Kukho iintlobo ezimbini zeerasi ezisetyenziselwa ukuvelisa i-composites: i-thermoset kunye ne-thermoplastic.Iiresin ze-Thermoset zezona ziqhelekileyo, kodwa i-thermoplastic resins ifumana umdla ohlaziyiweyo ngenxa yokusetyenziswa okwandisiweyo kwee-composites.
I-Thermoset resins iyaqina ngenxa yenkqubo yokunyanga, esebenzisa ubushushu ukwenza iipolymers ezinqamlezileyo kakhulu ezinamabhondi anganyibilikiyo okanye anganyibilikiyo anganyibiliki xa eshushu.Ngakolunye uhlangothi, iireyini ze-Thermoplastic, ngamasebe okanye amatyathanga e-monomers athambileyo xa eshushu kwaye aqina xa sele epholile, inkqubo ebuyiselwa umva engadingi kudibaniswa kweekhemikhali.Ngamafutshane, unokuphinda uhlaziye kwaye uguqule iireyini ze-thermoplastic, kodwa hayi i-thermoset resins.

Umdla kwiicomposites ze-thermoplastic uyakhula, ngakumbi kushishino lweemoto.

Izinto ezilungileyo ze-Thermosetting Resins
Iiresin ze-Thermoset ezifana ne-epoxy okanye i-polyester zithandwa kwimveliso edibeneyo ngenxa ye-viscosity yazo ephantsi kunye nokungena okugqwesileyo kuthungelwano lwefayibha.Ngaloo ndlela kunokwenzeka ukusebenzisa iifiber ezininzi kunye nokwandisa amandla ezinto ezigqityiweyo ezidibeneyo.

Isizukulwana samva nje seenqwelomoya sidla ngokuquka ngaphezu kwama-50 ekhulwini amacandelo ayintlanganisela.

Ngexesha le-pultrusion, iifibers zifakwe kwi-resin ye-thermoset kwaye zifakwe kwi-mold evuthayo.Lo msebenzi uvula ukusabela okunyangayo okuguqula i-resin ephantsi-molekyuli-ubunzima kwisakhiwo sothungelwano esine-dimensional ezintathu eziqinileyo apho iintsinga zitshixiwe kolu nxibelelwano lutsha.Kuba uninzi lweempendulo zokunyanga ziyingozi, ezi mpendulo ziyaqhubeka njengamatyathanga, zenza imveliso enkulu.Emva kokuba i-resin iseti, isakhiwo se-three-dimensional sivalela iifiber endaweni kwaye sinika amandla kunye nokuqina kwi-composite.
