Izakhiwo ezibonakalayo zama-composites zilawulwa yimicu. Lokhu kusho ukuthi lapho ama-resins nemicu ehlanganisiwe, izakhiwo zawo zifana kakhulu nalezo zemicu. Idatha yokuhlola ikhombisa ukuthi izinto eziqinisiwe ze-fiber kuphela yizakhi ezithwala iningi lomthwalo. Ngakho-ke, ukukhethwa kwendwangu kubalulekile lapho uhlela izinhlaka eziyinhlanganisela.
Qala inqubo ngokunquma uhlobo lokuqiniswa oludingekayo kwiphrojekthi yakho. Umkhiqizi ojwayelekile angakhetha ezinhlotsheni ezintathu ezijwayelekile zokuqinisa: i-fiber ye-glass, i-carbon fiber kanye ne-kevlar® (i-aramid fiber). I-fiber yengilazi ivame ukuba ukukhetha kwendawo yonke, kuyilapho i-carbon fiber inikela ukuqina okuphezulu kanye nokuphikiswa okuphezulu kweKevlar®. Khumbula ukuthi izinhlobo zendwangu zingahlanganiswa ngama-laminates ukuze kufakwe ama-hybrid ticking anikeza izinzuzo zezinto ezingaphezu kweyodwa.
Ukuqiniswa kwe-fiberglass
I-fiberglass iyinto ejwayelekile. I-fiberglass iyisisekelo somkhakha wama-composites. Kusetshenziswe kwizicelo eziningi eziyinhlanganisela kusukela ngawo-1950s kanye nezakhiwo zayo ezibonakalayo ziqondwa kahle. I-fiberglass i-lightweight, inamandla alinganiselayo ama-Tensile futhi acindezele, angamelana nomonakalo kanye nokulayisha izikebhe, futhi kulula ukuyiphatha. Imikhiqizo evela ekukhiqizweni yaziwa ngokuthi yimikhiqizo eqinisiwe ye-fiberglass (frp). Kujwayelekile kuzo zonke izindawo zokuphila. Isizathu esenza sibizwe ngokuthi i-fiberglass yingoba lolu hlobo lokutholwa kwe-fiber lwenziwa ngokuncibilika quartz nezinye izinto zo-ore kumazinga okushisa aphezulu abe yi-slurry yengilazi. Base bekhipha ama-filaments aphezulu. Lolu hlobo lwefayibha lungenxa yokwakheka kwehlukile kunabaningi. Izinzuzo zokumelana nokushisa, ukumelana nokugqwala, amandla amakhulu. Ukufakelwa okuhle. Futhi i-carbon fiber inenkinga efanayo ingumkhiqizo u-brittle ngokwengeziwe. I-dectility empofu. Ungagqokile. Njengamanje, ukufakwa, ukulondolozwa kokushisa, ama-anti-corrosion kulula nezinye izinkambu eziningi zisebenzisa ipulasitiki yengilazi eqinisiwe.
I-fiberglass iyona esetshenziswa kakhulu kuyo yonke imihlombo etholakalayo. Lokhu kungenxa yezindleko zayo eziphansi kakhulu nezindawo ezinomzimba ezilinganiselayo. I-fiberglass ilungele kahle amaphrojekthi wansuku zonke nezingxenye ezingadingi ukufuna indwangu ye-fiber ngamandla amandla okufakwa nokuqina.
Ukwandisa izakhiwo zamandla ze-fiberglass, zingasetshenziswa ngama-epoxy resins futhi aphulukiswe kusetshenziswa amasu ajwayelekile wokukhanya. Ilungele kahle izinhlelo zokusebenza kwizimboni zezimoto, zasolwandle, zokwakha, zezokwakha, ze-aerospace izimboni futhi zivame ukusetshenziswa kwezimpahla zezemidlalo.
I-Aramid fiber ukuqiniswa kokuqina
I-ARAMID fiber iyindlela ephezulu yamakhemikhali anobuchwepheshe. Inamandla aphezulu, ukumelana okushisa okuphezulu, ukumelana nokugqwala, isisindo esikhanyayo nezinye izici, futhi kungenye yezinto ezibalulekile embonini yezokuvikela. Kunenqwaba yezicelo ezisetshenziswayo zemishini ye-bulletproof, imishini yendiza.
I-ARAMID Fibers ingenye yemicu yokwenziwa yamandla aphezulu aphezulu ukuthola ukwamukelwa embonini (i-FRP) eqinisiwe (FRP). Imicu ye-composite yebanga le-para-aramid iyi-lightweight, inamandla amahle kakhulu ashukumisayo, futhi kubhekwa njengokumelana kakhulu nomthelela kanye ne-abrasion. Izicelo ezijwayelekile zifaka phakathi ama-hull ama-kayaks kanye nezikebhe, amaphaneli endiza endiza kanye nemikhumbi yokucindezela, amagilavu avinjezelwe, ama-bullent vests nokuningi. I-ARAMID Fibers isetshenziswa nge-epoxy noma i-vinyl ester resens.
Ukuqiniswa kwe-carbon fiber
Ngokuqukethwe kwekhabhoni engaphezu kwama-90%, i-carbon fiber inamandla amakhulu okugcina embonini ye-FRP. Eqinisweni, futhi inamandla amakhulu acindezelayo namandla aguqukayo. Ngemuva kokucutshungulwa, le micu ihlanganiswa nokwakha ukuqiniswa kwe-carbon fiber okufana nezindwangu nezinkomo. Ukuqiniswa kwe-carbon fiber kunikeza amandla athile aphezulu nokuqina okuqondile, futhi kuvame ukubiza kakhulu kunezinye ukuqiniswa kwe-fiber.
Ukuze wandise izakhiwo zamandla ze-carbon fiber, kufanele isetshenziswe ngama-epoxy resins futhi aphulukiswe kusetshenziswa amasu ajwayelekile wokukhanya. Ilungele kahle izinhlelo zokusebenza zezimoto, zasolwandle kanye ne-aerospace futhi zivame ukusetshenziswa kwezimpahla zezemidlalo.
