Umugozi waciwe na fiberglass ukoreshwa cyane cyane mu gushimangira thermoplastics. Kubera ko umugozi waciwe na fiberglass ufite igipimo cyiza cy'ikiguzi, ukwiriye cyane cyane kuvanga na resin kugira ngo ikoreshwe nk'ibikoresho byo gushimangira imodoka, gari ya moshi n'amato: ukoreshwa mu bikoresho birwanya ubushyuhe bwinshi, impapuro zifata amajwi ku modoka, n'ibyuma bishyushye, n'ibindi. Ibicuruzwa byayo bikoreshwa cyane mu modoka, ubwubatsi, mu ndege zikenera buri munsi, nibindi. Ibikoresho bisanzwe ni ibice by'imodoka, ibikoresho by'ikoranabuhanga n'amashanyarazi, ibikoresho bya mekanike, nibindi.
Umugozi waciwe mu ikirahure urashobora gukoreshwa mu gushimangira polyester idasembuye, resin ya vinyl, resin ya epoxy na resin ya phenolic. Ukoreshwa cyane mu gutunganya no guhinga FRP n'intoki, unakoreshwa mu gukora ibumba, gukora amasahani ahoraho, imodoka n'izindi. Umugozi waciwe mu ikirahure ukoreshwa cyane mu miyoboro ya shimi irwanya ingese, ikibaho cy'urumuri cya FRP, icyitegererezo, umunara wo gukonjesha, igisenge cy'imbere cy'imodoka, ubwato, ibice by'imodoka, insulator, ibikoresho by'isuku, intebe, inyubako n'ibindi bikoresho bya FRP.
