Monga mtundu watsopano wazinthu zomangira,fiberglass rebar(GFRP rebar) yakhala ikugwiritsidwa ntchito muzomangamanga, makamaka m'mapulojekiti ena omwe ali ndi zofunikira zapadera zokana dzimbiri. Komabe, ilinso ndi zovuta zina, makamaka kuphatikiza:

1.mphamvu yotsika kwambiri:ngakhale mwayifiberglass rebarNdipamwamba kwambiri, mphamvu yake yomaliza kwambiri imakhala yotsika poyerekeza ndi zitsulo zowonjezera, zomwe zimalepheretsa kugwiritsidwa ntchito kwake muzinthu zina zomwe zimafuna mphamvu zambiri zonyamula katundu.

2. Kuwonongeka pang'ono:Pambuyo pofika kumphamvu yomaliza,fiberglass rebaradzakumana Chimaona kuwonongeka popanda chenjezo lodziwikiratu, amene ndi osiyana ndi ductile kuwonongeka makhalidwe zitsulo rebar, ndipo zingabweretse ngozi zobisika chitetezo structural.

3. Vuto lolimba:Ngakhalefiberglass kompositi rebarali ndi kukana kwa dzimbiri kwabwino, magwiridwe ake amatha kuwonongeka m'malo ena, monga kuwonekera kwa nthawi yayitali ku kuwala kwa ultraviolet, chinyezi kapena chilengedwe cha dzimbiri.

4. Vuto la Anchorage:Popeza mgwirizano pakatifiberglass kompositi rebarndipo konkire si yabwino ngati kulimbikitsa zitsulo, mapangidwe apadera amafunikira kuti pakhale anchorage kuti atsimikizire kudalirika kwa kugwirizana kwapangidwe.

5. Mavuto amtengo:mtengo wokwera wafiberglass rebarpoyerekeza ndi ochiritsira zitsulo kulimbikitsa akhoza kuonjezera mtengo okwana ntchito.

6.Zofunikira paukadaulo wapamwamba pakumanga:Monga chuma katundu wafiberglass rebarndizosiyana ndi zolimbitsa zitsulo, kudula kwapadera, kumangiriza ndi njira zomangirira ndizofunikira pomanga, zomwe zimafuna luso lapamwamba la ogwira ntchito yomanga.

7. digiri ya standardization:pakali pano, mlingo wa standardization wafiberglass rebarsichili bwino ngati chilimbikitso chachitsulo chachikhalidwe, chomwe chimalepheretsa kutchuka kwake ndikugwiritsa ntchito pamlingo wina.

8. Vuto lobwezeretsanso:ukadaulo wobwezeretsanso wagalasi fiber kompositi rebarsakadali wosakhwima, zomwe zingakhudze chilengedwe pambuyo pa kusiyidwa.

Mwachidule, ngakhale afiberglass rebarali ndi ubwino wambiri, koma pogwiritsira ntchito zofooka zake ziyenera kuganiziridwa bwino, ndikuchitapo kanthu kuti athetse mavutowa.
