Ifayibha yeglasi inokumelana nobushushu obuphezulu kunefayibha ephilayo, ukungatshi, ukumelana nomhlwa, ukugquma ubushushu obulungileyo kunye nokugqunyelelwa kwesandi (ingakumbi uboya beglasi), ukomelela okuphezulu kunye nokugquma kombane okulungileyo (okufana ne-alkali yeglasi yefayibha esimahla). Nangona kunjalo, i-brittle kwaye ayinakukwazi ukunxiba. Ifayibha yeglasi isetyenziswa kakhulu njengemathiriyeli yokugquma umbane, imathiriyeli yokucoca kwimizi-mveliso, i-anti-corrosion, ubungqina bokufuma, ukugquma ubushushu, ukugquma isandi kunye nemathiriyeli yokufunxa ukothuka. Isenokusetyenziswa njengento yokomeleza ukwenza iiplastiki ezomeleziweyo okanye irabha eyomeleziweyo, igypsum eyomeleziweyo kunye nesamente eyomeleziweyo. Ukuguquguquka kunokuphuculwa ngokugubungela i-fiber yeglasi kunye nezinto eziphilayo, ezinokuthi zisetyenziswe ukwenza iingubo zokupakisha, isikrini sefestile, isambatho sodonga, isambatho esigubungelayo, isambatho sokukhusela, ukugquma kombane kunye nezixhobo zokugquma isandi.

Iglasi ngokuqhelekileyo ithathwa njengento eqinile kwaye enqabileyo kwaye ayifanelekanga kwizinto zokwakha. Nangona kunjalo, ukuba itsalwa kwisilika, amandla ayo aya kwandiswa kakhulu kwaye inokuthamba. Ke ngoko, inokuthi ekugqibeleni ibe yinto entle kakhulu yolwakhiwo emva kokuba inikwe imilo ngeresin. Amandla efiber yeglasi ayanda ngokuncipha kobubanzi bayo. Njengezinto zokuqinisa, i-fiber yeglasi inezi mpawu zilandelayo. Ezi mpawu zenza ukusetyenziswa kwefiber yeglasi kude kakhulu kunezinye iintlobo zefiber, kwaye isantya sophuhliso singaphambili. Iimpawu zayo zidweliswe ngolu hlobo lulandelayo:

(1) Amandla okuqina aphezulu kunye nobude obuncinci (3%).

(2) I-coefficient ephezulu ye-elastic kunye nokuqina okulungileyo.

(3) Inobude obukhulu ngaphakathi komda weelastiki kunye namandla aphezulu okuqina, ngoko ke ifunxa amandla amakhulu empembelelo.

(4) Yifiber ye-inorganic engatshiyo kunye nokuxhathisa okulungileyo kwimichiza.

(5) Ukufunxa amanzi aphantsi.

(6) Uzinzo olulungileyo lwe-dimensional kunye nokumelana nobushushu.

7

(8) Ukukhanya ngokukhanya.

(9) Ukuphuhliswa kwe-ejenti yonyango lomphezulu kunye nokubambelela kakuhle kwi-resin kugqityiwe.

(10) Ixabiso liphantsi
