iimveliso

ICarbon fiber prepreg yenziwe ngefiber ende eqhubekayo kunye neresin enganyangekiyo. Yeyona fom isetyenziswa kakhulu ekrwada ukwenza imidibaniso esebenza kakhulu. Ilaphu le-Prepreg liqulunqwe luluhlu lwemiqulu yefiber eneresin efakwe ngaphakathi. I-fiber bundle iqala idityaniswe kumxholo ofunekayo kunye nobubanzi, kwaye emva koko iintsinga zihlulwe ngokulinganayo ngesakhelo sefiber. Ngelo xesha, i-resin ishushu kwaye ifakwe kwiphepha elingaphezulu kunye neliphantsi lokukhululwa. I-fiber kunye nephepha eliphezulu kunye nelisezantsi lokukhulula elifakwe nge-resin lingeniswa kwi-roller ngexesha elifanayo. I-fiber ifumaneka phakathi kwephepha eliphezulu kunye nelisezantsi lokukhulula, kwaye i-resin isasazwa ngokulinganayo phakathi kweefayili ngoxinzelelo lwe-roller. Emva kokuba i-resin efakwe kwi-fiber ipholile okanye yomisiwe, iqengqeleka ibe yimo ye-reel yi-coiler. I-resin efakwe kwi-fiber ejikelezwe liphepha eliphezulu kunye nelisezantsi lokukhulula libizwa ngokuba yi-carbon fiber prepreg. I-prepreg eqengqelekayo kufuneka ifakwe i-gelatin ukuya kwinqanaba lokusabela kancinci phantsi kobushushu obulawulwayo kunye nokufuma kwemekobume. Ngeli xesha, i-resin iqinile, ebizwa ngokuba yi-B-stage.

Ngokubanzi, xa usenza ilaphu le-carbon fiber prepreg, i-resin ithatha iindidi ezimbini. Enye kukufudumeza ngokuthe ngqo i-resin ukunciphisa i-viscosity yayo kunye nokuququzelela ukusabalalisa okufanayo phakathi kwemicu, ebizwa ngokuba yi-hot melt adhesive method. Enye kukunyibilikisa i-resin kwi-flux ukunciphisa i-viscosity, kwaye emva koko ishushu emva kokuba i-resin ifakwe kwi-fiber ukuze ivuse i-flux, ebizwa ngokuba yi-flux method. Kwinkqubo ye-adhesive ye-adhesive eshushu, umxholo we-resin kulula ukulawula, inyathelo lokumisa linokushiywa, kwaye akukho nto iseleyo, kodwa i-resin viscosity iphezulu, ekulula ukubangela i-fiber deformation xa ufaka i-fiber braids. Indlela yokunyibilikisa ineendleko eziphantsi zotyalo-mali kunye nenkqubo elula, kodwa ukusetyenziswa kwe-flux kulula ukuhlala kwi-prepreg, echaphazela amandla e-composite yokugqibela kwaye ibangele ukungcoliseka kwendalo.

Iintlobo zelaphu le-carbon fiber prepreg libandakanya ilaphu le-carbon fibre prepreg ye-unidirectional kunye nelaphu elilukiweyo le-carbon fiber prepreg. Ilaphu le-carbon fiber prepreg ye-unidirectional linamandla amakhulu kwicala lefayibha kwaye lidla ngokusetyenziselwa iipleyiti ezine-laminated zidityaniswe kumacala ahlukeneyo, ngelixa ilaphu elilukiweyo le-carbon fiber prepreg lineendlela ezahlukeneyo zokuluka, kwaye amandla alo aphantse afane kumacala omabini, ukuze angakwazi. zisetyenziswe kwizakhiwo ezahlukeneyo.

sinokubonelela ngecarbon fiber prepreg ngokweemfuno zakho
