Anowanzo Kushandiswa Macomposites Uye Mabhenefiti Avo eFRP, RTM, SMC, uye LFI - Romeo RIM
Kune akasiyana siyana akajairwa macomposites kunze uko kana zvasvika kune mota uye dzimwe nzira dzekufambisa.FRP, RTM, SMC, uye LFI ndezvimwe zvinonyanya kuzivikanwa.Imwe neimwe ine yayo yakasarudzika seti yemabhenefiti, ichiita kuti ive yakakosha uye inoshanda kune yanhasi indasitiri zvinodiwa uye zviyero.Pazasi pane kukurumidza kutarisa kune aya macomposites uye izvo mumwe nemumwe wavo anofanira kupa.
Fiber-Reinforced Plastic (FRP)
FRP chinhu chinoumbwa chinosanganisira polymer matrix inosimbiswa nefibers.Aya mafibhi anogona kuve nenhamba yezvinhu zvinosanganisira aramid, girazi, basalt, kana kabhoni.Iyo polymer inowanzoita thermosetting purasitiki iyo ine polyurethane, vinyl ester, polyester, kana epoxy.
Mabhenefiti eFRP akawanda.Musanganiswa uyu unorambira ngura sezvo isingapinde mvura uye isina porous.FRP ine simba kune huremu reshiyo yakakwirira kupfuura simbi, thermoplastics, uye kongiri.Iyo inobvumira kune yakanaka single surface dimensional kushivirira sezvo ichigadzirwa zvinokwanisika uchishandisa 1 mold hafu.Fiber- Yakasimbiswa mapurasitiki anogona kuitisa magetsi ane mafirita akawedzerwa, anobata kupisa kwakanyanya zvakanaka, uye anobvumira akawanda anodiwa kupera.
Resin Transfer Molding (RTM)
RTM imwe nzira yekuumbwa kwemvura inoumbwa.A catalyst kana hardener inosanganiswa neresin yobva yabayiwa muforoma.Iyi mold ine fiberglass kana mamwe mafiber akaoma ayo anobatsira kusimbisa iyo composite.
Iyo RTM inoumbwa inobvumira mafomu akaoma uye maumbirwo akadai semakomba macurves.Iyo yakareruka uye yakasimba zvakanyanya, ine fiber kurodha kubva pa25-50%.yeRTM ine fiber yemukati.Kuenzaniswa nemamwe macomposites, RTM inokwanisika kugadzira.Uku kuumbwa kunobvumira kupedzwa mativi ese kunze nemukati nekugona kwemavara mazhinji.
Sheet Molding Compound (SMC)
SMC ndeye yakagadzirira-ku-mold yakasimbiswa polyester iyo inosanganisira kunyanya girazi faibha, asi mamwe mafiber anogona kushandiswa zvakare.Pepa remusanganiswa uyu rinowanikwa mumipumburu, inozotemwa kuita zvidimbu zvidiki zvinonzi "charges".Tambo refu dzekabhoni kana girazi dzakawaridzwa pakugeza resin.Iyo resin inowanzo sanganisira epoxy, vinyl ester kana polyester.
Hunhu hukuru hweSMC ndeyekuwedzera simba nekuda kwehurefu hwayo hwefiber, kana ichienzaniswa neakawanda kuumba makomisheni.Iyo inodzivirira corrosion, inokwanisika kugadzira, uye inoshandiswa kune dzakasiyana siyana tekinoroji zvinodiwa.SMC inoshandiswa mumashandisirwo emagetsi, pamwe nemotokari uye imwe tekinoroji yekufambisa.
Long Fiber Jekiseni (LFI)
LFI muitiro unobva pa polyurethane uye faibha yakachekwa ichibatanidzwa yobva yapfapfaidzwa mugomba remuvhu.Iyi mold cavity inogona kupendwa pamwe nekugadzira inodhura yakapedzwa chikamu kunze kwe mold.Kunyange ichiwanzo kufananidzwa neSMC setekinoroji tekinoroji, mabhenefiti makuru ndeokuti inopa mhinduro inodhura yezvikamu zvakapendwa, pamwe nekuve nemutengo wakaderera wekushandisa nekuda kwekudzika kwayo kuumbwa.Kune zvakare akati wandei mamwe matanho akakosha mukugadzira zvinhu zveLFI zvinosanganisira metering, kudurura, kupenda, uye kurapa.
LFI inozvirumbidza yakawedzera simba nekuda kwemafibhi ayo akareba akachekwa.Iyi komputa inogona kugadzirwa nemazvo, zvakangofanana, uye nekukurumidza kuita kuti idhure zvakanyanya kana ichienzaniswa nemamwe akawanda macompositi.Zvikamu zvakaumbwa zvinogadzirwa neLFI tekinoroji zvine huremu huremu uye zvinoratidzira zvakawanda-siyana zvichienzaniswa nemamwe maitiro echinyakare anoumbwa.Kunyange zvazvo LFI yakashandiswa kwechinguva ikozvino mumotokari uye mamwe mafambisi ekugadzira, inotanga kuwedzera kuremekedzwa mumusika wekuvaka dzimba zvakare.
Muchidimbu
Imwe neimwe yeakajairwa macomposites anoratidzwa pano ane ayo akasiyana mabhenefiti.Zvichienderana nemagumo anodiwa ekupedzisira echigadzirwa, imwe neimwe inofanirwa kunyatsotariswa kuti ione kuti ndeipi inonyatsoenderana nezvinodiwa nekambani.
Inzwa Wakasununguka Kutibata Nesu
Kana iwe uine mibvunzo nezve zvakajairika composite sarudzo uye zvakanakira, isu tinoda kutaura newe.PaRomeo RIM, tine chivimbo chekuti tinogona kupa mhinduro chaiyo kune zvaunoda zvekuumba, Bata nesu nhasi kuti uwane rumwe ruzivo.
