Iyo yekuumba dhizaini imwe chiyero che prepreg mukati mesimbi mold mhango ye mold, kushandiswa kwezvitsigiro zvine sosi yekupisa kuburitsa imwe tembiricha uye kudzvanywa kuitira kuti prepreg iri mugomba remuumbi inopfaviswa nekupisa, kuyerera kwekumanikidza, kuzere nekuyerera, kuzere ne mold cavity kuumba uye kurapa zvigadzirwa zvemaitiro nzira.
Thekuumba nzirainoratidzirwa nekudiwa kwekudziya mukuumbwa, chinangwa chekudziya ndechekuita iyo prepreg resin kupfavisa kuyerera, izere ne mold cavity, uye nekumhanyisa maitiro ekurapa eiyo resin matrix zvinhu. Munguva yekuzadza iyo mold cavity ne prepreg, kwete chete resin matrix inoyerera, asiwo inosimbisa zvinhu, uye iyoresinmatrix uye simbi inosimbisa inozadza zvikamu zvese zve mold cavity panguva imwe chete.
Chete resin matrix viscosity yakakura kwazvo, uye chisungo chakasimba zvakakwana kuti chiyerere nemafiber ekusimbisa, saka maitiro ekuumba anoda kuumbwa kukuru. Izvi zvinoda zviumbwa zvesimbi zvine simba rakawanda, kurongeka kwepamusoro, uye kusagadzikana kwekuora, uye zvinoda kushandiswa kwemichina yakakosha yekutsikirira kudzora tembiricha yekuumbwa kwekupora, kudzvanywa, kubata nguva, uye mamwe maitiro ekuita.
Iyo nzira yekuumba yemhando yepamusoro yekugadzira, kurongeka kwehukuru hwechigadzirwa, uye kupera kwepamusoro, kunyanya kune yakaomesesa dhizaini yezvakasanganiswa zvigadzirwa zvinogona kuumbwa kamwe chete, uye hazvizokanganisa kuita kwezvakasanganiswa zvigadzirwa. Chikanganiso chayo chikuru ndechekuti dhizaini yekugadzira uye kugadzira zvakanyanya kuoma, uye yekutanga mari yekudyara yakakura. Kunyange zvazvo nzira yekuumba ine zvikanganiso zviri pamusoro, iyo moldkuumba nziraichiri pachinzvimbo chakakosha mukuumbwa kwezvinhu zvakaumbwa.
1. Kugadzirira
Ita basa rakanaka re prepreg, molding tooling molds, nechoto chekuedza chidimbu chebasa rinotsigira, uye kuchenesa mold mukushandiswa kwekupedzisira kwe resin yakasara, uye tsvina, kuchengetedza mold yakachena uye yakatsetseka.
2. Kucheka uye kuisa prepregs
Ichagadzirwa kuita chigadzirwa checarbon fiber raw materials yakagadzirira, prepreg mushure mekupfuura ongororo, kuverenga nzvimbo yezvakagadzirwa, zvigadzirwa, huwandu hwemashiti, iyo yakaomeswa dhizaini nerusenzi yakawedzerwa kumusoro, panguva imwe chete pamusoro peiyo superposition yezvinhu zve pre-kudzvanywa, yakatsikirirwa muchimiro chenguva dzose, kunaka kweimwe nhamba yezvikamu zvakakora.
3. Kuumba nekurapa
Isa zvinhu zvakaturikidzana muforoma, uye panguva imwe chete mumukati epurasitiki airbags, vhara mold, iyo yose mumushini wekuumba, mukati mepurasitiki airbags pamwe nekumwe kusimba kunoramba kuripo, tembiricha yenguva dzose, isa nguva isingaperi kuti irape.
4. Kutonhodza nekudzikisa
Mushure menguva yenguva yekumanikidza kunze kweforoma kutanga kutonhora kuziva kwenguva yakati, uye wozovhura mold, demolding kunze kweziso kuti uchenese tooling mold.
5. Kugadzira kuumba
Mushure mekudzikisa chigadzirwa chinoda kucheneswa, nebhurashi resimbi kana bhurashi remhangura kukwenya kubva papurasitiki yasara, uye kufefeta nemhepo yakamanikidzwa, chigadzirwa chakaumbwa chinokwenenzverwa, kuitira kuti nzvimbo yacho iite mutserendende uye yakachena.
6. Nondestructive kuedza uye kuongorora kwekupedzisira
Kuedza kusingaparadzi uye kuongorora kwekupedzisira kwezvigadzirwa kunoitwa maererano nezvinodiwa zvemagwaro ekugadzira.
Kubva pakuzvarwa kwacarbon fiber composites, inogara ichiganhurwa nemutengo wekugadzira uye kurova kwekugadzira, haina kushandiswa muhuwandu hukuru. Sarudzo yekabhoni fiber yekugadzira mutengo uye kurova ndiyo nzira yekuumba, kabhoni fiber composite zvinhu molding process kune akawanda, akadai seRTM, VARI, hot press tank, oven curing prepreg (OOA), nezvimwewo, asi kune mabhodhoro maviri: 1, iyo molding cycle nguva yakareba; 2, mutengo unodhura (uchienzaniswa nesimbi nepurasitiki). Prepreg molding process, semhando yekuumba maitiro, inogona kuona kugadzirwa kwebatch uye kuderedza mutengo wekugadzira, uyo unowedzera uye unoshandiswa zvakanyanya.
