Uhlalutyo kunye nokusetyenziswa kwenkqubo yokuvala i-FRP

I-Fiber winding yenye yeenkqubo zokwenziwa kwe-resin matrix composite.Zintathu iindlela eziphambili zokujija: i-toroidal winding, i-plane winding kunye ne-spiral winding.Ezi ndlela zintathu zineempawu zazo, kwaye indlela yokujika emanzi yeyona isetyenziswa kakhulu ngenxa yeemfuno zayo zezixhobo ezilula kunye neendleko eziphantsi zokwenziwa.

Phantsi kwemeko yokulawula uxinzelelo kunye nemilo yomgca emiselwe kwangaphambili, ifayibha eqhubekayo okanye ilaphu elifakwe kwiglue ye-resin linxeba ngokuqhubekayo, ngokulinganayo kwaye rhoqo kwi-core mold okanye i-lining ngokusebenzisa izixhobo ezikhethekileyo zokujija, kwaye emva koko iqiniswe phantsi kwemekobume ethile yobushushu ukuze ibe yintsholongwane. indlela yokubumba izinto ezidityanisiweyo zeemveliso ezithile zokumila.Ukwenziwa komzobo wenkqubo yokubumba ifayibha:

Kukho iindlela ezintathu eziphambili zokujija (FIG. 1-2): i-toroidal winding, i-planar winding kunye ne-spiral winding.Ring kwizinto eziqinisiweyo zokungunda kunye ne-axis engundoqo kufutshane ne-90 degrees (ngokuqhelekileyo i-85-89) kwicala lokujikeleza okuqhubekayo kwi-mandrel, izinto eziqiniweyo kunye nombindi we-matrix kuzo zombini iziphelo ze-pole hole tangent kunye nokuqhubekayo. ukujija kwicala lenqwelomoya kwi mandrel, inxeba spiral zomelezwa izinto kunye ne tangent kuzo zombini iziphelo mandrel, kodwa phezu spiral mandrel okuqhubekayo ukujija phezu mandrel.

Ukuphuhliswa kobuchwepheshe be-fiber winding ihambelana ngokusondeleyo nokuphuhliswa kwezinto zokuqinisa, iinkqubo ze-resin kunye nezinto ezisungulwe zobuchwepheshe.Nangona kwi-Han Dynasty, inkqubo yokwenza izixhobo ezifana ne-Gorilli kunye ne-halberd inokwenziwa ngokufaka i-lacquer eneepali ezinde zomthi kunye ne-bamboo emide kunye nesilika ejikelezayo, ubuchule bokujikeleza kwe-fiber abuzange bube bubuchwepheshe bokwenza izinto ezidibeneyo de 1950s.Ngomnyaka we-1945, isixhobo sokuqala sokumisa ivili le-spring-free saveliswa ngempumelelo yi-fiber winding technology, kwaye ngo-1947, umatshini wokuqala wokuvala i-fiber wasungulwa.Ngophuhliso lwemicu ephezulu yokusebenza njengefayibha yekhabhoni kunye nefayibha ye-aramong kunye nenkangeleko yomatshini wokujija olawulwa yi-microcomputer, inkqubo yokujija ifayibha, njengobuchwephesha bokwenza izinto ezixutywe ngoomatshini, iye yaphuhliswa ngokukhawuleza, kwaye isetyenziswe phantse kuzo zonke iinkalo ezinokwenzeka. ukusukela ngoo-1960.

Ngathi:hayiYuniu Fiberglass Manufacturing Co., LTD.Ubukhulu becala sivelisa kwaye sithengise iimveliso ze-e-type fiberglass, ezifana ne-fiberglass roving, i-fiberglass yesilika enqunqwe, i-fiberglass eqoshiwe, i-fiberglass gingham, i-naliti evakalelwa, ilaphu le-fiberglass njalo njalo.Ukuba kukho naziphi na iimfuno, nceda uqhagamshelane nathi ngokukhululekileyo.

Ngokokwahlukakwi chemimo ehambelanayo neyomzimba of resin substrate ngexesha lokusonga, ukusonga teIindlela zinokwahlulwa zibe ziindlela ezomileyo, ezimanzi kunye nezomileyo:

1. Yomile

I-Dry winding ithatha iteyiphu e-pre-pregnated kwinqanaba B emva kokukhulelwa kwangaphambili.Imicu ekhulelweyo iyenziwa kwaye ibonelelwe ngezityalo ezikhethekileyo okanye iindibano zocweyo.Ukujija okomileyo, ibhanti yomsonto esele ifakwe ngaphambili kufuneka ifudunyezwe kwaye ithambe kumatshini wokujija phambi kokuba unxenxelwe kukungunda okungundoqo.Umgangatho we-prepreg yarn unokulawulwa ngokuchanekileyo kuba umxholo weglue, ubungakanani kunye nomgangatho we-tape unokubonwa kwaye uhlolwe ngaphambi kokujika.Ukusebenza kwemveliso yomoya owomileyo kuphezulu, isantya somoya sinokufikelela kwi-100-200m / min, kwaye indawo yokusebenza icocekile.Nangona kunjalo, izixhobo zokujija ezomileyo zintsonkothile kwaye ziyabiza, kwaye amandla e-interlaminar shear yeemveliso zokujija aphantsi.

2. Imanzi

Indlela yokujija emanzi kukuvuthuza ifayibha kwi-core die ngqo phantsi kolawulo loxinzelelo emva kwe-bundle kunye ne-glue yediphu, kwaye emva koko iqine.Izixhobo zokujija ezimanzi zilula, kodwa ngenxa yokuba ibhanti yomsonto linxeba ngokukhawuleza emva kokuditshwa, kunzima ukulawula kunye nokuhlola umxholo weglue wemveliso ngexesha lenkqubo yokujika.Okwangoku, iziphene ezinjengamaqamza kunye nama-pores zenziwe ngokulula kwimveliso xa i-solvent kwisisombululo seglue iqinisiwe, kwaye ukuxhatshazwa kunzima ukulawula ngexesha lokuhamba.Ngelo xesha, abasebenzi basebenza kwi-solvent volatile atmosphere kunye nokusingqongileyo kwe-flying fiber hair short, iimeko zokusebenza zihluphekile.

3. Indlela eyomileyo

Xa kuthelekiswa nenkqubo emanzi, inkqubo eyomileyo yongeza isixhobo sokumisa endleleni ukusuka kwifayibha dipping ukuya ekujikeni ukuya kubumba ongundoqo, kwaye ngokusisiseko ugxotha isinyibilikisi kwisisombululo seglu kwitape yomsonto.Ngokuchaseneyo nenkqubo eyomileyo, inkqubo ye-semi-dry ayixhomekeke kwisethi enzima yezixhobo zokukhulelwa kwangaphambili.Nangona umxholo weglu kwimveliso akukho lula ukulawula ngokuchanekileyo kwinkqubo njengendlela emanzi kwaye ngaphezu kweseti yezixhobo zokomisa eziphakathi kunendlela emanzi, ukuqina kwabasebenzi kukhulu, kodwa i-bubble, i-porosity kunye nezinye iziphene imveliso iyancipha kakhulu.

Ezi ndlela zintathu zineempawu zazo, kwaye indlela yokujika emanzi yeyona isetyenziswa kakhulu ngenxa yeemfuno zayo zezixhobo ezilula kunye neendleko eziphantsi zokwenziwa.Iinzuzo kunye nokungonakali kweendlela ezintathu zokujika zifaniswa kwiThebhile 1-1.

Itheyibhile 1-1 Umyinge weendlela ezimawaka alishumi zeenkqubo ezintathu zokujija
