Ngokunyuka okuqhubekayo kweemarike zesicelo, i-thermosetting resin esekelwe kwi-carbon fiber composites ibonisa ngokuthe ngcembe imida yabo, engakwazi ukuhlangabezana ngokupheleleyo neemfuno zesicelo esiphezulu kwimiba yokumelana nokunxiba kunye nokumelana nokushisa okuphezulu. Kule meko, imeko ye-thermoplastic resin esekelwe kwi-carbon fiber composites ikhula ngokuthe ngcembe, ibe ngamandla amatsha e-composites eziphambili. Kwiminyaka yakutshanje, itekhnoloji ye-carbon fiber yaseTshayina yenze uphuhliso olukhawulezayo, kwaye itekhnoloji yesicelo se-thermoplastic carbon fiber composite nayo iye yakhuthazwa ngakumbi.

Kuphononongo lwefayibha yekhabhoni eqhubekayo eyomelezwe kwi-thermoplastic preg, iindlela ezintathu zokusebenzisa i-thermoplastic carbon fiber zibonakaliswa ngokucacileyo.

1. Ukususela kwi-powder carbon fiber eqiniswe kwi-carbon fiber eqhubekayo eqiniswe
Iicomposites zeCarbon fibre thermoplastic zinokwahlulwa zibe ngumgubo wecarbon fiber, ifayibha yekhabhoni enqunqiweyo, i-unidirectional eqhubekayo ye-carbon fiber kunye nelaphu le-carbon fiber yokuqinisa. Ixesha elide i-fiber eyomeleziweyo, amandla amaninzi anikezelwa ngumthwalo osetyenzisiweyo, kwaye aphakamileyo amandla apheleleyo e-composite. Ke ngoko, xa kuthelekiswa nomgubo okanye ifayibha yekhabhoni enqunqiweyo eyomeleziweyo i-thermoplastic composites, i-carbon fibre eqhubekayo eyomeleziweyo ye-thermoplastic composites ineenzuzo zokusebenza ezingcono. Eyona nkqubo isetyenziswa kakhulu yokubumba inaliti e-China ngumgubo okanye i-carbon fiber eqiniweyo eqinisiweyo. Ukusebenza kweemveliso kunemida ethile. Xa i-carbon fiber eqhubekayo iqiniswe isetyenziswa, i-thermoplastic carbon fiber composite iya kungenisa indawo ebanzi yesicelo.

2. Uphuhliso ukusuka kwisiphelo esisezantsi se-thermoplastic resin ukuya kwi-medium end thermoplastic resin matrix.
I-Thermoplastic resin matrix ibonisa i-viscosity ephezulu ngexesha lenkqubo yokunyibilika, ekunzima ukungena ngokupheleleyo kwizinto ze-carbon fiber, kunye neqondo lokungena lihambelana ngokusondeleyo nokusebenza kwe-prepreg. Ukuze kuphuculwe ngakumbi ukumanzisa, iteknoloji yokuguqula i-composite yamkelwa, kwaye isixhobo sokuqala sokusasaza i-fiber kunye nezixhobo ze-resin extrusion zaphuculwa. Ngelixa ukwandisa ububanzi be-carbon fiber strand, ubuninzi be-extrusion eqhubekayo ye-resin yanda. Ukumanzisa kweresin ye-thermoplastic kwidimension ye-carbon fiber ngokucacileyo yaphuculwa, kwaye ukusebenza kwe-carbon fibre eqhubekayo yomeleza i-thermoplastic prepreg iqinisekisiwe ngokusebenzayo. I-resin matrix ye-carbon fiber thermoplastic composites eqhubekayo yandiswa ngempumelelo ukusuka kwi-PPS kunye ne-PA ukuya kwi-PI kunye ne-peek.

3. Ukusuka kwilabhoratri eyenziwe ngesandla ukuya kwimveliso yobuninzi obuzinzile
Ukususela kwimpumelelo yovavanyo oluncinci kwilabhoratri ukuya kwimveliso yobuninzi obuzinzile kwiworkshop, eyona nto iphambili kuyilo kunye nohlengahlengiso lwezixhobo zokuvelisa. Ingaba i-carbon fiber eqhubekayo yomeleza i-thermoplastic prepreg inokufikelela kwimveliso yobunzima obuzinzileyo ayixhomekeke kuphela kumndilili wemveliso yemihla ngemihla, kodwa kunye nomgangatho we-prepreg, oko kukuthi, ingaba umxholo we-resin kwi-prepreg uyalawuleka kwaye umlinganiselo ufanelekile, nokuba i-carbon fiber kwi-prepreg isasazwa ngokulinganayo kwaye ingene ngokucokisekileyo, kwaye nokuba umphezulu we-prepreg ugudile kwaye ubungakanani buchanekile.
