Tare da faffadan aikace-aikacen GFRP grillage a cikin aikin injiniyan farar hula, bincike kan aikinsa da hanyar aikace-aikacensa a cikin injiniyan farar hula ya sami ci gaba. A lokuta daban-daban, akwai buƙatun aiki daban-daban don grille na FRP da aka yi amfani da su. Amma gaba ɗaya, mafi yawan duka, yana buƙatar rayuwa mai tsawo, gabaɗaya shekaru, har ma shekaru da yawa. Hakanan ana buƙatar ingancin kayan don zama mai tauri kuma nauyin kowane yanki yana da nauyi (100-500g/m2 sama). Wasu suna buƙatar mai kyau mai tsaftar ruwa da kiyaye sauti, wasu na buƙatar rashin ruwa. Don haka, wajibi ne a fahimci kaddarorinsa na zahiri, kayan aikin injiniya, da kayan aikin ruwa
1. Kaddarorin jiki
(1) isotropy: ƙarfi, taurin kai da elasticity na isotropy iri ɗaya ne.
(2) homogenity: kauri da nauyin yanki ya kamata ya zama iri ɗaya.
(3) kwanciyar hankali: yana iya tsayayya da lalata kwayoyin halitta, acid da alkali a cikin tushe na ƙasa, canjin yanayin zafi da aikin kwari, kwayoyin cuta da sauran halittu. Kafin a yi amfani da grille na GFRP, yana buƙatar a tara shi na ɗan lokaci, don haka yana buƙatar zama mai jure zafin rana (ultraviolet ray) da ruwan sama.
2. Mechanical Properties
Ƙarfi da elasticity suna da mahimmanci ga samari na inji, saboda suna zaune a kan manyan kayan ƙasa a kan grid fiberglass. Don haka, GFRP grille dole ne ya kasance yana da takamaiman ƙarfi da kaddarorin nakasar grille. Hakanan akwai damar jure kayan da aka tattara, kamar fashewa da tsagewa.
3. Ayyukan na'ura mai aiki da karfin ruwa
Girman pore da aka kafa tsakanin zaruruwa da kauri na grillage FRP suna da babban tasiri akan aikin magudanar ruwa na FRP da tacewa. Girman pore bai kamata kawai ya ba da damar ruwa ya wuce lafiya ba, amma kuma ba zai iya haifar da yashwar ƙasa ba, kuma a lokaci guda, girman pore ya kamata ya kasance da kwanciyar hankali a ƙarƙashin aikin kaya.
Ayyukan grille na FRP yana sa shi kyakkyawan amfani a aikin injiniyan farar hula.
