Inkqubo yokubumba sisixa esithile sokulungiselela ukungena kwingxobo yesinyithi yesikhunta, ukusetyenziswa kweepress ezinomthombo wobushushu ukuvelisa ubushushu kunye noxinzelelo oluthile ukuze i-prepreg kwingxobo yesikhunta ithanjiswe bubushushu, ukuhamba koxinzelelo, igcwele ukuhamba, izaliswe yi-mold cavity mold kunye neemveliso zokuphilisa zendlela yenkqubo.
Inkqubo yokubumba ibonakaliswa yimfuno yokufudumeza kwinkqubo yokubumba, injongo yokufudumeza kukwenza i-prepreg ekuthambiseni ukuhamba kwe-i-resin, ukuzalisa umngxuma wokubumba kunye nokukhawulezisa impendulo yokuphilisa kwezinto ze-resin matrix. Ngexesha lenkqubo yokuzalisa umngxuma wokubumba nge-prepreg, kungekuphela nje ukuhamba kwe-resin matrix, kodwa kunye nezinto zokuqinisa, kunye ne-resin matrix kunye neefayibha zokuqinisa zizalisa zonke iindawo zomngxuma wokubumba ngaxeshanye.
Kuphelai-resinI-matrix viscosity inkulu kakhulu, i-bond inamandla kakhulu, ukuze ihambe kunye neefayibha zokuqinisa, ngoko ke inkqubo yokubumba ifuna uxinzelelo olukhulu lokubumba, olufuna ii-mold zesinyithi ezinamandla aphezulu, ukuchaneka okuphezulu kunye nokumelana nokugqwala, kwaye ifuna ukusetyenziswa kwee-hot presses ezikhethekileyo ukulawula ubushushu bokubumba okuphilisayo, uxinzelelo, ixesha lokubamba kunye nezinye iiparameter zenkqubo.
Indlela yokubumba esebenza kakuhle kakhulu kwimveliso, ukuchaneka kobungakanani bemveliso, ukugqitywa komphezulu, ingakumbi kwisakhiwo esintsonkothileyo seemveliso zezinto ezidityanisiweyo ngokubanzi zinokubunjwa kube kanye, aziyi konakalisa ukusebenza kweemveliso zezinto ezidityanisiweyo. Ingxaki yayo ephambili kukuba uyilo lwesikhunta kunye nokuveliswa kwaso kuyinkimbinkimbi ngakumbi, utyalo-mali lokuqala lukhulu. Nangona inkqubo yokubumba ineziphene ezingentla, inkqubo yokubumba isikhunta isabambe indawo ebalulekileyo kwinkqubo yokubumba izinto ezidityanisiweyo.
1. Ukulungiselela
Yenza umsebenzi omhle weukulungiselela kwangaphambili, izixhobo zokubumba izixhobo, kunye nomsebenzi wokuvavanya isithando somlilo, kwaye ucoce isikhunta ekusebenziseni okokugqibela i-resin eseleyo, inkunkuma, ukugcina isikhunta sicocekile kwaye sigudile.
2. Ukusikwa nokubekwa kwezinto ezilungiselelwe kwangaphambili
Kuya kwenziwa imveliso yezinto ezikrwada ze-carbon fiber, emva kokudlula uphononongo, ubale indawo yezinto ezikrwada, izinto, inani lamaphepha, umaleko wezinto ezikrwada ngomaleko wempepho edityanisiweyo, kwangaxeshanye kwi-superposition yezinto ezikrwada, zicinezelwe kwimo eqhelekileyo, umgangatho wenani elithile lezinto ezixineneyo.
3, Ukubumba nokunyanga
Beka izinto ezisetyenzisiweyo ezifakwe kwi-mold, kwaye ngaxeshanye kwii-airbags zeplastiki zangaphakathi, vala i-mold, yonke ibe kumatshini wokubumba, ii-airbags zeplastiki zangaphakathi kunye noxinzelelo oluthile olungaguqukiyo, ubushushu obungaguqukiyo, misela ixesha elingaguqukiyo, ukuze iphele.
4, Ukupholisa kunye nokunciphisa
Emva kwexesha elithile loxinzelelo ngaphandle kwesikhunta, qaphela ukuba umkhuhlane uqala kancinci, uze uvule isikhunta, ukhuphe ngaphandle kweso ukuze ucoce isikhunta sezixhobo.
5, Ukucutshungulwa kokubumba
Emva kokuyisusa imveliso, kufuneka icocwe ngebrashi yentsimbi okanye ngebrashi yobhedu ukuze kukhuhlwe iplastiki eseleyo, kwaye ivuthelwe ngomoya ocinezelweyo, imveliso ebunjiweyo iyapholishwa, ukuze umphezulu ube bushelelezi kwaye ucoceke.
6, uvavanyo olungonakalisiyo kunye nokuhlolwa kokugqibela
Uvavanyo olungonakalisiyo kunye nokuhlolwa kokugqibela kweemveliso kwenziwa ngokweemfuno zamaxwebhu oyilo.
Uhlalutyo lwamanqaku obuchwephesha enkqubo yokubumba i-prepreg
Ukususela ekuzalweni kwee-carbon fiber composites, ibisoloko inqunyelwe ziindleko zokuvelisa kunye nempembelelo ye-beats zemveliso, kwaye ayisetyenziswanga ngobuninzi. Gqiba ngexabiso lemveliso ye-carbon fiber kwaye i-beat yinkqubo yokubumba,izinto ezidityanisiweyo zefayibha yekhabhoniInkqubo yokubumba kukho ezininzi, ezifana ne-RTM, i-VARI, iitanki ezishushu zokushicilela, i-oven curing prepreg (OOA), njl.njl., kodwa kukho iingxaki ezimbini: 1, ixesha lomjikelo wokubumba lide; 2, ixabiso libiza kakhulu (xa lithelekiswa neentsimbi kunye neeplastiki). I-Prepreg CompressionMolding, njengohlobo lwenkqubo yokubumba, inokuphumeza imveliso yebhetshi kwaye inciphise iindleko zemveliso, ezisetyenziswa kakhulu.
Inkqubo yokubumba i-Prepreg ibhekisa kubushushu, uxinzelelo, kwixesha elithile iya kusasazwa kwi-prepreg kwi-pre-shaped body compression molding. Isantya sokubumba sale nkqubo siyakhawuleza, iimfuno zezixhobo zilula, kulula ukuzisebenzisa, xa kuthelekiswa ne-hot press tank, i-VARI kunye ne-OOA process, imveliso ibalasele kuzo zombini umgangatho obonakalayo womphezulu, uzinzo oluhle, inkqubo kulula ukuyilawula.
▲Itshathi yokuhamba kwenkqubo yokubumba ngaphambi kokulungiselela
Izinto ezine zenkqubo yokubumba
1. Ubushushu kunye nokufana: kubonisa inqanaba lokuphendula phakathii-resinkwayeiarhente yokunyangakunye nokufana kwendawo yokusabela, ikakhulu kulawula umgangatho womphezulu wokubumba kunye nenqanaba lokuphilisa;
2. Uxinzelelo kunye nokufana: kubonisa isiphumo sokukhupha umoya kunye nokuhamba kwamanzi kwi-resin, kulawula umgangatho womphezulu wokubumba kunye neempawu zoomatshini;
3. Ubude bexesha lokunyanga: kubonisa inqanaba lokunyanga, ukuqinisekisa ukusebenza kakuhle kwemveliso;
4. Ubukhulu bomngxuma: bubonisa ubukhulu bemveliso, ngokweempawu ezikhethekileyo zezinto zefayibha yekhabhoni ngokwayo, yila ubukhulu bomngxuma obufanelekileyo.
Ukusebenza kwenkqubo
Ukulungiselela kwangaphambiliInkqubo yokubumba inokwenza ngokwethiyori nasiphi na isakhiwo semveliso, isakhiwo semveliso ukuba sinzima kakhulu, njenge-inverted buckle, indawo yeflange eninzi kakhulu, nto leyo ebangela ukwanda okukhulu kweendleko zesikhunta kunye nobunzima bemveliso, ngoko ke ulwakhiwo lweziqwenga ezintsonkothileyo ngakumbi alunamandla, kodwa sinokuba nokulungiswa kwesakhiwo okanye uyilo lweebhloko + izisombululo zokubopha ukuvelisa iindawo ezintsonkothileyo.
Itekhnoloji enxulumeneyo
1. Iteknoloji yokusika eneeleya ezininzi: Iiprepreg ezineeleya ezininzi zinqunyulwa ngexesha elinye; iiprepreg ezinee-engile ezahlukeneyo zinqunyulwa ngexesha elinye ukuphucula ukusebenza kakuhle kokusika.
2. Itekhnoloji yobushushu/yokuphuma kwe-hot-out: i-mold ifudunyezwa ngqo ukuya kubushushu bokunyanga, kwaye i-preform ifakwa kwi-mold kwaye icinezelwe kwimo, nto leyo enciphisa ixesha lokubumba kwaye inciphise ukusetyenziswa kwamandla.
3. Itekhnoloji yokubumba ngobungakanani obuyi-net: i-preform ibethelwa kubungakanani obuyi-net kuqala, ize ibekwe kwi-mold enobungakanani obuyi-net ukuze icolwe, nto leyo enciphisa inkqubo yokusika.
Ubunzima beNkqubo
Ubunzima ekuyileni ii-molds zeemveliso zesakhiwo esintsonkothileyo: Ukuba kukho ii-buckles ezininzi eziguqulweyo kunye neekona ezingalunganga kwiimveliso, kuya kwenza ii-molds zibe nzima ukuzenza, kwaye kwangaxeshanye, emva kokuba ii-molds zisetyenzisiwe ixesha elide, kuya kukhokelela ekunciphiseni ukuchaneka kokulungelelaniswa kweendawo zee-inserts. Ke ngoko, xa uyila imveliso, zama ukuphepha i-buckle eguqulweyo okanye i-angle engalunganga.
Qaphela: iindawo ezingaphandle zokugquma zeemfuno zomgangatho womphezulu wemveliso ziphezulu kakhulu, iindawo zezinto zefayibha yekhabhoni zeengxaki eziqhelekileyo zezi: iindawo zokuthungwa komphetho wemveliso amabala amhlophe; iingxaki zokuthungwa kwemveliso; imingxunya yomphezulu, ukungabikho kweengxaki zeglue, njalo njalo. Ukushwankathela izizathu, iarhente yokunyanga kwi-prepreg ayixutywanga ngokulinganayo okanye impendulo ayiphelelanga; ubushushu bokubumba abufani; ubushushu kunye noxinzelelo azikho endaweni; uyilo kunye nokucutshungulwa kokubumba azikho endaweni; inkqubo yokubumba ayilawulwa; ukubumbaiarhente yokukhululaisabela, njalo njalo.
