Galasi la Fiberglassndi chinthu chopangidwa ndi ulusi chopangidwa ndi galasi chomwe gawo lake lalikulu ndi silicate. Chimapangidwa kuchokera ku zinthu zopangira monga mchenga wa quartz woyeretsedwa kwambiri ndi miyala yamchere kudzera mu njira yosungunula, kupyapyala ndi kutambasula kutentha kwambiri. Ulusi wagalasi uli ndi mphamvu zabwino kwambiri zakuthupi ndi zamakemikolo ndipo umagwiritsidwa ntchito kwambiri muzomangamanga, ndege, magalimoto, zamagetsi, ndi mphamvu zamagetsi.
Gawo lalikulu la ulusi wagalasi ndi silicate, momwe zinthu zazikulu ndi silicate ndi okosijeni. Silicate ndi chinthu chopangidwa ndi ma ayoni a silicate ndi ma ayoni a okosijeni okhala ndi formula ya mankhwala ya SiO2. Silicate ndi chimodzi mwa zinthu zambiri zomwe zili mu nthaka ya dziko lapansi, pomwe okosijeni ndiye chinthu chochuluka kwambiri mu nthaka ya dziko lapansi. Chifukwa chake, ma silicate, gawo lalikulu la ulusi wagalasi, ndi ofala kwambiri Padziko Lapansi.

Kukonzekera ulusi wagalasi kumafuna kugwiritsa ntchito zinthu zopangira zoyera kwambiri, monga mchenga wa quartz. Zinthu zopangirazi zimakhala ndi silicon dioxide yambiri (Si02). Panthawi yokonzekera, zinthu zopangirazi zimasungunuka kaye kukhala madzi ngati galasi. Kenako, madzi ngati galasi amatambasulidwa kukhala ulusi pogwiritsa ntchito njira ya fibrillation. Pomaliza, galasi lopangidwa ndi ulusi limaziziritsidwa ndikukonzedwa kuti lipange ulusi wagalasi.
Ulusi wagalasiIli ndi zinthu zambiri zabwino kwambiri. Choyamba, ili ndi mphamvu zambiri komanso kuuma komwe kumatha kupirira mphamvu monga kupsinjika, kupsinjika ndi kupindika. Chachiwiri, ulusi wagalasi uli ndi kachulukidwe kochepa komwe kumapangitsa kuti chinthucho chikhale chopepuka. Kuphatikiza apo, ulusi wagalasi ulinso ndi kukana dzimbiri komanso kukana kutentha kwambiri, ungagwiritsidwe ntchito kwa nthawi yayitali m'malo ovuta. Kuphatikiza apo, ulusi wagalasi ulinso ndi zinthu zabwino kwambiri zotetezera magetsi komanso zinthu zabwino zoyatsira mawu, ndipo umagwiritsidwa ntchito kwambiri m'munda wazamagetsi ndi mawu.
