1. Intshayelelo yeNkqubo yokuNyula iThubhu

Ngale tutorial, uya kufunda indlela yokusebenzisa inkqubo yokujija ityhubhu ukwenza izakhiwo ze-tubular usebenzisa i-carbon fiber prepregs kumatshini wokujija ityhubhu, ngaloo ndlela uvelisa amandla aphezulu.iityhubhu ze-carbon fiber. Le nkqubo isetyenziswa ngokuqhelekileyo ngabavelisi bezinto ezidibeneyo.

Ukuba unqwenela ukuvelisa iityhubhu ezinamacala ahambelanayo okanye i-taper eqhubekayo, inkqubo yokuguqula i-tube yinto efanelekileyo. Konke okudingayo i mandrel yentsimbi yobungakanani obufanelekileyo kunye ne-oveni ukwenza iityhubhu zefayibha zekhabhoni ezilungiselelwe iimfuno zakho ezithile.

Kwiityhubhu zekhabhoni ezinokwakheka okuntsonkothileyo, ezinjengee-handlebars okanye ngaphezulu kwezakhelo ezintsonkothileyo zesakhelo se-tubular njengeefolokhwe zokuxhoma okanye iifreyimu zebhayisekile, itekhnoloji yokwahlula-mbunda yeyona ndlela ikhethwayo. Ngoku siza kubonisa indlela yokusebenzisa itekhnoloji yokwahlula-hlula ukuvelisa ezi ityhubhu ze-carbon fiber.

2. Ukulungiswa kunye nokuLungisa i-Metal Mandrels

• Ukubaluleka Metal Mandrels

Ngaphambi kokuqalisa inkqubo yokujija ityhubhu, inyathelo lokuqala kukulungiselela i-mandrels yentsimbi. Iimandrels zentsimbi kufuneka zihambelane nobubanzi bangaphakathi beetyhubhu, kwaye ukuguda komphezulu wabo kunye nonyango lwangaphambili olufanelekileyo lubalulekile. Ukongezelela, i-mandrels yentsimbi kufuneka iqhube unyango olufanelekileyo lwangaphambili, olufana nokucoca kunye nokusebenzisa i-arhente yokukhulula, ukwenza lula inkqubo yokudiliza elandelayo.

Ngethuba lenkqubo yokujija ityhubhu, i-metal mandrel idlala indima ebalulekileyo njengoko kufuneka ixhasei-carbon fiber prepregukuqinisekisa ukujikajika okugudileyo. Ngoko ke, ukulungiselela ubungakanani obufanelekileyo bentsimbi mandrel kwangaphambili kubalulekile. Ekubeni ifayibha carbon uya kwenzakala ngeenxa kumphezulu ongaphandle mandrel, ububanzi yangaphandle mandrel kufuneka utshatise ububanzi yangaphakathi ityhubhu carbon ifayibha kuveliswa.

• Ukusebenzisa i-arhente yokukhululwa

Iiarhente zokukhulula zinciphisa ukungqubana kwaye ziqinisekise ukudilizwa okugudileyo; kufuneka zisetyenziswe ngokulinganayo kumphezulu we-mandrel. Emva kokuba i-metal mandrel ilungisiwe, inyathelo elilandelayo kukusebenzisa i-arhente yokukhulula. Iiarhente zokukhululwa ezisetyenziswa ngokuqhelekileyo ziquka ioli ye-silicone kunye neparafini, enciphisa ngokufanelekileyo ingxabano phakathi kwe-carbon fiber kunye ne-metal mandrel.

Kwi-mandrel yentsimbi elungisiweyo, kufuneka siqinisekise ukuba icocekile kwaye ingaphezulu ngokugudileyo ukuze kube lula ukudilizwa kwemveliso. Emva koko, i-arhente yokukhulula kufuneka isetyenziswe ngokulinganayo kumphezulu we-mandrel.

3. Ukulungiswa kwe-carbon fiber prepreg

• Iintlobo kunye neenzuzo ze-prepreg

Kuphela i-carbon fiber prepregs ihlangabezana neemfuno eziphezulu zokuchaneka kokujija kunye nokulula ukuphatha. Nangona ezinye iintlobo zezixhobo zokuqinisa, ezifana ne-epoxy-impregnated dry fabrics, zinokuthi zisetyenziswe kwinkqubo yokuphefumula, ekusebenzeni, kuphela i-carbon fiber prepregs inokuhlangabezana neemfuno eziphezulu zokuchaneka kunye nokulula ukuphatha kule nkqubo.

Kule tutorial, sisebenzisa indlela ethile yokubeka i-prepreg yokuphucula ukusebenza kwetyhubhu.

• Prepreg Layup Design

Umaleko we-prepreg elukiweyo ubekwe kwicala langaphakathi lombhobho, ulandelwe ngamaleko amaninzi e-unidirectional prepreg, kwaye ekugqibeleni omnye umaleko we-prepreg elukiweyo uyasetyenziswa kwicala langaphandle lombhobho. Olu yilo lolwakhiwo lusebenzisa ngokupheleleyo izibonelelo zokuqhelaniswa nefayibha ye-prepreg elukiweyo kwi-0 ° kunye ne-90 ° izembe, iphucula ngokubonakalayo ukusebenza kombhobho. Uninzi lwepreg ye-unidirectional prepregs ebekwe kwi-0 ° axis inika ukuqina okugqwesileyo kwe-longitudinal kumbhobho.

4. Ukuhamba kwenkqubo yokwenziwa kombhobho

• Ukulungiselela kwangaphambili

Emva kokugqiba uyilo lwe-prepreg layup, inkqubo iqhubela phambili kwinkqubo yokuvalwa kombhobho. Ukusetyenzwa kwangaphambili kubandakanya ukususa ifilimu ye-PE kunye nephepha lokukhulula, kunye nokugcina iindawo ezifanelekileyo ezihambelanayo. Eli nyathelo libalulekile ekuqinisekiseni ukuqhubela phambili okugudileyo kweenkqubo zokujija okulandelayo.

• Iinkcukacha zenkqubo yokujija

Ngexesha lenkqubo yokucima, kubalulekile ukuqinisekisa ukuvuthwa okugudileyo kwe-prepregs, kunye ne-metal core shaft ibekwe ngokuzinzileyo kwaye isetyenziswe ngokunyanzeliswa ngokufanayo. I-metal core shaft kufuneka ibekwe ngokuthe gqolo kwincam yomaleko wokuqala we-prepregs, uqinisekise nokuba ukufakwa kwamandla.

Ngexesha lokujija, i-prepregs ezongezelelweyo zinokuthi zenzakaliswe ekupheleni ukuququzelela ukukhutshwa kwemveliso ngexesha lokudiliza.

• I-BOPP Film Ukusonga

Ukongeza kwi-prepreg, ifilimu yeBOPP inokusetyenziselwa ukusonga. Ifilimu ye-BOPP yonyusa uxinzelelo lokudibanisa, ikhusela, kwaye itywine i-prepreg. Xa usebenzisa ifilimu yokusonga ye-BOPP, kubalulekile ukuqinisekisa ukugcwala okwaneleyo phakathi kweeteyiphu.

5. Inkqubo ye-oven yokunyanga

• Ukunyanga Ubushushu kunye nexesha

Emva kokusongela ngokuqinileyo i-prepreg carbon fiber imathiriyeli eyomeleziweyo, ithunyelwa kwi-oveni ukuze inyangwe. Ulawulo lobushushu lubalulekile ngexesha lokunyanga kwi-oveni, njengoko iiprepregs ezahlukeneyo zineemeko ezahlukeneyo zokunyanga. Eli nyathelo libalulekile ekuqinisekiseni uzinzo lwemathiriyeli kunye nokuphucula ukusebenza.

Ngokusebenzisa indawo yobushushu obuphezulu kwi-oveni, icarbon fiberkunye ne-resin matrix isabela ngokupheleleyo, yenze into eyomeleleyo edibeneyo.

6. Ukususwa kunye nokuLungiswa

Emva kokususa ifilimu yokusonga iBOPP, imveliso ephilisiwe inokususwa. Ifilimu ye-BOPP inokususwa emva kokunyanga. Ukuba kuyimfuneko, ukubonakala kunokuphuculwa ngokusasaza kunye nokupenda. Ukuphucula ngakumbi ubuhle, iinkqubo ezongezelelweyo zokugqiba ezifana nesanti kunye nokupeyinta zingenziwa.
