izindaba

Izakhiwo zomzimba zezinhlanganisela zibuswa yimicu. Lokhu kusho ukuthi lapho kuhlanganiswa ama-resin nemicu, izakhiwo zazo zifana kakhulu nezemicu ngayinye. Idatha yokuhlola ikhombisa ukuthi izinto eziqiniswe yi-fiber yizona ezithwala iningi lomthwalo. Ngakho-ke, ukukhetha indwangu kubalulekile lapho kuklanywa izakhiwo ezihlanganisiwe.
Qala inqubo ngokunquma uhlobo lokuqinisa oludingekayo kuphrojekthi yakho. Umkhiqizi ojwayelekile angakhetha ezinhlotsheni ezintathu ezivamile zokuqinisa: i-glass fiber, i-carbon fiber kanye ne-Kevlar® (i-aramid fiber). I-glass fiber ivame ukuba yisinqumo esivamile, kuyilapho i-carbon fiber inikeza ukuqina okuphezulu kanye nokumelana okukhulu kokuhuzuka kwe-Kevlar®. Khumbula ukuthi izinhlobo zendwangu zingahlanganiswa kuma-laminate ukuze kwakhiwe ama-hybrid stacks anikeza izinzuzo zezinto ezingaphezu kweyodwa.
Ukuqinisa i-Fiberglass
I-Fiberglass iyinto ejwayelekile. I-Fiberglass iyisisekelo semboni yezinto ezihlanganisiwe. Isetshenziswe ezinhlotsheni eziningi kusukela ngawo-1950 futhi izakhiwo zayo zomzimba ziyaqondakala kahle. I-Fiberglass ilula, inamandla okubamba aphakathi nendawo kanye nokucindezela, ingamelana nomonakalo kanye nomthwalo ojikelezayo, futhi kulula ukuyiphatha. Imikhiqizo evela ekukhiqizweni yaziwa ngokuthi imikhiqizo ye-fiberglass reinforced plastic (FRP). Ivamile kuzo zonke izindawo zokuphila. Isizathu sokuthi ibizwa ngokuthi i-fiberglass ukuthi lolu hlobo lwe-fiber filament lwenziwa ngokuncibilikisa i-quartz nezinye izinto ze-ore emazingeni okushisa aphezulu zibe yi-slurry yengilazi. Bese ikhishwa nge-filaments yesivinini esikhulu. Lolu hlobo lwe-fiber lubangelwa ukwakheka kwezinhlobo ezahlukene. Izinzuzo ukumelana nokushisa, ukumelana nokugqwala, amandla amakhulu. Ukushisa okuhle. Futhi i-carbon fiber inobubi obufanayo ukuthi umkhiqizo uyaphuka. Ukuqina okubi. Ayigugi. Okwamanje, ukushisa, ukulondolozwa kokushisa, ukulwa nokugqwala kulula kanye neminye imikhakha eminingi kusetshenziswa ipulasitiki yengilazi eqinisiwe.
I-Fiberglass iyona esetshenziswa kakhulu kuzo zonke izinhlanganisela ezitholakalayo. Lokhu kungenxa yokuthi ishibhile futhi inezakhiwo zomzimba ezilinganiselayo. I-Fiberglass ifaneleka kahle emisebenzini yansuku zonke kanye nezingxenye ezingadingi indwangu ye-fiber edinga kakhulu ukuze kube namandla nokuqina okwengeziwe.
Ukuze kukhuliswe amandla e-fiberglass, ingasetshenziswa nama-resin epoxy futhi ingalashwa kusetshenziswa amasu ajwayelekile e-lamination. Ifaneleka kahle ukusetshenziswa embonini yezimoto, yasolwandle, yokwakha, yamakhemikhali kanye neyezindiza futhi ivame ukusetshenziswa kwezemidlalo.

Ukuqinisa I-Aramid Fiber
I-Aramid fiber iyinhlanganisela yamakhemikhali yobuchwepheshe obuphezulu. Inamandla aphezulu, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, isisindo esincane nezinye izici, futhi ingenye yezinto ezibalulekile embonini yezokuvikela. Kunezinhlobo eziningi zezicelo emishinini engangeni zinhlamvu, imishini yokundiza.
Imicu ye-Aramid ingenye yemicu yokuqala yokwenziwa enamandla aphezulu eyamukelwa embonini yepulasitiki eqiniswe nge-fiber (FRP). Imicu ye-para-aramid yezinga elihlanganisiwe ilula, inamandla amahle kakhulu okudonseka, futhi ibhekwa njengemelana kakhulu nokushaywa nokuhuzuka. Ukusetshenziswa okuvamile kufaka phakathi ama-hull alula njenge-kayaks nezikebhe, amaphaneli e-fuselage endiza kanye nemikhumbi yokucindezela, amagilavu ​​​​amelana nokusika, amavesti avikela izinhlamvu nokuningi. Imicu ye-Aramid isetshenziswa nama-resin e-epoxy noma e-vinyl ester.

Ukuqinisa I-Carbon Fiber
Njengoba inokuqukethwe kwekhabhoni okungaphezu kuka-90%, i-carbon fiber inamandla aphezulu kakhulu okubamba izintambo embonini ye-FRP. Eqinisweni, inamandla amakhulu kakhulu okucindezela nokuguquguquka embonini. Ngemva kokucubungula, le micu ihlanganiswa ukuze yakhe ukuqinisa i-carbon fiber njengezindwangu kanye nokudonswa. Ukuqinisa i-carbon fiber kunikeza amandla aphezulu athile kanye nokuqina okuthile, futhi ngokuvamile kubiza kakhulu kunezinye ukuqinisa i-fiber.
Ukuze kukhuliswe amandla e-carbon fiber, kufanele isetshenziswe nama-epoxy resins futhi ingalapheka kusetshenziswa amasu ajwayelekile e-lamination. Ifaneleka kahle ukusetshenziswa kwezimoto, olwandle kanye nezindiza futhi ivame ukusetshenziswa kwezemidlalo.
