Thepa ea 'mele ea metsoako e laoloa ke likhoele. Sena se bolela hore ha li-resin le likhoele li kopanngoa, thepa ea tsona e tšoana haholo le ea likhoele ka bonngoe. Lintlha tsa liteko li bontša hore thepa e matlafalitsoeng ke fiber ke likarolo tse jarang boholo ba moroalo. Ka hona, khetho ea lesela e bohlokoa haholo ha ho raloa meaho e kopaneng.
Qala ts'ebetso ka ho fumana mofuta oa matlafatso o hlokahalang bakeng sa projeke ea hau. Moetsi ea tloaelehileng a ka khetha ho tsoa mefuteng e meraro e tloaelehileng ea matlafatso: fiber ea khalase, fiber ea carbon le Kevlar® (fiber ea aramid). Faeba ea khalase e atisa ho ba khetho e akaretsang, ha fiber ea carbon e fana ka ho tiea ho hoholo le ho hanyetsa ho hoholo ha Kevlar®. Hopola hore mefuta ea lesela e ka kopanngoa ka har'a laminate ho etsa li-stack tse kopantsoeng tse fanang ka melemo ea thepa e fetang e le 'ngoe.
Matlafatso a Fiberglass
Fiberglass ke thepa e tsebahalang. Fiberglass ke motheo oa indasteri ea metsoako. E sebelisitsoe lits'ebetsong tse ngata tsa metsoako ho tloha ka bo-1950 'me thepa ea eona ea' mele e utloisisoa hantle. Fiberglass e bobebe, e na le matla a ho tsitlella le a ho hatella a itekanetseng, e ka mamella tšenyo le mojaro oa potoloho, 'me e bonolo ho e sebetsana. Lihlahisoa tse hlahang tlhahisong li tsejoa e le lihlahisoa tsa polasetiki e matlafalitsoeng ea fiberglass (FRP). E tloaelehile likarolong tsohle tsa bophelo. Lebaka leo e bitsoang fiberglass ka lona ke hobane mofuta ona oa fiberglass o etsoa ka ho qhibilihisa quartz le lisebelisoa tse ling tsa ore mochesong o phahameng ho ba slurry ea khalase. Ebe e huloa ka li-filament tse lebelo le phahameng. Mofuta ona oa fiber o bakoa ke motsoako oa tse fapaneng tse nang le tse ngata. Melemo ke ho hanyetsa mocheso, ho hanyetsa ho bola, matla a maholo. Ho thibela ho bola ho hoholo. 'Me fiber ea carbon e na le bothata bo tšoanang ke hore sehlahisoa se tetebela haholoanyane. Ho fokola ha ductility. Ha e na ho tsofala. Hona joale, ho thibela ho bola ho bonolo, ho boloka mocheso, ho thibela ho bola ho bonolo le masimo a mang a mangata a na le tšebeliso ea polasetiki e matlafalitsoeng ea fiberglass.
Fiberglass ke eona e sebelisoang haholo har'a metsoako eohle e fumanehang. Sena se bakoa haholo ke litšenyehelo tsa eona tse tlase le thepa ea eona ea 'mele e itekanetseng. Fiberglass e loketse merero ea letsatsi le letsatsi le likarolo tse sa hlokeng lesela la faeba le hlokang matla a mangata bakeng sa matla le ho tšoarella ho eketsehileng.
Ho eketsa matla a fiberglass, e ka sebelisoa ka li-resin tsa epoxy 'me e ka phekoloa ho sebelisoa mekhoa e tloaelehileng ea lamination. E loketse hantle bakeng sa ts'ebeliso indastering ea likoloi, ea likepe, ea kaho, ea lik'hemik'hale le ea lifofane 'me e sebelisoa hangata linthong tsa lipapali.

Matlafatso ea Aramid Fiber
Faeba ea Aramid ke motsoako oa lik'hemik'hale oa theknoloji e phahameng. E na le matla a phahameng, ho hanyetsa mocheso o phahameng, ho hanyetsa mafome, boima bo bobebe le litšobotsi tse ling, 'me ke e' ngoe ea lisebelisoa tsa bohlokoa indastering ea tšireletso. Ho na le palo e kholo ea lits'ebetso lisebelisoa tse thibelang likulo, lisebelisoa tsa ho fofa.
Lifaeba tsa Aramid ke e 'ngoe ea lifaeba tsa pele tsa maiketsetso tse matla haholo tse amoheloang indastering ea polasetiki e matlafalitsoeng ke faeba (FRP). Lifaeba tsa para-aramid tsa sehlopha sa Composite li bobebe, li na le matla a ikhethang a ho thapolla, 'me li nkoa li hanela haholo tšusumetso le ho khohlana. Litšebeliso tse tloaelehileng li kenyelletsa li-hull tse bobebe tse kang kayaks le liketsoana, liphanele tsa fuselage tsa lifofane le lijana tsa khatello, liatlana tse sa sehiloeng, li-vest tse sa keneleng likulo le tse ling. Lifaeba tsa Aramid li sebelisoa ka li-resin tsa epoxy kapa vinyl ester.

Matlafatso ea Faeba ea Khabone
Ka lebaka la khabone e fetang 90%, faeba ya khabone e na le matla a ho thaepa a hodimo ka ho fetisisa indastering ya FRP. Ha e le hantle, e boetse e na le matla a maholo ka ho fetisisa a ho hatella le ho tenyetseha indastering. Kamora ho sebetswa, difaeba tsena di kopanngwa ho etsa matlafatso a faeba ya khabone jwalo ka masela le dithapo. Matlafatso ya faeba ya khabone e fana ka matla a ikgethang a hodimo le ho tiya ho ikgethang, mme hangata e bitsa tjhelete e ngata ho feta matlafatso a mang a faeba.
Ho eketsa matla a faeba ya khabone, e lokela ho sebediswa le di-resin tsa epoxy mme e ka phekolwa ho sebediswa mekgwa e tloaelehileng ya ho lamination. E loketse hantle bakeng sa ditshebediso tsa dikoloi, tsa lewatle le tsa difofane mme hangata e sebediswa dipapading.
