Ho na le mefuta e 'meli ea li-resin tse sebelisetsoang ho hlahisa metsoako: thermoset le thermoplastic.Li-resin tsa thermoset ke tsona tse atileng haholo, empa li-resin tsa thermoplastic li fumana thahasello e nchafalitsoeng ka lebaka la ts'ebeliso e ntseng e hola ea li-composites.
Li-resin tsa Thermoset li thatafala ka lebaka la ts'ebetso ea ho folisa, e sebelisang mocheso ho theha li-polymers tse hokahaneng haholo tse nang le li-bond tse thata tse sa keneng kapa tse sa qhibiliheng ha li futhumatsoa.Ka lehlakoreng le leng, li-resin tsa thermoplastic ke makala kapa liketane tsa li-monomers tse nolofatsang ha li futhumatsoa 'me li tiea hang ha li pholile, e leng mokhoa o ka khutlisoang o sa hlokeng khokahano ea lik'hemik'hale.Ka bokhuts'oane, o ka khutlisa le ho fetola li-resin tsa thermoplastic, empa eseng li-resin tsa thermoset.

Thahasello ho li-composites tsa thermoplastic ea hola, haholo indastering ea likoloi.

Melemo ea Thermosetting Resins
Li-resin tsa thermoset tse kang epoxy kapa polyester li ratoa tlhahisong e kopaneng ka lebaka la viscosity ea tsona e tlase le ho kenella ho hotle ho marang-rang a fiber.Ka hona hoa khoneha ho sebelisa likhoele tse ngata le ho eketsa matla a thepa e entsoeng e phethiloeng.

Moloko oa morao-rao oa lifofane ka tloaelo o kenyelletsa likarolo tse fetang 50 lekholong tse nang le motsoako.

Nakong ea pultrusion, likhoele li kenngoa ka har'a resin ea thermoset ebe li kenngoa ka har'a hlobo e futhumetseng.Opereishene ena e kenya tšebetsong mokhoa oa ho folisa o fetolang resin ea boima bo tlase ba limolek'hule hore e be sebopeho se tiileng sa marang-rang se nang le mahlakore a mararo moo likhoele li notletsoeng ka har'a marang-rang ana a sa tsoa thehoa.Kaha karabelo e ngata ea pheko ke exothermic, karabelo ena e tsoela pele joalo ka liketane, e nolofalletsang tlhahiso e kholo.Hang ha resin e behiloe, sebopeho sa mahlakore a mararo se notlela likhoele sebakeng sa tsona 'me se fana ka matla le ho satalla ho motsoako.
