Yintoni i-carbon fiber eqoshiweyo?

I-carbon fiber echongiweyo yi-carbon fiber enqunyulwayo. Apha i-carbon fiber lutshintsho nje lokwakheka, ukusuka kwi-carbon fiber filament ukuya kwi-short filament, kodwa ukusebenza kwe-short-cut carbon fiber ngokwayo akutshintshanga. Kutheni ke ufuna ukusika i-filament short elungileyo?
Okokuqala, kufuneka siqale kwinkqubo yokubumba izinto ezidityanisiweyo. Ngokwesiqhelo i-carbon fiber filament kufuneka ilukwe ibe yilaphu le-carbon fiber okanye yenziwe ibe yi-carbon fiber prepreg, ize emva koko idlule kwi-inkqubo yokubumba, i-RTM, i-vacuum bagging, ii-hot press cans kunye nezinye iinkqubozibe ziintlobo ngeentlobo zeemveliso ze-carbon fiber composite. Kakade ke, kukwakho neenkqubo zokubumba ezingadingi zixhobo ziphakathi, ngokuthe ngqo nge-carbon fiber filament ukuze kubumbanwe, ezifana nokubumba nge-pultrusion, ukubumba nge-winding njalo njalo.
I-carbon fiber elukiweyo ibe yilaphu le-carbon fiber okanye yenziwe ibe yi-prepreg, yenza iimveliso, kukho ingxaki yendalo, ayilunganga ukunamathela kwi-mold. Ubukho be-mold kukunika imo kwi-composite material, i-mold inohlobo luni lwemilo, izinto zokugqibela ezidityanisiweyo nazo zinohlobo luni lwemilo. Nangona kunjalo, ukuba ilaphu le-carbon fiber okanye i-prepreg ayilungelani kakuhle ne-mold, imo ye-composite material ayifani ne-mold. Ukongeza, kwezinye iikona, ilaphu le-carbon fiber kulula ukulibopha, lenze umngxuma wendawo, nto leyo ekugqibeleni ibangela ukwehla kokusebenza kweemveliso ze-carbon fiber composite.
I-filament yekhabhoni engaphakathi kwilaphu lekhabhoni okanye i-prepreg ibotshelelwe kwaye akulula ukuyishukumisa. Ingakumbi kwimeko yoxinzelelo, ukuhamba kwe-resin kunye ne-carbon fiber filament kuphantsi kakhulu, okuya kuthi ekugqibeleni kubangele ubunzima bokubumba okanye ukwehla kokusebenza.
Okukhona ubude bufutshane, kokukhona buhamba kakuhleifayibha yekhabhoni eqoshiweyoKufuneka kwaziwe ukuba ukubumba ngenaliti yeyona ndlela isetyenziswa kakhulu nevuthiweyo kwinkqubo yokubumba ngeplastiki. Ukuba kusetyenziswa ekuvelisweni kwezinto ezidityanisiweyo, kuya kuba lutshintsho olukhulu.
Nangona kunjalo, ubude be-carbon fiber efutshane abunakuncipha, kuba ubude be-carbon fiber efutshane bufutshane, i-resin kunye ne-carbon fiber bonding ziya kuba buthathaka. Ngenxa yokuba i-bond phakathi kwe-resin kunye ne-carbon fiber ihambelana ngokuthe ngqo nendawo yoqhagamshelwano phakathi kwazo, ukuba ubude bufutshane, ngoko ke indawo yoqhagamshelwano iyancitshiswa ngokuqinisekileyo.
Emva koko kukho ukuphikisana apha, oko kukuthi, ukuphikisana phakathi kokusebenza kwefayibha emfutshane kunye nokuhambahamba. Okukhona ubude befayibha bude, kokukhona kulula ukusasazeka, ifayibha kunye nefayibha kulula ukubopha, kodwa okukhona udibaniso lwefayibha kunye neresin luqina, ukusebenza kwezinto ezidityanisiweyo kuya kuba phezulu. Okukhona ubude befayibha bufutshane, kokukhona kulula ukusasazeka, ngokuhamba kakuhle, kodwa i-fiber kunye ne-resin bond ibuthathaka kancinci. Indlela yokulinganisela oku kuphikisana, kufuneka ifundwe, ngesiqhelo, ukwenza iipellets zeplastiki eziqinisiweyo zefayibha emfutshane yekhabhoni, ubude bube yi-1-9mm.
Kukwakho nendlela yokuphucula amandla okubopha phakathi kwe-carbon fiber kunye ne-resin, eyi-agent yokulinganisa. Ngokwesiqhelo, kukho i-agent yokulinganisa phezu komphezulu we-carbon fiber.ifayibha yekhabhoniifektri, esetyenziselwa ukukhusela i-carbon fiber ekungcoleni kwenkqubo yokupakisha, ukudlulisa nokusebenza, kwaye kwelinye icala, isetyenziselwa ukudibanisa i-carbon fiber kunye ne-resin, kwaye idlala indima yokuphucula amandla okubopha.
Nangona kunjalo, le arhente yokulinganisa ubukhulu becala yenzelwe i-thermosetting resin. Uninzi lwee-resin ezisetyenziselwa ukwenza ii-pellets zii-thermoplastic resins, ngoko ke i-arhente yokulinganisa ubukhulu kufuneka ilungiswe. Enye kukutshisa i-arhente yokulinganisa yokuqala nokwenza umaleko omtsha we-arhente yokulinganisa ubukhulu. Enye kukutshisa i-arhente yokulinganisa yokuqala nokwenza umaleko omtsha we-arhente yokulinganisa ubukhulu; enye kukubuyisela i-arhente yokulinganisa ubukhulu kwakhona ngokusekelwe kwi-arhente yokulinganisa yokuqala, ebizwa ngokuba yi-secondary sizeing.
Ukongeza ekwenzeni iigranules zokubumba ngenaliti,ifayibha yekhabhoni eqoshiweyoinezinye iindlela zokusetyenziswa, njengokwenziwa nge-carbon fiber mat, okanye okwenziwe ngephepha le-carbon fiber. Ubude obufunekayo be-carbon fiber eqoshiweyo buya kuba bude kunobude be-fiber eqoshiweyo yee-granules.
Ukongeza, ukongeza kwiifayibha zekhabhoni ezinqunqwe ngokungacwangciswanga, kukwakho neefayibha zekhabhoni ezinqunqwe ngokudibeneyo. Le fayibha imfutshane ikwi-short cut ngaphambi kokuba i-carbon fiber itsalwe kuhlobo oluthile olumiselweyo, emva koko i-short-cut fiber ineempawu ze-bundle, equlathe ubungakanani be-resin iya kuba ngaphezulu kakhulu kunezinye iifayibha ezinqunqwe ngokudibeneyo.
