Izakhiwo ezibonakalayo zezinto ezihlanganisiwe zilawulwa yimicu. Lokhu kusho ukuthi lapho i-resin nemicu ye-resin ihlanganiswe, izakhiwo zawo zifana kakhulu neyemicu ngakunye. Idatha yokuhlola ikhombisa ukuthi izinto eziqinisiwe ze-fiber ziyizakhi ezithwala iningi lomthwalo. Ngakho-ke, ukukhethwa kwendwangu kubalulekile lapho uhlela izinhlaka eziyinhlanganisela.

Qala inqubo ngokunquma uhlobo lokuqiniswa oludingekayo kwiphrojekthi yakho. Abakhiqizi abajwayelekile bangakhetha kusuka ezintweni ezintathu ezigcizelelwa ngokuqinisa: i-fiber ye-glass, i-carbon fiber kanye ne-kevlar® (i-aramid fiber). Imicu yengilazi ithambekele ekukhetheni inhloso ejwayelekile, kanti ama-carbon fibers anikeza ukuqina okuphezulu kanye nokumelana nokuphikiswa okuphezulu kweKevlar®. Khumbula ukuthi izinhlobo zendwangu zingahlanganiswa ngama-laminates ukuze kufakwe izitaki ezi-hybrid ngezinzuzo zezinto ezingaphezu kweyodwa.

Uma usunqume eqoqweni lendwangu, khetha isisindo nesitayela seave esifanelana nezidingo zomsebenzi wakho. I-ounce ekhanyayo yendwangu, kube lula ukudonsa ngezindawo ezibunjiwe kakhulu. I-Lightweight nayo isebenzisa i-resin encane, ngakho-ke i-laminate ephelele iselula. Njengoba izindwangu zisinda, ziguquguquka kancane. Isisindo esiphakathi sigcina ukuguquguquka okwanele ukumboza imigqa eminingi, futhi banikela kakhulu ngamandla engxenye. Zingokomnotho kakhulu futhi zikhiqiza izakhi eziqinile nezingasindi zezicelo zezimoto, zasolwandle kanye nezimboni. Ukuphamba okunamafutha kuqiniswa kakhulu okusetshenziswa kakhulu ekwakhiweni kwemikhumbi nokwenza isikhunta.

Indlela indwangu eyenziwe ngayo ibhekwa njengendlela yayo noma isitayela sayo. Khetha kusuka ezitayeleni ezintathu ezijwayelekile ze-weave: Plain, Satin noTill. Izitayela ezithambile ze-weave zingabashiyeli futhi zivumelana nezimo okuncane, kepha zibambe kahle lapho zisikiwe. I-Croughts evame ukwehlisa imicu inciphisa amandla we-weave ethafeni, yize isanele kubo bonke kodwa izicelo zokusebenza okuphezulu kakhulu.

I-satin ne-trill eleave iyathambile futhi inamandla kune-weave ecacile. Ku-Satin Suashing, intambo eyodwa yeft iyantanta ezinye izintambo zempi ezintathu kuya kweziyisikhombisa ze-warp futhi zithungwa ngaphansi kolunye. Kulolu hlobo lwe-weave we-weave, intambo isebenza isikhathi eside, igcina amandla e-theoretics wefayibha. I-twill weave inikeza ukuyekethisa phakathi kwezitayela ze-satin nezitayela ezicacile, nge-herringlone evame ukunxusa i-herringlone umphumela.

I-Tech Tip: Ukwengeza ukuguquguquka kwendwangu, ukusika kusuka ku-roll ku-angle engu-45-degree. Lapho usika ngale ndlela, ngisho nezindwangu ezicijile zivuka kangcono phezu kwe-silhouette.

Ukuqiniswa kwe-fiberglass

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 namandla acindezelayo, angamelana nokulimala kanye nemithwalo ye-cyclic, futhi kulula ukuyiphatha.

I-fiberglass yiyona esetshenziswa kakhulu kuzo zonke izinto ezi-composite ezikhona. Lokhu kungenxa yezindleko zayo eziphansi kakhulu nezinto ezilinganiselayo zomzimba. I-Fibreglass ilungele amaphrojekthi wansuku zonke nezingxenye ezingadingi indwangu eningi ye-fiber angeze amandla nokuqina.

Ukuze wandise izakhiwo zamandla we-fiberglass, zingasetshenziswa nge-epoxy futhi zingalapheka kusetshenziswa amasu ajwayelekile wokukhanya. Ilungele izinhlelo zokusebenza kwizimboni zezimoto, zasolwandle, zokwakha, izimboni zamakhemikhali kanye nezindiza, futhi ivame ukusetshenziswa ezimpahleni zezemidlalo.

UKevlar® ukuqiniswa

UKevlar ® wayengomunye wabasubathi bokuqala obunamandla obukhulu ukuthola ukwamukelwa embonini (i-FRP) eqinisiwe (FRP). I-Composite grade Kevlar® iyi-Lightweight, inamandla amahle kakhulu ashubile, futhi ibhekwa njengomthelela omkhulu kanye nokumelana nokungahambi kahle kwegciwane. Izicelo ezijwayelekile zifaka phakathi ama-hulls akhanyayo anjenge-kayaks kanye nezikebhe, amaphaneli endiza endiza kanye nemikhumbi yokucindezela, amagilavu ​​avinjelwe, izikhali zomzimba, nokuningi. I-Kevlar® isetshenziswa nge-epoxy noma i-vinyl ester resens.

Ukuqiniswa kwe-carbon fiber

I-Carbon fiber iqukethe ama-carbon angaphezu kwama-90% futhi inamandla amakhulu okugcina embonini embonini ye-FRP. Eqinisweni, futhi inamandla aphezulu kakhulu futhi aguquguqukayo embonini. Ngemuva kokucubungula, le micu iyahlangana ukwakha ukuqiniswa kwe-carbon fiber okufana nezindwangu, izigqoko, nokuningi. Ukuqiniswa kwe-carbon fiber kunikeza amandla aphezulu nokuqina, futhi ngokuvamile kuyabiza kakhulu kunokunye ukuqiniswa kwe-fiber.

Ukuze wandise izakhiwo zamandla ze-carbon fiber, kufanele isetshenziswe nge-epoxy futhi ingalashwa kusetshenziswa amasu ajwayelekile wokukhanyisela. Ilungele izinhlelo zokusebenza nge-automotive, marine ne-aerospace, futhi zivame ukusetshenziswa kwezimpahla zezemidlalo.
