Yakawanda sei tembiricha yakakwira inogona kumira kabhoni fiber, nei akawanda kabhoni fiber zvigadzirwa zvisingagone kutonhora kwakanyanya

Kupisa kwakakura sei kunogona kumira kabhoni fiber
Carbon fiber pachayo ine yakanyanya kupisa tembiricha kuramba, uye inogona kunzi yakanyanya kupisa tembiricha inodzivirira zvinhu, asi kabhoni fiber composite zvinhu zvinoenderana nematrix zvinhu.
Yan F cone inobvisa zvinhu kubva mupetroleum nemarasha.Kutanga, polyacrylonitrile inotorwa, uye ipapo kabhoni fiber inotorwa kuburikidza ne polyacrylonitrile.Izvo zvinodiwa zvehunyanzvi pano zvakakwirira kwazvo, uye oxidation, carbonization uye graphitization mukuita kwese zvese Inoda tembiricha yakakwira kuti ipedze, kunyanya pasi pekushisa kwakanyanya kwezviuru zvemadhigirii ekucherwa kwematombo, mushure mekubvisa magazini, iyo kabhoni fiber tow. inowanikwa, saka iyo kabhoni fiber pachayo ine yakanyanya kupisa tembiricha kuramba, inogona kutsungirira tembiricha yakakwira ye3000 ℃, uye inogona kuchengetedza yakanaka kuita mukana.
Sei akawanda kabhoni fiber zvigadzirwa zvisingamiri kune yakanyanya kupisa?
Sezvambotaurwa pamusoro, kabhoni fiber ine yakanaka uye yakakwirira tembiricha kuramba.Mukugadzirwa kwekabhoni fiber zvigadzirwa, haisi kungoita zvinhu zvekabhoni fiber.Chinhu che matrix chinodiwa zvakare kupedzisa kugadzirwa kweanonoka fiber zvigadzirwa.Carbon fiber zvigadzirwa zvinopokana nekupisa kwakanyanya.Funga nezvekupisa kwekushisa kwepamusoro pezvinhu zvepasi.
Icho chokwadi chekuti zvigadzirwa zvakawanda zvekabhoni fiber hazviunyana uye zvinopisa imhaka yekuti kabhoni faibha inoumbwa zvinhu zvinonyanya kabhoni fiber + resin-based composite zvinhu, uye zvirimo zvekunonoka fiber tow mune inoumbwa zvinhu zvinenge 40% -45%, saka. kugadzirwa Kunyanya kupisa kwekushisa kweyakapedzwa kabhoni fiber zvigadzirwa zvine hukama nepamusoro tembiricha kuramba resin.Izvi zvakafanana nenheyo yemapuranga emapuranga.Iyo yakanyanya tembiricha yekupikisa muganho we resin yave iyo yepamusoro muganho wepamusoro tembiricha kuramba yekabhoni fiber zvigadzirwa.
Mumamiriro ezvinhu akajairwa, kupisa kwakanyanya kweiyo resin matrix kunosvika 180C.Kana ikapfuura tembiricha iyi kwenguva yakareba, ichaita kuti resin matrix inyunguduke, izvo zvinokanganisa kuita kwekupedzisira kwechigadzirwa.
Mukuwedzera, kuitira kuti uwedzere kuvandudza kupisa kwekushisa kwepamusoro, chigadziko chemunwe chemuti chichasarudza matrix ane yakakwirira yekudzivirira kwekushisa, kureva, plastiki inokosha.Kana iwe uine matrix zvinhu zvine mabhenefiti epamusoro ekuita senge PEK nePPS, ipapo iyo kabhoni fiber zvigadzirwa zvinogadzirwa zvinozopokana neTembiricha inogona kusvika pamusoro pe20YC.Kana yakakwirira tembiricha kuramba ichidiwa, kabhoni-yakavakirwa kana ceramic simbi matrix inofanira kusarudzwa.Kuramba kwekushisa kwakadaro kunogona kuva nani.
