Zinthu zakuthupi za kompositi zimayendetsedwa ndi ulusi. Izi zikutanthauza kuti pamene utomoni ndi ulusi zimagwirizanitsidwa, katundu wawo ndi ofanana kwambiri ndi wa ulusi wa munthu. Deta yoyesa ikuwonetsa kuti zida zolimbitsa ulusi ndizomwe zimanyamula katundu wambiri. Choncho, kusankha nsalu n'kofunika kwambiri popanga mapangidwe amagulu.
Yambitsani ndondomekoyi pozindikira mtundu wa kulimbikitsa kofunikira pa polojekiti yanu. Wopanga wamba amatha kusankha kuchokera kumitundu itatu yodziwika bwino yolimbikitsira: ulusi wagalasi, kaboni fiber ndi Kevlar® (aramid fiber). Ulusi wagalasi umakonda kukhala chisankho chapadziko lonse lapansi, pomwe kaboni fiber imapereka kuuma kwakukulu komanso kukana kwa Kevlar® kutsekemera kwambiri. Kumbukirani kuti mitundu ya nsalu imatha kuphatikizidwa mu laminates kuti apange masiketi osakanizidwa omwe amapereka phindu lazinthu zambiri.
Fiberglass Reinforcements
Fiberglass ndi chinthu chodziwika bwino. Fiberglass ndiye maziko amakampani opanga zinthu. Lakhala likugwiritsidwa ntchito pazinthu zambiri zophatikizika kuyambira m'ma 1950s ndipo mawonekedwe ake amamveka bwino. Fiberglass ndi yopepuka, imakhala ndi mphamvu zolimbitsa thupi komanso zopondereza, imatha kupirira kuwonongeka ndi kukweza kwapang'onopang'ono, ndipo ndiyosavuta kuigwira. Zogulitsa zomwe zimachokera pakupanga zimadziwika kuti fiberglass reinforced plastic (FRP). Ndilofala m’mbali zonse za moyo. Chifukwa chomwe chimatchedwa fiberglass ndi chifukwa chamtundu uwu wa ulusi wopangidwa ndi kusungunula quartz ndi zinthu zina za ore pa kutentha kwakukulu kukhala slurry wagalasi. Ndiyeno anatulutsa pa liwilo filaments. Mtundu uwu wa CHIKWANGWANI ndi chifukwa zikuchokera zosiyanasiyana ali ambiri. Ubwino ndi kutentha kukana, dzimbiri kukana, mphamvu yaikulu. Insulation yabwino. Ndipo mpweya CHIKWANGWANI ali kuipa chimodzimodzi ndi mankhwala kwambiri Chimaona. Kusayenda bwino. Osamva kuvala. Pakali pano, kutchinjiriza, kuteteza kutentha, anti-corrosion mosavuta ndi madera ena ambiri amagwiritsa ntchito pulasitiki yolimbitsa magalasi.
Fiberglass ndiyomwe imagwiritsidwa ntchito kwambiri pamitundu yonse yomwe ilipo. Izi zimachitika makamaka chifukwa cha mtengo wake wotsika komanso mawonekedwe ake akuthupi. Fiberglass ndi yoyenera pama projekiti atsiku ndi tsiku komanso magawo omwe safuna kwambiri nsalu ya ulusi kuti ikhale yolimba komanso yolimba.
Kuti muwonjezere mphamvu ya fiberglass, itha kugwiritsidwa ntchito ndi epoxy resins ndipo imatha kuchiritsidwa pogwiritsa ntchito njira zoyezera. Ndiwoyenera kugwiritsidwa ntchito m'mafakitale amagalimoto, am'madzi, omanga, opangira mankhwala komanso oyendetsa ndege ndipo amagwiritsidwa ntchito kwambiri pazamasewera.

Aramid Fiber Reinforcement
Aramid fiber ndi mankhwala apamwamba kwambiri. Lili ndi mphamvu zambiri, kukana kutentha kwakukulu, kukana kwa dzimbiri, kulemera kwa thupi ndi zina, ndipo ndi chimodzi mwa zinthu zofunika kwambiri pachitetezo cha chitetezo. Pali chiwerengero chachikulu cha ntchito mu zipangizo bulletproof, zipangizo ndege.
Ulusi wa Aramid ndi imodzi mwazinthu zoyamba zopanga mphamvu zapamwamba kuti zivomerezedwe mumakampani opanga mapulasitiki (FRP). Ulusi wophatikizika wa para-aramid ndi wopepuka, uli ndi mphamvu zapadera zokhazikika, ndipo amawonedwa kuti ndi wosamva kukhudzidwa ndi kuyabwa. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo zikopa zopepuka monga kayak ndi mabwato, mapanelo a fuselage oyendetsa ndege ndi zotengera zokakamiza, magolovesi osamva, ma vests oteteza zipolopolo ndi zina zambiri. Ulusi wa Aramid umagwiritsidwa ntchito ndi epoxy kapena vinyl ester resins.

Carbon Fiber Reinforcement
Ndi kaboni wopitilira 90%, mpweya wa kaboni umakhala wamphamvu kwambiri pamakampani a FRP. M'malo mwake, ilinso ndi mphamvu zopondereza komanso zosinthika kwambiri pamsika. Pambuyo pokonza, ulusiwu umaphatikizidwa kuti upangire zowonjezera zowonjezera kaboni monga nsalu ndi zokoka. Carbon fiber reinforcement imapereka mphamvu zenizeni komanso kuuma kwina, ndipo nthawi zambiri imakhala yokwera mtengo kuposa zowonjezera zina.
Kuti muwonjezere mphamvu ya carbon fiber, iyenera kugwiritsidwa ntchito ndi epoxy resins ndipo ikhoza kuchiritsidwa pogwiritsa ntchito njira zokhazikika. Ndizoyenera kugwiritsa ntchito magalimoto, zam'madzi komanso zam'mlengalenga ndipo nthawi zambiri zimagwiritsidwa ntchito pazinthu zamasewera.
