1. Koob xav

Cov ntaub qhwv koob yog muab faib ua cov ntaub qhwv koob thiab cov ntaub qhwv koob txuas ntxiv. Cov ntaub qhwv koob yog txiav cov ntaub qhwv iav mus rau hauv 50 hli, muab tso rau ntawm lub substrate uas muab tso rau ntawm txoj siv conveyor ua ntej, thiab tom qab ntawd siv rab koob rau kev xuas koob, thiab rab koob yuav tho cov ntaub qhwv rau hauv lub substrate Thiab tus nuv crochet coj qee cov ntaub los ua ib qho qauv peb-seem. Lub substrate siv tuaj yeem yog cov ntaub nyias nyias ntawm cov iav fiber lossis lwm cov fibers, thiab cov ntaub qhwv koob no muaj qhov xav fluffy. Nws cov kev siv tseem ceeb suav nrog cov ntaub ntawv rwb thaiv tsev kub thiab cov ntaub ntawv rwb thaiv tsev suab, cov ntaub ntawv rwb thaiv tsev kub, cov ntaub ntawv lim dej, thiab kuj tuaj yeem siv rau hauv kev tsim khoom ntawm FRP, tab sis lub zog ntawm FRP yog qis thiab qhov ntau thiab tsawg ntawm kev siv yog txwv. Lwm hom ntaub qhwv koob txuas ntxiv yog ib qho ntaub qhwv uas cov ntaub qhwv iav txuas ntxiv raug pov tseg rau ntawm txoj siv txuas ntxiv nrog lub cuab yeej pov hlau, thiab tom qab ntawd koob los ntawm lub phaj koob los ua ib qho qauv peb-seem uas cov ntaub sib txuas. Hom ntaub qhwv no feem ntau yog siv rau hauv kev tsim cov ntaub qhwv iav fiber txhawb nqa thermoplastic stampable.

2. Fiberglass Chopped Strand Mat - Hmoov binder
Cov iav raw filaments tsim thaum lub sijhawm kos duab lossis cov raw filaments txuas ntxiv tawm ntawm lub raj raw filament raug tso rau ntawm txoj siv sia txuas ntxiv mus rau hauv daim duab ntawm 8 thiab raug sib txuas los ntawm cov nplaum hmoov. Cov fiber hauv cov iav fiber txuas ntxiv yog txuas ntxiv mus, yog li nws muaj cov nyhuv txhawb nqa zoo dua rau cov khoom sib xyaw.

3.FiberglassCov ntaub pua plag txiav - Emulsion binder
Txiav cov iav fiber (qee zaum kuj siv cov roving tsis sib ntswg) rau hauv 50 hli ntev, nthuav nws random tab sis sib npaug ntawm txoj siv mesh, thiab tom qab ntawd siv cov nplaum emulsion lossis sprinkle hmoov khi tus neeg sawv cev kom sov thiab khov thiab khi nws rau hauv cov ntaub luv luv txiav raw silk felt. Cov ntaub pua plag txiav feem ntau yog siv rau hauv kev teeb tsa tes, kev ua board txuas ntxiv thiab compression molding thiab SMC cov txheej txheem. Cov kev xav tau zoo rau cov ntaub pua plag txiav yog raws li nram no: ① Qhov zoo ntawm thaj chaw yog sib xws raws li qhov dav; ② Cov xov txiav tau faib sib npaug hauv qhov chaw ntawm daim ntaub pua plag tsis muaj qhov loj, thiab cov binder tau faib sib npaug; ③Muaj lub zog lev qhuav nruab nrab; ④Zoo heev Cov resin infiltration thiab permeability.
