Umzi-mveliso we-fiberglass ufumene ukukhula okumangalisayo kunye nophuhliso kule minyaka imbalwa idlulileyo, iqhutywa kukukhula kwemfuno yezinto ezikhaphukhaphu, ezihlala ixesha elide, kunye nokusebenza okuphezulu kumacandelo ahlukeneyo afana nokwakha, iimoto, i-aerospace, kunye namandla avuselelekayo. I-Fiberglass, ekwaziwa ngokuba yiplastiki eyomelezwe ngeglasi (GRP) okanye iplastiki eyomelezwe ngeglasi (GFRP), yimathiriyeli edityanisiweyo eyenziwe ngemisonto yeglasi entle elukwe elaphu kwaye idityaniswe nentlaka. Esi sixhobo sisebenza ngeendlela ezahlukeneyo sinikezela ngomlinganiselo okhethekileyo wobunzima bobunzima, ukuxhathisa ukubola, kunye neempawu zokugquma kwe-thermal, ziyenza ibe lolona khetho lufanelekileyo kuluhlu olubanzi lwezicelo.
