Makhalidwe enieni a zinthu zopangidwa ndi ulusi amalamulidwa ndi ulusi. Izi zikutanthauza kuti utomoni ndi ulusi zikaphatikizidwa, makhalidwe awo amafanana kwambiri ndi a ulusi uliwonse. Deta yoyesera ikuwonetsa kuti zinthu zopangidwa ndi ulusi ndi zomwe zimanyamula katundu wambiri. Chifukwa chake, kusankha nsalu ndikofunikira kwambiri popanga nyumba zopangidwa ndi ulusi.

Yambani njirayi posankha mtundu wa zolimbitsa zomwe zimafunika pa ntchito yanu. Opanga nthawi zambiri amatha kusankha kuchokera ku zinthu zitatu zolimbitsa zomwe zimagwiritsidwa ntchito: ulusi wagalasi, ulusi wa kaboni ndi ulusi wa Kevlar® (uramide). Ulusi wagalasi nthawi zambiri umakhala chisankho cha ntchito zambiri, pomwe ulusi wa kaboni umapereka kuuma kwambiri komanso kukana kukwawa kwambiri kwa Kevlar®. Kumbukirani kuti mitundu ya nsalu imatha kuphatikizidwa mu ma laminate kuti apange ma hybrid stacks okhala ndi maubwino a zinthu zingapo.

Mukasankha zosonkhanitsira nsalu, sankhani kulemera ndi kalembedwe kolukidwa komwe kukugwirizana ndi zosowa za ntchito yanu. Nsalu ikapepuka kwambiri, zimakhala zosavuta kuyika pamwamba pa zinthu zozungulira kwambiri. Zopepuka zimagwiritsanso ntchito utomoni wochepa, kotero laminate yonse imakhalabe yopepuka. Nsalu zikamalemera, zimakhala zosasinthasintha. Kulemera kwapakati kumakhalabe kosinthasintha kokwanira kuti iphimbe mizere yambiri, ndipo zimathandiza kwambiri kulimba kwa gawolo. Ndi zotsika mtengo kwambiri ndipo zimapanga zinthu zolimba komanso zopepuka zogwirira ntchito zamagalimoto, zapamadzi ndi zamafakitale. Ma roving oluka ndi zinthu zolemera zomwe zimagwiritsidwa ntchito kwambiri popanga zombo ndi kupanga nkhungu.

Mmene nsalu imalukidwira imaonedwa ngati kapangidwe kake kapena kalembedwe kake. Sankhani kuchokera ku mitundu itatu yodziwika bwino yoluka: yosavuta, satin ndi twill. Mitundu yoluka yosavuta ndiyo yotsika mtengo komanso yosasinthasintha, koma imagwirana bwino ikadulidwa. Kuphatikiza ulusi pafupipafupi kumachepetsa mphamvu ya nsalu yoluka yosavuta, ngakhale kuti imakhala yokwanira kugwiritsa ntchito zinthu zonse kupatula ntchito zapamwamba kwambiri.

Ulusi wa Satin ndi twill ndi wofewa komanso wolimba kuposa ulusi wamba. Mu ulusi wa satin, ulusi umodzi wa weft umayandama pa ulusi wina wopindika katatu mpaka kasanu ndi kawiri kenako umasokedwa pansi pa ulusi wina. Mu mtundu uwu wopindika wosasunthika, ulusi umayenda nthawi yayitali, kusunga mphamvu ya ulusi. Ulusi wa twill umapereka mgwirizano pakati pa ulusi ndi mitundu yopindika, ndi zotsatira zabwino kwambiri zokongoletsera za herringbone.

Malangizo aukadaulo: Kuti nsalu ikhale yofewa, iduleni kuchokera pa mpukutu pa ngodya ya madigiri 45. Mukadula motere, ngakhale nsalu zofewa kwambiri zimaoneka bwino pamwamba pa silhouette.

Kulimbitsa Magalasi a Fiberglass

Fiberglass ndiye maziko a makampani opanga zinthu zosiyanasiyana. Yakhala ikugwiritsidwa ntchito m'mafakitale ambiri kuyambira m'ma 1950 ndipo mawonekedwe ake enieni amamveka bwino. Fiberglass ndi yopepuka, ili ndi mphamvu yolimba komanso yolimba, imatha kupirira kuwonongeka ndi katundu wozungulira, ndipo ndi yosavuta kugwiritsa ntchito.

Fiberglass ndi yomwe imagwiritsidwa ntchito kwambiri pa zinthu zonse zomwe zilipo. Izi zimachitika makamaka chifukwa cha mtengo wake wotsika komanso mawonekedwe ake apakati. Fiberglass ndi yabwino kwambiri pa ntchito za tsiku ndi tsiku komanso pazinthu zomwe sizifuna mphamvu yowonjezera komanso kulimba kwa nsalu ya ulusi.

Kuti fiberglass ikhale ndi mphamvu zambiri, ingagwiritsidwe ntchito ndi epoxy ndipo imatha kuchiritsidwa pogwiritsa ntchito njira zodziwika bwino zoyeretsera. Ndi yabwino kwambiri kugwiritsidwa ntchito m'mafakitale a magalimoto, a m'madzi, omanga, a mankhwala ndi a ndege, ndipo nthawi zambiri imagwiritsidwa ntchito pazinthu zamasewera.

Kulimbitsa Kevlar®

Kevlar® inali imodzi mwa ulusi woyamba wopangidwa ndi mphamvu zambiri womwe unalandiridwa mumakampani opanga mapulasitiki olimbikitsidwa ndi ulusi (FRP). Kevlar® yopangidwa ndi zinthu zosiyanasiyana ndi yopepuka, ili ndi mphamvu yabwino kwambiri yokoka, ndipo imaonedwa kuti ndi yolimba kwambiri komanso yolimba. Ntchito zambiri zimaphatikizapo ma shells owala monga kayaks ndi mabwato, ma fuselage panels a ndege ndi zotengera zopanikizika, magolovesi osadulidwa, zoteteza thupi, ndi zina zambiri. Kevlar® imagwiritsidwa ntchito ndi ma epoxy kapena vinyl ester resins.

Kulimbitsa Ulusi wa Kaboni

Ulusi wa kaboni uli ndi kaboni woposa 90% ndipo uli ndi mphamvu yayikulu kwambiri yogwira ntchito mumakampani a FRP. Ndipotu, ulinso ndi mphamvu yokakamiza komanso yosinthasintha kwambiri mumakampani. Pambuyo pokonza, ulusi uwu umasakanikirana kuti upange zolimbitsa ulusi wa kaboni monga nsalu, zokokera, ndi zina zambiri. Kulimbitsa ulusi wa kaboni kumapereka mphamvu komanso kuuma kwapadera, ndipo nthawi zambiri kumakhala kokwera mtengo kuposa zolimbitsa ulusi zina.

Kuti ulusi wa kaboni ukhale wamphamvu kwambiri, uyenera kugwiritsidwa ntchito ndi epoxy ndipo ukhoza kuchiritsidwa pogwiritsa ntchito njira zodziwika bwino zoyeretsera. Ndi wabwino kwambiri pogwiritsidwa ntchito m'magalimoto, m'madzi ndi m'mlengalenga, ndipo nthawi zambiri umagwiritsidwa ntchito m'zovala zamasewera.
