Carbone Fibre Yashimangiye Imiterere ya Polymer
Carbone fibre ishimangirwa plastike ni ibikoresho byakozwe mugutunganya ibikoresho bya fibre fibre mucyerekezo runaka no gukoresha ibikoresho bya polymer bihujwe.Diameter ya fibre karubone iroroshye cyane, hafi micron 7, ariko imbaraga zayo ni nyinshi cyane.
Igice cyibanze kigizwe na karuboni fibre ishimangirwa nibikoresho ni karuboni fibre filament.Ibikoresho fatizo byibanze bya karubone ni prepolymer polyacrylonitrile (PAN), rayon, cyangwa peteroli.Amashanyarazi ya karubone noneho akozwe mumyenda ya karubone hakoreshejwe imiti nubukanishi kubice bya fibre.
Guhuza polymer mubisanzwe ni thermosetting resin nka epoxy.Ubundi thermosets cyangwa polimoplastike polymers rimwe na rimwe bikoreshwa, nka polyvinyl acetate cyangwa nylon.Usibye fibre ya karubone, ibiyigize birashobora kandi kuba birimo aramid Q, ultra-high-molecular uburemere polyethylene, aluminium, cyangwa fibre yibirahure.Ibiranga ibicuruzwa bya nyuma bya karubone birashobora kandi guhindurwa nubwoko bwinyongera bwinjijwe muri matrix.
Uburyo bwa Molding Uburyo bwa Carbone Fibre Yashimangiye Plastike
Ibicuruzwa bya fibre fibre biratandukanye cyane kubera inzira zitandukanye.Hariho uburyo bwinshi bwo gukora fibre fibre ikomezwa nibikoresho bya polymer.
1. Uburyo bwo Kurambika Intoki
Igabanyijemo uburyo bwumye (iduka ryateguwe mbere) nuburyo butose (fibre fibre na resin bifatanye kugirango ukoreshe).Kurambika intoki nabyo bikoreshwa mugutegura progaramu yo gukoreshwa muburyo bwa kabiri bwo gushushanya nko guhonyora.Ubu buryo niho impapuro z'imyenda ya karubone zomekwa kumurongo kugirango zibe ibicuruzwa byanyuma.Imbaraga nubukomezi bwibintu bivamo byahinduwe neza muguhitamo guhuza no kuboha imyenda.Ifumbire noneho yuzuzwa epoxy hanyuma igakira ubushyuhe cyangwa umwuka.Ubu buryo bwo gukora bukoreshwa kenshi mubice bidahangayitse, nkibifuniko bya moteri.
2. Uburyo bwo gushiraho icyuho
Kuri preregine yanduye, birakenewe gushira igitutu muburyo runaka kugirango yegere ifumbire no gukiza no kuyikora munsi yubushyuhe nigitutu runaka.Uburyo bw'isakoshi ya vacuum bukoresha pompe ya vacuum kugirango yimure imbere mumifuka ikora kugirango umuvuduko mubi uri hagati yumufuka nububiko ukora igitutu kuburyo ibikoresho byose byegeranye.
Hashingiwe kuburyo bwa vacuum bag, uburyo bwo gukora vacuum bag-autoclave bwakozwe nyuma.Autoclave itanga umuvuduko mwinshi nubushyuhe bukiza igice (aho gukira bisanzwe) kuruta uburyo bwa vacuum gusa.Igice nkiki gifite imiterere yoroheje, nziza yubuso bwiza, irashobora gukuraho neza ibyuka bihumeka (ibituba bizagira ingaruka cyane kumbaraga zigice), kandi ubwiza muri rusange buri hejuru.Mubyukuri, inzira yo gupakira vacuum isa niyya firime ya terefone igendanwa.Kurandura ikirere ni umurimo wingenzi.
3. Uburyo bwo guhunika
Gushushanyanuburyo bwo kubumba bufasha kubyara umusaruro mwinshi no kubyara umusaruro.Ubusanzwe ibishushanyo bikozwe mubice byo hejuru no hepfo, ibyo twita ifu yumugabo nububiko bwumugore.Uburyo bwo kubumba ni ugushira matel ikozwe muri preregs mububiko bwicyuma, kandi mugihe cyubushyuhe hamwe nigitutu runaka, matel irashyuha kandi igashyirwa mubutaka mu cyuho, ikagenda munsi yigitutu, hanyuma ikuzuza akavuyo, hanyuma hanyuma Kubumba no gukiza kugirango ubone ibicuruzwa.Nyamara, ubu buryo bufite igiciro cyambere cyambere ugereranije nubwa mbere, kubera ko ibumba risaba gukora neza cyane CNC.
4. Guhinduranya
Kubice bifite imiterere igoye cyangwa muburyo bwumubiri wimpinduramatwara, umuyaga wumuyaga urashobora gukoreshwa mugukora igice uhinduranya filament kuri mandel cyangwa intoki.Nyuma yo guhinduranya niwo muti wuzuye kandi ukureho mandel.Kurugero, amaboko ya tubular akoreshwa muri sisitemu yo guhagarika arashobora gukorwa hakoreshejwe ubu buryo.
5. Resin Transfer Molding
Kwimura ibishushanyo mbonera (RTM) nuburyo busanzwe bwo gushushanya.Intambwe zayo z'ibanze ni:
1. Shira umwenda mubi wa karubone wateguwe mubibumbano hanyuma ufunge ifumbire.
2. Shyiramo amavuta ya thermosetting resin muri yo, utere inda ibikoresho, kandi ukire.
Ibyiza bya Carbone Fibre Yashimangiye Polymer
(1) Imbaraga nyinshi hamwe na elastique nziza.
Imbaraga zihariye (ni ukuvuga igipimo cyingufu zingana nubucucike) bwa fibre karubone yikubye inshuro 6 icyuma ninshuro 17 za aluminium.Modulus yihariye (ni ukuvuga igipimo cya modulus ya Young nubucucike, nikimenyetso cyerekana ko ibintu byoroshye) yikubye inshuro zirenga 3 icyuma cyangwa aluminium.
Nimbaraga zidasanzwe, irashobora kwihanganira umutwaro munini wakazi.Umuvuduko mwinshi wakazi urashobora kugera kuri kg 350 / cm2.Mubyongeyeho, birashoboka cyane kandi birashobora kwihanganira kuruta F-4 nziza.
(2) Kurwanya umunaniro mwiza no kwihanganira kwambara.
Kurwanya umunaniro wacyo birarenze cyane ibya epoxy resin kandi birenze ibyuma.Graphite fibre irisiga amavuta kandi ifite coefficient ntoya yo guterana.Ingano yimyenda ni ntoya inshuro 5-10 ugereranije nibicuruzwa rusange bya asibesitosi cyangwa F-4.
(3) Imiyoboro myiza yubushyuhe no kurwanya ubushyuhe.
Carbone fibre ishimangirwa plastike ifite ubushyuhe bwiza bwumuriro, kandi ubushyuhe buterwa no guterana burundu.Imbere ntabwo byoroshye gushyuha no kubika ubushyuhe kandi birashobora gukoreshwa nkibikoresho bifunga kashe.Mu kirere, irashobora gukora neza mu bushyuhe bwa -120 ~ 350 ° C.Hamwe no kugabanya ibyuma bya alkali muri fibre karubone, ubushyuhe bwa serivisi burashobora kwiyongera.Muri gaze ya inert, ubushyuhe bwayo bushobora guhinduka bugera kuri 2000 ° C, kandi irashobora kwihanganira impinduka zikomeye mubukonje nubushyuhe.
(4) Kurwanya kunyeganyega kwiza.
Ntibyoroshye kumvikana cyangwa guhindagurika, kandi nigikoresho cyiza cyo kugabanya kunyeganyega no kugabanya urusaku.
Ibyiza bya CFRP
1. Uburemere bworoshye
Ibirahuri bya fibre gakondo byongerewe imbaraga byifashisha fibre yikirahure ikomeza hamwe na 70% fibre yibirahure (uburemere bwikirahure / uburemere bwose) kandi mubisanzwe bifite ubucucike bwibiro 0.065 kuri santimetero kibe.CFRP igizwe nuburemere bwa fibre 70% mubusanzwe ifite ubucucike bwa pound 0.055 kuri santimetero kibe.
2. Imbaraga Zirenze
Nubwo karuboni fibre ishimangirwa na polymers yoroheje, ibice bya CFRP bifite imbaraga nyinshi nuburemere bukabije kuburemere bwibice kuruta ibirahuri bya fibre.Ugereranije nibikoresho byuma, iyi nyungu iragaragara.
Ibibi bya CFRP
1. Igiciro kinini
Igiciro cyo gukora cya karuboni fibre ikomejwe irabujijwe.Ibiciro bya fibre ya karubone birashobora gutandukana cyane bitewe nuburyo isoko ryifashe ubu (itangwa nibisabwa), ubwoko bwa fibre fibre (aerospace vs urwego rwubucuruzi), nubunini bwa fibre bundle.Uhereye kuri pound-kuri-pound, fibre isukari ya karubone irashobora kuba ihenze inshuro 5 kugeza kuri 25 kuruta fibre.Itandukaniro rirakomeye cyane iyo ugereranije ibyuma na CFRP.
2. Imikorere
Izi ninyungu nibibi bya karuboni fibre yibikoresho.Biterwa na porogaramu.Fibre ya karubone irayobora cyane kandi fibre yibirahure irigaragaza.Ibicuruzwa byinshi bikoresha fiberglass aho gukoresha fibre ya karubone cyangwa ibyuma kuko bisaba gukingirwa gukomeye.Mubikorwa byingirakamaro, ibicuruzwa byinshi bisaba gukoresha fibre yibirahure.
Carbone Fibre Yashimangiye Gukoresha Plastike
Ikoreshwa rya karuboni fibre ishimangirwa polymer ni nini mubuzima, kuva mubice bya mashini kugeza ibikoresho bya gisirikare.
(1)nk'ugupakira
Caribre fibre ishimangirwa nibikoresho bya PTFE irashobora gukorwa mubintu birwanya ruswa, birinda kwambara, hamwe nubushyuhe bwo hejuru bwo gufunga impeta cyangwa gupakira.Iyo ikoreshejwe mugushiraho ikimenyetso gihamye, ubuzima bwa serivisi ni burebure, burenze inshuro 10 kurenza ubw'amapaki asibesitosi yinjijwe muri rusange.Irashobora gukomeza gukora kashe munsi yimitwaro no gukonjesha byihuse no gushyuha byihuse.Kandi kubera ko ibikoresho bitarimo ibintu byangirika, nta ruswa ishobora kugaragara ku cyuma.
(2)nk'ibisya
Gukoresha ibikoresho byayo byo kwisiga, birashobora gukoreshwa nkibikoresho, ibyuma, nimpeta za piston kubikorwa byihariye.Nkamavuta adafite amavuta kubikoresho byindege hamwe na majwi, ibyuma bidafite amavuta yo gukwirakwiza amashanyarazi ya moteri (kugirango birinde impanuka ziterwa no kumeneka kwa peteroli), impeta za piston zidafite amavuta kuri compressor, nibindi. gukoreshwa kandi nk'ibikoresho byo kunyerera cyangwa kashe mu nganda y'ibiribwa na farumasi ukoresheje inyungu zayo zitari uburozi.
(3) Nkibikoresho byubaka ikirere, indege, na misile.Yakoreshejwe bwa mbere mu gukora indege kugirango igabanye uburemere bwindege no kunoza imikorere yindege.Ikoreshwa kandi mubikoresho bya shimi, peteroli, ingufu z'amashanyarazi, imashini, nizindi nganda nkikimenyetso kizunguruka cyangwa gisubiza inyuma kashe cyangwa ibikoresho bitandukanye bya kashe bihamye.
Zhengxi ni umunyamwugauruganda rukora hydraulic mu Bushinwa, gutanga hejuru-quliatyimashini ikora hydraulicyo gukora ibicuruzwa bya CFRP.
