Ukuhlaziywa kanye nokusetshenziswa kwenqubo yokusonta ye-FRP

I-Fiber winding ingenye yezinqubo zokukhiqiza izinhlanganisela ze-resin matrix.Kunezinhlobo ezintathu eziyinhloko zama-winding: i-toroidal winding, i-plane winding kanye ne-spiral winding.Lezi zindlela ezintathu zinezici zazo, futhi indlela yokujika emanzi iyona esetshenziswa kakhulu ngenxa yezidingo zayo zemishini elula kanye nezindleko eziphansi zokukhiqiza.

Ngaphansi kwesimo sokulawula ukushuba kwesimo kanye nokuma komugqa okunqunywe kusengaphambili, i-fiber eqhubekayo noma indwangu efakwe ngeglue ye-resin ilinyazwa ngokuqhubekayo, ngokulinganayo futhi njalo esikhunjeni esiyinhloko noma ulwelwesi ngokusebenzisa imishini ekhethekile yokusonta, bese iqiniswa ngaphansi kwendawo ethile yokushisa ukuze indlela yokubumba impahla eyinhlanganisela yemikhiqizo ethile yokuma.Ukucubungula umdwebo wenqubo yokubumba i-fiber winding:

Kunezinhlobo ezintathu eziyinhloko zokusonta (FIG. 1-2): i-toroidal winding, i-planar winding kanye ne-spiral winding.Khalisa ezintweni eziqinisiwe zesikhunta kanye ne-axis ewumgogodla eduze kwama-degrees angu-90 (imvamisa engu-85-89) ekuqondeni kokugoqa okuqhubekayo ku-mandrel, izinto eziqinisiwe ezinomgogodla we-matrix kuzo zombili iziphetho ze-pole hole tangent futhi eqhubekayo. emazombezombe ekuqondeni indiza phezu mandrel, Kuvunguza isilonda kwagcizelela impahla futhi nge tangent emikhawulweni yomibili le mandrel, kodwa phezu Kuvunguza mandrel okuqhubekayo osongwayo phezu mandrel.

Ukuthuthukiswa kobuchwepheshe be-fiber winding kuhlobene eduze nokuthuthukiswa kwezinto zokuqinisa, izinhlelo ze-resin kanye nokusungulwa kwezobuchwepheshe.Nakuba ngo-Han Dynasty, inqubo yokwenza izinduku zezikhali ezifana ne-Gorilli ne-halberd yayingenziwa ngokufaka i-lacquer ngezigxobo ezinde zokhuni kanye no-bamboo obude nosilika oyindilinga, indlela yokwenza i-fiber winding ayizange ibe ubuchwepheshe bokukhiqiza izinto eziyinhlanganisela kuze kube yilapho 1950s.Ngo-1945, umshini wokuqala wokumisa isondo ongenawo entwasahlobo wakhiqizwa ngempumelelo ngobuchwepheshe be-fiber winding, futhi ngo-1947, kwasungulwa umshini wokuqala wokuhlanganisa i-fiber.Ngokuthuthukiswa kwemicu esebenza kahle kakhulu efana ne-carbon fibre kanye ne-aramong fibre kanye nokuvela komshini wokuvunguza olawulwa yi-microcomputer, inqubo yokusonta i-fiber, njengobuchwepheshe bokukhiqiza izinto ezibonakalayo obusebenza ngomshini, iye yathuthukiswa ngokushesha, futhi isetshenziswe cishe kuzo zonke izinkambu ezingenzeka. kusukela ngawo-1960.

Mayelana NATHI:hebeI-Yuniu Fiberglass Manufacturing Co., LTD.Sikhiqiza futhi sithengise imikhiqizo ye-e-type fiberglass, efana ne-fiberglass roving, usilika oqoshiwe we-fiberglass, i-fiberglass oqoshiwe wazizwa, i-fiberglass gingham, i-needed wazizwa, indwangu ye-fiberglass nokunye.Uma kukhona izidingo, sicela usithinte ngokukhululekile.

Ngokusho komehlukoethi chemisimo somzimba nesimo somzimba of resin substrate ngesikhathi sokugoqa, ukugoqa teamasu angahlukaniswa ngezindlela ezomile, ezimanzi kanye nezomile:

1. Yomile

Ukuvunguza okomile kusebenzisa itheyiphu ekhulelwe esiteji B ngemva kokukhuleliswa.Amapheshana angaphambi kokukhulelwa akhiqizwa futhi ahlinzekwa ezitshalweni ezikhethekile noma ama-workshops.Ukuze okomile, ibhande lentambo elicwiliswe ngaphambili kufanele lishiswe futhi lithambe emshinini wokusonta ngaphambi kokulinyazwa esikhunjeni esiwumongo.Izinga lentambo ye-prepreg ingalawulwa ngokunembile ngoba okuqukethwe kweglue, usayizi kanye nekhwalithi yetheyiphu kungatholwa futhi kuhlolwe ngaphambi kokusongwa.Ukusebenza kahle kokukhiqiza kokuvunguza okomile kuphakeme, isivinini sokuvunguza singafinyelela ku-100-200m/ min, futhi indawo yokusebenza ihlanzekile.Kodwa-ke, imishini yokusonta eyomile iyinkimbinkimbi futhi iyabiza, futhi amandla okugunda kwe-interlaminar emikhiqizo yokusonta aphansi.

2. Imanzi

Indlela yokusonta emanzi iwukuvunguza i-fiber esemoyeni ife ngqo ngaphansi kokulawula ukungezwani ngemva kwenqwaba kanye ne-glue yokucwilisa, bese iyaqina.Imishini yokusonta emanzi ilula, kodwa ngenxa yokuthi ibhande lentambo liyalimala ngokushesha ngemva kokucwiliswa, kunzima ukulawula nokuhlola okuqukethwe kweglue komkhiqizo ngesikhathi sokusonga.Phakathi naleso sikhathi, amaphutha afana nama-bubbles nama-pores akhiwa kalula emkhiqizweni lapho i-solvent kwisisombululo se-glue iqina, futhi ukungezwani nakho kunzima ukulawula ngesikhathi sokuvuthwa.Ngesikhathi esifanayo, izisebenzi zisebenza emkhathini oguquguqukayo we-solvent kanye nemvelo ye-flying fiber hair short, izimo zokusebenza zimpofu.

3. Indlela eyomile

Uma kuqhathaniswa nenqubo yokumanzisa, inqubo yokomisa kancane ingeza okokomisa endleleni kusukela ekucwilisweni kwefayibha kuya ekujikeni kuya ekubunjweni okuyisisekelo, futhi ngokuyisisekelo ixosha isincibilikis esixazululweni seglue setheyiphu yentambo.Ngokuphambene nenqubo eyomile, inqubo ye-semi-dry ayinciki kusethi eyinkimbinkimbi yemishini yokukhulelwa ngaphambi kokukhulelwa.Nakuba okuqukethwe kweglue komkhiqizo akulula ukulawula ngokunembile inqubo njengendlela emanzi futhi ngaphezu kweqoqo lemishini yokumisa ephakathi kunendlela emanzi, ukuqina kwabasebenzi kukhulu, kodwa i-bubble, i-porosity nezinye iziphambeko umkhiqizo uyancipha kakhulu.

Lezi zindlela ezintathu zinezici zazo, futhi indlela yokujika emanzi iyona esetshenziswa kakhulu ngenxa yezidingo zayo zemishini elula kanye nezindleko eziphansi zokukhiqiza.Izinzuzo kanye nokubi zezindlela ezintathu ezisongayo ziqhathaniswa kuThebula 1-1.

Ithebula 1-1 Isilinganiso sezindlela eziyizinkulungwane eziyishumi zezinqubo ezintathu zokusonta
