Carbon yakakosha pakurarama kwezvinhu zvese zvipenyu, nekuti inoumba hwaro hwema organic molecules, uye ma organic molecules anoumba hwaro hwezvinhu zvese zvipenyu.Kunyangwe izvi pachazvo zvichishamisa, nekuvandudzwa kwekabhoni fiber, ichangobva kuwana zvinoshamisa maapplication muaerospace, civil engineering uye mamwe maitiro.Carbon fiber yakasimba, yakaoma uye yakareruka kupfuura simbi.Naizvozvo, kabhoni faibha yakatsiva simbi muzvigadzirwa zvepamusoro-soro senge ndege, mota dzemujaho nemidziyo yemitambo.
Carbon fibers anowanzo kusanganiswa nezvimwe zvinhu kugadzira macomposites.Chimwe chezvinhu zvinosanganiswa ndeye carbon fiber reinforced plastics (CFRP), iyo ine mukurumbira nekuda kwekusimba kwayo, kuoma uye kusimba kwepamusoro kune huremu reshiyo.Nekuda kwezvinodiwa zvakanyanya zvekabhoni fiber composites, vaongorori vakaita zvidzidzo zvakati kuti kuvandudza simba rekabhoni fiber composites, mazhinji acho akatarisana nehunyanzvi tekinoroji inonzi "fiber oriented dhizaini", iyo inovandudza simba nekugadzirisa kutarisisa. fibers.
Vatsvagiri vepaTokyo University yesainzi vakatora kabhoni fiber dhizaini nzira inogonesa kutaridzika uye ukobvu hwefiber, nekudaro ichiwedzera simba remapurasitiki akasimbiswa-fiber uye kugadzira mapurasitiki akareruka mukugadzira, zvichibatsira kugadzira ndege dzakareruka uye mota.
Nekudaro, iyo nzira yekugadzira ye fiber kutungamira haina zvikanganiso.Iyo fiber dhizaini dhizaini inongogonesa gwara uye inochengeta iyo fiber ukobvu yakagadziriswa, izvo zvinotadzisa kushandiswa kuzere kwemakanika zvivakwa zveCFRP.Dr ryyosuke Matsuzaki weTokyo University of Science (TUS) anotsanangura kuti tsvakiridzo yake inotarisisa pazvinhu zvakaumbwa.
Muchirevo chechinyorwa chino, Dr. Matsuzaki nevamwe vake Yuto Mori naNaoya kumekawa in tus vakaronga nzira itsva yekugadzira, iyo inogona panguva imwe chete optimize matangiro uye ukobvu hwefiber zvichienderana nenzvimbo yadzo muchimiro chakaumbwa.Izvi zvinovabvumira kuderedza huremu hweCFRP pasina kukanganisa simba rayo.Mhedzisiro yavo inoburitswa mujenari composite chimiro.
Maitiro avo ane matanho matatu: kugadzirira, kudzokorora, uye kugadzirisa.Mugadziriro yekugadzirira, kuongorora kwekutanga kunoitwa nekushandisa iyo inogumira chinhu nzira (FEM) kuona huwandu hwematanho, uye yemhando yehuremu yekuongorora inowanikwa kuburikidza nefiber guide dhizaini ye linear lamination modhi uye ukobvu shanduko modhi.Iyo fiber orientation inotarirwa nekutungamira kwekunetseka kukuru neiyo iterative nzira, uye ukobvu hunoverengerwa nehukuru hwekushushikana dzidziso.Chekupedzisira, shandura maitiro ekugadzirisa accounting yekugadzira, tanga wagadzira referensi "base fiber bundle" nzvimbo inoda kuwedzera simba, uye wozotarisa yekupedzisira gwara uye ukobvu hwehurongwa hwefiber bundle, ivo vanoparadzira pasuru kumativi ese e reference.
Panguva imwecheteyo, iyo yakagadziridzwa nzira inogona kuderedza huremu neinodarika 5%, uye kuita kuti mutoro wekutamisa hunyanzvi ukwire pane kushandisa fiber orientation chete.
Vatsvagiri vari kufadzwa nemhedzisiro iyi uye vanotarisira kushandisa nzira dzavo kuti vawedzere kudzikisa huremu hwechinyakare CFRP zvikamu mune ramangwana.Dr. Matsuzaki vakati nzira yedu yekugadzira inodarika kugadzirwa kwechinyakare kunogadzira ndege dzakareruka nemotokari, izvo zvinobatsira kuchengetedza simba uye kuderedza carbon dioxide emissions.
