Inqubo yokubumba inani elithile lokulungiselela ukungena emgodini wensimbi wesikhunta, ukusetshenziswa kwemishini yokucindezela enomthombo wokushisa ukukhiqiza izinga lokushisa elithile kanye nengcindezi ukuze i-prepreg emgodini wesikhunta ithanjiswe ukushisa, ukugeleza kwengcindezi, ukugeleza okugcwele, okugcwele ukubumba kwesikhunta kanye nemikhiqizo yokwelapha yendlela yenqubo.
Inqubo yokubumba ibonakala ngesidingo sokushisa enkambisweni yokubumba, inhloso yokushisa ukwenza i-prepreg ekuthambiseni ukugeleza kwe-i-resin, ukugcwalisa umgodi wesikhunta futhi kusheshiswe ukusabela kokwelapha kwezinto ze-resin matrix. Ngesikhathi senqubo yokugcwalisa umgodi wesikhunta nge-prepreg, akugcini nje ngokugeleza kwe-resin matrix, kodwa futhi nezinto zokuqinisa, kanye ne-resin matrix kanye nemicu yokuqinisa kugcwalisa zonke izingxenye zomgodi wesikhunta ngesikhathi esisodwa.
Kuphelai-resini-matrix viscosity inkulu kakhulu, isibopho sinamandla kakhulu, ukuze sihambisane nemicu yokuqinisa, ngakho-ke inqubo yokubumba idinga ingcindezi enkulu yokubumba, edinga isikhunta sensimbi esinamandla aphezulu, ukunemba okuphezulu kanye nokumelana nokugqwala, futhi idinga ukusetshenziswa kwemishini ekhethekile yokucindezela okushisa ukulawula izinga lokushisa lokubumba okuphilisayo, ingcindezi, isikhathi sokubamba kanye neminye imingcele yenqubo.
Indlela yokubumba esebenza kahle kakhulu ekukhiqizeni, ukunemba kosayizi womkhiqizo, ukuqeda ubuso, ikakhulukazi isakhiwo esiyinkimbinkimbi semikhiqizo yezinto ezihlanganisiwe ngokuvamile ingabunjwa kanye, ngeke ilimaze ukusebenza kwemikhiqizo yezinto ezihlanganisiwe. Iphutha layo eliyinhloko ukuthi ukwakheka kwesikhunta kanye nokukhiqizwa kuyinkimbinkimbi kakhulu, ukutshalwa kwezimali kokuqala kukhulu. Nakuba inqubo yokubumba inamaphutha angenhla, inqubo yokubumba isikhunta isathatha indawo ebalulekile enqubweni yokubumba izinto ezihlanganisiwe.
1. Ukulungiselela
Yenza umsebenzi omuhle weukulungiselela, izikhunta zamathuluzi okubumba, ngomshini wokuhlola isithando somlilo, bese uhlanza isikhunta ngokusetshenziswa kokugcina kwe-resin esele, udoti, ukuze kugcinwe isikhunta sihlanzekile futhi sibushelelezi.
2. Ukusika nokubeka izinto ezilungiselelwe kusengaphambili
Kuzokwenziwa umkhiqizo wezinto zokusetshenziswa ze-carbon fiber ezilungele, zilungiswe ngemuva kokudlula isibuyekezo, zibale indawo yezinto zokusetshenziswa, izinto zokwakha, inani lamashidi, ungqimba lwezinto zokusetshenziswa ngengqimba yempepho ehlanganisiwe, ngesikhathi esifanayo endaweni yokufakwa kwezinto zokusetshenziswa kwengcindezi yangaphambi kokucindezela, ecindezelwe ngesimo se-regular, ikhwalithi yenani elithile lezinto ezixineneyo.
3, Ukubumba nokwelapha
Faka izinto zokusetshenziswa ezihlanganisiwe esikhumbeni, futhi ngesikhathi esifanayo ezikhwameni zomoya zangaphakathi zepulasitiki, vala isikhunta, sonke emshinini wokubumba, izikhwama zomoya zangaphakathi zepulasitiki kanye nokucindezela okuthile okungaguquki, izinga lokushisa elingaguquki, setha isikhathi esingaguquki, ukuze siqine.
4, Ukupholisa nokususa ukungcola
Ngemva kwesikhathi sokucindezela ngaphandle kwesikhunta, qala uqonde ukuthi umkhuhlane ungakanani isikhathi esithile, bese uvula isikhunta, ukhiphe ngaphandle kweso ukuze uhlanze isikhunta samathuluzi.
5, Ukucubungula ukubunjwa
Ngemva kokususa umkhiqizo, umkhiqizo udinga ukuhlanzwa, ngebhulashi lensimbi noma ibhulashi lethusi ukuze kukhuhlwe ipulasitiki esele, bese uvuthelwa ngomoya ocindezelwe, umkhiqizo obunjiwe uyapholishwa, ukuze indawo ibushelelezi futhi ihlanzeke.
6. Ukuhlolwa okungabhubhisi kanye nokuhlolwa kokugcina
Ukuhlolwa okungonakalisi kanye nokuhlolwa kokugcina kwemikhiqizo kwenziwa ngokwezidingo zemibhalo yokuklama.
Ukuhlaziywa kwamaphuzu obuchwepheshe enqubo yokubumba ye-prepreg
Kusukela ekuzalweni kwezinhlanganisela ze-carbon fiber, ibilokhu inqunyelwe yizindleko zokukhiqiza kanye nomthelela wokushaya kokukhiqiza, futhi ayizange isetshenziswe ngobuningi obukhulu. Nquma ukuthi izindleko zokukhiqiza i-carbon fiber kanye nokushaya kuyinqubo yokubumba,izinto ezihlanganisiwe ze-carbon fiberInqubo yokubumba kunezinhlobo eziningi, njenge-RTM, i-VARI, amathangi okucindezela ashisayo, i-oven curing prepreg (OOA), njll., kodwa kunezinkinga ezimbili: 1, isikhathi somjikelezo wokubumba side; 2, intengo iyabiza (uma kuqhathaniswa nezinsimbi namapulasitiki). I-Prepreg CompressionMolding, njengohlobo lwenqubo yokubumba, ingafeza ukukhiqizwa kweqembu futhi inciphise izindleko zokukhiqiza, okusetshenziswa kabanzi kakhulu.
Inqubo yokubumba i-Prepreg ibhekisela ekushiseni, ingcindezi, esikhathini esithile izosakazwa kusengaphambili ekubumbeni kokucindezela komzimba okubunjwe ngaphambilini. Ijubane lokubumba lale nqubo liyashesha, izidingo zemishini zilula, kulula ukuzisebenzisa, uma kuqhathaniswa nethangi lokucindezela elishisayo, inqubo ye-VARI kanye ne-OOA, umkhiqizo muhle kakhulu kokubili ngekhwalithi ebonakalayo ebusweni, ukuzinza okuhle kobukhulu, inqubo kulula ukuyilawula.
▲Ishadi lokugeleza kwenqubo yokubumba ngaphambi kokukhulelwa
Izinto ezine zenqubo yokubumba
1. Izinga lokushisa kanye nokufana: okubonisa izinga lokusabela phakathii-resinfuthii-ejenti yokwelaphakanye nokufana kwesikhundla sokusabela, okulawula kakhulu ikhwalithi yobuso bokubumba kanye nezinga lokwelapha;
2. Ingcindezi kanye nokufana: okubonisa umphumela wokukhishwa komoya kanye nokugeleza kwe-resin, okulawula ikhwalithi yobuso bokubumba kanye nezakhiwo zemishini;
3. Ubude besikhathi sokulungisa: okubonisa izinga lokulungisa, ukuqinisekisa ukusebenza kahle kokukhiqiza;
4. Ubukhulu bomgodi wesikhunta: okubonisa ubukhulu bomkhiqizo, ngokwezici ezikhethekile zezinto ze-carbon fiber uqobo, klama ubukhulu bomgodi obufanele.
Ukusebenza kwenqubo
Ukulungiselela kusengaphambiliinqubo yokubumba ingakhiqiza ngokombono noma yisiphi isakhiwo somkhiqizo, isakhiwo somkhiqizo uma siyinkimbinkimbi kakhulu, njenge-buckle eguquliwe, indawo ye-flange eningi kakhulu, okuholela ekwandeni okukhulu kwezindleko zesikhunta kanye nobunzima bokukhiqiza, ngakho-ke isakhiwo sezingcezu eziyinkimbinkimbi kakhulu sokusebenza asinamandla, kodwa singaba nokwenza kahle kwesakhiwo noma ukwakheka kwebhulokhi + izixazululo zokubopha ukukhiqiza izingxenye eziyinkimbinkimbi.
Ubuchwepheshe Obuhlobene
1. Ubuchwepheshe Bokusika Obunezingqimba Eziningi: Ama-prepreg anezingqimba eziningi asikwa ngesikhathi esisodwa; ama-prepreg anezingqimba ezahlukene asikwa ngesikhathi esisodwa ukuze kuthuthukiswe ukusebenza kahle kokusika.
2. Ubuchwepheshe bokushisa/bokushisa: isikhunta sishiswa ngqo ekushiseni okuphola, bese i-preform ifakwa kusikhunta bese icindezelwa ibe sesimweni, okunciphisa isikhathi sokubumba futhi kunciphisa ukusetshenziswa kwamandla.
3. Ubuchwepheshe bokubumba ngosayizi we-net: i-preform ishaywa ibe ngosayizi we-net kuqala, bese ifakwa ku-mold yosayizi we-net ukuze iphole, kuncishiswe inqubo yokusika.
Ubunzima Benqubo
Ubunzima ekuklameni izikhunta zemikhiqizo yesakhiwo esiyinkimbinkimbi: Uma kunezikhunta eziningi eziguquliwe kanye namakhona angemihle emikhiqizweni, kuzokwenza izikhunta zibe nzima kakhulu ukuzikhiqiza, futhi ngesikhathi esifanayo, ngemva kokuba izikhunta zisetshenziswe isikhathi eside, kuzoholela ekwehleni kokunemba kokuhlanganiswa kwesimo kwezikhunta. Ngakho-ke, lapho uklama umkhiqizo, zama ukugwema i-buckle eguquliwe noma i-engeli engemihle.
Qaphela: izingxenye zangaphandle zokumboza zezidingo zekhwalithi yomkhiqizo ziphezulu kakhulu, izingxenye zezinto ze-carbon fiber zezinkinga ezivamile yilezi: izingxenye zokuthungwa komkhiqizo amabala amhlophe; izinkinga zokuthungwa komkhiqizo ezingcolile; imigodi engaphezulu, ukuntuleka kwezinkinga zeglue, njalo njalo. Ukuze sifingqe izizathu, i-ejenti yokwelapha ku-prepreg ayixubene ngokulinganayo noma ukusabela akuphelele; izinga lokushisa lesikhunta alifani; izinga lokushisa kanye nengcindezi akusekho endaweni; ukwakheka kwesikhunta kanye nokucubungula akusekho endaweni; inqubo yokubumba ayilawulwa; isikhuntai-ejenti yokukhululauyasabela, njalo njalo.
