Iimpawu ezibonakalayo zezinto ezidityanisiweyo zilawulwa yimicu. Oku kuthetha ukuba xa i-resin kunye nemicu zidibene, 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. Abavelisi abaqhelekileyo banokukhetha kwizinto ezintathu eziqhelekileyo zokuqinisa: ifayibha yeglasi, ifayibha yekhabhoni kunye neKevlar® (ifayibha ye-aramid). Iifayibha zeglasi zihlala ziyindlela eqhelekileyo yokukhetha, ngelixa iifayibha zekhabhoni zinika ukuqina okuphezulu kunye nokumelana nokukrala okuphezulu kweKevlar®. Khumbula ukuba iintlobo zelaphu zinokudityaniswa kwiilaminate ukwenza ii-hybrid stacks kunye neenzuzo zezinto ezingaphezu kwesinye.

Wakuba ugqibile ngengqokelela yelaphu, khetha ubunzima kunye nesitayile sokuluka esifanela iimfuno zomsebenzi wakho. Okukhona ilaphu lilula kakhulu, kokukhona kulula ukulifaka phezu kwemiphezulu eneekhonteyine ezininzi. Ikhaphukhaphu ikwasebenzisa i-resin encinci, ngoko ke i-laminate iyonke isalula. Njengoko amalaphu esiba nzima, aya eguquguquka kancinci. Ubunzima obuphakathi bugcina ukuguquguquka okwaneleyo ukugubungela uninzi lweekhonteyine, kwaye zinegalelo elikhulu kumandla enxalenye. Ziyabiza kakhulu kwaye zivelisa izinto ezinamandla nezikhaphukhaphu kwiimoto, zaselwandle nakwimizi-mveliso. Ii-braided rovings zizinto eziqinileyo ezisetyenziswa kakhulu ekwakheni iinqanawa nasekwenzeni isikhunta.

Indlela ilaphu elukiweyo ngayo ithathwa njengephethini okanye isitayile salo. Khetha kwiindlela ezintathu eziqhelekileyo zokuluka: ezicacileyo, ezi-satin kunye ne-twill. Iindlela zokuluka ezicacileyo zezona zingabizi kakhulu kwaye aziguquguquki kangako, kodwa zibamba kakuhle xa zisikiwe. Ukudityaniswa rhoqo kwemisonto phezulu/ezantsi kunciphisa amandla okuluka okucacileyo, nangona kusanele kuzo zonke izicelo ngaphandle kweyona iphezulu yokusebenza.

I-Satin kunye ne-twill weave zithambile kwaye zomelele kune-plain weave. Kwi-satin weave, intambo enye ye-weft idada phezu kweminye imisonto emithathu ukuya kwesixhenxe ye-warp ize ithungwe phantsi kwenye. Kolu hlobo lwe-loose weave, intambo isebenza ixesha elide, igcina amandla e-theory ye-fiber. I-twill weave inika ulungelelwaniso phakathi kwe-satin kunye ne-plain styles, kunye ne-herringbone effect enqwenelekayo.

Icebiso lobuchwephesha: Ukuze ulungise ilaphu, linqumle kwi-roll nge-engile ye-45-degree. Xa linqumle ngale ndlela, kwanezona laphu zirhabaxa zigquma ngcono ngaphezu kwe-silhouette.

Uqinisekiso lweFiberglass

I-Fiberglass sisiseko soshishino lwe-composites. Isetyenziswe kwiindawo ezininzi zokusebenza kwe-composites ukususela ngeminyaka yoo-1950 kwaye iipropati zayo zomzimba ziqondwa kakuhle. I-Fiberglass ilula, inamandla okuxinana aphakathi kunye nokucinezelwa, inokumelana nomonakalo kunye nemithwalo ejikelezayo, kwaye kulula ukuyiphatha.

I-Fiberglass yeyona isetyenziswa kakhulu kuzo zonke izinto ezidityanisiweyo ezikhoyo. Oku kungenxa yexabiso layo eliphantsi kunye neempawu zayo zomzimba eziphakathi. I-Fiberglass ilungele imisebenzi yemihla ngemihla kunye neendawo ezingadingi mpahla eninzi yokuqinisa nokuqina.

Ukuze i-fiberglass ibe namandla kakhulu, ingasetyenziswa nge-epoxy kwaye inokulungiswa kusetyenziswa iindlela eziqhelekileyo zokulamina. Ilungele ukusetyenziswa kwimizi-mveliso yeemoto, eyolwandle, yokwakha, yeekhemikhali kunye neyeenqwelo moya, kwaye idla ngokusetyenziswa kwimpahla yezemidlalo.

Uqinisekiso lweKevlar®

I-Kevlar® yayiyenye yeefayibha zokuqala zokwenziwa ezinamandla aphezulu ezamkelweyo kushishino lweplastiki eziqiniswe ngefayibha (i-FRP). I-Kevlar® yodidi oludibeneyo ilula, inamandla okutsalwa akhethekileyo, kwaye ithathwa njengengagungqiyo kwaye ayikhubeki. Izicelo eziqhelekileyo ziquka ii-hulls ezikhanyayo ezifana nee-kayaks kunye nee-canoes, iiphaneli ze-fuselage zeenqwelo-moya kunye neenqanawa zoxinzelelo, iiglavu ezinqanyulwayo, izixhobo zomzimba, nokunye. I-Kevlar® isetyenziswa kunye nee-resin ze-epoxy okanye ze-vinyl ester.

Ukuqinisa iCarbon Fiber

Ifayibha yekhabhoni iqulethe ngaphezulu kwe-90% yekhabhoni kwaye inamandla aphezulu okutsalwa kwishishini le-FRP. Enyanisweni, ikwanawo amandla aphezulu okuxinzelela kunye nokugoba kwishishini. Emva kokucubungula, ezi fayibha ziyadibana zenze izinto zokuqinisa ifayibha yekhabhoni ezifana namalaphu, iitowu, kunye nokunye. Ukuqinisa ifayibha yekhabhoni kunika amandla aphezulu kunye nokuqina, kwaye ngokubanzi ibiza kakhulu kunezinye izinto zokuqinisa ifayibha.

Ukuze i-carbon fiber ibe namandla kakhulu, kufuneka isetyenziswe ne-epoxy kwaye inganyangwa kusetyenziswa iindlela eziqhelekileyo zokugquma. Ilungele ukusetyenziswa kwiimoto, elwandle nakwi-aerospace, kwaye isetyenziswa rhoqo kwimpahla yezemidlalo.
