Iimpawu zomzimba zezinto ezidityanisiweyo zilawulwa yimicu. Oku kuthetha ukuba xa zidityanisiwe iiresini kunye nemicu, iimpawu zazo zifana kakhulu nezo zemicu nganye. Idatha yovavanyo ibonisa ukuba izinto eziqiniswe yifayibha zezona zinto zithwala uninzi lomthwalo. Ke ngoko, ukukhetha ilaphu kubalulekile xa kuyilwa izakhiwo ezidityanisiweyo.
Qala inkqubo ngokumisela uhlobo lokuqinisa olufunekayo kwiprojekthi yakho. Umenzi oqhelekileyo unokukhetha kwiintlobo ezintathu eziqhelekileyo zokuqinisa: ifayibha yeglasi, ifayibha yekhabhoni kunye neKevlar® (ifayibha ye-aramid). Ifayibha yeglasi idla ngokuba lolona khetho luqhelekileyo, ngelixa ifayibha yekhabhoni inika ukuqina okuphezulu kunye nokumelana nokukrala okuphezulu kweKevlar®. Khumbula ukuba iintlobo zelaphu zinokudityaniswa kwi-laminates ukwenza ii-hybrid stacks ezibonelela ngeenzuzo zezinto ezingaphezu kwesinye.
Ukuqinisa iFiberglass
I-Fiberglass yinto eqhelekileyo. I-Fiberglass sisiseko soshishino lwee-composites. Isetyenziswe kwizicelo ezininzi ze-composites ukususela ngeminyaka yoo-1950 kwaye iimpawu zayo zomzimba ziqondwa kakuhle. I-Fiberglass ilula, inamandla okuxinana aphakathi kunye namandla okucinezela, inokumelana nomonakalo kunye nomthwalo ojikelezayo, kwaye kulula ukuyiphatha. Iimveliso ezivela kwimveliso zaziwa njengeemveliso zeplastiki eziqinisiweyo ze-fiberglass (FRP). Ixhaphakile kuzo zonke iindawo zobomi. Isizathu sokuba ibizwa ngokuba yi-fiberglass kukuba olu hlobo lwe-fiber filament lwenziwa ngokunyibilikisa i-quartz kunye nezinye izinto ze-ore kumaqondo obushushu aphezulu zibe yi-slurry yeglasi. Emva koko itsalwa nge-filaments yesantya esiphezulu. Olu hlobo lwe-fiber lubangelwa kukwakheka kwe-multiple in. Iingenelo kukumelana nobushushu, ukumelana nokugqwala, amandla amakhulu. Ubushushu obuhle. Kwaye i-carbon fiber inomonakalo ofanayo kukuba imveliso ibuthathaka ngakumbi. Ukuguquguquka okubi. Ayigugi. Okwangoku, ubushushu, ukugcinwa kobushushu, i-anti-corrosion kulula kwaye eminye imimandla emininzi isebenzisa iplastiki eqinisiweyo ye-glass fiber.
I-Fiberglass yeyona isetyenziswa kakhulu kuzo zonke izinto ezidityanisiweyo ezikhoyo. Oku kungenxa yokuba ixabiso layo liphantsi kwaye ineempawu zomzimba eziphakathi. I-Fiberglass ifanelekile kwiiprojekthi zemihla ngemihla kunye neendawo ezingadingi ngelaphu le-fiber elifuna kakhulu amandla nokuqina okongeziweyo.
Ukuze i-fiberglass ibe namandla ngakumbi, ingasetyenziswa nee-epoxy resins kwaye inokunyangeka kusetyenziswa iindlela eziqhelekileyo zokulamina. Ifanelekile ukusetyenziswa kwimizi-mveliso yeemoto, eyolwandle, yokwakha, yeekhemikhali kunye neyeenqwelo moya kwaye isetyenziswa kakhulu kwimpahla yezemidlalo.

Ukuqinisa i-Aramid Fiber
I-Aramid fiber yikhemikhali esetyenziswa kakhulu kwezobuchwepheshe. Inamandla aphezulu, iyamelana nobushushu obuphezulu, iyamelana nokugqwala, inobunzima obuphantsi kunye nezinye iimpawu, kwaye yenye yezinto ezibalulekileyo kwishishini lokhuselo. Kukho inani elikhulu lezicelo kwizixhobo ezikhusela iimbumbulu, izixhobo zokubhabha.
Iifayibha ze-Aramid zezinye zeefayibha zokuqala zokwenziwa ezinamandla aphezulu ezamkelweyo kushishino lweeplastiki eziqinisiweyo ngefayibha (i-FRP). Iifayibha ze-para-aramid ze-composite grade zilula, zinamandla okutsalwa akhethekileyo, kwaye zithathwa njengezimelana kakhulu nempembelelo kunye nokukrazuka. Izicelo eziqhelekileyo ziquka ii-hulls ezilula ezifana nee-kayaks kunye nee-canoes, iiphaneli ze-fuselage zeenqwelo-moya kunye neenqanawa zoxinzelelo, iiglavu ezinqandayo, iivesti ezikhusela iimbumbulu kunye nokunye. Iifayibha ze-Aramid zisetyenziswa kunye nee-resin ze-epoxy okanye ze-vinyl ester.

Ukuqinisa iCarbon Fiber
Ngomxholo wekhabhoni ongaphezulu kwe-90%, i-carbon fiber inamandla aphezulu okutyhala kushishino lwe-FRP. Enyanisweni, ikwanawo amandla amakhulu okucinezela kunye nokugoba kushishino. Emva kokucubungula, ezi fayibha zidityaniswe ukuze zenze izinto zokuqinisa i-carbon fiber ezifana namalaphu kunye neetowu. Ukuqinisa i-carbon fiber kunika amandla aphezulu kunye nokuqina okuthile, kwaye ngokuqhelekileyo kubiza kakhulu kunezinye izinto zokuqinisa i-fiber.
Ukuze i-carbon fiber ibe namandla kakhulu, kufuneka isetyenziswe kunye ne-epoxy resins kwaye inganyangwa kusetyenziswa iindlela eziqhelekileyo zokugquma. Ifanelekile kakhulu kwiimoto, elwandle nakwizinto zeenqwelo moya kwaye isetyenziswa rhoqo kwimpahla yezemidlalo.
