Nibaibirahuri or fibre ngufi, fiberglass or precio fibra de carbonebyongewe kuri matrike ya thermoplastique, ikigamijwe ahanini ni ukunoza imiterere nuburyo bwa polymer.Hariho itandukaniro ryinshi hagati yuburyo bubiri bwingenzi bwo gushimangira thermoplastique yo guterwa inshinge, uhereye kuburyo zahujwe na matrix ya polymer, kugeza kurwego rwimikorere bashobora gutanga, kandi form ya fibre imwe irashobora kuba myinshi Iyindi irakwiriye, ariko kuri igicucu, itandukaniro nyamukuru hagati ya fibre ngufi na ndende ni urwego rutunganyirizwa.
Gutunganya fibre ndende yashimangiye thermoplastique
Intego yibanze yo gutunganya fibre-fibre-yongerewe imbaraga ya termoplastique nugukomeza uburebure bwa fibre, ningirakamaro mugutezimbere imbaraga no gukomera.Kumeneka kwa fibre birashobora kugira ingaruka mbi kumiterere ya polymer igizwe kandi birashobora guhakana inyungu zo gukoresha imigozi ya fibre.Gukoresha nabi hamwe nibikoresho bidakwiriye hamwe nigishushanyo mbonera, cyangwa gukoresha ibikoresho bitunganijwe neza cyangwa ibikoresho, birashobora gutuma fibre imeneka.
Bitandukanye na fibre yaciwe ya plastiki ikomejwe, ibikoresho birebire bya fibre bisanzwe bikozwe na pultrusion.Inzira ikubiyemo kuramburaglass kugendayatewe hamwe na resmoplastique resin ikoresheje impregnation idasanzwe ipfa (kugirango ibisigarira bishobore kuzenguruka no guhambira fibre), hanyuma ugabanye imigozi yakuwe muri pellet, fibre muri pellet mubisanzwe ni 12mm Uburebure, burebure buranga fibre idafite imbaraga. , kandi ubu burebure ningirakamaro mugushoboza polymer kwimura neza stress kuri fibre ikomeye.
Iyo pellet zikoreshwa mugushushanya inshinge, fibre ndende irahuzwa kandi igakomeretsa cyane kugirango ikore skeleton y'imbere itanga imbaraga nubukomere.Ugereranije nibikoresho bigufi byuzuye fibre, ibihimbano bishimangirwa na fibre ndende, nibafibre fibrecyangwa fibre ya karubone, itanga imbaraga zingana-z-uburemere, ubukana bwingaruka, ubuzima bwumunaniro muremure, hamwe nubushyuhe bwagutse hamwe nuburinganire bwiza.
Ibi bikoresho biramba bitanga imikorere yuburyo bugereranywa nicyuma, nyamara biroroshye kuruta ibyuma, kandi birashobora kwifashisha inyungu zo gutunganya uburyo bwo guterwa inshinge.1k umwenda wa karuboneni ingirakamaro cyane nko gusimbuza ibyuma kuko biroroshye 70% kuruta ibyuma kandi byoroshye kuruta ibyuma.Aluminiyumu yoroshye 40%, kubwibyo fibre-fibre-fonctionnement irashobora gukoreshwa mugukora ibikoresho bisabwa mumodoka, ibicuruzwa bya siporo, ikirere, ibicuruzwa byabaguzi nibikoresho byinganda.Ibisigarira bisanzwe birimo polyamide (PA cyangwa nylon), polypropilene (PP), polyurethane ikaze ya termoplastique (ETPU), hamwe nubushyuhe bwo hejuru nka polyetheretherketone (PEEK), polyphthalamide (PPA), na polyamide.Ether imide (PEI) nibindi Mugihe thermoplastique iyariyo yose ishobora gushimangirwa na fibre, gusa bamwe batanga imikorere ihanitse kuko irashimangirwa neza.Mubyukuri, igice cya kirisiti-kirisiti gishimangirwa neza na fibre kuruta amorphous resin, bivuze ko gukomera kwabo n'imbaraga byiyongera cyane.
Gutunganya Ingingo ya Fibre ndende Yongerewe ibikoresho
Ugereranije nudusimba twahinduwe cyangwa granula yuzuye ifu yuzuye, kubumba fibre ndende ikomezwa hamwe ifite ibyo isabwa kubibumbano, amarembo, ibikoresho byo kubumba, hamwe no gushushanya igice.Inzira zikoreshwa mugutunganya ibyo bikoresho nazo ziratandukanye nizindi fibre ngufi ikomezwa na polymers.
Nkuko byavuzwe haruguru, kubungabunga fibre ni urufunguzo rwo gutsinda.Ibintu bishobora gutera uburebure bwa fibre harimo umuvuduko mwinshi hamwe nogosha kuva inshinge zatewe inshinge, nkuko bishobora gukurura inguni muburyo bwa sisitemu na runner.Kugumana uburebure bwa fibre, hari ingingo 3 zingenzi zitunganyirizwa kumenya:
1. Ibikoresho bishushanyije
Nubwo fibre ndende yambara bike kubibumbano kuruta fibre ngufi kuko hariho amaherezo ya fibre imeze nkurushinge ruto rugira ingaruka kubibumbano, ubwoko bumwe bwibyuma bibumbabumbwe bikwiranye na fibre ndende na fibre ngufi ikomezwa na polymers, ikunze kugaragara Iyambere ni icyuma cya P20, gishobora kwihanganira inshinge zirenga 100.000 ubudahwema.Niba bisabwa kuramba cyane (hejuru yinshuro 100.000 zinshinge), H13 chrome molybdenum ibyuma cyangwa A9 ibyuma bikomye ikirere ni amahitamo meza.Muri rusange, ibishishwa bikomye nuburyo bwiza bwo gutunganya fibre-fer-thermoplastique.Kubishushanyo byambarwa, birashobora kuvugururwa hakoreshejwe ikoranabuhanga rya electroplating.Ibishushanyo bya aluminiyumu birashobora no gukoreshwa niba prototypes igomba kubyazwa umusaruro kugirango yemeze igishushanyo.
2. Gukora ibikoresho
Fibre-fibre yongerewe imbaraga ya termoplastike irashobora gutunganywa hifashishijwe ibikoresho bisanzwe byo gutera inshinge hamwe na bike bidahoraho kugirango bihindure uburebure bwa fibre kandi byemere neza.Umuvuduko muke cyangwa intego rusange screw hamwe nimpeta idasubira inyuma yemerera gutembera kubusa hejuru birasabwa.Intego rusange-intego irashobora gukoreshwa, ariko nylon nozzles igomba kwirindwa kuko imiterere yikirahure cyamasaha (yagenewe kwirinda gutembera) igabanya umuvuduko, igatera ubwoya, kandi igatera fibre.Indi nama yo kugabanya kogosha ni ukwirinda ibishushanyo mbonera bya cone nozzle.Muri rusange, imyobo minini ya nozzle (byibura 5,6 mm) yorohereza kunyura hejuru ya fibre fibre-fer-resin.
Itegeko ryiza ryimashini iyo ari yo yose yo gutera ni ugutera 60-70% gusa yubunini.Ingano nini cyane yo kurasa yongera igihe cyo gusubiramo, mugihe ubunini buke bwo kurasa bivuze ko ibikoresho biguma muri barrale igihe kirekire, birashoboka ko byangirika.
3. Uburyo bwo gutunganya
Kubijyanye no gutunganya, ni ngombwa gukemura ibibazo bibiri: urupapuro rwintambara.Muri rusange, fibre ndende ishimangira ibice bya thermoplastique ifite uburambe buke kurenzafiberglassibice kubera ko guhinduranya filament bigabanya kugabanuka gutandukanye, ariko inshinge zakozwe mubice birebire bya fibre biracyahinduka, imwe mumpamvu nuko fibre itembera kumurongo ugana icyerekezo, nubwo byongera imbaraga mubice, bishobora gutera anisotropy.Kugirango wirinde guterana, ahandi hantu h'irembo cyangwa ibishushanyo mbonera birashobora gukoreshwa kugirango wirinde guhuza fibre ikabije mu bice bidasaba imbaraga nyinshi zo guhangana n'imitwaro yubatswe.
Komeza inyungu za fibre ndende
Gushushanya neza bya fibre ndende ishimangirwa bisaba guhindura bimwe mubisobanuro byogushushanya hamwe nibipimo bitunganyirizwa bikoreshwa kuri resin idashimangiwe hamwe na fibre ngufi.Kugirango ubone byinshi mubikoresho birebire bya fibre (bigura ibirenze ibikoresho bituzuye cyangwafiberglass yaciwe imirongo ikomezakubera imikorere yabo yo hejuru), imyitozo myiza igomba gukurikizwa mubikorwa byose.Niba fibre ndende yamenetse cyangwa idahuye kubera gufata nabi, gushushanya bipfa cyangwa ibikoresho byashizweho, imbaraga zabo nyinshi nibyiza byo gukomera bizagabanuka cyangwa bitakara.
