Fiberglass roving yog ib txoj hlua fiberglass uas muaj zog thiab ntau yam hauv kev tsim khoom sib xyaw. Nws siv dav hauv ntau yam kev siv vim nws lub zog tensile siab, qhov ceev tsawg, thiab tshuaj lom neeg zoo heev. Ib qho ntawm cov ntawv thov tseem ceeb ntawm fiberglass roving yog nyob rau hauv kev tsim cov Sheet Molding Compound (SMC). Hauv cov txheej txheem tsim khoom SMC, fiberglass roving yog pub rau hauv lub tshuab txiav rotary, qhov twg nws raug txiav rau hauv qhov luv luv (feem ntau 25mm lossis 50mm) thiab tso rau ntawm cov tshuaj nplaum. Qhov kev sib xyaw ua ke ntawm cov tshuaj nplaum thiab chopped roving no ces compacted rau hauv daim ntawv, tsim cov khoom siv uas zoo heev rau kev sib sau ua ke.
Ntxiv rau SMC, fiberglass roving kuj tseem siv rau hauv cov txheej txheem txau. Ntawm no, qhov roving yog dhau los ntawm rab phom txau, qhov twg nws yog chopped thiab sib xyaw nrog resin ua ntej raug txau rau ntawm pwm. Cov txheej txheem no yog qhov tshwj xeeb tshaj yog rau kev tsim cov duab nyuaj thiab cov qauv loj, xws li lub nkoj hulls thiab cov khoom siv tsheb. Qhov xwm txheej tas mus li ntawm kev roving ua kom ntseeg tau tias cov khoom kawg muaj lub zog siab thiab ruaj khov.
Fiberglass roving kuj zoo tagnrho rau kev siv tes, qhov twg nws tuaj yeem raug woven rau hauv cov ntaub lossis siv ua kev txhawb nqa hauv cov laminates tuab. Nws lub peev xwm los nqus cov resin sai sai (ntub tawm) ua rau nws haum rau cov txheej txheem tes, qhov twg ceev thiab yooj yim ntawm kev tuav yog qhov tseem ceeb. Zuag qhia tag nrho, fiberglass roving yog cov khoom siv ntau yam uas muab lub zog zoo dua thiab kev ua tau zoo hauv ntau yam kev tsim khoom sib xyaw.
