Moetsi ea tloaelehileng a ka khetha mefuta e meraro e tloaelehileng ea ho matlafatsa: fiber ea khalase, carbon fiber le Kevlar® (aramid fiber). Fiber ea khalase e atisa ho ba khetho ea bokahohle, ha carbon fiber e fana ka ho satalla ho phahameng le Kevlar® high abrasion resistance. Hopola hore mefuta ea masela e ka kopanngoa ka li-laminates ho etsa li-stacks tse nyalisitsoeng tse fanang ka melemo ea thepa e fetang e le 'ngoe.
Fiberglass Reinforcements
Fiberglass ke thepa e tloaelehileng. Fiberglass ke motheo oa indasteri ea li-composite. E 'nile ea sebelisoa lits'ebetsong tse ngata tse kopantsoeng ho tloha lilemong tsa bo-1950' me litšobotsi tsa eona tsa 'mele li utloisisoa hantle. Fiberglass e bobebe, e na le matla a leka-lekaneng le a hatellang, e khona ho mamella tšenyo le cyclic loading, 'me e bonolo ho sebetsana le eona. Lihlahisoa tse hlahang tlhahisong li tsejoa e le lihlahisoa tsa polasetiki tse matlafalitsoeng tsa fiberglass (FRP). E tloaelehile likarolong tsohle tsa bophelo. Lebaka leo ka lona e bitsoang fiberglass ke hobane mofuta ona oa fiber filament o etsoa ka ho qhibiliha quartz le lisebelisoa tse ling tsa ore mocheso o phahameng ho kena ka har'a slurry ea khalase. 'Me joale e ntšoa ka li-filaments tsa lebelo le phahameng. Mofuta ona oa fiber o bakoa ke ho hlophisoa ha mefuta e mengata e fapaneng. Melemo ke ho hanyetsa mocheso, ho hanyetsa kutu, matla a maholo. Insulation e ntle. 'Me fiber ea carbon e na le bothata bo tšoanang ke sehlahisoa se brittle ho feta. Ductility e mpe. Ha e senyehe. Hona joale, ho kenya letsoho, ho boloka mocheso, ho thibela ho bola habonolo le masimo a mang a mangata a na le tšebeliso ea polasetiki e matlafalitsoeng ea khalase.
Fiberglass ke eona e sebelisoang haholo ho feta mefuta eohle e fumanehang. Sena se bakoa haholo ke theko ea eona e batlang e le tlase le thepa ea 'mele e itekanetseng.

Ho eketsa matla a matla a fiberglass, e ka sebelisoa ka li-resin tsa epoxy mme e ka phekoloa ka mekhoa e tloaelehileng ea ho lamination. E loketse hantle bakeng sa likopo tsa indasteri ea likoloi, tsa likepe, tsa kaho, tsa lik'hemik'hale le tsa sefofane 'me hangata e sebelisoa thepa ea lipapali.

Aramid Fiber Reinforcement
Aramid fiber ke k'hemik'hale e phahameng ea theknoloji. E na le matla a phahameng, ho hanyetsa mocheso o phahameng, ho hanyetsa kutu, boima bo bobebe le litšobotsi tse ling, 'me ke e' ngoe ea lisebelisoa tsa bohlokoa indastering ea ts'ireletso.

Likhoele tsa Aramid ke e 'ngoe ea likhoele tsa pele tse matla tse entsoeng ka matla a phahameng ho fumana kamohelo indastering ea polasetiki e matlafalitsoeng ka fiber (FRP). Likhoele tsa para-aramid tsa sehlopha sa composite li bobebe, li na le matla a ikhethang a ho tsitsa, 'me li nkuoa li hanana haholo le ts'usumetso le abrasion. Lisebelisoa tse tloaelehileng li kenyelletsa mekotla e bobebe joalo ka li-kayak le liketsoana, liphanele tsa lifofane tsa fuselage le likepe tsa khatello, liatlana tse sa khoneng ho seha, liaparo tsa likulo le tse ling. Likhoele tsa Aramid li sebelisoa ka li-resin tsa epoxy kapa vinyl ester.

Matlafatso ea Fiber ea Carbon
Ka carbon content e fetang 90%, carbon fiber e na le matla a holimo ka ho fetisisa a ho tsitsisa indastering ea FRP. Ha e le hantle, e boetse e na le matla a maholo ka ho fetisisa a khatello le a feto-fetohang a indasteri. Ka mor'a ho sebetsa, likhoele tsena lia kopanngoa ho etsa li-reinforcements tsa carbon fiber tse kang masela le lithapo. Carbon fiber reinforcement e fana ka matla a khethehileng le ho satalla ho itseng, 'me hangata e theko e boima ho feta likhothaletso tse ling tsa fiber.
Ho eketsa matla a matla a carbon fiber, e lokela ho sebelisoa ka li-epoxy resin 'me e ka phekoloa ka mekhoa e tloaelehileng ea ho lamination. E loketse hantle bakeng sa lisebelisoa tsa likoloi, tsa metsing le tsa sefofane 'me hangata e sebelisoa thepa ea lipapali.
