwakanyanya kwekushandisa mumaindasitiri mazhinji.Apo iyocarbon fiberchigadzirwa chinoshandiswa, chinowanikwa kuti mutengo wose wakakwirira.Nzvimbo iyo mutengo weyakaputsika fiber chigadzirwa chakakwira ine chekuita nenzvimbo dzakawanda.Chikwata chedu chinokuudza iwe kubva pakuona kwekabhoni fiber.
Iyo kabhoni fiber zvigadzirwa zvatinoona zvakasiyana zvakanyanya kubva kune yedu kabhoni fiber zvinhu, nekuti mafiber haagone kugadzirwa ega, uye anofanirwa kusanganiswa neresin matrix kupedzisa kugadzirwa kwezvigadzirwa.Chimwe chezvikonzero nei mutengo wezvigadzirwa zvefiber uchidhura ndechekuti mutengo wekabhoni filaments wakakwira, saka tinofanira kutanga tanzwisisa kabhoni fiber tow material.
Kune marudzi matatu eakatyoka fiber tow, anosanganisira polyacrylonitrile (PAN)-based carbon fiber, pitch-based carbon fiber uye gum-based carbon fiber.Iyo inonyanya kuzivikanwa PAN-based carbon fiber ndiyo inonyanya kuzivikanwa, uye chikamu chemusika chese chiri pamusoro pe90%, saka ikozvino thermoplastic carbon fiber inonyanya kureva PAN-based carbon fiber.
Polyacrylonitrile yakagadzirwawo pakutanga.Yakagadzirwa naAkio Kondo muJapan muna 1959, uye ipapo yakawanda-yakagadzirwa muToray muna 1970. Iyo yose polyacrylonitrile carbon filament ine simba guru kwazvo uye maitiro emuenzaniso nyeredzi.Iyo asphalt-based fiber yakagadzirwa neGunma University kuJapan muna 1965. Iyi carbon fiber tow ine yakanyanya kupisa conductivity yakakwira se90OGPa, saka inonyanya kushandiswa kune zvakakosha zvinoshanda.Viscose-yakavakirwa kabhoni faibha yainyanya kushandiswa seyakaumbwa zvinhu zvemuchadenga zvivharo zvekupisa muma1950s, uye ndizvo zvakare zvinhu zvichashandiswa izvozvi.Saka takaona kuti maviri ekutanga akagadzirwa nemaJapan, ndosaka mwero wekuyerwa kwekabhoni fiber tow wakavakirwa paToray kabhoni fiber zvinhu.
Ehe, kutsvagisa uye kusimudzira kabhoni fiber tow precursors yakaramba ichifambira mberi mumakore achangopfuura, asi mhedzisiro yacho haisati yaita.Mazuva ano, PAN-yakavakirwa ndiyo ichiri yakakosha.Mukugadzirwa kwekabhoni filaments, iyo kabhoni goho rematatu ekutanga anogona kusvika kupfuura B80%.Tichifunga, mutengo weiyo carbon fiber filaments ichave yakaderera, asi kugadzirwa kwepitch-based kunoda kunatswa uye kugadziridzwa.Iyi nzira ichawedzera zvakanyanya mari yekugadzira uye kuderedza goho kusvika ku30%.Saka iyo PAN-yakavakirwa ichiri kufarirwa.
Saka ngatitarisei iyo inoshandiswa zvakanyanya PAN carbon fiber.Mutengo wePAN-based carbon fiber wakaderera zvakanyanya pane weasphalt-based carbon fiber, uye inogona kuiswa muminda yakawanda.Mutengo wePAN-based fiber yemasatelliti wakakwira kusvika pa200 yen/kg, ukuwo mutengo wecarbon fiber wemota wakadzikira se2,000 yen/kg.
Ipapo isu tichiri kushandisa Toray's kabhoni fiber zvinhu sehwaro.Pano, iyo PAN-yakavakirwa yakatyoka fiber yakakamurwa kuita mahombe uye madiki madhiri.Semuenzaniso, mutengo weyakajairika 3K i50-70 US madhora / kg, uye mutengo we6K i4-50 US madhora / kg.Naizvozvo, isu tinogona zvakare kunzwisisa kuti sei madiki madiki achinyanya kushandiswa muminda yepamusoro-inoshanda.
Nokudaro, tinoti mutengo we carbon fiber uchave wakadhura.Hazvisi pasina chikonzero kuti ine zvakawanda zvekuita nezvinhu zvakasvibirira.Pamusoro pezvo, mutengo wezvigadzirwa zvekabhoni fiber wakanyanya kukwira, uye une zvakawanda zvekuita nenyaya yekuti zvigadzirwa zvedu zvekabhoni fiber zvinoda basa rakawanda nemidziyo.
