Izici ezingokomzimba zezinhlanganisela zilawulwa imicu. Lokhu kusho ukuthi lapho ama-resin nemicu kuhlanganiswa, izakhiwo zabo zifana kakhulu nalezo zemicu ngayinye. Idatha yokuhlola ibonisa ukuthi izinto eziqiniswe ngefayibha yizingxenye ezithwala iningi lomthwalo. Ngakho-ke, ukukhetha kwendwangu kubalulekile lapho uklama izakhiwo ezihlanganisiwe.
Qala inqubo ngokunquma uhlobo lokuqinisa oludingekayo kuphrojekthi yakho. Umkhiqizi ojwayelekile angakhetha ezinhlotsheni ezintathu ezijwayelekile zokuqinisa: i-glass fibre, i-carbon fibre kanye ne-Kevlar® (i-aramid fiber). I-Glass fiber ivamise ukuba yintandokazi emhlabeni wonke, kuyilapho i-carbon fibre inikeza ukuqina okuphezulu kanye ne-Kevlar® ukumelana nokuhuzuka okuphezulu. Khumbula ukuthi izinhlobo zendwangu zingahlanganiswa kuma-laminates ukuze zenze izitaki ezihlanganisiwe ezinikeza izinzuzo zezinto ezingaphezu kweyodwa.
I-Fiberglass Reinforcements
I-Fiberglass yinto eyaziwayo. I-Fiberglass iyisisekelo semboni yezinhlanganisela. Isetshenziswe ezinhlelweni eziningi eziyinhlanganisela kusukela ngawo-1950 futhi izakhiwo zayo ezibonakalayo ziqondwa kahle. I-Fiberglass ayisindi, inamandla amaphakathi namandla acindezelayo, ingamelana nomonakalo nokulayisha ngomjikelezo, futhi kulula ukuyiphatha. Imikhiqizo evela ekukhiqizweni yaziwa njengemikhiqizo ye-fiberglass reinforced plastic (FRP). Kuvamile kuzo zonke izici zokuphila. Isizathu esenza kuthiwe i-fiberglass yingoba lolu hlobo lwefilamenti lwenziwa ngokuncibilikisa i-quartz nezinye izinto zensimbi emazingeni okushisa aphezulu zibe udaka lwengilazi. Bese ekhishwa ngesivinini esikhulu imicu. Lolu hlobo fibre kungenxa ukwakheka ezahlukene have many in. Izinzuzo ukumelana nokushisa, ukumelana nokugqwala, amandla amakhulu. I-insulation enhle. Futhi i-carbon fiber inesimo esifanayo lapho umkhiqizo ubhidlika. I-ductility engalungile. Ayizweli. Njengamanje, ukwahlukanisa, ukugcinwa kokushisa, i-anti-corrosion kulula nezinye izinkambu eziningi zisebenzisa i-glass fiber reinforced plastic.
I-Fiberglass isetshenziswa kakhulu kuzo zonke izinhlanganisela ezitholakalayo. Lokhu kubangelwa kakhulu izindleko zayo eziphansi kanye nezakhiwo zomzimba ezilinganiselayo. I-Fiberglass ifaneleka kahle kumaphrojekthi ansuku zonke nezingxenye ezingadingi indwangu yefiber efunwa kakhulu ukuze iqinise amandla nokuqina.
Ukwandisa izakhiwo zamandla ze-fiberglass, ingasetshenziswa ngama-epoxy resins futhi ingelapheka kusetshenziswa amasu ajwayelekile okuthambisa. Ifaneleka kahle ekusetshenzisweni kwezimboni zezimoto, zasolwandle, ezokwakha, zamakhemikhali nezomkhathi futhi ivame ukusetshenziswa ezimpahleni zemidlalo.

I-Aramid Fiber Reinforcement
I-Aramid fiber iyinhlanganisela yamakhemikhali esezingeni eliphezulu. Inamandla amakhulu, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, isisindo esincane nezinye izici, futhi ingenye yezinto ezibalulekile embonini yezokuvikela. Kunenani elikhulu lezicelo emishinini yokuvikela izinhlamvu, imishini yendiza.
Imicu ye-Aramid ingenye yemicu yokuqala yokwenziwa enamandla aphezulu ukuze yamukelwe embonini ye-fiber-reinforced plastics (FRP). Imicu ye-para-aramid yezinga eliyinhlanganisela ayisindi, inamandla athile aqinile okuqinile, futhi ibhekwa njengokumelana kakhulu nomthelela nokuhuzuka. Izicelo ezijwayelekile zihlanganisa ama-hulls angasindi afana nama-kayak nezikebhe, amaphaneli e-fuselage yendiza nemikhumbi yokucindezela, amagilavu amelana nokusikwa, amavesti angangenwa izinhlamvu nokunye. Imicu ye-Aramid isetshenziswa nge-epoxy noma i-vinyl ester resins.

I-Carbon Fiber Reinforcement
Ngokuqukethwe kwekhabhoni engaphezu kuka-90%, i-carbon fiber inamandla amakhulu kakhulu embonini ye-FRP. Eqinisweni, iphinde ibe namandla amakhulu embonini wokucindezela nokuguquguquka. Ngemuva kokucubungula, le micu iyahlanganiswa ukuze yakhe i-carbon fibre reinforcements njengezindwangu namathowuzi. I-Carbon fiber reinforcement inikeza amandla athile aphezulu kanye nokuqina okuthile, futhi ngokuvamile kubiza kakhulu kunezinye iziqinisekiso zefayibha.
Ukwandisa izakhiwo zamandla e-carbon fiber, kufanele isetshenziswe nama-epoxy resins futhi ingelapheka kusetshenziswa amasu ajwayelekile alamination. Ilungele ukusetshenziswa kwezimoto, zasolwandle kanye ne-aerospace futhi ivame ukusetshenziswa ezimpahleni zemidlalo.
