Girazi reFiberglasschinhu chine fibrous chakagadzirwa negirazi chine chinhu chikuru chiri silicate. Chakagadzirwa nezvinhu zvakaita sejecha re quartz rakachena zvakanyanya uye limestone kuburikidza nekunyunguduka, fibrillation uye kutambanudza kupisa kwakanyanya. Fiber yegirazi ine hunhu hwakanaka hwemuviri uye hwemakemikari uye inoshandiswa zvakanyanya mukuvaka, zvemuchadenga, zvemotokari, zvemagetsi, uye zvemagetsi.
Chinhu chikuru chegirazi fiber i silicate, umo zvinhu zvikuru zviri silicon ne oxygen. Silicate imusanganiswa unoumbwa nema silicon ions nema oxygen ions ane fomura yemakemikari SiO2. Silicon ndeimwe yezvinhu zvakawanda mu crust yevhu, nepo oxygen iri iyo yakawanda mu crust yevhu. Nokudaro, silicates, iyo inonyanya kukosha mu glass fibers, inowanikwa zvakanyanya paNyika.

Kugadzira girazi fiber kunotanga kwada kushandiswa kwezvinhu zvakachena zvakanyanya, zvakaita se quartz sand limestone. Zvinhu izvi zvine silicon dioxide yakawanda (Si02). Munguva yekugadzirira, zvinhu izvi zvinotanga zvanyungudutswa kuita mvura yakaita segirazi. Zvadaro, mvura yakaita segirazi inotambanudzwa kuita fibrous nenzira ye fibrillation. Pakupedzisira, girazi rine fibrous rinotonhodzwa uye rinogadziriswa kuti rigadzire girazi fibers.
Faibha yegiraziine hunhu hwakawanda hwakanaka. Chekutanga, ine simba guru uye kuomarara inokwanisa kudzivirira masimba akadai sekumanikidzwa, kudzvanywa uye kukotama. Chechipiri, fiber yegirazi ine density shoma inoita kuti chigadzirwa chive chakareruka. Pamusoro pezvo, fiber yegirazi inewo resistance yakanaka yekuora uye resistance yepamusoro yekupisa, inogona kushandiswa kwenguva yakareba munzvimbo dzakaoma. Pamusoro pezvo, fiber yegirazi inewo hunhu hwakanaka hwekudzivirira magetsi uye hunhu hwakanaka hweacoustic, inoshandiswa zvakanyanya mumunda wezvemagetsi uye maacoustics.
